title: [Risk factors for dementia of the Alzheimer type].
abstract: A case-control study was conducted on 90 cases of "probable" Alzheimer's disease and 97 controls at the same age as patients with dementia of the Alzheimer type. The patients were diagnosed according to the DSM IIIR criteria. Information was obtained on birth and childhood, medical and surgical history, exposure to various social, psychological and biological factors, family history of dementia. A structured questionnaire was based on AMDP-system. Some of the variables studied reached statistical significance: first of all unfavourable factors (especially poor livelihood) taking place during the person's childhood, the level of education and social activity. Family history of dementia among persons with Alzheimer type dementia also reached statistical significance. Head trauma was more frequent in patients with dementia, but the differences were not significant. The findings suggest a possible etiologic role for some environmental factors in dementia of the Alzheimer type.
