Other Criteria
Medical exclusion criteria for the subject sampling procedure at baseline were defined as those active or inactive medical conditions in the RNH problem list that may interfere with normal cognitive function. This definition included: chronic neurological pathology (dementia, mental retardation, cerebrovascular disease, epilepsy, parkinsonism, and CNS malignancies) or chronic psychotropic drug use, history of transient ischemic attackes (ITA), brain surgery, hemodialysis for renal failure, and electroconvulsive therapy. A score below 24 on the MMSE also excluded participants.
