Abstract
OBJECTIVES Eating problems frequently occur in people with dementia with Lewy bodies (DLB), but few studies have investigated the clinical background of this phenomenon. This study examined the relationship between eating problems and various symptoms of DLB and the relation between the treatment needs for DLB people with eating problems and the understanding of their eating problems by caregivers and physicians. DESIGN, MEASUREMENTS, AND PARTICIPANTS This was a subanalysis of a cross-sectional, questionnaire-based survey study. Two hundred sixty-one subjects with DLB were divided into subjects with or without eating problems. Logistic or linear regression analysis was used to investigate the factors influencing eating problems. The treatment needs of DLB people for their eating problems and the understanding of these needs by caregivers and physicians were calculated as participant-caregiver and participant-physician kappa coefficient. RESULTS Of the 261 participants, 27% suffered from eating problems. The presence of eating problems in participants with DLB was related to depression (p = 0.01, OR : 2.19, 95% CI: 1.23-3.91) and apathy (p = 0.01, OR 2.15, 95% CI: 1.20-3.87), while the worsening of eating problems was related to dysphagia (β = 0.24, p = 0.03), apathy (β = 0.23, p = 0.05), and nighttime behavior (β = 0.24, p = 0.04). The participant-physician kappa coefficient for physician understanding of constipation, weight loss, dysphagia, weight gain, and increase in appetite was significantly lower than the corresponding participant-caregiver kappa coefficient (p-value of five symptoms < 0.01). CONCLUSIONS Physicians need to pay more attention to eating problems and their neuropsychiatric background in the long-term support and management of DLB subjects.

Relations of neuropsychiatric symptoms with disease stage, sex, and daily function in mild cognitive impairment and dementia due to Alzheimer's disease: A cross-sectional study. J Psychosom Res 2022; 161:110994. [PMID: 35939891 DOI: 10.1016/j.jpsychores.2022.110994] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Revised: 07/18/2022] [Accepted: 07/19/2022] [Indexed: 11/23/2022]
Abstract
OBJECTIVE To reveal the relations between neuropsychiatric symptoms (NPS), stages of cognitive impairment, sex, and daily function in patients with mild cognitive impairment (MCI) and dementia due to Alzheimer's disease (AD). METHODS A cross-sectional study was conducted from 2014 to 2021 on 1154 patients. Cognitive function, disease severity, NPS, and daily function were evaluated by Mini-mental State Examination, Clinical Dementia Rating Scale, Neuropsychiatric Inventory, and Activities of Daily Living (ADL) respectively. Multivariate logistic regression and linear regression were used to explore the correlations between NPS, disease stage, sex and ADL. RESULTS Affective disturbance displayed the highest prevalence from MCI (52.7%) to severe dementia due to AD (98.2%). Multivariate logistic regression revealed that aberrant motor behavior displayed higher prevalence between groups from MCI to severe dementia due to AD (OR = 4.710, P < 0.001; OR = 3.141, P < 0.001; OR = 2.722, P = 0.002, respectively). In patients with dementia due to AD, hallucination and depression were more prevalent in female (OR = 1.730, P = 0.001; OR = 2.376, P < 0.001, respectively) while male presented higher prevalence in apathy (OR = 0.608, P = 0.002). Linear regression analysis showed that delusion and sleep disturbance were significantly associated with basic ADL across all dementia due to AD stages (delusion: mild: β = 0.113, P = 0.015; moderate: β = 0.159, P = 0.019; severe: β = 0.317, P = 0.018; sleep disturbance: mild: β = 0.164, P < 0.001; moderate: β = 0.167, P = 0.013; severe: β = 0.308, P = 0.025) while anxiety was correlated with instrumental ADL from MCI to moderate dementia due to AD (MCI: β = 0.119, P = 0.006; mild: β = 0.149, P < 0.001; moderate: β = 0.130, P = 0.042). CONCLUSION Different subitems of NPS are strongly correlated with sex, stage of cognitive impairment, and ADL.

Pathogenesis and Personalized Interventions for Pharmacological Treatment-Resistant Neuropsychiatric Symptoms in Alzheimer’s Disease. J Pers Med 2022; 12:jpm12091365.

