The healthcare provider may recommend a psychiatric evaluation to determine if depression or another psychiatric disorder may be causing or contributing to a person's symptoms.
In most cases, testing people before symptoms begin in order to determine if they will develop dementia is not possible. However, in cases involving disorders such as Huntington's where a known gene defect is clearly linked to the risk of the disease, a genetic test can help identify people who are likely to develop the disease. Since this type of genetic information can be devastating, people should carefully consider whether they want to undergo such testing.
Dementia research scientists are examining whether a series of simple cognitive tests, such as matching words with pictures, can predict who will develop dementia. One study suggested that a combination of a verbal learning test and an odor-identification test could help identify Alzheimer's disease before symptoms become obvious. Other studies are looking at whether memory tests and brain scans can be useful indicators of future dementia.
