Symptoms

The disease begins as mild memory lapses. It moves to profound loss of memory and function. Alzheimer's disease is divided into three stages:

  • Early—memory and cognition loss are noticeable but still able to function independently
  • Intermediate—mental loss, personality changes more dependent on others for basic needs
  • Severe—loss of personality and bodily functions; total dependence for care

Symptoms include:

  • Increasing trouble remembering things, such as
    • How to get to familiar places
    • Names of friends and family members
    • Where common objects are kept
    • Simple math
    • How to perform tasks (eg, cooking, dressing, bathing)
  • Trouble concentrating on tasks
  • Trouble completing sentences due to lost or forgotten words (progresses to a complete inability to speak)
  • Difficulty with daily life tasks such as bill paying and housekeeping
  • Inability to remember the date, time of day, season
  • Mood swings
  • Withdrawal, loss of interest in usual activities
  • Slow, shuffling walk
  • Poor coordination
  • Slowness and then loss of purposeful movement

Diagnosis

There are no tests to definitively diagnose this disease. The doctor will ask about your symptoms and medical history. A physical exam will be done. The doctor will ask many questions. This will help to rule out other causes.

Tests to rule out other medical conditions may include:

  • Neurological exam
  • Psychological and mental status testing
  • CT scan —a type of x-ray that uses a computer to make pictures of the brain
  • MRI scan —a test that uses magnetic waves to make pictures of the brain
  • Electroencephalogram (EEG) —a test that measures electrical currents in the brain
  • Blood tests and urine tests
  • Lumbar puncture —to test for levels of certain brain proteins that increase with Alzheimer’s disease and to rule out other disorders
