Abstract
BACKGROUNG The early identification of cognitive disorder is a primary scope, because it could reduce the rate of severe cognitive impairment and thus contribute to reduce healthcare costs in the next future. AIMS The present paper aimed to build a virtuous diagnostic path of cognitive impairment, highlighting all the professionalism that can serve this purpose. METHODS The Delphi method was used by the experts, who reviewed the information available during each meeting related to the following topics: early diagnosis of cognitive impairment, definition of Mild Cognitive Impairment, unmet needs in post-stroke patients, critical decision-making nodes in complex patients, risk factors, neuropsychological, imaging diagnosis, blood tests, the criteria for differential diagnosis and the possible treatments. RESULTS The discussion panels analyzed and discussed the available evidences on these topics and the related items. At each meeting, the activities aimed at the creation of a diagnostic-welfare flow chart derived from the proposal of the board and the suggestions of the respondents. Subsequently, the conclusions of each panel were written, and the study group reviewed them until a global consensus was reached. Once this process was completed, the preparation of the final document was carried out. CONCLUSIONS Eventually, we built an algorithm for the early diagnosis and treatment, the risk factors, with the possible differences among the different kinds of dementia.

Comparative Outcomes of Commonly Used Off-Label Atypical Antipsychotics in the Treatment of Dementia-Related Psychosis: A Network Meta-analysis. Adv Ther 2022; 39:1993-2008. [PMID: 35247186 PMCID: PMC9056477 DOI: 10.1007/s12325-022-02075-8] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2021] [Accepted: 02/03/2022] [Indexed: 11/01/2022]
Abstract
INTRODUCTION Dementia-related psychosis (DRP) is characterized by hallucinations and delusions, which may increase the debilitating effects of underlying dementia. This network meta-analysis (NMA) evaluated the comparative efficacy, safety, and acceptability of atypical antipsychotics (AAPs) commonly used off label to treat DRP. METHODS We included 22 eligible studies from a systematic literature review of AAPs (quetiapine, risperidone, olanzapine, aripiprazole, and brexpiprazole) used off label to treat DRP. Study outcomes were: (1) efficacy-neuropsychiatric inventory-nursing home (NPI-NH psychosis subscale), (2) safety-mortality, cerebrovascular events (CVAEs), and others (somnolence, falls, fractures, injuries, etc.), and (3) acceptability-discontinuations due to all causes, lack of efficacy, and adverse events (AEs). We used random-effects modeling to estimate pooled standardized mean differences (SMDs) for NPI-NH psychosis subscale scores and odds ratios (OR) for other dichotomous outcomes, with their respective 95% confidence intervals (CIs). RESULTS Compared with placebo, aripiprazole (SMD - 0.12; 95% CI - 0.31, 0.06), and olanzapine (SMD - 0.17; 95% CI - 0.04; 0.02) demonstrated small, non-significant numerical improvements in NPI-NH psychosis scores (5 studies; n = 1891), while quetiapine (SMD 0.04; 95% CI - 0.23, 0.32) did not improve symptoms. The odds of mortality (15 studies, n = 4989) were higher for aripiprazole (OR 1.58; 95% CI 0.62, 4.04), brexpiprazole (OR 2.22; 95% CI 0.30, 16.56), olanzapine (OR 2.21; 95% CI 0.84, 5.85), quetiapine (OR 1.68; 95% CI 0.70, 4.03), and risperidone (OR 1.63; 95% CI 0.93, 2.85) than for placebo. Risperidone (OR 3.68; 95% CI 1.68, 8.95) and olanzapine (OR 4.47; 95% CI 1.36, 14.69) demonstrated significantly greater odds of CVAEs compared to placebo. Compared with placebo, odds of all-cause discontinuation were significantly lower for aripiprazole (OR 0.71; 95% CI 0.51, 0.98; 20 studies; 5744 patients) and higher for other AAPs. Aripiprazole (OR 0.5; 95% CI 0.31, 0.82) and olanzapine (OR 0.48; 95% CI 0.31, 0.74) had significantly lower odds of discontinuation due to lack of efficacy (OR 12 studies; n = 4382) compared to placebo, while results for quetiapine and risperidone were not significant. Compared with placebo, the odds of discontinuation due to AEs (19 studies, n = 5445) were higher for olanzapine (OR 2.62; 95% CI 1.75, 3.92), brexpiprazole (OR 1.80; 95% CI 0.80, 4.07), quetiapine (OR 1.25; 95% CI 0.82, 1.91), aripiprazole (OR 1.38; 95% CI 0.90, 2.13), and risperidone (OR 1.41; 95% CI 1.02, 1.94). CONCLUSIONS Overall results demonstrate that, compared with placebo, quetiapine is not associated with improvement in psychosis in patients with dementia, while olanzapine and aripiprazole have non-significant small numerical improvements. These off-label AAPs (quetiapine, risperidone, olanzapine, aripiprazole, and brexpiprazole) are associated with greater odds of mortality, CVAEs, and discontinuations due to AEs than placebo. These results underscore the ongoing unmet need for newer pharmacological options with a more favorable benefit-risk profile for the treatment of DRP.

