          Abstract

          Background/Aims: The aim of this study was to compare the presence and severity of dementia in two large cross-sectional samples of nursing home residents from 2004/2005 and 2010/2011. Methods: Demographic information as well as data on the type of nursing home unit, length of stay before assessment, physical health, regularly used prescribed drugs and Clinical Dementia Rating scale scores were used in the analyses. Logistic and linear regression models for hierarchical data were estimated. Results: The odds of the occurrence and of a greater severity of dementia were higher in 2010/2011 than in 2004/2005. Independent of the time of study, married men had more severe dementia than single men, and single women had more severe dementia than single men. Conclusion: The findings may reflect the increase in the need for more nursing home beds designed for people with dementia between 2004/2005 and 2010/2011.

          Prevalence of psychiatric disorders among older adults in long-term care homes: a systematic review.

          The population of older adults in long-term care (LTC) is expected to increase considerably in the near future. An understanding of the prevalence of psychiatric disorders in LTC will help in planning mental health services for this population. This study reviews the prevalence of common psychiatric disorders in LTC populations. We searched electronic databases for studies on the prevalence of major psychiatric disorders in LTC using medical subject headings and key words. We only included studies using validated measures for diagnosing psychiatric disorders or psychiatric symptoms. Our review focused on the following psychiatric disorders: dementia, behavioral and psychological symptoms of dementia (BPSD), major depression, depressive symptoms, bipolar disorder, anxiety disorders, schizophrenia, and alcohol use disorders. We also determined the prevalence of psychiatric disorders in the U.S. LTC population using data from the 2004 National Nursing Home Survey (NNHS). A total of 74 studies examining the prevalence of psychiatric disorders and psychological symptoms in LTC populations were identified including 30 studies on the prevalence of dementia, 9 studies on behavioral symptoms in dementia, and 26 studies on depression. Most studies involved few LTC facilities and were conducted in developed countries. Dementia had a median prevalence (58%) in studies while the prevalence of BPSD was 78% among individuals with dementia. The median prevalence of major depressive disorder was 10% while the median prevalence of depressive symptoms was 29% among LTC residents. There were few studies on other psychiatric disorders. Results from the 2004 NNHS were consistent with those in the published literature. Dementia, depression and anxiety disorders are the most common psychiatric disorders among older adults in LTC. Many psychiatric disorders appear to be more prevalent in LTC settings when compared to those observed in community-dwelling older adults. Policy-makers and clinicians should be aware of the common psychiatric disorders in LTC and further research into effective prevention and treatments are required for this growing population.

            The prevalence of psychiatric symptoms and behavioural disturbances and the use of psychotropic drugs in Norwegian nursing homes.

            Psychiatric and behavioural symptoms in dementia are associated with a range of negative outcomes, including institutional placement and the widespread use of psychotropic drugs in spite of limited evidence for their efficacy. To determine the prevalence of psychiatric and behavioural symptoms and the pattern of psychotropic drug prescription in patients with various degrees of dementia. A sample of 1,163 non-selected nursing home patients were assessed by means of the Neuropsychiatric Inventory, the Clinical Dementia Rating scale and Lawton's activities of daily living scale. In addition, information was collected from the patients' records. Dementia was found in 81% of the patients and 72% of them had clinically significant psychiatric and behavioural symptoms. The frequencies of symptoms increased with the severity of the dementia. Psychotropic medication was being prescribed to 75% of patients with dementia. There was a significant relationship between the type of drug and the symptom for which it had been dispensed. Psychiatric and behavioural symptoms are frequent in nursing homes and the rate increases with the progression of the dementia. Systematic programmes are needed for disseminating skills and providing guidance regarding the evaluation and treatment of these symptoms in nursing homes.

              Prevalence of dementia in the elderly in Europe.

              Dementia is an important public health problem as it is one of the most common diseases in the elderly and a major cause of disability and mortality. This review on dementia is restricted to European Union countries where the overwhelming majority of studies have been undertaken, and will also refer to the EURODEM publications which may be considered to be the principal European reference point in this area. In subjects aged over 65, crude prevalence rates for dementia varied between 5.9% and 9.4%. We discuss the major problems limiting the use of these estimations, limits which may differ according to the area of application, be it etiological research or care provision.
