Abstract
BACKGROUND Older adults with dementia often face the risk of potentially inappropriate medication (PIM) use. The quality of PIM evaluation is hindered by researchers' unfamiliarity with evaluation criteria for inappropriate drug use. While traditional machine learning algorithms can enhance evaluation quality, they struggle with the multilabel nature of prescription data. AIM This study aimed to combine six machine learning algorithms and three multilabel classification models to identify correlations in prescription information and develop an optimal model to identify PIMs in older adults with dementia. METHOD This study was conducted from January 1, 2020, to December 31, 2020. We used cluster sampling to obtain prescription data from patients 65 years and older with dementia. We assessed PIMs using the 2019 Beers criteria, the most authoritative and widely recognized standard for PIM detection. Our modeling process used three problem transformation methods (binary relevance, label powerset, and classifier chain) and six classification algorithms. RESULTS We identified 18,338 older dementia patients and 36 PIMs types. The classifier chain + categorical boosting (CatBoost) model demonstrated superior performance, with the highest accuracy (97.93%), precision (95.39%), recall (94.07%), F1 score (95.69%), and subset accuracy values (97.41%), along with the lowest Hamming loss value (0.0011) and an acceptable duration of the operation (371s). CONCLUSION This research introduces a pioneering CC + CatBoost warning model for PIMs in older dementia patients, utilizing machine-learning techniques. This model enables a quick and precise identification of PIMs, simplifying the manual evaluation process.

Abstract
AIMS Alzheimer's disease and related diseases (ADRD) is a progressive and inexorable disease. In France, acetylcholinesterase inhibitors and memantine were reimbursed for subjects with ADRD, until 2 modifications of their reimbursement rate (2012, 2018). We aimed to study the consequences of these measures on ADRD subjects' healthcare use. METHODS We analysed data from the FRA-DEM cohort, including subjects with presumed incident ADRD identified since 2011 in the French health insurance system. We studied the healthcare use of subjects identified with incident ADRD in 2011, 2013, 2015, 2017 and 2019, notably the annual number of defined daily doses of various psychotropic groups. We performed 2 multivariate multinomial logistic regressions with the subcohort year as the dependent variable. RESULTS In total, 165 120 subjects were included. A progressive decrease in exposure to antidementia drugs was observed between 2011 and 2019. Consultations with private neurologists or psychiatrists, and exposure to risperidone, antidepressants and benzodiazepines increased in the 2019 subcohort, following the 2018 reimbursement withdrawal. Meanwhile, the use of nursing/allied healthcare and emergency care increased over the subcohort years, whereas we observed a decrease in general practitioner consultations. CONCLUSION These results suggest increases in private neurologist or psychiatrist consultations and exposure to recommended drugs after the reimbursement withdrawal, contrary to the fears expressed. However, antidementia drug exposure decreased long before the reimbursement modifications, probably due to the growing evidence of the modest effect of these drugs, and exposure to benzodiazepines increased after the reimbursement withdrawal.

Abstract
OBJECTIVE The management of antiseizure treatment in patients with epilepsy relies on the benefit-risk ratio. Data on antiseizure medication (ASM) use in children are limited. We described antiseizure medication use in children with epilepsy (CwE) in France, with a focus on the chronic use of benzodiazepines and related implications. METHODS We conducted a 5-year cohort study from January 2012, using data from the French national health care data system (Système National des Données de Santé). We included CwE identified through International Classification of Diseases, 10th Revision codes and medications from January 2012 to December 2015 and followed them until December 2016. We described ASMs and assessed whether the risk of initiating a polytherapy after a bitherapy depends on whether benzodiazepine was included in the bitherapy. RESULTS We identified 62 885 CwE. Valproate was the most reimbursed ASM (40%), followed by lamotrigine (17.6%), levetiracetam (9.3%), clobazam (6.1%), and carbamazepine (5.8%). Prescriptions were initiated at the hospital in 74.5% of CwE. We observed a decrease in the number of CwE with at least one benzodiazepine reimbursement from 15.3% in 2013 to 10.1% in 2016 (p < .0001). The prevalence of CwE with levetiracetam reimbursements increased, whereas that of CwE with valproate decreased. A switch from a bitherapy to a polytherapy was more likely when the bitherapy included a benzodiazepine (subdistribution hazard ratio [sHR] = 1.20 [1.03-1.39]). SIGNIFICANCE The prevalence of CwE with at least one benzodiazepine reimbursement decreased during the study period. Benzodiazepines were associated with an increased use of subsequent ASM polytherapy.

Abstract
OBJECTIVES Older adults commonly take benzodiazepines (BZDs) that may have long-term adverse cognitive effects. We investigated whether BZD use was related to developing mild cognitive impairment (MCI) or dementia in cognitively normal older adults in the community. SETTING/PARTICIPANTS A population-based cohort (n = 1959) of adults aged 65 and over, recruited from communities of low socioeconomic status. MEASUREMENTS BZD use, Clinical Dementia Rating (CDR), anxiety symptoms, depression symptoms, sleep difficulties, and APOE genotype. DESIGN We examined time from study entry to MCI (CDR = 0.5) and time from study entry to dementia (CDR ≥ 1) in participants who were cognitively normal at baseline (CDR = 0). We used survival analysis (Cox model), adjusted for age, sex, education, sleep, anxiety, and depression. For all the models, we included an interaction term between BZD use and APOE*4. RESULTS Taking BZDs was significantly associated with higher risk of developing MCI, but not of developing dementia. The effect was not affected by APOE genotype. CONCLUSIONS In a population-based sample of cognitively normal older adults, BZD use is associated with developing MCI, but not dementia. BZD use may be a potentially modifiable risk factor for MCI.

Abstract
BACKGROUND Prescribing benzodiazepines to older patients is controversial. Anxiety disorders and benzodiazepines have been associated with dementia, but literature is inconsistent. It is unknown if anxiety treated with a benzodiazepine, compared to anxiety disorder alone is associated with dementia risk. METHODS A retrospective cohort study (n = 72,496) was conducted using electronic health data from 2014 to 2021. Entropy balancing controlled for bias by indication and other confounding factors. PARTICIPANTS Eligible patients were ≥65 years old, had clinic encounters before and after index date and were free of dementia for 2 years prior to index date. Of the 72,496 eligible patients, 85.6% were White and 59.9% were female. Mean age was 74.1 (SD ± 7.1) years. EXPOSURE Anxiety disorder was a composite of generalized anxiety disorder, anxiety not otherwise specified, panic disorder, and social phobia. Sustained benzodiazepine use was defined as at least two separate prescription orders in any 6-month period. MAIN OUTCOME AND MEASURES ICD-9 or ICD-10 dementia diagnoses. RESULTS Six percent of eligible patients had an anxiety diagnosis and 3.6% received sustained benzodiazepine prescriptions. There were 6640 (9.2%) incident dementia events. After controlling for confounders, both sustained benzodiazepine use (HR 1.28, 95% CI: 1.11-1.47) and a diagnosis of anxiety (HR 1.19, 95% CI: 1.06-1.33) were associated with incident dementia in patients aged 65-75. Anxiety disorder with sustained benzodiazepine, compared to anxiety disorder alone, was not associated with incident dementia (HR 1.18, 95% CI: 0.92-1.51) after controlling for confounding. Results were not significant when limiting the sample to those ≥75 years of age. CONCLUSIONS Benzodiazepines and anxiety disorders are associated with increased risk for dementia. In patients with anxiety disorders, benzodiazepines were not associated with additional dementia risk. Further research is warranted to determine if benzodiazepines are associated with a reduced or increased risk for dementia compared to other anxiolytic medications in patients with anxiety disorders.

Abstract
OBJECTIVES The aim of this systematic review is to examine the cognitive impact of psychotropic medications including benzodiazepines, antidepressants, mood stabilizers, antipsychotics, or a combination of these drugs on older adults. DESIGN Systematic review. SETTING We searched Medline, PsycINFO, and Embase through the Ovid platform, CINAHL through EBSCO, and Web of Science. PARTICIPANTS AND INTERVENTIONS Randomized control trials (RCTs) and cohort studies that used a validated scale to measure cognition with a follow-up period of at least six months were included. MEASUREMENT The primary outcome of interest was cognitive change associated with psychotropic medication use. RESULTS A total of 7551 articles were identified from the primary electronic literature search across the five databases after eliminating duplicates. Based on full-text analysis, 27 articles (two RCTs, 25 cohorts) met the inclusion criteria. Of these, nine each examined the impact of benzodiazepines and antidepressants, five examined psychotropic combinations, three on antipsychotic drugs, and one on the effects of mood stabilizers. CONCLUSIONS This is the first systematic review to examine the cognitive impact of multiple psychotropic drug classes in older adults over an extended follow-up period (six months or more) using robust sample sizes, drug-free control groups, and validated cognitive instruments. We found evidence to indicate cognitive decline with the cumulative use of benzodiazepines and the use of antidepressants, especially those with anticholinergic properties among older adults without cognitive impairment at baseline. Further, the use of antipsychotics and psychotropic combinations is also associated with cognitive decline in older adults.

