title: No association of paraoxonase genotype or atherosclerosis with cerebral amyloid angiopathy.
abstract: OBJECTIVE
  Both cerebral amyloid angiopathy (CAA) and paraoxonase have been reported to be related to lipid metabolism and atherosclerosis. We investigated whether the paraoxonase gene (PON1) polymorphism and atherosclerosis are associated with risk of CAA.
  
  
  METHODS
  Associations of the PON1 polymorphism and atherosclerosis of the aorta and coronary and cerebral arteries with the severity of CAA were investigated in 154 elderly Japanese individuals, including 47 patients with Alzheimer's disease.
  
  
  RESULTS
  The PON1 polymorphism or severity of atherosclerosis of the arteries was not associated with the severity of CAA.
  
  
  CONCLUSIONS
  The PON1 polymorphism and atherosclerosis would not appear to be associated with risk of CAA in the elderly, although further study with larger samples is necessary for confirmation.
