(HealthDay News) -- While dementia caused by Alzheimer's disease or brain damage from stroke are thought to be irreversible, some forms of memory loss may respond to treatment.
The U.S. National Library of Medicine offers this list of treatable causes of dementia:
- Brain tumor.
- Low levels of vitamin B12.
- A condition called normal pressure hydrocephalus, when a build-up of fluid presses on the brain.
- Certain thyroid problems.