Abstract
Diazepam (DZP) is a long-acting benzodiazepine to treat anxiety or acute alcohol withdrawal. Although this class of drugs should be taken for a short period of time, many patients take them for longer than recommended, which has been linked to an increased risk of dementia and dependence. The present work aimed at using the dual-nozzle system of fused deposition modeling (FDM) 3D printers to prepare tablets with gradual doses of DZP with constant mass and size. Placebo and DZP-loaded filaments were prepared by hot-melt extrusion and used to print the bi-compartmental tablets. Thermal processing allowed the conversion of crystalline DZP to its amorphous counterpart. Tablets with different DZP contents were effectively printed with a mass, thickness and diameter average of 111.6 mg, 3.1 mm, and 6.4 mm, respectively. Microscopic data showed good adhesion between the different layers in the printed tablets. The desired drug contents were successfully achieved and were within the acceptance criteria (European Pharmacopeia). The combination of a placebo and drug-loaded extrudates proved to be beneficial in the production of tablets by FDM for patients in need of drug withdrawal.

Abstract
Objectives To simultaneously estimate how the risk of incident dementia nonlinearly varies with the administration period and cumulative dose of benzodiazepines, the duration of disorders with an indication for benzodiazepines, and other potential confounders, with the goal of settling the controversy over the role of benzodiazepines in the development of dementia. Methods The classical hazard model was extended using the techniques of multiple-kernel learning. Regularised maximum-likelihood estimation, including determination of hyperparameter values with 10-fold cross-validation, bootstrap goodness-of-fit test, and bootstrap estimation of confidence intervals, was applied to cohorts retrospectively extracted from electronic medical records of our university hospitals between 1 November 2004 and 31 July 2020. The analysis was mainly focused on 8160 patients aged 40 or older with new onset of insomnia, affective disorders, or anxiety disorders, who were followed up for 4.10 ± 3.47 years. Results Besides previously reported risk associations, we detected significant nonlinear risk variations over 2-4 years attributable to the duration of insomnia and anxiety disorders, and to the administration period of short-acting benzodiazepines. After nonlinear adjustment for potential confounders, we observed no significant risk associations with long-term use of benzodiazepines. Conclusions The pattern of the detected nonlinear risk variations suggested reverse causation and confounding. Their putative bias effects over 2-4 years suggested similar biases in previously reported results. These results, together with the lack of significant risk associations with long-term use of benzodiazepines, suggested the need to reconsider previous results and methods for future analysis.

Abstract
Background: Diazepam is a classic benzodiazepine drug that has been widely used for disorders such as anxiety, sleep disorders, and epilepsy, over the past 59 years. The study of diazepam has always been an important research topic. However, there are few bibliometric analyses or systematic studies in this field. This study undertook bibliometric and visual analysis to ascertain the current status of diazepam research, and to identify research hotspots and trends in the past 10 years, to better understand future developments in basic and clinical research.Methods: Articles and reviews of diazepam were retrieved from the Web of Science core collection. Using CiteSpace, VOSviewer, and Scimago Graphica software, countries, institutions, authors, journals, references, and keywords in the field were visually analyzed.Results: A total of 3,870 publications were included. Diazepam-related literature had high volumes of publications and citations. The majority of publications were from the USA and China. The highest number of publications and co-citations, among the authors, was by James M Cook. Epilepsia and the Latin American Journal of Pharmacy were the journals with the most publications on diazepam and Epilepsia was the most frequently cited journal. Through a comprehensive analysis of keywords and references, we found that current research on diazepam has focused on its mechanism of action, application in disease, pharmacokinetics, risk, assessment, and management of use, status epilepticus, gamma-aminobutyric acid receptors (GABAR), intranasal formulation, gephyrin, and that ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) is the current research hotspot.Conclusion: Research on diazepam is flourishing. We identified research hotspots and trends in diazepam research using bibliometric and visual analytic methods. The clinical applications, mechanisms of action, pharmacokinetics, and assessment and management of the use of diazepam are the focus of current research and the development trend of future research.

Abstract
Introduction Benzodiazepines (BZDs) are commonly prescribed for anxiety and agitations, which are early symptoms of Alzheimer's disease and related dementias (ADRD). It is unclear whether BZDs causally affect ADRD risk or are prescribed in response to early symptoms of dementia. Methods We replicate prior case-control studies using longitudinal Medicare claims. To mitigate bias from prodromal use, we compare rates of ADRD diagnosis for beneficiaries exposed and unexposed to BZDs for cervical/lumbar pain, stenosis, and sciatica, none of which are associated with dementia. Results Approximately 8% of Medicare beneficiaries used a BZD in 2007, increasing to nearly 13% by 2013. Estimates from case-control designs are sensitive to duration of look-back period, health histories, medication use, and exclusion of decedents. Incident BZD use is not associated with an increased risk of dementia in an "uncontaminated" sample of beneficiaries prescribed a BZD for pain (odds ratios (ORs) of 1.007 [95% confidence interval [CI] = 0.885, 1.146] and 0.986 [95% CI = 0.877, 1.108], respectively, in the 2013 and 2013 to 2015 pooled samples). Higher levels of BZD exposure (>365 days over a 2-year period) are associated with increased odds of a dementia diagnosis, but the results are not statistically significant at the 5% or 10% levels (1.190 [95% CI = 0.925, 1.531] and 1.167 [95% CI = 0.919, 1.483]). Discussion We find little evidence of a causal relation between BZD use and dementia risk. Nonetheless, providers should limit the extended use in elderly populations.

Guo F, Yi L, Zhang W, Bian ZJ, Zhang YB. Association Between Z Drugs Use and Risk of Cognitive Impairment in Middle-Aged and Older Patients With Chronic Insomnia. Front Hum Neurosci 2021; 15:775144. [PMID: 34955792 PMCID: PMC8696350 DOI: 10.3389/fnhum.2021.775144] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Accepted: 11/16/2021] [Indexed: 11/24/2022] Open
Abstract
Background: Benzodiazepines (BZDs) and Non-BZDs (NBZDs) have been widely used for patients with chronic insomnia. Long-term uses of BZDs may cause cognitive impairment and increase the risk for dementia in older patients. NBZD as an agonist of the GABAA receptor complex includes eszopiclone, zopiclone, zolpidem, and zaleplon, also collectively known as Z drugs. However, evaluations for an association between cognitive impairment and Z drug use have been limitedly performed. This study aimed to investigate the association between the risk of cognitive decline and exposure to Z drugs in middle-aged and older patients with chronic insomnia. Methods: Investigations were performed on patients with chronic insomnia who visited the outpatient Department of Neurology, Beijing Friendship Hospital, and were assessed for the global cognitive function (MoCA) and memory (AVLT), executive function (TMT-B), visuospatial ability (CDT), verbal function (BNT-30), and attention (DST). Multiple regression analysis was conducted to determine the independent factors of cognition and evaluated the effect of Z drug use (zolpidem and zopiclone) on cognition. Results: A total of 120 subjects were identified. In our analysis, BZD exposure density (P = 0.025, OR = 1.43, 95% CI, 1.25–1.86) was an independent risk factor of cognitive impairment in middle-aged and older patients with chronic insomnia. Neither Z drug use (P = 0.103) nor Z drug exposure density (P = 0.765) correlated with global cognitive function. Moreover, there was a positive association between Z drug use and attention [(P = 0.002, OR = 0.42, 95% CI, 0.24–0.73)]. Additionally, income level (P = 0.001, OR = 0.23, 95% CI, 0.10–0.53), severity of insomnia (P = 0.019, OR = 1.20, 95% CI, 1.03–1.40) and age (P = 0.044, OR = 1.07, 95% CI, 1.00–1.14) were also independent factors of global cognitive function. Conclusion: BZD exposure density was an independent risk factor of cognitive impairment in middle-aged and older patients with chronic insomnia, but no correlation was found between Z drug use and cognitive impairment. Moreover, the use of Z drugs seemed to be associated with protection for attention. The use for prescription of BZDs, in this case, should be avoided or limited to low doses. Due to the addiction and tolerance, Z drugs should also be prescribed with great caution in middle-aged and elderly patients.

