NINCDS ADRDA
National Institute of Neurological and Communicative Diseases and Stroke/Alzheimer's Disease and Related Disorders Association Criteria (McKhann 1984)
Total dementia definition
: Dementia via DSM-IV.
"Diagnosis of dementia was based on a three-step procedure.
[12]. Trained psychologists administered a battery of neuropsychological tests. All the participants in Bordeaux and Montpellier were then examined by a neurologist at baseline, whereas in Dijon only those who screened positive underwent further examination because of the many participants. At follow-up, the participants who were suspected of incident dementia on the basis of their neuropsychological performance were examined by a neurologist in the three study centers. Finally, an independent committee of neurologists reviewed all potential prevalent and incident cases of dementia to obtain a consensus on its diagnosis and etiology according to the criteria of theDiagnostic and Statistical Manual of Mental Disorders, fourth edition[16]. Cases of AD were classified as probable or possible AD according to the National Institute of Neurological and Communicative Disorders and Stroke–Alzheimer’s Disease and Related Disorders Association criteria[1]."
