AD is a slow disease that starts with mild memory problems and ends with severe brain damage. The time from diagnosis to death varies—as little as 3 or 4 years if the person is older than 80 when diagnosed to as long as 10 or more years if the person is younger. Other factors that affect how long a person will live with AD include the person’s sex, the presence of other health problems, and the severity of cognitive problems at diagnosis.

What is dementia?
Dementia is a general term that refers to a decline in cognitive function so extensive that it interferes with daily life and activities. This loss in the ability to think, remember, and reason is not a disease itself, but a group of symptoms that often accompanies a disease or condition.
Many conditions and diseases cause dementia. Two of the most common causes of dementia in older people are AD and vascular dementia, which is caused by a series of strokes or changes in the brain’s blood supply.
Other conditions that cause memory loss or dementia include:
* medication side effects
* chronic alcoholism
* certain tumors and infections in the brain
* blood clots in the brain
* vitamin B12 deficiency
* dehydration
* high fever
* some thyroid, kidney, or liver disorders
Many of these conditions are temporary and reversible, but they can be serious and should be treated by a doctor as soon as possible.
Emotional problems, such as stress, anxiety, or depression, can make a person more forgetful and can be mistaken for dementia. Someone may feel sad, lonely, worried, or bored when facing retirement or coping with the death of a spouse, relative, or friend. Adapting to these changes leaves some people feeling confused or forgetful. Supportive friends and family or professional help from a doctor or counselor can help older adults adjust to big changes.