Int J Neuropsychopharmacol 2021; 25:261-268. [PMID: 34727174 PMCID: PMC9017765 DOI: 10.1093/ijnp/pyab073] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2021] [Revised: 10/05/2021] [Accepted: 10/28/2021] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Benzodiazepines (BZDs) and Z-drugs (BZDRs) are among the most prescribed medications for anxiety and insomnia, especially among older adults. Our objective was to investigate the association between the use of BZDRs and the risk of dementia. METHODS A community-based retrospective cohort study was conducted based on the data available from 2002 to 2015 in Catalan Health Service. This cohort included all BZDR users (N = 83 138) and nonusers (N = 84 652) older than 45 years. A minimum 5-year lag window and an adjustment for psychiatric problems were applied for the data analysis. RESULTS The hazard ratio (HR) for the risk of incident dementia among BZDR users was 1.22 (95% CI = 1.15 to 1.31). This risk was not significant after adjusting the data confounding factors (HR = 1.01; 95% CI = 0.94 to 1.08). We observed a higher risk with short-to-intermediate half-life BZDs (HR = 1.11; 95% CI = 1.04 to 1.20) and Z-drugs (HR = 1.20; 95% CI = 1.07 to 1.33) than for intermediate-to-long half-life BZDs (HR = 1.01; 95% CI = 0.94 to 1.08). We demonstrated a higher risk of incident dementia (HR = 1.23; 95% CI = 1.07 to 1.41 and odds ratio = 1.38; 95% CI = 1.27 to 1.50, respectively) in patients who received 91 to 180 defined daily doses (DDDs) and >180 DDDs compared with patients who received <90 DDD. Regarding patient sex, the risk of dementia was higher in women than in men. CONCLUSION We found that the incidence of dementia was not higher among all BZDR users. Short half-life BZDs and Z-drugs increased the risk of dementia at the highest doses, especially in female patients, showing a dose-response relationship.

Br J Clin Pharmacol 2021; 88:1567-1589. [PMID: 34679196 DOI: 10.1111/bcp.15113] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2021] [Revised: 09/30/2021] [Accepted: 10/01/2021] [Indexed: 12/27/2022] Open
Abstract
AIMS Growing evidence suggests an association between the use of sedative-hypnotic medications and risk of dementia. The aim of this study is to examine this association using a meta-analysis approach. METHODS MEDLINE (PubMed) and Scopus were systematically searched for studies published in English only. The quality of studies was evaluated using the Newcastle-Ottawa scale, and an overall odds ratio was pooled using a random-effects model. RESULTS A total of 35 articles were included in the analysis. Pooled odds ratios (ORs) for dementia from all records were (OR; 1.33, 95% CI 1.19-1.49) for benzodiazepine (BZD) combined use (Subgroup-1), (OR: 1.46, 95% CI 1.23-1.73) for short-acting BZD use (Subgroup-2), (OR: 1.72, 95% CI 1.48-1.99) for long-acting BZD use (Subgroup-3), (OR: 1.13, 95% CI 0.97-1.32) for BZDs without specification of duration of action (Subgroup-4), (OR: 1.64, 95% CI 1.13-2.38) for the combined BZDs and Z-drugs, (OR: 1.43, 95% CI 1.17-1.74) for Z-drugs only, (OR: 1.14, 95% CI 0.88-1.46) for antidepressant use, (OR: 0.97, 95% CI 0.68-1.39) for antipsychotic use and (OR: 0.98, 95% CI 0.85-1.13) for anticonvulsant use. When sensitivity analysis was performed, association between overall use of BZDs and short-acting BZDs with the increased risk of dementia disappeared after exclusion of studies that were not adjusted for age covariate (OR: 1.2, 95% CI 1.0-1.44) and (OR: 1.22, 95% CI 0.75-2.01), respectively. Adjustment for protopathic bias by introduction of a lag period showed no evidence of increased risk of dementia with the use of BZDs (Subgroup-1) (OR: 1.14, 95% CI 0.82-1.58), Z-drugs (OR: 1.29, 95% CI 0.78-2.13), and combined BZDs and Z-drugs (OR: 1.51, 95% CI 0.91-2.53). Combined use of BZDs and Z-drugs showed more positive association when only studies of non-user design were analysed (OR: 2.75, 95% CI 2.23-3.39). CONCLUSIONS All the investigated sedative-hypnotics showed no association with increased risk of dementia except for BZDs. However, the observed association with BZDs did not persist after exclusion of studies with potential reverse causation and confounding by indication. Therefore, this association needs to be assessed carefully in future research.

Abstract
BACKGROUND There is a current trend to reassess the adequacy of care. Establishing top five lists by involving patients is one way to address medical overuse. The objective of this study was to establish a patients' top five list in general practice in France. The secondary objective was to identify selection criteria. METHOD Patients from the web-based cohort GrippeNet.fr were invited to establish their top five list from 15 care procedures previously selected by general practitioners on the basis of medical overuse. The care procedures were presented on a web-interface with guides written with the help of a patient association. A questionnaire was used to explore factors that may have influenced the choices of the participants. RESULTS In total, 691 patients established the following top five list: 1/ Prescription of antibiotics for acute bronchitis, nasopharyngitis, otitis media with effusion, or uncomplicated influenza; 2/ Prescription of benzodiazepine and benzodiazepine-like agents for insomnia, generalised anxiety and all indications for older patients; 3/ Prescription of a homeopathic treatment (Influenzinum) for flu prevention; 4/ Prescription of antitussive or expectorant agents for acute cough or acute bronchitis care; 5/ Prescription of statins for the primary prevention of cardio-vascular risk in older patients. More than 70% of participants gave importance to the recommendations, effectiveness, and tolerance of the care procedures, whereas only half considered the cost. CONCLUSION This study is the first to establish a patient's top-five list in general practice. This list provides direction for deciding the main targets in limiting medical overuse.

Abstract
This study aimed to investigate the risk and prognosis of Alzheimer's disease (AD) and vascular dementia (VaD) in patients with insomnia using the National Health Insurance Service database covering the entire population of the Republic of Korea from 2007 to 2014. In total, 2,796,871 patients aged 40 years or older with insomnia were enrolled, and 5,593,742 controls were matched using a Greedy digit match algorithm. Mortality and the rate of admission to a long-term care facility were estimated using multivariable Cox analysis. Of all patients with insomnia, 138,270 (4.94%) and 26,706 (0.96%) were newly diagnosed with AD and VaD, respectively. The incidence rate ratios for AD and VaD were 1.73 and 2.10, respectively, in patients with insomnia compared with those without. Higher mortality rates and long-term care facility admission rates were also observed in patients with dementia in the insomnia group. Known cardiovascular risk factors showed interactions with the effects of insomnia on the risk of AD and VaD. However, the effects of insomnia on the incidence of AD and VaD were consistent between the groups with and without cardiovascular risk factors. Insomnia is a medically modifiable and policy-accessible risk factor and prognostic marker of AD and VaD.

Abstract
Lateral flow assays (lateral flow immunoassays and nucleic acid lateral flow assays) have experienced a great boom in a wide variety of early diagnostic and screening applications. As opposed to conventional examinations (High Performance Liquid Chromatography, Polymerase Chain Reaction, Gas chromatography-Mass Spectrometry, etc.), they obtain the results of a sample's analysis within a short period. In resource-limited areas, these tests must be simple, reliable, and inexpensive. In this review, we outline the production process of antibodies against drugs of abuse (such as heroin, amphetamine, benzodiazepines, cannabis, etc.), used in lateral flow immunoassays as revelation or detection molecules, with a focus on the components, the principles, the formats, and the mechanisms of reaction of these assays. Further, we report the monoclonal antibody advantages over the polyclonal ones used against drugs of abuse. The perspective on aptamer use for lateral flow assay development was also discussed as a possible alternative to antibodies in view of improving the limit of detection, sensitivity, and specificity of lateral flow assays.

Non-benzodiazepine hypnotic use for sleep disturbance in people aged over 55 years living with dementia: a series of cohort studies. Health Technol Assess 2021; 25:1-202.

