GDS scale
Also written as: GDS — Global Deterioration Scale
Global Deterioration Scale that stages cognitive decline from normal cognition through severe dementia in seven levels.
Full Definition
The GDS (Global Deterioration Scale) is a clinical tool developed by Barry Reisberg to stage the progression of cognitive decline in primary degenerative dementia. The scale consists of seven stages ranging from normal cognition (Stage 1) to very severe cognitive decline (Stage 7). Each stage describes characteristic cognitive and functional changes, making it useful for tracking disease progression, planning interventions, and communicating with families about prognosis. In geriatric psychiatry, the GDS helps distinguish between normal aging, mild cognitive impairment, and various stages of dementia, facilitating appropriate treatment decisions and resource allocation.
