The Global Deterioration Scale for assessment of primary degenerative dementia

Am J Psychiatry. 1982 Sep;139(9):1136-9. doi: 10.1176/ajp.139.9.1136.


Cognitive decline associated with old age and consistent with the diagnosis of primary degenerative dementia is a unique clinical syndrome with characteristic phenomena and progression. The authors describe a Global Deterioration Scale for the assessment of primary degenerative dementia and delineation of its stages. The authors have used the Global Deterioration Scale successfully for more than 5 years and have validated it against behavioral, neuroanatomic, and neurophysiologic measures in patients with primary degenerative dementia.