Abstract
BACKGROUND Sleep disturbance affects around 60% of people living with dementia and can negatively affect their quality of life and that of their carers. Hypnotic Z-drugs (zolpidem, zopiclone and zaleplon) are commonly used to treat insomnia, but their safety and efficacy have not been evaluated for people living with dementia. OBJECTIVES To estimate the benefits and harms of Z-drugs in people living with dementia with sleep disturbance. DESIGN A series of observational cohort studies using existing data from (1) primary care linked to hospital admission data and (2) clinical cohort studies of people living with dementia. DATA SOURCES Primary care study - Clinical Practice Research Datalink linked to Hospital Episode Statistics and Office for National Statistics mortality data. Clinical cohort studies - the Resource Use and Disease Course in Dementia - Nursing Homes (REDIC) study, National Alzheimer's Coordinating Centre (NACC) clinical data set and the Improving Well-being and Health for People with Dementia (WHELD) in nursing homes randomised controlled trial. SETTING Primary care study - 371 primary care practices in England. Clinical cohort studies - 47 nursing homes in Norway, 34 Alzheimer's disease centres in the USA and 69 care homes in England. PARTICIPANTS Primary care study - NHS England primary care patients diagnosed with dementia and aged > 55 years, with sleep disturbance or prescribed Z-drugs or low-dose tricyclic antidepressants, followed over 2 years. Clinical cohort studies - people living with dementia consenting to participate, followed over 3 years, 12 years and 9 months, for REDIC, NACC and WHELD, respectively. INTERVENTIONS The primary exposure was prescription or use of Z-drugs. Secondary exposures included prescription or use of benzodiazepines, low-dose tricyclic antidepressants and antipsychotics. MAIN OUTCOME MEASURES Falls, fractures, infection, stroke, venous thromboembolism, mortality, cognitive function and quality of life. There were insufficient data to investigate sleep disturbance. RESULTS The primary care study and combined clinical cohort studies included 6809 and 18,659 people living with dementia, with 3089 and 914 taking Z-drugs, respectively. New Z-drug use was associated with a greater risk of fractures (hazard ratio 1.40, 95% confidence interval 1.01 to 1.94), with risk increasing with greater cumulative dose (p = 0.002). The hazard ratio for Z-drug use and hip fracture was 1.59 (95% confidence interval 1.00 to 2.53) and for mortality was 1.34 (95% confidence interval 1.10 to 1.64). No excess risks of falls, infections, stroke or venous thromboembolism were detected. Z-drug use also did not have an impact on cognition, neuropsychiatric symptoms, disability or quality of life. LIMITATIONS Primary care study - possible residual confounding because of difficulties in identifying patients with sleep disturbance and by dementia severity. Clinical cohort studies - the small numbers of people living with dementia taking Z-drugs and outcomes not necessarily being measured before Z-drug initiation restricted analyses. CONCLUSIONS We observed a dose-dependent increase in fracture risk, but no other harms, with Z-drug use in dementia. However, multiple outcomes were examined, increasing the risk of false-positive findings. The mortality association was unlikely to be causal. Further research is needed to confirm the increased fracture risk. Decisions to prescribe Z-drugs may need to consider the risk of fractures, balanced against the impact of improved sleep for people living with dementia and that of their carers. Our findings suggest that when Z-drugs are prescribed, falls prevention strategies may be needed, and that the prescription should be regularly reviewed. FUTURE WORK More research is needed on safe and effective management strategies for sleep disturbance in people living with dementia.

[PMID: 33248901 DOI: 10.1016/j.sleep.2020.11.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/28/2020] [Revised: 09/06/2020] [Accepted: 11/03/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND Sleep difficulties are common among older adults, and clinical management of sleep difficulties commonly includes sleep medication (pharmacological and non-pharmacological). Our research examines sleep medication use and incident dementia over 8 years using nationally representative data from older adults ages 65 years and older in the United States. METHODS We used data collected from the National Health and Aging Trends Study (NHATS), a nationally-representative longitudinal study of Medicare beneficiaries. Routine sleep medication use (pharmacological and non-pharmacological) was defined as use "most nights" or "every night." Participants were screened for dementia with validated instruments that assessed memory, orientation, and executive function. We conduct prospective analyses to examine the relationship between routine sleep medication use and incident dementia using Cox proportional hazards modeling and estimated survival curves. Analyses controlled for age, sex, marital status, education, and chronic conditions. RESULTS Among respondents at baseline (n = 6373), most participants (21%) were age 70-74 years of age. Participants were 59% female and the sample comprised non-Hispanic White (71%). At baseline, 15% of our study sample reported using sleep medication routinely, which is representative of 4.6 million older adults in the US. Covariate adjusted proportional hazard models revealed that routinely using sleep medication was associated with incident dementia (HR = 1.30, 95%CI: 1.10 to 1.53, p < 0.01). CONCLUSIONS Our study observed, in a nationally representative study of older adults in the US across 8 years of data that 15% of older adults report routinely using sleep medication, yet routine use of sleeping medication was associated with incident dementia across the follow-up interval. Future research may examine behavioral approaches to improving sleep among older adults.

Impact of benzodiazepine consumption reduction on future burden of dementia. Sci Rep 2020; 10:14666. [PMID: 32887900 PMCID: PMC7474098 DOI: 10.1038/s41598-020-71482-0] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2019] [Accepted: 07/30/2020] [Indexed: 11/08/2022] Open
Abstract
Dementia is a major public health issue worldwide and chronic use of benzodiazepine, which is very frequent in northern countries, was found to be a risk factor of dementia. This work aims at evaluating the impact of a reduction in chronic use of benzodiazepine on the future burden of dementia in France. Using estimations of dementia incidence and of benzodiazepine use and nation-wide projections of mortality and population sizes, a Monte Carlo approach based on an illness-death model provided projections of several indicators of dementia burden. With no change in benzodiazepine consumption, the prevalence of dementia between age 65 and 99 in France in 2040 was estimated at 2.16 millions (95% confidence interval (CI) 1.93-2.38), with a life expectancy without dementia at 65 years equal to 25.0 years (24.7-25.3) for women and 23.8 years (23.5-24.2) for men. Assuming a disappearance of chronic use of benzodiazepine in 2020, the prevalence would be reduced by about 6.6% in 2040 and the life expectancy without dementia would increase by 0.99 (0.93-1.06) year among women and 0.56 (0.50-0.62) among men. To conclude, a modest but significant reduction in future dementia burden could be obtained by applying current recommendation for duration of benzodiazepine use.

Abstract
Benzodiazepines are commonly used for behavioral and psychiatric symptoms of dementia, despite their numerous adverse effects and the lack of evidence regarding their efficacy in this context. We studied longitudinal benzodiazepines exposure in incident cases of Alzheimer's disease and related syndromes (ADRS) in France. We used a cohort of incident ADRS patients identified in 2012 within the national health data system. Benzodiazepines exposure was measured 1 year before, to 5 years after ADRS identification. Quarterly benzodiazepines prevalence and incidence were computed. We identified factors associated with long half-life benzodiazepines initiation. A total of 106 508 subjects were included. Quarterly benzodiazepines prevalence was stable (around 25%) but we saw an important decrease in long half-life benzodiazepines compensated by an increase in short half-life benzodiazepines. In most benzodiazepine initiations, the first episode lasted less than 3 months. Factors associated with initiating a long half-life benzodiazepine were young age, male gender, no registration with ADRS as a long-term disease, having consulted an ADRS specialist, antipsychotic reimbursement before the index date, no admission in nursing home. Prevalence of benzodiazepines use remains high in subjects with ADRS despite guidelines for their avoidance. However, indicators regarding benzodiazepine initiations (duration, benzodiazepine type) suggest some caution in their use.

Abstract
BACKGROUND Hypnotics (HYP) and benzodiazepines (BZD) are medicines prescribed for the insomnia treatment. Many patients present difficulties in discontinuing the treatment once established. Melatonin (MLT) has been prescribed as a treatment for BZD/HYP detoxification. AIMS The primary objective of this systematic review is to assess the efficacy of MLT and MLT agonists (melatoninergics) in improving the rate of BZD and/or HYP discontinuation among adults with primary insomnia attempting to discontinue BZD and/or HYP. The secondary objective is to evaluate the partial efficacy of melatoninergic drugs in the discontinuation of BZD and/or HYP consumption in subjects that could not stop their consumption. METHOD A search on Web of Science and Scopus was carried out from database inception to July 1st, 2019. RESULTS Three hundred and forty-nine articles were identified but only four were included in the final review. Two were cohort prospective, one placebo-control double blind and one double blind placebo-control cross-over designed study. Total withdrawal (TW) ranged from 0% to 25% in the placebo arm and from 64.3% to 77.8% in the MLT arm. In cohort studies TW figures ranged from 30.8% to 65%. Partial withdrawal ranged between 20% and 30.8% of patients that did not achieve TW with reduction figures of diazepam equivalent dose ranging from 25% to 75%. CONCLUSION MLT has a place in the physician armamentarium to treat the suspension/reduction of BZD/HYP consumption in patients with primary insomnia.

