title: Antibodies to choroid plexus in senile dementia of Alzheimer's type.
abstract: OBJECTIVE
  To investigate whether autoantibodies to choroid plexus are present in human senile dementia.
  
  
  METHODS
  Serum samples from 40 elderly people presenting with characteristic, diagnostic criteria of senile dementia of Alzheimer's type and 20 age matched healthy controls were tested by indirect immunofluorescence for the presence of autoantibodies to choroid plexuses, using frozen sections of rat or human fetal brain tissue.
  
  
  RESULTS
  Significant labelling of choroid plexus basement membrane was observed in 17 of the 40 samples from patients with senile dementia; in the control series one sample of rat but not human plexus labelled positively (p < 0.01).
  
  
  CONCLUSIONS
  The antibodies identified in this series of patients with Alzheimer's disease suggest that autoimmune mechanisms might be responsible for some of the changes in cerebrospinal fluid production described in this disorder.