The risk of polypharmacy and potentially inappropriate drugs in residential care dementia patients: tips from the PharE study. Aging Clin Exp Res 2021; 33:1909-1917. [PMID: 33226608 DOI: 10.1007/s40520-020-01719-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2020] [Accepted: 09/16/2020] [Indexed: 02/03/2023]
Abstract
AIMS The aims of the present study, conducted in two regions of Italy, Calabria and Piedmont, were to assess the use of inappropriate drugs according to the Beers Criteria and to study the possible drug-drug interactions. METHODS Data were obtained retrospectively from 972 residential care patients between 2016 and 2018. Mean age was 82.4 ± 8.4 years, with a prevalence of women (64.8%). Activities of daily living, instrumental activities of daily living, Mini-Mental State Examination, Cumulative Illness Rating Scale, Neuropsychiatric Inventory Scale and number and kind of drugs were recorded. A classification of potential inappropriate drugs was made according to the Beers criteria. Data were collected through an Excel file able to gather the main information. In the case of suspected adverse event, Naranjo Scale was applied. The study of possible drug-drug interactions was made by Micromedex 2.0. RESULTS Functional and cognitive impairments, comorbidities and number of drugs were assessed. The bivariate relationship between number of drugs and glomerular filtration rate assessed by CKD-EPI showed that the higher was the number of drugs used, the worst was kidney function assessment (p = 0.0001). The most frequent inappropriate drugs were anticholinergic drugs, tricyclics antidepressants, long-half-life benzodiazepines, antipsychotics and proton pump inhibitors. CONCLUSIONS These data are very interesting and show the need for an accurate choice of drugs in elderly people and for starting a wise deprescribing procedure.

Abstract
Prescription for inappropriate drugs can be dangerous to the elderly due to the increased risk of adverse drug reactions and drug-interactions. In this manuscript, we report the complexity of polypharmacy and the possible harmful consequences in an old person. An 81-year-old man with a clinical history of diabetes, blood hypertension, non-valvular atrial fibrillation, chronic obstructive pulmonary disease, osteoarthritis, anxiety, and depression, was admitted to our attention for cognitive disorders and dementia. Brain magnetic resonance imaging showed parenchymal atrophy with lacunar state involving thalami and internal capsules. Neuropsychological tests revealed cognitive impairment and a depressed mood. History revealed that he was taking 11 different drug severy day with a potential risk of 55 drug-drug interactions. Therefore, risperidone, chlorpromazine, N-demethyl-diazepam, and L-DOPA/carbidopa were gradually discontinued and citicoline (1g/day), cholecalciferol (50,000 IU once a week), and escitalopram (5 mg/day) were started. Furthermore, he started a program of home rehabilitation. During the follow-up, three months later, we recorded an improvement in both mood and cognitive tests, as well as in walking ability. The present case report shows the need for a wise prescription and deprescribing in older people.

