Alzheimer's disease

Table of Contents

As the AD becomes worse, symptoms are more obvious and interfere with your ability to take care of yourself. Symptoms can include:

  • Forgetting details about current events
  • Forgetting events in your own life history, losing awareness of who you are
  • Change in sleep patterns, often waking up at night
  • Difficulty reading or writing
  • Poor judgment and loss of ability to recognize danger
  • Using the wrong word, mispronouncing words, speaking in confusing sentences
  • Withdrawing from social contact
  • Having hallucinations, arguments, striking out, and violent behavior
  • Having delusions, depression, agitation
  • Difficulty doing basic tasks, such as preparing meals, choosing proper clothing, and driving

People with severe AD can no longer:

  • Understand language
  • Recognize family members
  • Perform basic activities of daily living, such as eating, dressing, and bathing

Other symptoms that may occur with AD:

  • Incontinence
  • Swallowing problems

Signs and tests

AD can often be diagnosed through a history and physical exam by a skilled doctor or nurse. A health care provider will take a history, do a physical exam (including a neurological exam), and perform a mental status examination.

Tests may be ordered to help determine whether other medical problems could be causing dementia or making it worse. These conditions include:

  • Thyroid disease
  • Vitamin deficiency
  • Brain tumor
  • Stroke
  • Intoxication from medication
  • Chronic infection
  • Anemia
  • Severe depression

Computed tomography (CT) or magnetic resonance imaging (MRI) of the brain may be done to look for other causes of dementia, such as a brain tumor or stroke.

  • In the early stages of dementia, brain image scans may be normal. In later stages, an MRI may show a decrease in the size of different areas of the brain.
  • While the scans do not confirm the diagnosis of AD, they do exclude other causes of dementia (such as stroke and tumor).
