Very few studies from India have studied the phenomenology of delirium. The aim of the present study was to study the phenomenology as measured using the Delirium Rating Scale-Revised-98 (DRS-R98), the associated etiologies and the outcome of delirium among the elderly participants seen by the consultation-liaison psychiatric service in India. In addition, an attempt was made to study the factor structure of symptoms using principal components analysis. ⋯ Results suggest that the symptoms of delirium as assessed by DRS-R98 separate out into a three-factor structure. Delirium is commonly associated with metabolic endocrine disturbances and about one-sixth of the patients die during the short inpatient stay.

Few people with dementia have made advance plans for their health care. Advance care planning (ACP) is a process of discussion between an individual and their care providers that takes account of wishes and preferences for future care. We aimed to examine the facilitators and inhibitors to ACP in people with dementia. We also aimed to identify key themes in the literature and critically review the methodologies used. ⋯ The current evidence base for ACP in dementia is limited. Since UK government policy recommends that all people should engage in ACP, more evidence is needed to understand the feasibility and acceptability of advanced care plans for people with dementia.

There is no valid instrument currently in use at acute-care hospitals in Hong Kong to aid the detection of cognitive impairment. The objectives of this study were to (1) validate the Digit Span Test (DST) in the identification and differentiation of dementia and delirium; and (2) determine the prevalence of major cognitive impairment in elderly people in an acute medical unit. ⋯ Dementia and delirium were prevalent, yet under-recognized, in acute medical geriatric inpatients. The DSB is an effective tool in identifying patients with major cognitive impairment.

The study of mental disorders in the elderly presents substantial challenges due to population heterogeneity, coexistence of different mental disorders, and diagnostic uncertainty. While reliable tools have been developed to collect relevant data, new approaches to study design and analysis are needed. We focus on a new analytic approach. ⋯ Latent class analysis and hidden Markov chains offer a promising tool for studying mental disorders in the elderly. Its use may show its full potential as new data become available.
