Cognitive impairment and dementia in Parkinson's disease: a controlled study.
The performance of 47 patients with Parkinson's disease on a battery of tests of cognition, motor function, disability and mood was compared with the performance of 47 healthy control subjects who were matched to the patients on the basis of age, sex and pre-morbid IQ. An increased prevalence of impairment over a range of cognitive functions was observed in the Parkinson's disease patients as compared with their matched controls. The differences between the Parkinson's disease patients and controls could not be accounted for by factors such as depressed mood, effects of medication or motor impairment. Our findings are discussed in relation to the methodology of previous studies in this area and to the need for a comprehensive clinico-pathological longitudinal study.

The circulation of firearm magazines was used as an index of gun ownership in the states of the USA. States with a higher per capita circulation of firearm magazines had higher suicide rates by gun and higher overall suicide rates. Homicide rates were unrelated to this measure of gun availability. Implications for the prevention of suicide are discussed.

Social support, dementia and depression among the elderly living in the Hobart community.
In a community sample of the elderly (N = 274) in Hobart, Tasmania, cases of dementia and depression were ascertained by the Canberra Geriatric Mental State and the Mini Mental State Examination. Social relationships and support were examined by means of the Interview Schedule for Social Interaction. The elderly had fewer social relationships than younger adults, but were more content with what they did have. ⋯ Persons with cognitive impairment or an established dementia reported that they had less social interaction than they would like. Depressed subjects reported having markedly less social interaction than the mentally healthy elderly, but did not complain that it was too little. This study provides a systematic description of the social environment of the elderly, both in mental health and in states of depression or impaired cognition.

Self-incineration: a controlled comparison of in-patient suicide attempts. Clinical features and history of self-harm.
A systematic survey of in-patient accidents and injuries in an inner London hospital over 9 years established that, after incisions and overdoses, self-incineration was one of the commoner methods of violent self-harm. A case-controlled study of in-patient suicide attempts compared a series of 12 self-incinerators with 12 patients using other methods. Irrespective of method, the suicide attempt was predominantly a psychotic act of young single people with chronic, severe disorders and considerable past parasuicide, in a setting of escalating self-harm. Younger age, greater psychiatric morbidity, absence of alcoholism, a history of childhood arson, past and current self-burning were the features specific to self-incineration, which had a 25% mortality rate.
