Treatable Causes of Dementia
Sometimes the physical examination reveals a condition that can be treated. Symptoms may respond to early treatment when they are caused by:
- Medication (including over-the-counter drugs).
- Alcohol.
- Delirium.
- Depression.
- Tumors.
- Problems with the heart, lungs, or blood vessels.
- Metabolic disorders (such as thyroid problems).
- Head injury.
- Infection.
- Vision or hearing problems.
Drug reactions are the most common cause of treatable symptoms. Older persons may have reactions when they take certain medications. Some medications should not be taken together. Sometimes, adjusting the dose can improve symptoms.
Delirium and depression may be mistaken for or occur with Alzheimer's disease. These conditions require prompt treatment.
