What Causes Dementia

Dementia is a brain disorder that affects different areas of the brain. The disorder causes problems to a person’s personality and memory. The causes of dementia vary. The disorder is most common in the elderly, but can occur in people of all different ages. 

Dementia affects the areas of the brain that control a person’s memory. They may develop issues with their memory such as problems remembering people, places and things. The causes of dementia vary. The disorder is brought on by a previous issue that affects the brain and poisons areas of the brain that affect a person’s cortex of the brain or the area below the cortex.

Alzheimer’s disease is the most common cause of dementia. Alzheimer’s affects a person’s brain by killing of the cells. Once the cells in the brain have been killed, they cannot be regenerated. The death of the cells affects a person’s brain and leads to the disorder of dementia. Another common cause of dementia is a stroke. A stroke may cause dementia to occur in a person because a stroke affects the blood vessels of the brain. When the blood vessels have been constricted, they deprive the brain from receiving oxygen, which can then lead to damage of the brain and dementia.

Other diseases are less commonly a cause, but have been known to cause dementia is certain cases. HIV, AIDS, Huntington’s disease, multiple sclerosis and Parkinson’s disease have all been known to cause dementia. People suffering from one of these issues may be checked routinely by a doctor for the early signs of dementia.
