In fact, dementia isn't a specific disease. Instead, it is a group of symptoms affecting memory, thinking and social abilities severely.
Dementia involves damage of brain cells. This can occur in several areas of the brain. Dementia affects people differently, depending on the area of the brain affected.
The most common causes of dementia include:
- Degenerative neurological diseases, such as Alzheimer's disease, Parkinson's disease, Huntington's disease, and some types of multiple sclerosis.
- Vascular disorders affect the blood circulation in your brain.
- Traumatic brain injuries caused by car accidents, falls, concussions, etc.
- Infections of the central nervous system, such as meningitis, HIV, and Creutzfeldt-Jakob disease.
- Long-time alcohol or drug use.
- Certain types of hydrocephalus, a buildup of fluid in the brain
Some causes may be reversible, while others not. In addition, many factors can eventually lead to dementia like age and family history.
Finally, see a doctor if you or a loved one has memory problems or other dementia symptoms. Treatment depends on the cause of the condition, so it's important to determine the underlying cause.