Abstract
OBJECTIVE The association between benzodiazepine use and the risk of cognitive impairment or dementia has been controversial. Our study aims to detect this association through a case/non-case method using the Korea Institute of Drug Safety & Risk Management-Korea adverse event reporting system database (KIDS-KD) between 2007 and 2016. METHODS Cases were adverse event (AE)-pairs with suspected cognitive impairment or dementia. 10 non-cases were matched to each case on age and sex. Exposure was defined as use of benzodiazepines, including long-, intermediate-, and short-acting benzodiazepine. We conducted multivariable logistic regression analyses to estimate reporting odds ratios (ROR) and 95% confidence intervals (CI). RESULTS Of the 1,086,584 AE-pairs, 887 cases were suspected AE-pairs of cognitive impairment or dementia, and 775,444 non-cases were selected. Benzodiazepine use was associated with increased AE-pairs of cognitive impairment or dementia when assessed using those with certain, probable, and/or possible in causality assessments (ROR=2.69, 95% CI=1.66-4.38). Higher ROR estimates were shown in female (2.33, 1.48-3.67) and in those with polypharmacy (2.20, 1.35-3.57). Dementia safety profiles were inconsistent across individual benzodiazepine components. CONCLUSION These results suggest the potentially increased association between benzodiazepine use and cognitive impairment or dementia in female and those with polypharmacy. Inconsistent safety profiles of benzodiazepine components should be further investigated.

Abstract
OBJECTIVE Benzodiazepines and Z-drugs are two of the most prescribed agents worldwide. However, because of their cognitive side effects, the question of their influence on the risk of dementia has been raised. The authors examined the association of benzodiazepines, Z-drugs, and other anxiolytics with incident dementia in patients with affective disorders. METHODS The authors conducted a cohort and nested case-control study of 235,465 patients over age 20 who were identified in the Danish National Patient Registry as having had a first-time hospital contact for an affective disorder between 1996 and 2015. From the Danish National Prescription Registry, information was obtained on all prescriptions for benzodiazepines, Z-drugs, and other anxiolytics, and patients were followed for incident dementia (defined by hospital discharge diagnosis or acetylcholinesterase inhibitor use). Cox proportional hazards and conditional logistic regression models were used to calculate hazard ratios and odds ratios with adjustment for sociodemographic and clinical variables. RESULTS A total of 75.9% (N=171,287) of patients had any use of benzodiazepines or Z-drugs, and during the median follow-up of 6.1 years (interquartile range, 2.7-11), 9,776 (4.2%) patients were diagnosed with dementia. Any use of benzodiazepines or Z-drugs showed no association with dementia after multiple adjustments in either the cohort analysis or a nested case-control design. In the cohort analysis, the number of prescriptions and the cumulated dose of benzodiazepines or Z-drugs at baseline were not associated with dementia. In the nested case-control study, where prescriptions were counted from 1995 until 2 years before the index date, there was a slightly higher odds ratio of dementia in patients with the lowest use of benzodiazepines or Z-drugs (odds ratio=1.08, 95% CI=1.01, 1.15) compared with no lifetime use. However, patients with the highest use had the lowest odds of developing dementia (odds ratio=0.83, 95% CI=0.77, 0.88). CONCLUSIONS This large cohort study did not reveal associations between use of benzodiazepines or Z-drugs and subsequent dementia, even when exposures were cumulated or divided into long- and short-acting drugs. Some results were compatible with a protective effect.

Abstract
OBJECTIVE To evaluate the association between use of benzodiazepines and incident dementia. METHODS Analytical prospective nested case-control study for which the Spanish database for pharmacoepidemiological research in primary care (BIFAP) of the Spanish Agency of Medicines and Medical Devices (AEMPS) was used. A total of 15,212 subjects diagnosed with dementia of the Alzheimer type and 62,397 controls were identified. Exposure was retrieved retrospectively with a 3-year lag time before the index date. Adjusted odd ratios (OR) were calculated. RESULTS Benzodiazepines use increased the risk of suffering Alzheimer's disease (OR=1.05, 95% CI, 1.01-1.10). No statistical differences were shown between short-acting and long-acting drugs. The risk is more evident with longer exposure times. CONCLUSIONS There seems to be a weak association between benzodiazepine use and the development of dementia, the risk increases with greater exposure.

Abstract
Background: To assess the association between anxiety and risk of vascular dementia (VaD), as well as potential sex differences, in a community-based cohort. Methods: A random sample of 4057 dementia-free community participants aged 55 or older, from the longitudinal, community-based Zaragoza Dementia and Depression Project (ZARADEMP) study were followed for 4.5 years. Geriatric Mental State B (GMS)-Automated Geriatric Examination for Computer Assisted Taxonomy (AGECAT) was used for the assessment and diagnosis of anxiety, and a panel of research psychiatrists diagnosed the incident cases of VaD according to DSM-IV (Diagnostic and Statistical Manual of mental disordes). Multivariate survival analysis with competing risk regression model was performed. Results: In men, the incidence rate of VaD was significantly higher among anxiety subjects compared with non-anxiety subjects (incidence rate ratio (IRR) (95% confidence interval (CI)): 3.24 (1.13-9.35); p = 0.029), and no difference was observed in women (IRR (95%CI): 0.68 (0.19-2.23); p = 0.168). In the multivariate model, for men, cases of anxiety had 2.6-fold higher risk of VaD (subdistribution hazard ratio (SHR): 2.61; 95%CI: 0.88-7.74) when all potential confounding factors were controlled, with no statistical significance (p = 0.084), but a clinically relevant effect (Cohen's d: 0.74). No association was found in women. Conclusions: In men, but not in women, risk of VaD was higher among individuals with anxiety, with a clinically relevant effect. Potential anxiety-related preventive interventions for VaD might be tailored to men and women separately.

Abstract
Benzodiazepines (BZDs) and Z-drugs are compounds widely prescribed in medical practice due to their anxiolytic, hypnotic, and muscle relaxant properties. Yet, their chronic use is associated with cases of abuse, dependence, and relapse in many patients. Furthermore, elderly people are susceptible to alterations in pharmacodynamics, pharmacokinetics as well as to drug interaction due to polypharmacy. These situations increase the risk for the appearance of cognitive affectations and the development of pathologies like Alzheimer's disease (AD). In the present work, there is a summary of some clinical studies that have evaluated the effect of BZDs and Z-drugs in the adult population with and without AD, focusing on the relationship between their use and the loss of cognitive function. Additionally, there is an assessment of preclinical studies focused on finding molecular proof on the pathways by which these drugs could be involved in AD pathogenesis. Moreover, available data (1990-2019) on BZD and Z-drug use among elderly patients, with and without AD, was compiled in this work. Finally, the relationship between the use of BZD and Z-drugs for the treatment of insomnia and the appearance of AD biomarkers was analyzed. Results pointed to a vicious circle that would worsen the condition of patients over time. Likewise, it put into relevance the need for close monitoring of those patients using BZDs that also suffer from AD. Consequently, future studies should focus on optimizing strategies for insomnia treatment in the elderly by using other substances like melatonin agonists, which is described to have a much more significant safety profile.

