Common psychiatric problems in cognitively impaired older patients: causes and management

Examining Depression Symptoms With/Without Coexisting Anxiety Symptoms in Community-Dwelling Persons With Dementia

Depression and anxiety are common in persons with dementia (PWD) and associated with poor outcomes. We explored frequency, pharmacologic management and mental health service use in PWD and depression symptoms with/without coexisting anxiety symptoms. The sample comprised 160 community-dwelling PWD in a trial to prevent development of aggression. Baseline data on depression and anxiety symptoms, psychotropic medications and mental health service use were examined. Regarding participants, 65 (41%) lacked clinically significant depression or anxiety symptoms, 45 (28%) had depression symptoms, 43 (27%) had depression and anxiety symptoms, and 7 (4%) had anxiety symptoms. Comorbid anxiety was associated with more severe depression symptoms. One third with depression symptoms and one half with depression and anxiety symptoms were taking an antidepressant. Mental health service use was very low, regardless of depression symptom severity or coexisting anxiety. Research needs to evaluate therapies for depressed PWD, but treatment of those with comorbid anxiety and depression is more urgent.

Psychotropic medication use patterns in home-based primary care: A scoping review

Introduction

Up to a third of patients seen by home-based primary care (HBPC) providers suffer from mental health problems. These conditions tend to be underrecognized and undertreated for patients receiving HBPC. The purpose of this scoping review is to evaluate current psychotropic use patterns for patients receiving HBPC services.

Methods

The following databases were searched for articles reporting on studies conducted in HBPC settings that identified patterns of psychotropic medication prescription and use: Ovid/MEDLINE, Cochrane Library, Embase, Scopus, Web of Science, CINAHL, and PsycInfo. Studies that only reported on patients in hospice, rehabilitation, or long-term care facilities were excluded as were drug trials, opinion pieces, case studies, case series, meeting abstracts, and other reviews.

Results

Of 4542 articles initially identified, 74 were selected for full text screening. Of these, only 2 met full criteria and were included in the data extraction and analysis. In 1 study, 41.7% patients enrolled were prescribed an antidepressant, 21.5% were prescribed an antipsychotic (12.7% prescribed both), and 5% to 7% of patients were prescribed benzodiazepines/hypnotics. In the other study, 9% of patients were prescribed an antipsychotic, and 7% were prescribed a benzodiazepine.

Discussion

There are extremely limited data on psychotropic prescribing patterns in HBPC in published studies. Because a significant number of HBPC patients suffer from mental health conditions in addition to other chronic illnesses, treatment can be complex. More studies are needed on current psychotropic prescribing trends to help determine what type of interventions are needed to promote patient safety in this setting.

Longitudinal Effects of Activities, Social Environment, and Psychotropic Medication Use on Behavioral Symptoms of Individuals With Alzheimer's Disease in Nursing Homes

A secondary data analysis of 25,560 minutes of structured clinical observations from a longitudinal study examined the impact of time-varying background factors, social environment, and psychotropic medication use on behavioral symptoms of nursing home residents with Alzheimer's disease (AD). Data were collected at baseline (N = 177), 12 months (N = 138), and 24 months (N = 111). Mixed-effects regression modeling showed that at 24 months: (a) higher cognitive and physical function and having a private bedroom/bathroom had the most positive influence on resident positive behaviors; (b) use of antipsychotic medications and solitary activities had the most negative influence on resident positive behaviors; (c) higher cognitive function significantly decreased negative behaviors; and (d) care-related activities and total number of psychotropic medications significantly increased negative behaviors. The current study describes risk factors for behavioral disturbances and the impact of activities, social environment, and psychotropic medications on behavioral outcomes in nursing home residents with AD.

Comedication and Treatment Length in Users of Acetylcholinesterase Inhibitors

BACKGROUND/AIMS

Reduced clinical effect on cognitive decline in dementia by acetylcholinesterase inhibitors (AChEIs) may be due to concurrent use of drugs with anticholinergic properties. The aim was to analyze the incidence of AChEI use and comedication with drugs with anticholinergic properties and other potential unfavorable effects.

METHODS

A prospective study applying drug use data from the Norwegian Prescription Database. Anticholinergic Drug Scale (ADS) scores were used as a measure of overall anticholinergic burden.

RESULTS

Patients with high ADS scores were more frequently discontinuing treatment early. Coprescribing of antipsychotics was strongly associated with early discontinuation of AChEI treatment.

CONCLUSION

Coprescribing with potentially unfavorable medications was common. A high ADS score was associated with early discontinuation of treatment.

Late-life psychosis: diagnosis and treatment

Psychosis is one of the most common conditions in later life with a lifetime risk of 23 %. Despite its high prevalence, late-onset psychosis remains a diagnostic and treatment dilemma. There are no reliable pathognomonic signs to distinguish primary or secondary psychosis. Primary psychosis is a diagnosis of exclusion and the clinician must rule out secondary causes. Approximately 60 % of older patients with newly incident psychosis have a secondary psychosis. In this article, we review current, evidence-based diagnostic and treatment approaches for this heterogeneous condition, emphasizing a thorough evaluation for the "six d's" of late-life psychosis (delirium, disease, drugs dementia, depression, delusions). Treatment is geared towards the specific cause of psychosis and tailored based on comorbid conditions. Frequently, environmental and psychosocial interventions are first-line treatments with the judicious use of pharmacotherapy as needed. There is an enormous gap between the prevalence of psychotic disorders in older adults and the availability of evidence-based treatment. The dramatic growth in the elderly population over the first half of this century creates a compelling need to address this gap.