Abstract
Alzheimer’s disease (AD) is the most common form of dementia, with cognitive impairment as a core symptom. Neuropsychiatric symptoms (NPSs) also occur as non-cognitive symptoms during the disease course, worsening the prognosis. Recent treatment guidelines for NPSs have recommended non-pharmacological treatments as the first line of therapy, followed by pharmacological treatments. However, pharmacological treatment for urgent NPSs can be difficult because of a lack of efficacy or an intolerance, requiring multiple changes in psychotropic prescriptions. One biological factor that might be partly responsible for this difficulty is structural deterioration in elderly people with dementia, which may cause a functional vulnerability affecting the pharmacological response. Other causative factors might include awkward psychosocial interpersonal relations between patients and their caregiver, resulting in distressful vicious circles. Overlapping NPS sub-symptoms can also blur the prioritization of targeted symptoms. Furthermore, consistent neurocognitive reductions cause a primary apathy state and a secondary distorted ideation or perception of present objects, leading to reactions that cannot be treated pharmacologically. The present review defines treatment-resistant NPSs in AD; it may be necessary and helpful for clinicians to discuss the pathogenesis and comprehensive solutions based on three major hypothetical pathophysiological viewpoints: (1) biology, (2) psychosociology, and (3) neurocognition.

Abstract
BACKGROUND We examined differences in the severity of neuropsychiatric symptom (NPS) subsyndromes according to education level among patients with amnestic-mild cognitive impairment (a-MCI) with the aim of identifying patient demographics related to NPS subsyndromes. METHODS Overall, 140 patients with a-MCI were included. We divided the patients into three groups according to their educational level (primary education, middle education, and high education) and compared their demographics. To explore the severity of NPS subsyndromes according to educational level, we used the Neuropsychiatric Inventory (NPI) after adjustments for the Mini-Mental State Examination (MMSE) score. Finally, NPS subsyndromes that were identified as being related to educational level were further explored using a general linear model (GLM). RESULTS Significant differences in several demographics were observed among the three groups. Among the NPS subsyndromes, the scores for aggressiveness were significantly higher in the primary and high education groups than in the middle education group, while the apathy/eating problem scores were significantly higher in the primary education group than in the other groups. The GLM analyses showed that aggressiveness was related to marital status and the Zarit Caregiver Burden Interview (ZBI-J) score, while apathy/eating problems were related to the instrumental activities of daily living (IADL) percentage, the ZBI-J score, and the education level in years. CONCLUSIONS Among NPS subsyndromes, aggressiveness and apathy/eating problems differed according to education level in patients with a-MCI. A GLM analysis suggested that not only education level, but also various other factors should be considered when determining the need for NPS interventions.

Abstract
INTRODUCTION Alzheimer's disease (AD) is the most common form of dementia, and four medications are currently available as symptomatic therapies: three cholinesterase inhibitors (ChEI) and memantine. In June 2021, aducanumab was approved in the United States under an accelerated approval pathway as the first novel putative disease-modifying therapy (p-DMT) targeting the β-amyloid (Aβ) cascade in the brain. The combination of several monotherapies to address the multifactorial pathogenesis of neurodegenerative diseases is an anticipated next step. AREAS COVERED The cholinergic hypothesis and the amyloid cascade hypothesis have been proposed as explanations for the pathogenesis of AD. Given the limited effectiveness of monotherapies based on these hypotheses, approaches using combination therapy are attempting to address the complexity of AD pathogenesis, including putative causative proteins-related neurodegeneration, neurotransmitters, and neuroinflammation, in a comprehensive manner. EXPERT OPINION The efficacy of an initial or add-on combination approach to counteracting neurodegenerative processes and functional deterioration has been investigated. The combination of symptomatic therapies with approved anti-dementia medicines (one ChEI and memantine) has been found to be functionally effective for a moderately severe disease stage. Furthermore, combination strategies involving p-DMTs, symptomatic therapies, and neuro-regeneration may be useful in the future.