Abstract
BACKGROUND A typical antipsychotics for neuropsychiatric symptoms in dementia have been tested in much larger trials than the older conventional drugs. The advantage of larger sample sizes is that negative findings become less likely and the effect estimates more precise. However, as sample sizes increase, the trials also get more expensive and time consuming while exposing more patients to drugs with unknown safety profiles. Moreover, a large sample size might yield a statistically significant effect that is not necessarily clinically relevant. OBJECTIVE To assess (1) the variation in sample size and sample size calculations of antipsychotic trials in dementia, (2) the size of reported treatment effects and related statistical significance, and (3) general study characteristics that might be related to sample size. STUDY DESIGN AND SETTING We performed a meta-epidemiological study of randomized trials that tested antipsychotics for neuropsychiatric symptoms in dementia. The trials compared conventional or atypical antipsychotics with placebo or another antipsychotic. Two reviewers independently extracted sample size, sample size calculations, reported treatment effects with p-values, and general study characteristics (drug type, trial duration, type of funding). We calculated a reference sample size of 83 and 433 per study group for the placebo-controlled and head-to-head trials respectively. RESULTS We identified 33 placebo-controlled trials, and 18 head-to-head trials. Only 14 (42%) and 2 (11%), respectively, reported a sample size calculation. The average sample size per arm was 34 (range 6-179) in placebo-controlled trials testing conventional drugs, 107 (8-237) in such trials testing atypical drugs, and 104 (95-115) in such trials testing both drug types; it was 31 (10-88) in head-to-head trials. Thirteen out of 18 trials with sample sizes larger than required (72%) reported a statistically significant treatment effect, of which two (15%) were clinically relevant. None of the head-to-head trials reported a statistically significant treatment effect, even though some suggested non-inferiority. In placebo-controlled trials of atypical drugs, longer trial duration (>6 weeks) and commercial funding were associated with higher sample size. CONCLUSION Sample size calculations were poorly reported in antipsychotic trials for dementia. Placebo-controlled trials of atypical antipsychotics showed large sample size fallacy while head-to-head trials were massively underpowered.

Abstract
Antipsychotic medications are widely used in the management of behavioral and psychological symptoms of dementia. While nonpharmacological interventions should be the first-line treatment for behavioral symptoms of dementia, these are often unfeasible and/or ineffective. Conventional and atypical antipsychotic agents appear to have modest to moderate clinical efficacy in the treatment of these symptoms, though it is unclear which individual agents are most effective. No conclusive evidence exists that any available alternative medications are safer and more effective than antipsychotics. A number of studies have shown an increased risk of mortality associated with antipsychotics in patients with behavioral symptoms of dementia, though the observed risk increase may be partially confounded by illness severity and/or preexisting health determinants. The mechanisms of increased mortality risk are not fully established, but are likely to involve cardiovascular events. It is probable, though not certain, that conventional antipsychotics are associated with a greater number of poor outcomes than atypical antipsychotics. In certain patients with refractory behavioral symptoms, antipsychotics are a viable treatment option. Key considerations for antipsychotic prescribing for this population are published in regulatory guidelines, and include minimization of dosage and duration of treatment, continuous reevaluation of symptoms, and involvement of caregivers.

Abstract
Antipsychotic drugs (APs) are of great benefit in several psychiatric disorders, but they can be associated with various adverse effects, including seizures. To investigate the effects of chronic antipsychotic treatment on seizure susceptibility in genetically epilepsy-prone rats, some APs were administered for 7 weeks, and seizure susceptibility (audiogenic seizures) was evaluated once a week during treatment and for 5 weeks after drug withdrawal. Furthermore, acute and subchronic (5-day treatment) effects were also measured. Rats received haloperidol (0.2-1.0 mg/kg), clozapine (1-5 mg/kg), risperidone (0.03-0.50 mg/kg), quetiapine (2-10 mg/kg), aripriprazole (0.2-1.0 mg/kg), and olanzapine (0.13-0.66 mg/kg), and tested according to treatment duration. Acute administration of APs had no effect on seizures, whereas, after regular treatment, aripiprazole reduced seizure severity; haloperidol had no effects and all other APs increased seizure severity. In chronically treated rats, clozapine showed the most marked proconvulsant effects, followed by risperidone and olanzapine. Quetiapine and haloperidol had only modest effects, and aripiprazole was anticonvulsant. Finally, the proconvulsant effects lasted at least 2-3 weeks after treatment suspension; for aripiprazole, a proconvulsant rebound effect was observed. Taken together, these results indicate and confirm that APs might have the potential to increase the severity of audiogenic seizures but that aripiprazole may exert anticonvulsant effects. The use of APs in patients, particularly in patients with epilepsy, should be monitored for seizure occurrence, including during the time after cessation of therapy. Further studies will determine whether aripiprazole really has a potential as an anticonvulsant drug and might also be clinically relevant for epileptic patients with psychiatric comorbidities.

Abstract
The metabolic side effects of atypical antipsychotics (AAPs) have been widely studied in younger populations, but research investigating these sequelae in the elderly is lacking. This article reviews the available literature examining the use of AAPs in the elderly, evaluating their association with weight gain and changes in blood glucose and lipid parameters. We find a relative paucity of studies in this area; while some data highlight significant, collective changes in metabolic parameters, the majority suggests an apparent low vulnerability to these side effects. We conclude that the risk and clinical implications of unfavorable metabolic changes in the elderly being treated with AAP medications remain largely undetermined, and we caution against drawing firm conclusions based on the available data. The conflicting evidence leaves us recommending that metabolic monitoring be implemented, with regular follow-up as advocated in other populations.