Abstract
The utilization of benzodiazepines (BZDs) and z-hypnotics has substantially increased with the aging of the population, but the risk of BZDs and z-hypnotics in the development of dementia remains a strong concern. This cohort study aimed to evaluate the risk of BZDs and z-hypnotics for subsequent dementia development with a special consideration of their half-lives and the concomitant use of these medications. People aged 65 years and older who were newly prescribed oral BZDs or z-hypnotics between 2003 and 2012 were identified from Taiwan's National Health Insurance Research Database. All BZDs were categorized as long-acting drugs (≥ 20 h) or short-acting drugs (< 20 h) for further comparisons, and data were collected on a quarterly basis, starting on the first date of drug prescription and ending on the date of death, occurrence of dementia, or end of the follow-up period (December 31, 2012), whichever came first. All dementia events except vascular dementia occurring during the follow-up period were identified. Among 260,502 eligible subjects, short-acting BZDs and z-hypnotics users were at greater risk of dementia than long-acting users [adjusted odds ratio (95% confidence interval) in short-acting BZD users, 1.98 (1.89-2.07); z-hypnotic users, 1.79 (1.68-1.91); and long-acting BZD users, 1.47 (1.37-1.58)]. In addition, subjects concomitantly using 2 or more BZDs or z-hypnotics had a higher risk of dementia than those who used 1 of these drugs (4.79 (3.95-5.81)). The use of BZDs and z-hypnotics was strongly associated with the risk of dementia development, especially the short-acting BZDs, z-hypnotics, and concomitant use of multiple agents. These findings deserve further interventional studies for clarification.

Abstract
OBJECTIVES Developing scalable strategies for the early identification of Alzheimer's disease and related dementia (ADRD) is important. We aimed to develop a passive digital signature for early identification of ADRD using electronic medical record (EMR) data. DESIGN A case-control study. SETTING The Indiana Network for Patient Care (INPC), a regional health information exchange in Indiana. PARTICIPANTS Patients identified with ADRD and matched controls. MEASUREMENTS We used data from the INPC that includes structured and unstructured (visit notes, progress notes, medication notes) EMR data. Cases and controls were matched on age, race, and sex. The derivation sample consisted of 10 504 cases and 39 510 controls; the validation sample included 4500 cases and 16 952 controls. We constructed models to identify early 1- to 10-year, 3- to 10-year, and 5- to 10-year ADRD signatures. The analyses included 14 diagnostic risk variables and 10 drug classes in addition to new variables produced from unstructured data (eg, disorientation, confusion, wandering, apraxia, etc). The area under the receiver operating characteristics (AUROC) curve was used to determine the best models. RESULTS The AUROC curves for the validation samples for the 1- to 10-year, 3- to 10-year, and 5- to 10-year models that used only structured data were .689, .649, and .633, respectively. For the same samples and years, models that used both structured and unstructured data produced AUROC curves of .798, .748, and .704, respectively. Using a cutoff to maximize sensitivity and specificity, the 1- to 10-year, 3- to 10-year, and 5- to 10-year models had sensitivity that ranged from 51% to 62% and specificity that ranged from 80% to 89%. CONCLUSION EMR-based data provide a targeted and scalable process for early identification of risk of ADRD as an alternative to traditional population screening. J Am Geriatr Soc 68:511-518, 2020.

Abstract
Background: The use of benzodiazepines in relation to cognitive decline remains an area of controversy in aging populations. Objective: This study aims to evaluate the risk of cognitive impairment–not dementia (CIND), Alzheimer disease (AD), and all-cause dementia with benzodiazepine use. The effect modification by sex was also investigated. Methods: Data come from the Canadian Study of Health and Aging, a 10-year multicentric study involving 10 263 participants randomly selected, 65 years and older, living in the community and in institutions. Current exposure to benzodiazepines was assessed in a face-to-face interview or self-reported in a questionnaire. Cox proportional hazard regression models, using age as time scale, were conducted to estimate hazard ratios, with adjustment for sex, education, smoking, alcohol intake, depression, physical activity, nonsteroidal anti-inflammatory drug use, and vascular comorbidities. Results: Data sets included 5281 participants for dementia as the outcome, 5015 for AD, and 4187 for CIND. Compared with nonusers, current use of benzodiazepines was associated with an increased risk of CIND (hazard ratio = 1.36; 95% CI = 1.08-1.72) in the simplest model. Results remained similar in the fully adjusted model (hazard ratio = 1.32; 95% CI = 1.04-1.68). There was no association between benzodiazepine use and the risk of dementia or AD. All these effects were similar between men and women. Conclusion and Relevance: Benzodiazepine use in older people from the general population is related to subsequent occurrence of cognitive dysfunction but not implicated in the pathogenesis of dementia or AD. Caution should be exercised when prescribing benzodiazepines to preserve global cognitive function.

Abstract
Many risk factors are known to induce or precipitate dementia. Drugs acting via different mechanisms can modulate cognitive performance and exert either beneficial or deleterious effects on cognition through functional or neuropathological mechanisms. This review discusses the association between several classes of drugs and cognitive impairment and dementia risk. These drugs can be divided into drugs targeting CNS disorders (e.g., anticholinergic drugs, antiepileptics, antipsychotics, benzodiazepines, and opioids) and drugs targeting non‐CNS disorders (e.g., antidiabetics, antihypertensives, proton pump inhibitors, and statins). Furthermore, we sought to highlight the pharmacological mechanisms underlying their possible detrimental or beneficial effects on cognition. Anticholinergic and antiepileptic drugs were excluded from this review because their effects on cognition are well known. Studies investigating benzodiazepines have revealed an increased risk of dementia. Conclusions on dementia risk or cognitive impairment regarding opioids and antipsychotic drugs are difficult to draw. These different classes appear to impair cognition not by a single clear mechanism of action specific to each class but by several relatively interdependent and interconnected mechanisms (e.g., impaired neurotransmission, neuroinflammation, neuronal death, oxidative stress, or interactions with dementia‐related pathways). The dementia risk initially associated with the use of proton pump inhibitors might have been overestimated. In contrast, statins, antihypertensive medications, and antidiabetics could potentially decrease the risk of dementia and cognitive impairment by acting in ways opposite to the mechanisms cited above.Linked ArticlesThis article is part of a themed section on Therapeutics for Dementia and Alzheimer's Disease: New Directions for Precision Medicine.

Abstract
OBJECTIVE Existing evidence on long-term psychotropic polypharmacy in older people is scarce despite serious safety concerns regarding this issue. This study aims to identify distinct trajectories of longitudinal psychotropic agent use and to examine the association with the risk of mortality and unplanned hospitalization according to distinct trajectories. DESIGN A retrospective longitudinal cohort study based on data from Taiwan's National Health Insurance Research Database (NHIRD). SETTING AND PARTICIPANTS A population-based study including 39,803 eligible participants aged 65 years or older who were newly prescribed oral psychotropic agents in 2004. MEASURES We assessed 5 years of monthly consumption of psychotropic agents among eligible participants and used group-based trajectory modeling to identify distinct groups of longitudinal psychotropic use. Cox proportional hazards models were used to examine the association between distinct trajectories of longitudinal psychotropic agent use and subsequent 1- and 3-year unplanned hospitalization and all-cause mortality. RESULTS Among 39,803 eligible participants, we identified 5 trajectories of longitudinal psychotropic agent use over a 5-year follow-up period: sustained intense (7.1%), moderate increasing (12.1%), decreasing (13.4%), slowly increasing (15.7%), and infrequent users (51.6%). Moderate increasing and sustained intense use were associated with significantly higher risks of unplanned hospitalization [moderate increasing use: hazard ratio [HR] 1.30, 95% confidence interval (CI) 1.18-1.44; sustained intense use: HR 1.40, 95% CI 1.24-1.58] and all-cause mortality (moderate increasing use: HR 1.25, 95% CI 1.09-1.44; sustained intense use: HR 1.32, 95% CI 1.12-1.56) than infrequent use. Similar results were observed at 3 years of follow-up. CONCLUSIONS/IMPLICATIONS Older people with moderately increasing and sustained intense use of psychotropic agents over time had higher risks of unplanned hospitalization and mortality. Tracking older people's use of psychotropic agents over time may help to identify individuals at greatest risk of unplanned hospitalization and mortality.

Abstract
Previous estimates of whether long-term exposure to benzodiazepines increases dementia risk are conflicting and are compromised by the difficulty of controlling for confounders and by reverse causation. We investigated how estimates for the association between benzodiazepine use and later dementia incidence varied based on study design choices, using a case-control study nested within the United Kingdom's Clinical Practice Research Datalink. A total of 40,770 dementia cases diagnosed between April 2006 and July 2015 were matched on age, sex, available data history, and deprivation to 283,933 control subjects. Benzodiazepines and Z-drug prescriptions were ascertained in a drug-exposure period 4-20 years before dementia diagnosis. Estimates varied with the inclusion of new or prevalent users, with the timing of covariate ascertainment, and with varying time between exposure and outcome. There was no association between any new prescription of benzodiazepines and dementia (adjusted odds ratio (OR) = 1.03, 95% confidence interval (CI): 1.00, 1.07), whereas an inverse association was observed among prevalent users (adjusted OR = 0.91, 95% CI: 0.87, 0.95), although this was likely induced by unintentional adjustment for colliders. By considering the choice of confounders and timing of exposure and covariate measurement, our findings overall are consistent with no causal effect of benzodiazepines or Z-drugs on dementia incidence.