Abstract
BACKGROUND Typical and atypical antipsychotics are widely used to treat agitation and psychosis in dementia. However, whether or not they are beneficial is uncertain. Some trials have yielded negative results and effectiveness may be outweighed by harms. OBJECTIVES To assess the efficacy and safety of antipsychotics for the treatment of agitation and psychosis in people with Alzheimer's disease and vascular dementia. SEARCH METHODS We searched ALOIS, the Cochrane Dementia and Cognitive Improvement Group's register, MEDLINE (Ovid Sp), Embase (Ovid SP), PsycINFO (Ovid SP), CINAHL (EBSCOhost), Web of Science Core Collection (ISI Web of Science), LILACS (BIREME), ClinicalTrials.gov and the World Health Organization's meta-register, and the International Clinical Trials Registry Portal on 7 January 2021. Two review authors independently screened the title and abstract of the hits, and two review authors assessed the full text of studies that got through this screening. SELECTION CRITERIA We included randomised, placebo-controlled, parallel-arm trials comparing the effects of antipsychotics and placebo for the treatment of agitation or psychosis in people with dementia due to Alzheimer's disease or vascular dementia, or both, irrespective of age, severity of cognitive impairment, and setting. (The majority of) participants had to have clinically significant agitation (including aggression) or psychosis or both at baseline. We excluded studies about antipsychotics that are no longer available in the USA or EU, or that are used for emergency short-term sedation. We also excluded head-to-head trials and antipsychotic withdrawal trials. DATA COLLECTION AND ANALYSIS The primary outcomes were (1) reduction in agitation or psychosis in participants with agitation or psychosis, respectively at baseline, and (2) the number of participants with adverse events: somnolence, extrapyramidal symptoms, any adverse event, any serious adverse event (SAE), and death. Two review authors independently extracted the necessary data and assessed risk of bias with the Cochrane risk of bias tool. We calculated the pooled effect on agitation and psychosis for typical and atypical antipsychotics separately, and the pooled risk of adverse effects independent of the target symptom (agitation or psychosis). We used RevMan Web for the analyses. MAIN RESULTS The search yielded 8233 separate hits. After assessing the full-text of 35 studies, we included 24 trials that met the eligibility criteria. Six trials tested a typical antipsychotic, four for agitation and two for psychosis. Twenty trials tested an atypical antipsychotic, eight for agitation and 12 for psychosis. Two trials tested both drug types. Seventeen of 26 comparisons were performed in patients with Alzheimer's disease specifically. The other nine comparisons also included patients with vascular dementia or mixed dementia. Together, the studies included 6090 participants (12 to 652 per study). The trials were performed in institutionalised, hospitalised and community-dwelling patients, or a combination of those. For typical antipsychotics (e.g. haloperidol, thiothixene), we are uncertain whether these drugs improve agitation compared with placebo (standardised mean difference (SMD) -0.36, 95% confidence interval (CI) -0.57 to -0.15, 4 studies, n = 361); very low-certainty evidence, but typical antipsychotics may improve psychosis slightly (SMD -0.29, 95% CI -0.55 to -0.03, 2studies, n= 240; low-certainty evidence) compared with placebo. These drugs probably increase the risk of somnolence (risk ratio (RR) 2.62, 95% CI 1.51 to 4.56, 3 studies, n = 466; moderate-certainty evidence) and increase extrapyramidal symptoms (RR 2.26, 95% CI 1.58 to 3.23, 3 studies, n = 467; high-certainty) evidence. There was no evidence regarding the risk of any adverse event. The risks of SAEs (RR 1.32, 95% CI 0.65 to 2.66, 1 study, n = 193) and death (RR 1.46, 95% CI 0.54 to 4.00, 6 studies, n = 578) may be increased slightly, but these estimates were very imprecise, and the certainty was low. The effect estimates for haloperidol from five trials were in line with those of the drug class. Atypical antipsychotics (e.g. risperidone, olanzapine, aripiprazole, quetiapine) probably reduce agitation slightly (SMD -0.21, 95% CI -0.30 to -0.12, 7 studies, n = 1971; moderate-certainty evidence), but probably have a negligible effect on psychosis (SMD -0.11, 95% CI -0.18 to -0.03, 12 studies, n = 3364; moderate-certainty evidence). These drugs increase the risk of somnolence (RR 1.93, 95% CI 1.57 to 2.39, 13 studies, n - 3878; high-certainty evidence) and are probably also associated with slightly increased risk of extrapyramidal symptoms (RR 1.39, 95% CI 1.14 to 1.68, 15 studies, n = 4180; moderate-certainty evidence), serious adverse events (RR 1.32, 95% CI 1.09 to 1.61, 15 studies, n= 4316; moderate-certainty evidence) and death (RR 1.36, 95% CI 0.90 to 2.05, 17 studies, n= 5032; moderate-certainty evidence), although the latter estimate was imprecise. The drugs probably have a negligible effect on the risk of any adverse event (RR 1.05, 95% CI 1.02 to 1.09, 11 studies, n = 2785; moderate-certainty evidence). The findings from seven trials for risperidone were in line with those for the drug class. AUTHORS' CONCLUSIONS There is some evidence that typical antipsychotics might decrease agitation and psychosis slightly in patients with dementia. Atypical antipsychotics reduce agitation in dementia slightly, but their effect on psychosis in dementia is negligible. The apparent effectiveness of the drugs seen in daily practice may be explained by a favourable natural course of the symptoms, as observed in the placebo groups. Both drug classes increase the risk of somnolence and other adverse events. If antipsychotics are considered for sedation in patients with severe and dangerous symptoms, this should be discussed openly with the patient and legal representative.

