Dementia is a progressive brain dysfunction (in Latin 'dementia' means irrationality), which results in a restriction of daily activities and in most cases leads in the long term to the need for care. Many diseases can result in dementia, the most common one being Alzheimer's disease.

During the course of Alzheimer's disease, the elderly lose their independence in managing everyday life and become increasingly dependent on outside care. If you feel your senior is exhibiting signs of dementia or Alzheimer's disease, it may be time for them to be tested. At specialized centers, doctors can diagnose Alzheimer's disease correctly up to 90 percent of the time.

In Santa Cruz County, you can call (800) 272-3900 or (831) 464-9882, or go to  www.alznorcal.org to set up a test for your senior.