Abstract
BACKGROUND In 2015, Portugal was the OECD country with the highest reported consumption of BZD. Physician's perceptions and attitudes regarding BZD are main determinants of related prescription habits. This study aimed to characterize beliefs and attitudes of Portuguese physicians regarding the prescription, management challenges, benefits, risks and withdrawal effects of BZD. METHODS A cross-sectional, observational study with online data collection through anonymous self-administered questionnaire. Physicians registered with the Portuguese Medical Association were invited to participate through direct e-mail message. Physicians were asked to give their opinion (using a 5-points Likert scale) regarding the prescription of BZD, their benefits and risks in the management of insomnia and anxiety, the possible adverse effects of chronic use and alternative non-pharmacologic approaches. Descriptive statistics were used and groups were compared through logistic regression. RESULTS A total of 329 physicians participated in the study (56% family physicians). Mean age was 44.10 ± 15.2 years, with 19.03 ± 14.9 years of clinical experience. Fifty eight percent of participants were female. Physicians reported BZD's negative impact on cognitive function (89%), association with road traffic accidents (88%) and falls (79%). Also, 58% shared the belief that chronic use is justified if the patient feels better and without adverse events. Although 68% reported to feel capable of helping patients to reduce or stop BZD, 55% recognized difficulties in motivating them. Compared to other medical specialists (altogether), family physicians were significantly more aware about the adverse effects of BZD and considered that chronic use may not be justified. Conversely, more family physicians expressed concerns about their skills to motivate patients engaging in withdrawal programs and to support them during the process. CONCLUSION Our results show that physicians' awareness about risks of BZD chronic use is adequate though their attitudes and self-perceived skills towards promoting BZD withdrawal can be improved. Interventions in primary care are needed to capacitate physicians to better motivate patients for BZD withdrawal.

Abstract
OBJECTIVES To investigate whether clinically relevant anxiety increased the risk for developing Alzheimer's disease (AD) while controlling for the presence of depression and other confounders; and to report the population attributable fraction (PAF) associated with anxiety disorder. METHOD We used data from the longitudinal, community-based Zaragoza Dementia and Depression (ZARADEMP) study. A random sample of 4057 dementia-free community dwellers aged ≥55 years were followed for 4.5 years. The Geriatric Mental State-Automated Geriatric Examination for Computer Assisted Taxonomy package was used for the diagnosis of clinically significant cases and subcases of anxiety; and AD was diagnosed by a panel of research psychiatrists according to DSM-IV criteria. Multivariate survival analysis with competing risk regression model was performed. RESULTS We observed a significant association between anxiety cases at baseline and AD risk in the univariate analysis that persisted in the fully adjusted model (SHR: 3.90; 95% CI: 1.59-9.60; p = 0.003), with a PAF for AD of 6.11% (95% CI: 1.30%-16.17%). No significant association between 'subcases' of anxiety at baseline and AD risk was found. LIMITATIONS Data on apolipoprotein E were not available. The hospital-based diagnosis was not completed in all cases of dementia. CONCLUSION Late-life, clinically significant anxiety (but not subclinical anxiety) seems to increase the risk of AD, independently of the effect of several confounders, including depression. Taking into account the high prevalence of anxiety among the elderly, future studies are warranted to determine potential risk reduction of AD.

Abstract
Background Sedative-hypnotics (SHs) are widely used in France but there are no available data addressing their prescription specifically in hospitalized older patients. The objective is thus to determine the cumulative incidence of sedative-hypnotic (SH) medications initialized during a hospital stay of older patients, the proportion of SH renewal at discharge among these patients and to study associated risk factors. Methods We conducted a retrospective observational study in six internal medicine units and six acute geriatric units in eight hospitals (France). We included 1194 inpatients aged 65 and older without SH medications prior to hospitalization. Data were obtained from patients’ electronic pharmaceutical records. Primary outcome was the cumulative incidence of SH initiation in the study units. Secondary outcomes were the proportion of SH renewal at discharge and risk factors for SH initiation and renewal at discharge (patient characteristics, hospital organization). A Cox regression model was used to study risk factors for SH initiation. A mixed effects logistic regression was used to study risk factors for SH renewal at discharge. Results SH initiation occurred in 21.5% of participants 20 days after admission. SH renewal at discharge occurred in 38.7% of patients who had initiated it during their stay and were discharged home and in 56.0% of patients discharged to rehabilitation facilities. Neither patients’ characteristics nor hospital organization patterns was associated with SH initiation. SH initiation after the first six days after admission was associated with a lower risk of SH renewal in patients discharged to rehabilitation facilities (OR = 0.19, 95% CI: [0.04–0.80]). Conclusions Hospitalization is a period at risk for SH initiation. The implementation of interventions promoting good use of SHs is thus of first importance in hospitals. Specific attention should be paid to patients discharged to rehabilitation facilities.

Abstract
Emerging evidence indicates that the use of benzodiazepines among older adults may increase the risk of development of dementia. A review of the literature identified 13 studies investigating this link. Eight studies found a positive association between the use of benzodiazepines and development of dementia. Two studies found no such association, two had mixed results and one study found that benzodiazepine use reduced the incidence of dementia. As none of these studies were controlled prospective studies, causality could not be ascertained. The association identified between the use of benzodiazepines and the development of dementia is a cause for concern among older adults.

Abstract
Psychotropic drugs are frequently used for the treatment of behavioural and psychological symptoms of dementia in persons with Alzheimer's disease (AD). Evidence for benefits are limited and concerns have been raised about the safety, especially for the concomitant use of multiple psychotropic drugs. The objective of this study was to investigate prevalence of psychotropic drug and psychotropic polypharmacy (PPP) use and associations with PPP among persons with and without AD, from five years before until four years after AD diagnosis at time points every six months. Data is a part of the nationwide MEDALZ cohort, including all community-dwelling persons who received a clinically verified diagnosis of AD between 2005 and 2011 in Finland (n = 70,719). Register-based data included purchased prescription drugs, comorbidities, and hospital discharge diagnoses. Prevalence and factors associated with PPP were studied with logistic regression. The prevalence of psychotropic drug use, especially use of antipsychotics and antidepressants, increased during the course of AD. The use of ≥ 2 psychotropic drugs increased from 5.9% five years before to 18.3% four years after AD diagnosis. The most frequently used combination was antipsychotics and antidepressants. Predictors for PPP were younger age (< 75 years), female sex and history of psychiatric disease. The use of acetylcholinesterase inhibitors was inversely associated with PPP. The high prevalence of PPP is concerning because of possible higher risks for adverse effects and events.

Abstract
Background and Purpose There is conflicting evidence in the literature on the association between benzodiazepines (BDZs) and the risk of dementia. This meta-analysis aimed to determine the relationship between the long-term usage of BDZs and the risk of dementia. Methods The PubMed and Embase databases were systematically searched for relevant publications up to September 2017. The literature search focused on observational studies that analyzed the relationship between the long-term use of BDZs and the risk of dementia. Pooled rate ratios (RRs) with 95% confidence interval (CI) were assessed using a random-effects model. The robustness of the results was checked by performing subgroup and sensitivity analyses. Results Ten studies were included: six case–control and four cohort studies. The pooled RR for developing dementia was 1.51 (95% CI=1.17–1.95, p=0.002) in patients taking BDZ. The risk of dementia was higher in patients taking BDZs with a longer half-life (RR=1.16, 95% CI=0.95–1.41, p=0.150) and for a longer time (RR=1.21, 95% CI=1.04–1.40, p=0.016). Conclusions This meta-analysis that pooled ten studies has shown that BDZ significantly increases the risk of dementia in the elderly population. The risk is higher in patients taking BDZ with a longer half-life (>20 hours) and for a longer duration (>3 years).