Abstract
PURPOSE OF REVIEW Parkinson's disease was studied for a long time from the prism of a motor impairment. Recent advances have outlined the importance of cognitive and neuropsychiatric symptoms (NPS) in the PD equation. This review concentrates on the present possibilities of using neuroimaging techniques in order to quantify the cognitive performance and NPS in PD patients. RECENT FINDINGS Mild cognitive impairment as well as many NPS have been acknowledged as important criteria for assessing the quality of life in patients with Parkinson's disease and have been shown as potential factors in predicting further evolution of PD from a clinical perspective. Some NPS strongly influence cognition (depression, REM sleep behavior disorder), while others are less specifically associated with it (impulse control disorders). Neuroimaging techniques reported specific structural, functional, and metabolic brain changes that might be specific for each NPS type. Recent neuroimaging advances report a strong interrelation between NPS and cognitive performance in PD. A special place for consideration is given to REM sleep behavior disorder, depression, and hallucinations. Nevertheless, some studies report distinct results, outlining that the neuroimaging acquisition and analysis techniques still have limitations and also likely represent the complexity of the manifestation of NPS in PD.

Abstract
Feeding and nutrition follow the growth trajectory of the course of life. The profound physiological changes that human body experiences during ageing affect separate aspects of food intake, from tastant perception to satiety. Concurrent morbidities, such as neurodegeneration, as seen in dementia, and metabolic syndrome, may further shape nutritional behaviours, status and adequacy. In an effort to fill the gap between the exhausting basic research and the actual needs of professionals caring for the exponentially expanding ageing population, the current review addresses major factors relevant to appetite and eating disturbances. Does age alter the perception of food modalities? Is food generally still perceived as alluring and delicious with age? Is there an interplay between ageing, cognitive decline, and malnutrition? What tools can we adopt for proper and timely monitoring? Finally, what anatomical and pathophysiological evidence exists to support a hypothesis of central regulation of metabolic perturbations in normal and accelerated cognitive impairment, and how can we benefit from it in health practice?

Abstract
Behavioral and psychological symptoms represent common complications in patients with different types of dementia. Predominantly, they comprise psychosis, agitation and mood disorders, disinhibited behavior, impairment of the sleep and wakefulness rhythm, wandering, perseveration, pathological collecting, or shouting. Their appearance is related to more rapid progression of the disease, earlier institutionalization, use of physical restraints, and higher risk of mortality. Consequently, appearance of behavioral and psychological symptoms of dementia leads to higher costs of care provided and greater distress for caregivers. Clinical guidelines recommend nonpharmacological approaches as the first choice in the treatment of behavioral and psychological symptoms. Pharmacological therapy should be initiated only if the symptoms were not the result of somatic causes, did not respond to nonpharmacological interventions, or were not caused by the prior medication. Acetylcholinesterase inhibitors, memantine, antipsychotic drugs, antidepressants, mood stabilizers, and benzodiazepines are used. This review summarizes the current findings about the efficacy and safety of the treatment of the neuropsychiatric symptoms in dementias with psychopharmaceuticals. Recommendations for treatment with antipsychotics for this indication are described in detail as this drug group is prescribed most often and, at the same time, is related to the highest risk of adverse effects and increased mortality.

Abstract
A recent classification analysis of neuropsychiatric symptoms in patients with Alzheimer's disease (AD) revealed a distinct cluster with apathy and eating problems including anorexia that exhibits frailty. The apathy and frailty are risk factors in the disease progresses. However, there is currently no effective drug for treating both anorexia and apathy in AD. Here, we conducted an open-label pilot study to determine whether ninjin'yoeito (NYT, TJ-108), a multicomponent drug, is effective for improving anorexia and apathy in patients with AD, and consequently their cognitive function. Trials were conducted at three sites in Japan. Twenty patients [4 men and 16 women, average age = 82.6±7.7 (mean±SD) years old], including 19 AD and 1 mixed dementia with anorexia/apathy, were examined. NYT (6-9 g/day) was administered for 12 weeks. The changes in scores for "anorexia" using the Neuropsychiatric Inventory (NPI) subcategory for eating disturbance (primary outcome measure), NPI including "apathy", the vitality index, Mini-Mental State Examination (MMSE), and physical and blood nutrition indices were evaluated at baseline (week 0), and weeks 4, 8 and 12. After week 4, significant improvements were observed in the scores for "anorexia" and "apathy" by NPI and meal ingestion amount. Vitality index and MMSE score were significantly improved by week 12. We propose that NYT, a multicomponent drug with several effects including dopamine modulation, is a new-type dementia therapeutic agent with low risk of adverse reactions that can improve simultaneously anorexia/apathy, as well as cognitive dysfunction in frail AD patients.

