Using our Alzheimer’s life expectancy calculator, you can estimate the average lifespan of a person with the illness based on its seven phases of progression (Global Deterioration Scale).
Alzheimer’s Life Expectancy Calculator
A gradual neurological disorder, Alzheimer’s disease often affects persons over the age of 65. It is the most prevalent dementia and results in significant cognitive impairment due to complicated brain abnormalities. You might be curious about the life expectancy of someone with Alzheimer’s due to the disease’s progressive nature. Join us to get the answers to the following inquiries:

Overview of Alzheimer’s disease
Alzheimer’s disease is a chronic, advancing brain condition that affects 60 to 80 percent of dementia sufferers. Alzheimer’s patients increasingly exhibit symptoms like:
- Memory decline;
- Difficulty with planning and with problem-solving;
- Difficulty in completing everyday tasks;
- Difficulty in concentrating and bouts of confusion;
- Difficulty in comprehending spatial relationships;
- Trouble with making reasonable judgments;
- Difficulty in coping with unfamiliar situations;
- Changes in personality and mood (depression, irritability, mood swings, or restlessness); if you want to learn more about depression and anxiety, visit Omni depression screening by PHQ-2 calculator and GAD-7 calculator, accordingly;
- Impulsive behavior and aggressiveness.
It is believed that alterations in the brain are what are causing these symptoms. Among these alterations include the formation of amyloid (harmful) plaques and aberrant buildups of a protein that sever connections between brain cells. Brain tissue begins to shrink as a result of the death of brain cells.
The hippocampus, a region of the brain involved in learning and memory, is where these changes in the brain typically start, and this is why memory loss is one of the first symptoms to manifest. Unfortunately, persons who have Alzheimer’s disease have a shorter life expectancy. Read on to learn about the seven phases of Alzheimer’s disease and how our life expectancy calculator for the condition functions.
The Alzheimer’s life expectancy calculator — what is the life expectancy of an Alzheimer’s patient?
The Alzheimer’s life expectancy calculator uses the seven stages of Alzheimer’s disease, as defined by the Global Deterioration Scale.
|1||No cognitive impairment.|
|2||Very mild cognitive decline.|
|3||Mild cognitive decline.|
|4||Moderate cognitive decline.|
|5||Moderately severe cognitive decline.|
|6||Severe cognitive decline.|
|7||Very severe cognitive decline.|
Simply stating the Alzheimer’s disease stage of development is all that is required. You may use the calculator to find out the stage’s approximate duration as well as the stage-specific life expectancy. We go into further depth about these stages in the next section.
Alzheimer’s stages life expectancy — the 7 stages of Alzheimer’s disease
Age, general health, early diagnosis, and treatment of Alzheimer’s disease can all have a significant impact on a person’s life expectancy. However, depending on the stage of the disease’s progression, we may generally respond to the question: “What is the life expectancy of someone with Alzheimer’s?” (and the accompanying degree of cognitive impairment).
- In the first stage, there are no known estimations regarding the life expectancy, and symptoms are mostly silent.
- In the second stage, subtle changes may appear — although those changes may just be due to aging, and not be related to Alzheimer’s disease at all. In this stage, the estimated life expectancy is more than ten years.
- During the third stage (which lasts from 2 to 7 years), the symptoms of Alzheimer’s disease (memory decline, misplacing objects, trouble organizing, planning, etc.) become more apparent. Here, the estimated life expectancy is around ten years.
- During the fourth stage, the symptoms that were detected in the third stage become more obvious, and the person may appear more withdrawn and moody. The estimated life expectancy is between 3 to 8 years in this stage.
- In the fifth stage, the person may need help performing everyday activities. Memory decline is very apparent — a person may not recall important details and events of their life. The estimated life expectancy is between 1.5 and 6.5 years in this stage.
- During stage six, the patient may forget names, be unaware of their environment, have trouble dressing adequately, and display significant personality and behavior changes. Life expectancy for this stage is four years or less. If you want to check the independence of a person in terms of daily self-care and mobility, use Omni barthel index calculator.
- In the seventh stage (which lasts 2.5 years or less) verbal abilities are progressively lost, as well as psychomotor skills.
Life expectancy in the various phases of Alzheimer’s varies, therefore it’s important to get a complete clinical examination in consultation with a doctor. Although Alzheimer’s can reduce life expectancy, with the right care and attention, the quality of life for people who have the condition may be greatly increased.
How is Alzheimer’s disease diagnosed?
Diagnosing Alzheimer’s disease requires careful clinical evaluation, and there is no single assessment tool to make the diagnosis.
Does Alzheimer’s shorten life expectancy?
Unfortunately, Alzheimer’s disease is a progressive condition that does shorten life expectancy. By how much the lifespan is affected depends on the stage of the disease development at the time of diagnosis.
What is Alzheimer’s life expectancy at stage 6?
At stage 6 of Alzheimer’s disease (characterized by severe cognitive decline), the estimated life expectancy is four years or less.
What is the life expectancy of someone with Alzheimer’s?
Depending on the stage of disease development at the diagnosis, the life expectancy of someone with Alzheimer’s disease varies from 3 to 11 years.
How do I calculate Alzheimer’s life expectancy?
You can estimate the approximate life expectancy of someone with Alzheimer’s disease according to stages of disease development. However, the stage durations may vary depending on age, general health, and the time of diagnosis.
