The incidence of depression and its risk factors in Dutch nursing homes and residential care homes.
Although it is known that depression is highly prevalent in institutionalized older adults, little is known about its incidence and risk factors in nursing homes and residential care homes. The aim of this study was to investigate and compare the incidence and associated risk factors for depression in Dutch nursing homes and residential care homes. ⋯ The incidence rate for depression in residents of Dutch nursing homes and residential care homes was high and the associated risk factors found may have important implications for staff.

The 1-month prevalence of generalized anxiety disorder according to DSM-IV, DSM-V, and ICD-10 among nondemented 75-year-olds in Gothenburg, Sweden.
To examine the 1-month prevalence of generalized anxiety disorder (GAD) according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), Diagnostic and Statistical Manual of Mental, Fifth Edition (DSM-V), and International Classification of Diseases, Tenth Revision (ICD-10), and the overlap between these criteria, in a population sample of 75-year-olds. We also aimed to examine comorbidity between GAD and other psychiatric diagnoses, such as depression. ⋯ While GAD was common in 75-year-olds, DSM-IV/V and ICD-10 captured different individuals. Current definitions of GAD may comprise two different expressions of the disease. There was greater congruence between GAD in either classification system and depression than between DSM-IV/V GAD and ICD-10 GAD, emphasizing the close link between these entities.

Randomized Controlled Trial Multicenter StudyThe antipsychotic discontinuation in Alzheimer disease trial: clinical rationale and study design.
: Research studies on the effects of discontinuing antipsychotic medications in patients with dementia have not identified specific target symptoms or response to antipsychotics prior to discontinuation. The Antipsychotic Discontinuation in Alzheimer Disease (ADAD) trial addresses these issues in a randomized, double-blind, placebo-controlled, multicenter risperidone treatment and discontinuation trial. In Phase A, AD patients with psychosis or agitation receive open treatment with risperidone for 16 weeks. Responders are randomized, double-blind, to one of three arms in Phase B: 1) continuation risperidone for the next 32 weeks, 2) risperidone for the next 16 weeks followed by placebo for 16 weeks, or 3) placebo for the next 32 weeks. ⋯ : This study will provide clinically relevant data on the likelihood and time to relapse, and predictors of relapse, in patients switched from risperidone to placebo after response to risperidone treatment. Given the warnings about antipsychotic use in patients with dementia, studies of this type are essential to determine the optimal duration of treatment that confers the greatest benefit to risk ratio and to improve evidence-based treatment strategies.

Undetected cognitive impairment and decision-making capacity in patients receiving hospice care.
: Cognitive dysfunction is common in patients with advanced, life-threatening illness and can be attributed to a variety of factors (e.g., advanced age, opiate medication). Such dysfunction likely affects decisional capacity, which is a crucial consideration as the end-of-life approaches and patients face multiple choices regarding treatment, family, and estate planning. This study examined the prevalence of cognitive impairment and its impact on decision-making abilities among hospice patients with neither a chart diagnosis of a cognitive disorder nor clinically apparent cognitive impairment (e.g., delirium, unresponsiveness). ⋯ : Despite an absence of documented or clinically obvious impairment, more than half of the sample had significant cognitive impairments. Assessment of cognition in hospice patients is warranted, including assessment of verbal abilities that may interfere with understanding or reasoning related to treatment decisions. Identification of patients at risk for impaired cognition and decision making may lead to effective interventions to improve decision making and honor the wishes of patients and families.

Clinical TrialProlonged exposure therapy for older veterans with posttraumatic stress disorder: a pilot study.
: The purpose of this pilot study was to assess the feasibility and preliminary efficacy of prolonged exposure psychotherapy in older Veterans with posttraumatic stress disorder (PTSD). Exposure therapy has broad empirical support for PTSD, but it has not been studied systematically in older adults, partly due to published concerns that older adults would not tolerate the treatment. ⋯ : As hypothesized, Veterans showed a significant decrease in symptoms of PTSD (clinician-rated and self-reported) following exposure therapy.