Abstract
In recent years, the use of antipsychotics has been widely debated for reasons concerning their safety in elderly patients affected with dementia. To update the use of antipsychotics in elderly demented people, a MEDLINE search was conducted using the following terms: elderly, conventional and atypical antipsychotics, adverse events, dementia, and behavioral and psychotic symptoms in dementia (BPSD). Owing to the large amounts of studies on antipsychotics, we mostly restricted the field of research to the last 10 years. Conventional antipsychotics have been widely used for BPSD; some studies showed they have an efficacy superior to placebo only at high doses, but they are associated with several and severe adverse effects. Atypical antipsychotics showed an efficacy superior to placebo in randomized studies in BPSD treatment, with a better tolerability profile versus conventional drugs. However, in 2002, trials with risperidone and olanzapine in elderly patients affected with dementia-related psychoses suggested the possible increase in cerebrovascular adverse events. Drug regulatory agencies issued specific recommendations for underlining that treatment of BPSD with atypical antipsychotics is "off-label." Conventional antipsychotics showed the same likelihood to increase the risk of death in the elderly as atypical agents, and they should not replace the atypical agents discontinued by Food and Drug Administration warnings. Before prescribing an antipsychotic drug, the following are factors to be seriously considered: the presence of cardiovascular diseases, QTc interval on electrocardiogram, electrolytic imbalances, familiar history for torsades des pointes, concomitant treatments, and use of drugs able to lengthen QTc. Use of antipsychotics in dementia needs a careful case-by-case assessment, together with the possible drug-drug, drug-disease, and drug-food interactions.

Abstract
BACKGROUND In clinical practice, Second Generation Antipsychotics (SGAs) are often used as first-line treatment for the Behavioral and Psychological Symptoms of Dementia (BPSD) in older adults due to their fewer neurological adverse events and similar effectiveness compared with First Generation Antipsychotics (FGAs). SGAs, however, are associated with more severe metabolic side effects (weight gain, hyperglycemia, diabetes risk, and hyperlipidemia) than FGAs are. In general, older patients, especially those affected by dementia, are at increased risk for malnutrition, and tend to have lower basal metabolism and reduced liver and kidney function. However, little is known about the metabolic side effects of antipsychotic drugs in this population. METHODS A comprehensive review of the literature published between January 1996 and December 2012 investigating the metabolic side effects related to FGAs and SGAs use in old patients affected by dementia. RESULTS Antipsychotic drugs currently used to treat BPSD in subjects with mild to moderate dementia are associated with weight gain. Currently, there are insufficient data to support a causal relationship between the use of FGAs and SGAs and changes in glucose homeostasis or lipid metabolism in older persons affected by severe dementia (MMSE <14). CONCLUSION A possible association between antipsychotic drugs use and weight gain might exist, in particular in subjects with mild to moderate dementia whereas no significant effects are demonstrated regarding glucose homeostasis and lipid metabolism. The antipsychotic drugs potential for causing metabolic abnormalities in older patients requires further specifically designed studies. Clinicians must be aware of this possibility even if the shorter periods of treatment administered in late-life might not be as harmful as it is in younger individuals.

Abstract
Background Antipsychotic drugs are widely used for the treatment of Behavioral and Psychological Symptoms of Dementia (BPSD), despite their limited efficacy and concerns about safety. The aim of this study was to describe antipsychotic drug therapy among people with dementia living in specialized care units in northern Sweden. Methods This study was conducted in 40 specialized care units in northern Sweden, with a total study population of 344 people with dementia. The study population was described in regard to antipsychotic drug use, ADL function, cognitive function and BPSD, using the Multi-Dimensional Dementia Assessment Scale (MDDAS). These data were collected at baseline and six months later. Detailed data about antipsychotic prescribing were collected from prescription records. Results This study showed that 132 persons (38%) in the study population used antipsychotic drugs at the start of the study. Of these, 52/132 (39%) had prescriptions that followed national guidelines with regard to dose and substance. After six months, there were 111 of 132 persons left because of deaths and dropouts. Of these 111 people, 80 (72%) were still being treated with antipsychotics, 63/111 (57%) with the same dose. People who exhibited aggressive behavior (OR: 1.980, CI: 1.515-2.588), or passiveness (OR: 1.548, CI: 1.150-2.083), or had mild cognitive impairment (OR: 2.284 CI: 1.046-4.988), were at increased risk of being prescribed antipsychotics. Conclusion The prevalence of antipsychotic drug use among people with dementia living in specialized care units was high and inappropriate long-term use of antipsychotic drugs was common.

