Dementia

Dementia is a general loss of mental abilities. It can include a loss of ability to think, reason, learn and understand. To be considered dementia, these mental losses must be severe enough to interfere with day-to-day activities. People with dementia must have:

  • Memory problems
  • Mental loss that is severe enough to cause problems with one or more of the following:
    • Language
    • Visuospatial function
    • Executive function (foresight, planning, anticipation, insight)
    • Praxis (learned motor skills)

What Causes Dementia?

Causes of dementia include:

Diagnosing Dementia

Your doctor may diagnose dementia through:

  • An extensive medical history from you and your family
  • Observing your behavior
  • A physical exam
  • Tests for your nervous system
  • Mental status and psychological tests

There are no blood tests or exams that can diagnose Alzheimer's disease. Certain types of brain imaging such as a SPECT or a PET scan may aid in a diagnosis. Tests to rule out other causes of dementia and other medical conditions that may mimic dementia include:

  • Blood tests
  • Lumbar puncture 
  • Electroencephalogram (EEG)

Imaging tests take pictures of internal body structures. These may include:

  • CT scan
  • MRI

Treating Symptoms of Dementia

Currently, there are no treatments to cure many types of dementia. Some medication may help to decrease your symptoms of dementia or slow its course.

Medications

There are two types of medications that may help reduce your symptoms of Alzheimer's disease. 

People with dementia often develop psychiatric symptoms. You may need appropriate treatment, such as:
