Screening and Diagnosis Detail
Consortium to Establish a Registry for Alzheimer's Disease (Morris 1989)
National Institute of Neurological and Communicative Diseases and Stroke/Alzheimer's Disease and Related Disorders Association Criteria (McKhann 1984)
"At baseline, each participant underwent a uniform structured clinical evaluation that followed the procedures recommended by the Consortium to Establish a Registry for Alzheimer’s Disease (16). The evaluation included a medical history, a neurologic examination, neuropsychological performance testing, and a review of a brain scan when available. All prescription and over-the-counter medication names and dosages were recorded after direct inspection of medication containers. A board-certified neuropsychologist (R.S.W.) reviewed the cognitive performance test results. Participants were evaluated in person by a neurologist (Z.A. or D.A.B.) or a geriatrician with expertise in the evaluation of older persons with and without dementia. Based on this evaluation, persons were classified with respect to AD, stroke, and other common conditions with the potential to impact cognitive function. Details of the evaluations have been previously described (15,17). The diagnosis of dementia and AD followed the recommendations of the joint working group of the National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer’s Disease and Related Disorders Association (18) The diagnosis of clinical stroke was based on review of the medical history, neurologic examination results, and neuroimaging data (brain computed tomography and/or magnetic resonance imaging scans) when available, as previously described (15). Follow-up evaluations were identical in all essential details to the baseline evaluation, and were performed annually by examiners blinded to previously collected data."