Abstract
There has been a growing interest in the relationship between sedative-hypnotics use and the risk of Alzheimer's dementia (AD) risk. This study aimed to evaluate the risk of AD associated with the use of sedative-hypnotics. A retrospective cohort study was conducted with randomly selected 5% samples from ≥50 years old beneficiaries of National Health Insurance Service (NHIS) of Korea from January 2002 to December 2015. The exposure to sedative-hypnotics was defined when prescribed over 30 defined daily dose (DDD) after January 2004 and it was categorized by prescribed dosage, types and half-lives of benzodiazepines. Time-dependent Cox regression model with a lag period of 5-years was used to evaluate the association between use of sedative-hypnotics and the risk of subsequent AD. Sensitivity analysis was performed for restricting sedative-hypnotics only when prescribed with insomnia. A total of 268,170 subjects were identified and subjects exposed to sedative-hypnotics showed a higher risk of AD (HR: 1.79; 95% CI: 1.72-1.86) than those who were not. There was an increased risk of AD among subjects exposed to benzodiazepines or zolpidem (HR: 1.75; 95% CI: 1.67-1.82) and antidepressants or low-dose antipsychotics (HR: 1.63; 95% CI: 1.42-1.87). The risk of AD was increased regardless of dose of sedative-hypnotics and half-life among benzodiazepines, especially in exposure to more than 360 DDD of sedative-hypnotics (HR: 1.78; 95% CI: 1.60-1.99) and the long-acting benzodiazepine (HR:1.77; 95% CI: 1.65-1.89).

Abstract
OBJECTIVE To assess the association between benzodiazepine and related drug (BZDR) use and risk of Alzheimer's disease (AD) with cumulative consumption and duration of use based models. METHOD A nationwide nested case-control study of all Finnish community-dwelling persons who received clinically verified AD diagnosis in 2005-2011 (N = 70 719) and their matched controls (N = 282 862). AD diagnosis was based on DSM-IV and NINCDS-ADRDA criteria. BZDR purchases were extracted from the Prescription Register since 1995. The association between BZDR use and AD was assessed using conditional logistic regression with 5-year lag time between exposure and outcome. RESULTS Benzodiazepine and related drug use was associated with modestly increased risk of AD (adjusted OR 1.06, 95% CI 1.04-1.08). A dose-response relationship was observed with both cumulative consumption and duration. Adjustment for other psychotropics removed the cumulative dose-response relationship by attenuating the ORs in the highest dose category. CONCLUSION Benzodiazepine and related drug use in general was associated with modestly increased risk of AD. No major differences were observed between different subcategories of BZDRs (i.e. benzodiazepines, Z drugs, short-/medium-acting or long-acting BZDRs). As dose-response relationship abolished after adjustment for other psychotropics, it is possible that the association may partially be due to antidepressants and/or antipsychotics, or concomitant use of these medications.

Abstract
INTRODUCTION This study set out to clarify the differential acute cognitive impact of lorazepam based on varying genetic risk for Alzheimer disease. METHODS Fifty-seven cognitively unimpaired individuals aged 51 to 88, genotyped according to apolipoprotein E (APOE) and translocase of outer mitochondrial membrane (40 homolog) poly-T lengths, completed cognitive testing before, 2.5 and 5 hours after receiving a 1 mg dose of lorazepam. RESULTS Post-lorazepam, there were significant (P<0.05) declines from baseline in memory, psychomotor processing speed, and executive function. At 2.5 hours, the magnitude of this lorazepam-induced cognitive change was significantly greater in the APOE3/4 group than in the APOE3/3 group for tests of working memory and visuospatial memory/executive function. At 5 hours postchallenge, verbal memory and working memory deficits persisted in the APOE3/4 group compared with the APOE3/3 group. At 5 hours after lorazepam challenge, as compared with the very long/very long group, the short/short group performed slightly worse on a test of working memory (P<0.05), but no other differences were observed among translocase of the outer mitochondrial membrane 40 homolog poly-T variant groups. DISCUSSION The lorazepam challenge may be unmasking presymptomatic cognitive dysfunction associated with APOE4 carriage.

Abstract
OBJECTIVES To investigate the association between daily sleep duration and risk of dementia and death in a Japanese elderly population. DESIGN Prospective cohort study. SETTING The Hisayama Study, Japan. PARTICIPANTS Community-dwelling Japanese individuals aged 60 and older without dementia. MEASUREMENTS Self-reported daily sleep duration was grouped into 5 categories (<5.0, 5.0-6.9, 7.0-7.9, 8.0-9.9, ≥10.0 hours). The association between daily sleep duration and risk of dementia and death was determined using a Cox proportional hazards models. RESULTS During follow-up, 294 participants developed dementia, and 282 died. Age- and sex-adjusted incidence rates of dementia and all-cause mortality were significantly greater in subjects with daily sleep duration of less than 5.0 hours and 10.0 hours and more than in those with daily sleep duration of 5.0 to 6.9 hours. These associations remained unchanged after adjustment for potential confounding factors (<5.0 hours: hazard ratio (HR)=2.64, 95% confidence interval (CI)=1.38-5.05 for dementia; HR=2.29, 95% CI=1.15-4.56 for death; ≥10.0 hours: HR=2.23, 95% CI=1.42-3.49 for dementia; HR=1.67, 95% CI=1.07-2.60 for death). Similar U-shaped associations were observed for Alzheimer's disease and vascular dementia. With regard to the influence of hypnotic use on risk of dementia and death, subjects who used hypnotics and had any sleep duration had a risk of dementia that was 1.66 times as great and a risk of death that was 1.83 times as great as those who did not use hypnotics and had a daily sleep duration of 5.0 to 6.9 hours. CONCLUSION Short and long daily sleep duration and hypnotic use are risk factors for dementia and death in Japanese elderly adults.

Abstract
BACKGROUND Benzodiazepine use is highly prevalent in elderly and late middle-aged populations and may be associated with an increased risk of dementia. Observational studies have suggested that benzodiazepine use may increase the risk of dementia, however there have been significant concerns regarding protopathic bias in these studies, precluding conclusive findings. OBJECTIVE The aim of our study was to investigate the risk of dementia associated with the use of benzodiazepines in elderly patients, after controlling for protopathic bias. METHODS We identified observational studies with more than 50 cases, adequate assessment of benzodiazepine exposure, and reliable dementia diagnosis ascertainment, from the MEDLINE, PubMed, EMBASE, CINAHL, LILACS and CENTRAL electronic databases through to 5 June 2018, with no language limits. The association of any current or former use of short- or long-acting benzodiazepines with incident dementia was analysed. A subgroup analysis was performed by the introduction of lag time to assess the effect of protopathic bias. We also performed analyses considering the effect of higher benzodiazepine cumulative doses and adjustment for psychiatric covariates. Study quality was investigated using the Newcastle-Ottawa Scale. RESULTS We identified 15 studies reported in 14 articles, involving 159,090 cases. Ever use of benzodiazepines was associated with a significantly increased risk of dementia [odds ratio (OR) 1.39, 95% confidence interval (CI) 1.21-1.59]. Those studies that implemented the longest lag times of ≥ 5 years, and hence most likely to overcome protopathic bias, found a risk estimate that was marginally attenuated, but still significant (OR 1.30, 95% CI 1.14-1.48). Long-acting benzodiazepines were associated with a marginally higher magnitude risk (OR 1.21, 95% CI 0.99-1.49) than short-acting benzodiazepines (OR 1.13, 95% CI 1.02-1.26), although the former failed to reach statistical significance (p = 0.059). CONCLUSIONS Our findings indicate that the association between benzodiazepine use and dementia incidence is not purely an artefact due to protopathic bias. Reduction of inappropriate benzodiazepine prescription is likely to attenuate dementia risk.

Abstract
INTRODUCTION Generalized anxiety disorder (GAD) is a common form of anxiety disorder. Selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), and benzodiazepines (BZs) are the most commonly prescribed medications for GAD, but little is known about the relative efficacy of these pharmacological treatments. Areas covered: This study provides a meta-analytic review of the efficacy of these medications in the treatment of adults with GAD. A comprehensive literature search yielded 54 articles reporting 56 unique studies with 12,655 participants treated with either pill placebo (6,191 participants), SSRIs (16 trials, 2,712 participants), SNRIs (17 trials, 2,603 participants), or BZs (23 trials, 1,149 participants). The overall combined effect size was modest to moderate (Hedges' g = 0.37, p < 0.0001). Effect sizes decreased significantly over time. SSRIs (Hedges' g = 0.33) and SNRIs (Hedges' g = 0.36) demonstrated significantly lower effect sizes than BZs (Hedges' g = 0.50). These findings were not due to differences in treatment length or publication year. Expert opinion: The results of this study suggest that the most common forms of pharmacotherapy for adult GAD are moderately effective, with BZs being the most effective drug.
