What are the stages of Alzheimer’s disease?
Numerous testing methods and procedures exist in neurology and psychiatry to determine the stages or severity of dementia. The most common procedures include the Mini-Mental Status Test (MMST), the Dementia Detection Test (DemTect), the Montreal Cognitive Assessment (MoCA), various ADL scales, the CERAD test collection and others.
In this context, we would like to highlight the GDS-Reisberg Scale (GDS = Global Deterioration Scale), as it differentiates between several stages and enables affected persons to assess the stage of the disease more accurately. The professional assessment is done by neurologists as well as family members and/or caregivers.
The scale was developed by Barry Reisberg, Clinical Director of the Silberstein Aging and Dementia Research Center at New York University School of Medicine (for more information on Prof. Reisberg, see: https://med.nyu.edu/faculty/barry-reisberg).
The following is a brief overview of the GDS Reisberg scale:
