Explore the distinction between Alzheimer’s disease and dementia, with Alzheimer’s being the most prevalent cause of dementia. Understand the progressive nature of Alzheimer’s, leading to severe cognitive impairments.
Understanding the Reisberg Scale (GDS)
The Global Deterioration Scale (GDS) or Reisberg Scale provides a detailed 7-stage framework to assess Alzheimer’s stages, aiding in understanding symptoms and progression. This model helps differentiate between normal aging and advanced dementia.
1. Early Alzheimer’s Symptoms
Stage 1: No Cognitive Decline – No noticeable symptoms.
Stage 2: Very Mild Cognitive Decline – Often associated with normal age-related changes.
2. Alzheimer’s Stages and Symptoms
Stage 3: Mild Cognitive Decline – Noticeable memory lapses and word-finding difficulties.
Stage 4: Moderate Cognitive Decline – Difficulty in managing finances and planning complex tasks.
3. Severe Alzheimer’s Symptoms (Stages 5-7)
Learn about severe dementia as Alzheimer’s progresses:
- Stage 5: Moderately Severe Decline – Difficulty in recalling personal information such as address.
- Stage 6: Severe Decline – Increased need for daily living support, as seen in stage 6 Alzheimer’s.
- Stage 7: Very Severe Decline – Complete dependence, inability to communicate or respond.
Linking the Reisberg Scale with the Basic 3-Stage Model
This section demonstrates how the Reisberg Scale correlates with the simpler 3-stage dementia model, providing clarity on how early and late-stage dementia, as well as severe dementia, fit into comprehensive assessment tools.

What is Alzheimer's disease and how is it related to dementia?
Alzheimer’s disease is the most prevalent cause of dementia. It is a progressive neurological disorder leading to severe cognitive impairments, distinguishing itself from other forms of dementia.
What is the Reisberg Scale (GDS) used for?
The Global Deterioration Scale (GDS), or Reisberg Scale, is a 7-stage framework used to assess the stages of Alzheimer’s disease. It helps differentiate normal aging from advanced dementia, aiding in understanding symptoms and progression.
What symptoms are associated with early-stage Alzheimer's?
Early-stage Alzheimer’s symptoms include very mild to mild cognitive decline, which might involve memory lapses and occasional word-finding difficulties. Stages 1 and 2 are often associated with normal age-related changes.
How does moderate cognitive decline affect daily life?
Moderate cognitive decline, characterized by Stage 4 Alzheimer’s, can lead to difficulties in managing finances and planning complex tasks, requiring additional support.
What are the differences between Stage 6 and Stage 7 Alzheimer's?
Stage 6 involves severe decline with increased need for daily living support, while Stage 7 represents a very severe decline with complete dependence and inability to communicate or respond.
