Asbestos exposure and Alzheimer disease.

10 cases in which an asbestos-related disease (malignant pleural mesothelioma or asbestosis) was associated with severe Alzheimer type lesions in the brain are reported. The patients, all males aged between 67 and 78 years, had been occupationally exposed to asbestos in the shipbuilding industry. The hypothesis that asbestos is a favoring factor in the genesis of Alzheimer disease is discussed.