Abstract
BACKGROUND Behavioural problems are common in people with intellectual disability (ID) and are often treated with antipsychotics. AIM To establish the frequency and characteristics of people with ID included in randomised controlled trials (RCTs) on antipsychotic treatment for behavioural problems, and to investigate the quality of these RCTs. METHODS A literature search in EMBASE, PubMed and Cochrane was performed and reviewed. RESULTS People with ID participated in 27 of the 100 included RCTs. The RCTs were of good quality but smaller compared with trials in patients with dementia or schizophrenia (average sample sizes = 55, 124 and 374). In 13/27 trials no clear definition of ID was given. Over 25 different outcome measures were used to assess behavioural problems. CONCLUSIONS Studies in which people with ID are included are of a sufficient quality, but of a small size. The heterogeneity in the characteristics of the ID population included as well as in the applied assessment instruments makes performing meta-analyses unfeasible.

Abstract
RATIONALE Antipsychotic drugs are widely used as a first-line pharmacological approach to treat dementia-related psychiatric symptoms. However, in this population of patients, such drugs have been associated with severe safety concerns. Hence, the aim of this review is to asses systematically the efficacy of second-generation antipsychotics (SGAs) in treating dementia-related neuropsychiatric symptoms in order to establish if the potential clinical benefits of such treatment outweigh the hypothesised risks related to pharmacological intervention. METHODS The Cochrane Library, MEDLINE, EMBASE and PsycINFO were searched (from 1980 to June 22, 2010) using terms for included drugs (aripiprazole, clozapine, olanzapine, quetiapine, risperidone, ziprasidone, SGAs) and indications (elderly, dementia, Alzheimer's disease). Electronic database search were supplemented with hand search of references lists of electronically identified articles. Peer-reviewed, randomised, controlled trials published in English and investigating the efficacy of SGAs in patients with different forms of dementia were included in the review process. Information was drawn from the 30 articles that met the inclusion criteria. RESULTS Nearly all reviewed studies suffer from methodological limitations too severe to draw definitive conclusions that may inform the decision-making process. Moreover, studies conducted with similar methodological design show conflicting efficacy results. CONCLUSIONS Because of their undemonstrated effectiveness, SGAs should be avoided in patients with dementia complicated by psychotic and/or behavioural symptoms. Hence, further researches are urgently needed to identify useful pharmacological strategies that can be used to improve the clinical condition of such patients and to reduce burden to caregivers when behavioural interventions are ineffective.

Abstract
BACKGROUND Clozapine was the first atypical 'broad spectrum' antipsychotic drug to be marketed and the first agent approved for the treatment of schizophrenia refractory to other medications. It is also effective for the treatment of aggressive behaviour in schizophrenic and demented patients and in the management of psychosis and aggression in Parkinson's disease and Lewy body dementia. OBJECTIVE The aim of this review is to study the safety of clozapine for use in elderly patients. METHODS An extensive Medline search was made. Some studies that were referenced in reports from our pharmacovigilance centre and from regulatory agencies such as the FDA, EMEA and WHO were included. CONCLUSIONS Clozapine treatment in the elderly requires a careful geriatric assessment. However, its use is strongly limited by the possibility of onset of severe adverse effects such as potentially fatal agranulocytosis, myocarditis and others such as seizures, weight gain and metabolic adverse effects.

Abstract
BACKGROUND Vocally disruptive behavior (VDB) in the elderly is a common condition, especially in people with dementia, but difficult to treat. It may occur in as many as 40% of nursing home residents. This study is a review of the existing literature on this condition. METHOD The literature review was conducted using PubMed (particularly Medline and the Cochrane database) and reference lists from relevant publications in English, French, and German. RESULTS Most studies are small and no conclusive prevalence data are available. Many biological and psychosocial treatments have been advocated, but most studies are little more than anecdotal case reports. It is evident that VDB can have deleterious consequences on others and the patients themselves, although no studies specifically examine the range or the pervasiveness of VDB. Etiopathogenic research on VDB is still in its infancy. CONCLUSIONS Most aspects surrounding VDB are insufficiently understood. The heterogeneity and multiple contributive factors regarding VDB suggest quite convincingly that a panoply of different interventions tailored to the individual's needs will be required to overcome VDB and the suffering related to it.

