Who remembers the Royal Shakespeare Company production of Romeo and Juliet that followed the brilliant Peter Brook conception? Who can speak for 10 minutes about the U.S. President who succeeded Abraham Lincoln? How (if he hadn't lost his head for being a tax farmer) would Lavoisier have topped his discovery of the existence of oxygen? These thoughts crossed my mind on January 3rd as I took over day-to-day editorial responsibility for International Psychogeriatrics from Robin Eastwood.

The world's older population has been growing at a rate of 2.4% per year during the past decade, and in the year 2000 there were 580 million people aged 60 years or older (World Health Organization, 1998). With the 85 years and older group being the fastest growing segment of the population, age-related diseases and disabilities are rapidly increasing. Psychiatric morbidity is common in later life; 15% of older adults have clinically significant mental health disorders, with neurodegenerative conditions such as dementia taking the lead (Regier et al., 1998). Substantial progress has been made in the quest to unravel the pathophysiological mechanisms leading to dementia, improve the accuracy of early diagnosis, and develop dementia treatment-specific compounds. However, such developments may take decades to have a significant impact on clinical practice.

Background: Early diagnosis of Alzheimer's disease (AD) is critical for adequate treatment and care. Recently it has been shown that functional magnetic resonance imaging (fMRI) can be important in preclinical detection of AD. The purpose of this study was to examine possible differences in memory-related brain activation between persons with high versus low risk for AD. This was achieved by combining a validated neurocognitive screening battery (the 7-minutes test) with memory assessment and fMRI. Methods: One hundred two healthy community-living persons with subjective memory complaints were recruited through advertisement and tested with the 7-minutes test. Based on their test performance they were classified as having either high (n = 8) or low risk (n = 94) for AD. Six high-risk individuals and six age-, sex-, and education-matched low-risk individuals were investigated with fMRI while engaged in episodic memory tasks. Results: The high-risk individuals performed worse than low-risk individuals on tests of episodic memory. Patterns of brain activity during episodic encoding and retrieval showed significant gourp differences (p < .05 corrected). During both encoding and retrieval, the low-risk persons showed increased activity relative to a baseline condition in prefrontal brain regions that previously have been implicated in episodic memory. By contrast, the high-risk persons did not significantly activate any prefrontal regions, but instead showed increased activity in visual occipito-temporal regions. Conclusion: Patterns of prefrontal brain activity related to episodic memory differ between persons with high versus low risk for AD, and lowered prefrontal activity may predict subsequent disease.

Background: Activities of daily living (ADL) vary across cultures, and measure of ADL needs to be specific to the population under study. We developed an ADL measure for Thai elderly with dementia and investigated the reliability and validity of this instrument. Materials and Methods: Item construction was accomplished with a panel of neurologists and a rehabilitation medicine physician. One hundred eighty-one subjects were interviewed using the Thai ADL measure. Of this sample, one hundred fifty-nine had dementia according to the Diagnosic and Statistical Manual of Mental Disorders, fourth edition criteria. These data were analyzed for internal consistency; concurrent validity was determined by comparison with the Barthel Index, Functional Assessment Questionnaire (FAQ), Thai Mental State Exam (TMSE), and Clinical Dementia Rating (CDR) scale; and discriminant validity was determined by comparison with the Neuropsychiatric Inventory (NPI). Thirty subjects were tested to determine interrater and test-retest reliability. Results: Thai ADL measure was composed of six basic ADL and seven instrumental ADL. It had high correlation with TMSE scores (r = −.69), CDR scores (r = .81), Barthel Index scores (r = −.08), and FAQ scores (r = .88), and moderate correlation with NPI scores (r = .46). The instrument had high test-retest reliability (intraclass correlation coefficient [ICC] = .92, .89) and high interrater reliability (ICC = .96, .93). Conclusion: The Thai ADL scale is easy to use and it has high reliability. It had high concurrent validity with previously published ADL scales. The methodology used to develop the Thai ADL scale can provide a model for creating culturally competent ADL scales.

