How many stages are there in Alzheimer's disease?

The correct answer is that there are seven stages in Alzheimer's disease according to the commonly referenced framework developed by the Alzheimer's Association. This model breaks down the progression of the disease into distinct stages, each characterized by specific symptoms and changes in cognitive and functional abilities.

The seven stages are categorized as follows:

1. No Impairment: At this stage, there are no noticeable symptoms, and cognitive function is considered normal.
2. Very Mild Cognitive Decline: Individuals may experience slight memory problems that could be overlooked as a natural part of aging.
3. Mild Cognitive Decline: More evident memory issues can occur, and individuals may start having trouble with word finding and organization.
4. Moderate Cognitive Decline: This stage is marked by greater confusion and forgetfulness; individuals may struggle with tasks such as payment of bills or managing transactions.
5. Moderately Severe Cognitive Decline: Significant confusion can happen, and individuals may need assistance with daily activities, such as dressing or bathing.
6. Severe Cognitive Decline: Serious cognitive problems emerge, often requiring full-time supervision and care, as individuals may lose the ability to recognize family members and handle basic tasks.
