Dementia And Depression - Dementia

Dementia And Depression

The symptoms of depression may sometimes mimic those of dementia. A depressed person may experience problems with memory, concentration and decision-making, while symptoms of sadness may be less noticeable.

The following symptoms indicate that depression may be the major issue rather than early stages of dementia:

Loss of interest or pleasure
Decreased or increased weight or appetite
Decreased or increased sleep
Appearing slow or agitated
Fatigue and loss of energy
Feeling worthless or guilty
Thoughts of death, suicide attempts or plans to commit suicide

Other symptoms that suggest depression include:

Little or no progression of memory loss
A family or personal history of depression
Mental tests results that show a person's memory is better than they say it is
Recent stress, such as bereavement

Your doctor may refer you for psychological evaluation to reach the correct diagnosis. Treating depression may restore memory function completely. However, it is important to remember that people with dementia can become depressed. This is a well-recognized complication of any stage of the disease. Because dementia and depression have similar symptoms and occur together, it may take a few visits and tests before a clear-cut diagnosis can be made.
