title: [Alzheimer's disease--considerations on the etiology and physiopathology based on a case report].
abstract: On the basis of a case report concerning a woman with severe dementia due to Alzheimer's disease who had a surprising mnestic comeback after mastectomy and lasting for 24 hours after operation, the hypothesis is presented that Alzheimer's disease is due to an age-related weakening in the blood-brain-barrier. Increased permeability might render a slight but constant influx of injurious endogenic substances possible. Serum cholinesterase is suggested as the primary injurious agent.
