Moderate Alzheimer's Disease

As AD progresses, deficits in memory, language, and reasoning become more noticeable. Changes in personality and behavior become more extreme. At this point, a person may begin to endanger themselves or others.

Symptoms of moderate AD may include the following:

  • Difficulty identifying familiar people, places, or things
  • Restlessness
  • Sleep disturbances
  • Poor judgment or difficulty with reasoning
  • Aggression or agitation
  • Inappropriate behavior
  • Increased difficulty with everyday activities
  • Losing touch with reality
  • Suspiciousness or paranoia
  • Hallucinations

Only a doctor can diagnose AD. If you are concerned about your cognitive function, or if you notice worrisome symptoms in someone you love, contact your healthcare provider.
