Is Dementia Reversible?

Is Dementia Reversible?

There is no cure for Alzheimer’s disease, the most common form of dementia, a degenerative brain disease. That said, there are some illnesses that cause dementia-like symptoms that medical experts say might be reversed.

For this reason, it is recommended that you or a loved one showing symptoms of dementia get a correct diagnosis as soon as possible.

According to Alzheimer Society Canada, the following are common causes of reversible dementia:

  • Head injuries
  • Drug and alcohol abuse
  • Medication side effects
  • Depression
  • Certain vitamin and mineral deficiencies
  • Thyroid issues
  • Heart disease

“Dementia is irreversible when caused by degenerative disease or trauma, but might be reversible in some cases when caused by drugs, alcohol, hormone or vitamin imbalances, or depression,” explains The Cleveland Clinic. “The frequency of ‘treatable’ causes of dementia is believed to be about 20 percent.”

Irreversible Dementia

Dementia that can possibly be treated, but not reversed or cured, includes the following:

Alzheimer’s disease

Lewy Body Dementia

Vascular Dementia

Parkinson’s Disease Dementia

Fronto-Temporal Dementia

Medical professionals agree that if someone suddenly experiences memory lapses, they should consult their health care provider to learn if it is something that can be reversed.