Psychosocial or clinico-demographic factors related to neuropsychiatric symptoms in patients with Alzheimer's disease needing interventional treatment: analysis of the CATIE-AD study.

Abstract
OBJECTIVE This study sought to determine psychosocial and clinico-demographic factors related to each symptomatic cluster (i.e., aggressiveness, psychosis, apathy/eating problems, and emotion/disinhibition) of neuropsychiatric symptoms (NPSs) in patients with Alzheimer's disease (AD) needing interventional treatment against their agitation or psychotic symptoms. These clusters were classified from 12 Neuropsychiatric Inventory (NPI) subscores in our previous study using the Clinical Antipsychotic Trials of Intervention Effectiveness-Alzheimer's Disease (CATIE-AD) dataset. METHODS Based on clinical data from 421 AD outpatients with agitation or psychotic symptoms needed interventional treatment enrolled in the CATIE-AD, we conducted logistic regression analyses to examine the relationships between each symptomatic cluster and three psychosocial (marital status, residence, and caregivers' burden) and nine clinico-demographic (age, gender, education year, general cognition, activity of daily living [ADL], general medical health, race, and intake of anti-dementia drugs or psychotropics) factors. RESULTS While no factor contributed to aggressiveness, psychosis was associated with several clinico-demographic factors: female gender, non-Caucasian race, and lower cognitive function. Apathy/eating problems was associated with more severe caregiver burden, living in one's own home, lower ADL level, and male gender, while emotion/disinhibition was predicted by more severe caregiver burden, lower education level, not-married status, and younger age. CONCLUSIONS Among the four NPS clusters, apathy/eating problems and emotion/disinhibition were associated with psychosocial as well as clinico-demographic factors in AD patients with psychotic symptoms or agitation needed interventional treatment.

Measurement of agitation and aggression in adult and aged neuropsychiatric patients: review of definitions and frequently used measurement scales. CNS Spectr 2017; 22:407-414. [PMID: 28179043 DOI: 10.1017/s1092852917000050] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/07/2022]
Abstract
Agitation and aggression in adult psychiatric patients with psychoses and in persons with dementia increase the burden of disease and frequently cause hospitalization. The implementation of currently available management strategies and the development of new ones is hindered by inconsistent terminology that confuses agitation with aggression. This confusion is maintained by many rating scales that fail to distinguish between these two syndromes. We review the frequently used rating scales with a particular focus on their ability to separate agitation from aggression. Agitation and aggression are two different syndromes. For example, reactive aggression is often precipitated by rejection of care and may not be associated with agitation per se. We propose, in treatment studies of behavioral symptoms of dementia and challenging behaviors in psychoses, that outcomes should be evaluated separately for agitation and aggression. This is important for investigation of drug effectiveness since the medication may be effective against one syndrome but not the other. Separate assessments of agitation and aggression should be a general principle of trial design with particular salience for registration studies of medications proposed for approval by the U.S. Food and Drug Administration and other regulatory bodies.

Abstract
Dendrite ramification affects synaptic strength and plays a crucial role in memory. Previous studies revealed a correlation between beta 2-adrenergic receptor dysfunction and Alzheimer's disease (AD), although the mechanism involved is still poorly understood. The current study investigated the potential effect of the selective β2-adrenergic receptor antagonist, ICI 118551 (ICI), on Aβ deposits and AD-related cognitive impairment. Morris water maze test results demonstrated that the performance of AD-transgenic (TG) mice treated with ICI (AD-TG/ICI) was significantly poorer compared with NaCl-treated AD-TG mice (AD-TG/NaCl), suggesting that β2-adrenergic receptor blockage by ICI might reduce the learning and memory abilities of mice. Golgi staining and immunohistochemical staining revealed that blockage of the β2-adrenergic receptor by ICI treatment decreased the number of dendritic branches, and ICI treatment in AD-TG mice decreased the expression of hippocampal synaptophysin and synapsin 1. Western blot assay results showed that the blockage of β2-adrenergic receptor increased amyloid-β accumulation by downregulating hippocampal α-secretase activity and increasing the phosphorylation of amyloid precursor protein. These findings suggest that blocking the β2-adrenergic receptor inhibits dendrite ramification of hippocampal neurons in a mouse model of AD.
