[Parkinson's disease and mental deterioration. Apropos of 30 cases].

The influence of Parkinson illness on intellectual faculties is appreciated in different ways. The existence of a real parkinson dementia is contested by some who see in the intellectual impoverishment of these patients a simple decline in efficiency. This is often partial and linked to neurological consequences which are not always taken into account by psychometric tests.

[Acute psychoses and mood disorders in Parkinson disease. Role of antiparkinson therapy].

L-DOPA has progressively replaced atropinic substances in the treatment of the Parkinson's disease but its superiority is not evident in all domains. The same as these substances, it can occasion a secondary psychical pathology essentially presented by affective disorders and psychotic phenomena. The proposed study lays on the comparison between two parkinsonian groups, one undergoing a dopaminergic treatment the other one not.

[Events in the lives of 120 chronic alcoholics. Preliminary study].

We have applied, with necessary modifications, life-events methodology, to the study of nature and temporal distribution of life-events occurring in 120 chronic alcoholics. Total number and distribution of life events undergo some variations with age, sex, ethnic group and socio-professional level in chronic alcoholics. We have specially analysed the temporal curve of life events before, during and after the year of beginning alcohol abuse.