Abstract
The objectives of this retrospective, naturalistic study were to provide preliminary data on the effects of 6 months treatment with risperidone, olanzapine and quetiapine on behavioral disturbances, within a sample of outpatients with mild to moderate Alzheimer's disease, and on predictors of response. Between July 2005 and December 2005, data were collected from 58 consecutive outpatients with a DSM-IV-TR diagnosis of Alzheimer's disease with behavioral disturbances, who received a 6-month treatment with risperidone, olanzapine or quetiapine. Primary outcome measures were Neuropsychiatric Inventory (NPI) total score and its items forming the basic core of behavioral disturbances in Alzheimer's disease: delusions, hallucinations and agitation/aggressiveness. Secondary outcome measures were Mini-Mental State Examination (MMSE), Activities of Daily Living, Instrumental Activities of Daily Living and Clinical Insight Rating scale. Correlations between baseline MMSE score and improvements in behavioral disturbances were investigated. At 6 months mean NPI total score had fallen 43.5% in the risperidone group, 45.6% in the olanzapine group and 33.3% in the quetiapine group, with no significant between-group differences. Global cognitive function showed no significant change from baseline to end-point. Incidence of adverse events was low. A significant correlation was found between MMSE score and NPI total score and NPI item agitation decreases. Risperidone, olanzapine and quetiapine produced significant improvements in behavioral disturbances and were well tolerated. No significant differences emerged among treatments. The preliminary results also suggest that baseline cognitive function might influence treatment response.

Abstract
Risperidone has been shown to be a safe and effective atypical antipsychotic agent. It was initially approved for the treatment of schizophrenia, and now, in many countries, is used to treat other conditions, including bipolar disorder, dementia and behavior problems in a range of age groups. Yet, frequent off-label use by clinicians to treat other mood and anxiety disorders and behavioral disorders is common and requires an examination of the risks and benefits in such populations. A review of the literature provides varying levels of evidence supporting its use in a range of depressive and anxiety disorders, and in special populations, including children and the elderly. Most reports are based on short-term studies and include its use both as monotherapy and as an augmenting agent to other psychotropics, and in a range of doses. Further randomized controlled trials are needed to confirm the efficacy and tolerability of risperidone, both short- and long-term, in many of these conditions. The published evidence is summarized, with recommendations and suggestions for its use.

Abstract
The behavioral and psychological symptoms of dementia (BPSD), such as psychosis, agitation, or aggression have a considerable negative impact on the quality of life of both patients and their caregivers. Multiple studies have demonstrated that atypical antipsychotics are efficacious in the treatment of the aggressive and psychotic symptom clusters, and here we review their use in this indication. Because of the safety concerns associated with the use of atypical antipsychotics in this population, these drugs must be used judiciously. For patients with severe BPSD such as psychosis, agitation, or aggression, for whom there are few options, atypical antipsychotics, particularly risperidone and olanzapine, should be considered.

Abstract
Use of antipsychotic medication is very common in the elderly and often an essential therapy. However, successful treatment in the elderly requires appropriate multidimensional assessment of the patient, knowledge of possible multiple co-morbidities, and awareness of the complexities of polypharmacy, age-dependent changes in pharmacokinetics and pharmacodynamics, and drug-drug interactions in this age group. Antipsychotics are known to have a number of adverse effects. New antipsychotics, such as amisulpride, clozapine, olanzapine, risperidone, quetiapine, ziprasidone, zotepine and aripiprazole, may interact with both dopamine and serotonin receptors. However, compared with conventional antipsychotics, they are less likely to cause extrapyramidal symptoms and are better tolerated in the elderly. At the same time, consistent differences between atypical antipsychotics have been demonstrated. Use of clozapine, for example, is limited by the risk of agranulocytosis, whereas this is not a disadvantage of olanzapine, risperidone, quetiapine and, more recently, ziprasidone, which are being widely used with good results in schizophrenia. However, use of the latter agents to treat the behavioural and psychological symptoms of dementia has been restricted because of recent observations of increased cardiovascular events in patients taking risperidone and olanzapine treatment. Nonetheless, careful review of the literature suggests that the available evidence does not support any causal relationship between use of risperidone or olanzapine and cardiovascular events. This article focuses on some of the main adverse effects commonly reported during administration of atypical antipsychotics to elderly patients. Such effects may be partly explained by age-related changes in pharmacokinetics and pharmacodynamics, and partly by the characteristics of the drugs themselves and their different receptor binding profiles.