Background: We explored carer motivation for seeking participation for a relative in an Alzheimer's disease (AD) clinical drug trial, to assess impressions of the value of trial participation. We also surveyed the carers of patients who did not meet study entry screening criteria to see if our conduct of the screening visit was acceptable and ethical. Method: A retrospective questionnaire was sent to the carers of 36 randomized participants and 22 carers of patients who did not meet study entry screening criteria for an AD clinical treatment trial. Results: Twenty-nine (81%) of the trial participant carers and 15 (68%) of carers of the group who did not meet study entry criteria returned their questionnaires with sufficient information for analysis. The prime motivators in seeking trial participation were to help their relative feel better and live longer, to contribute to medical science, to improve the health of others, and the hope of a cure. Carers of both groups found research staff supportive and would recommend trial participatiion to others. Conclusions: Even though trial participation is onerous and patients were generally perceived by carers as not having improved, both the screening visit and participation in the trial itself were seen as positive experiences and the expectations of carers were met.

The rapid advances in biomedical sciences have induced special moral and ethical attitudes, which ought to be taken into account. One of the most essential issues is the principles for participation in research of subjects with reduced decision-making capacity. We conducted a questionnaire survey among members of the research ethics committees in Sweden to find out their attitudes to a range of ethical issues related to research on subjects with Alzheimer's disease. One hundred thirty-six of those approached responded (66%), and 117 of the responses (56%) were considered substantially complete. There were 16 questions with fixed reply alternatives. Some central questions concerned the informed consent process. With a few exceptions, there were no significant differences in attitudes between the experts and laypersons, between persons of different ages, and between men and women. However, women and laypersons were in general keener to preserve the patient's integrity and the experts were more willing than the laypersons to allow participation of subjects with dementia in placebo-controlled trials.

Background: Alzheimer's disease (AD) is associated with dependence in activities of daily living (ADL). In addition to the cognitive impairment resulting from AD, the presence of psychotic symptoms may further increase this dependence. The objective of this study was to quantify the additional contribution of psychotic symptoms to dependence in ADL. Method: We analyzed data from 558 individuals with AD referred to a memory clinic. Information on ADL, psychotic symptoms, depression symptoms, and cognition was collected with standardized instruments. Results: The frequency of psychotic symptoms was correlated with dependence in ADL (r = −.44, p < .001). The independent contribution of psychotic symptoms to ADL (basic and instrumental) after consideration for cognitive impairment and depression symptoms was assessed with hierarchical regression models. Twenty-five percent of basic ADL variance was explained by cognition; psychotic symptoms accounted for an additional 7% of the variance (b = −0.12, p < .001). Cognitive impairment explained 31% of instrumental ADL variance; psychotic symptoms accounted for an additional 6% (b = −0.21, p < .001). Discussion: Psychotic symptoms are associated with dependence in ADL after controlling for cognitive impairment and depression symptoms. Future research should investigate possible causal linkages between psychotic symptoms and dependence in ADL. This may have implications regarding interventions to maintain independent living in people with AD.

Increased sexual activity in patients with dementia is problematic for caregivers and has no proven treatment. This report decribes two male patients who had dementia with pronounced sexual acting out. One patient had vascular dementia and the other patient had Parkinson's disease with associated dementia. After nonresponse to neuroleptics and sedatives, low-dose cyproterone acetate successfully reduced sexual acting out without relevant side effects in both patients.

Objective: The aim of this study was to determine whether indirect self-destructive behaviors predict mortality in nursing home residents. Method: This cross-sectional study with follow-up after 2 years and 3 months surveyed 593 residents in 10 nursing homes in the eastern suburbs of Sydney, Australia. The following instruments were used: Harmful Behaviors Scale (HBS), Behavioral Pathology in Alzheimer's Disease Rating Scale (BEHAVE-AD), Functional Assessment Staging Scale, Resident Classificatin Index, Cumulative Illness Rating Scale, Even Briefer Assessment Scales for Depression, and the suicide item from the Structured Hamilton Depression Rating Scale. Diagnoses of depression, dementia, and psychosis were obtained from nursing home records. Mortality data were obtained in August 1999. Results: At follow-up, 297 (50.1%) residents were still alive with a mean survival time of 565.4 days. Survival analyses found that mortality was predicted by older age, male gender, lower level of functioning, lower levels of behavioral disturbance on the BEHAVE-AD, and higher scores on the HBS “passive self-harm” factor-based subscale, which includes refusal to eat, drink, or take medication. Discussion: These results suggest that passive self-harm behaviors predict mortality in nursing home residents.
