Parkinsonism is very common among people over the age of 65, and its prevalence increases markedly with age. Parkinsonism is associated with a twofold increase in the risk of death, which is strongly related to the presence of a gait disturbance.

Markers of lower socioeconomic status predict risk of developing incident AD. The mechanism of this relation is uncertain, but the possibility that it reflects unidentified and potentially reversible risk factors for the disease deserves careful investigation.

The incidence of Alzheimer's disease is substantial and is approximately 14 times higher among persons older than 85 years compared with those between 65 and 69 years of age.

To study delirium in hospitalized elderly, a delirium symptom interview (DSI) was developed by an interdisciplinary group of investigators. This interview was administered in an acute care hospital to 50 patients who were over the age of 65 years. Results from the interview were compared to assessments of major symptoms of delirium made independently by a neurologist and a psychiatrist. This interview had good validity and reliability. The sensitivity of the DSI was .90 and the specificity was .80, when compared with the clinical judgment of a psychiatrist and neurologist. Interrater reliability, using lay interviewers, was .90 for the detection of major symptoms of delirium. These results indicate that the DSI could be used by lay interviewers to assess reliably the symptoms of delirium.

The importance of strengthening research on the implementation and dissemination of promotion, prevention and service delivery interventions in the mental health field needs to be emphasized. The complexity of mental health and its broader conceptualisation requires complementary research approaches and interdisciplinary collaboration to better serve the needs of the European population.

After more than 90 years of research in which the presence or absence of a diagnosis of schizophrenia has been used as an independent variable, little of certainty has been found out about the aetiology of the hypothesized schizophrenia disease process. One possible reason for this lack of progress is that schizophrenia is not a valid object of scientific inquiry. Data from published research (mainly carried out by distinguished psychiatrists) are reviewed casting doubt on: (i) the reliability, (ii) the construct validity, (iii) the predictive validity, and (iv) the aetiological specificity of the schizophrenia diagnosis. It is argued that continued research into the aetiology of schizophrenia is likely to prove fruitless and that psychologists should adopt alternative methods of studying psychosis. Two alternative strategies--the development of empirical methods of psychiatric classification and the study of individual symptoms--are discussed.

The second edition of this acclaimed book offers a critical analysis of the transition from institutional to community care for people with mental health problems. Despite the almost complete abandonment of the old Victorian asylum system, the powerful cultural legacy of segregation remains potent in modern thought. Rogers and Pilgrim analyse the impact of new policies introduced by the Labour government since it came to power in 1997, identifying both the processes and causes of policy change and assessing its value in the context of longer term debates about madness and distress.
