Reisberg Scale (Global Deterioration Scale)

The Reisberg Scale, also known as the Global Deterioration Scale, is a seven-stage model used to assess the progression of cognitive decline in individuals, particularly those with Alzheimer’s disease or other dementias. It ranges from Stage 1, where no cognitive decline is observed, to Stage 7, indicating severe impairment and the inability to carry on conversations or perform everyday tasks. Each stage reflects changes in memory, reasoning, and functional abilities, helping caregivers and healthcare professionals understand the severity of the condition and plan appropriate care needs.
