The Seven Stages of Alzheimer’s Disease

While some Alzheimer’s experts break the disease into three stages (early, moderate and end), Dr. Barry Reisberg from New York University developed a much more specific identification model with seven distinct stages. While the speed of the progress through the stages is different for each patient, the stages are present for everyone with the disease. As shared on www.alzheimers.net, the Seven Stages are:According to the Alzheimer’s Association, every 65 seconds someone in the US develops Alzheimer’s Disease. That means in the time it will take you to read this article, 8 people in will develop this disease. While there are 5.7 million Americans living with Alzheimer’s, by 2050 that number is projected to rise to nearly 14 million if a cure is not found. The statistics are staggering.

Alzheimer’s Disease is a progressive illness that increases in intensity and impact as time goes on. As Sir Francis Bacon said in 1597 (and was later oft-quoted by Thomas Jefferson), knowledge is power and knowing the Seven Stages of Alzheimer’s can empower you to adapt for yourself or your loved ones.

While some Alzheimer’s experts break the disease into three stages (early, moderate and end), Dr. Barry Reisberg from New York University developed a much more specific identification model with seven distinct stages. While the speed of the progress through the stages is different for each patient, the stages are present for everyone with the disease. As shared on www.alzheimers.net, the Seven Stages are:

Stage 1: No Impairment

During this stage, Alzheimer’s disease is not detectable, and no memory problems or other symptoms of dementia are evident.

Stage 2: 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 physicians or loved ones.

Stage 3: Mild Decline

At this stage, the friends and family members of the senior may begin to notice memory and cognitive problems. Performance on memory and cognitive tests are affected and physicians will be able to detect impaired cognitive function.

Patients in Stage 3 will have difficulty in many areas including:

  • finding the right word during conversations
  • remembering names of new acquaintances
  • planning and organizing

People with stage three Alzheimer’s may also frequently lose personal possessions, including valuables.

Stage 4: Moderate Decline

In stage four of Alzheimer’s disease clear cut symptoms of Alzheimer’s disease are apparent. Patients with stage four Alzheimer’s disease:

  • Have difficulty with simple arithmetic
  • May forget details about their life histories
  • Have poor short-term memory (may not recall what they ate for breakfast, for example)
  • Inability to manage finance and pay bill
  •  

 

Stage 5: Moderately Severe Decline

During the fifth stage of Alzheimer’s, patients begin to need help with many activities. People in stage five of the disease may experience:

  • ​​​​​​​Significant confusion
  • Inability to recall simple details about themselves such as their own phone number
  • Difficulty dressing appropriately

On the other hand, patients in stage five maintain a modicum of 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.

Stage 6: Severe Decline

Patients with the sixth stage of Alzheimer’s disease need constant supervision and frequently require professional care. Symptoms include:

  • Confusion or unawareness of environment and surroundings
  • Major personality changes and potential behavior problems
  • The need for assistance with activities of daily living such as toileting and bathing
  • Inability to recognize faces except closest friends and relatives
  • Inability to remember most details of personal history
  • Loss of bowel and bladder control
  • Wandering

​​​​​​​​​​​​​​

Stages 7: Very Severe Decline

Stage seven is the final stage of Alzheimer’s disease. Because Alzheimer’s disease is a terminal illness, patients in stage seven are nearing death. In stage seven of the disease, patients lose ability to respond to their environment or communicate. 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 the illness, patients may lose their ability to swallow.
