What are the Stages of Alzheimer’s Disease?
What are the Stages of Alzheimer’s Disease? very person with Alzheimer’s experiences the disease differently, but people tend to experience a similar trajectory from the beginning of the illness to its end. The precise number of stages of Alzheimer’s is somewhat arbitrary. Some experts use a simple three-phase model (early, moderate and end), while others have found a granular breakdown to be a more useful aid to understanding the progression of the illness.
An evalaution system, developed by Dr. Barry Reisberg of New York University, breaks the progression of Alzheimer’s disease into seven stages. . This framework for understanding the progression of the disease has been adopted and used by a number of healthcare providers as well as the Alzheimer’s Association.
First, Stages of Alzheimer’s Disease is Impairment
During this stage, Alzheimer’s is not detectable and no memory problems or other symptoms of dementia are evident.
Second, Stages of Alzheimer’s Disease are Very Mild Decline
The senior may notice minor memory problems or lose things around the house, although not to the point where the memory loss can easily be distinguished from normal age-related memory loss. The person will still do well on memory tests and the disease is unlikely to be detected by loved ones or physicians.
Third, Mild Decline
At this stage, the family members and friends of the senior may begin to notice cognitive problems. Performance on memory tests are affected and physicians will be able to detect impaired cognitive function.
Stages of Alzheimer’s Disease in stage 3 will have difficulty in many areas including:
- Finding the right word during conversations
- Organizing and planning
- Remembering names of new acquaintances
People with stage three Alzheimer’s may also frequently lose personal possessions, including valuables.
Fourth, Moderate Decline
In stage four of Alzheimer’s, clear-cut symptoms of the disease are apparent. People with stage four of Alzheimer’s:
- Have difficulty with simple arithmetic
- Have poor short-term memory (may not recall what they ate for breakfast, for example)
- Inability to manage finance and pay bills
- May forget details about their life histories
Fifth, Moderately Severe Decline
During the fifth stage of Alzheimer’s, people begin to need help with many day-to-day activities. Hence, Stages of Alzheimer’s Disease can be divided. People in stage five of the disease may experience:
- Difficulty dressing appropriately
- Inability to recall simple details about themselves such as their own phone number
- Significant confusion
On the other hand, people in stage five maintain functionality. They typically can still bathe and toilet independently. They also usually still know their family members and some detail about their personal histories, especially their childhood and youth.
Sixth, Severe Decline
People with the sixth stage of Alzheimer’s need constant supervision and frequently require professional care. Symptoms include:
- Confusion or unawareness of environment and surroundings
- Inability to recognize faces except for the closest friends and relatives
- Inability to remember most details of personal history
- Loss of bladder and bowel control
- Major personality changes and potential behavior problems
- The need for assistance with activities of daily living such as toileting and bathing
- Wandering
Seventh 7, Very Severe Decline
Stage seven is the final stage of Alzheimer’s. Because the disease is a terminal illness, people in stage seven are nearing death. In stage seven of the disease, people lose the ability to communicate or respond to their environment. While they may still be able to utter words and phrases, they have no insight into their condition and need assistance with all activities of daily living. In the final stages of Alzheimer’s, people may lose their ability to swallow.
