Explanation of Dementia

Alzheimer's is only one form of dementia.

Dementia is a condition that causes a variety of changes in the brain to occur. Short-term memory loss and changes in socialization and behavior are signs of dementia. Alzheimer's disease is a common cause of the condition.

Definition

Dementia is a condition, not a disease, based upon changes in the brain. It affects a person's ability to handle activities of daily living and communication. Changes in personality may be apparent.

Types

Common forms of dementia include Alzheimer's disease, Parkinson's disease, Korsakoff's syndrome and vascular dementia--common in stroke victims.

Testing

Testing for dementia includes a physical and mental examination. Cognitive tests are given to determine function, memory, orientation and reasoning skills. The brain may be scanned using MRI and CT testing.

Prevention

According to the Mayo Clinic, high levels of alcohol consumption, smoking as well as high levels of cholesterol and blood pressure may increase the risk of a person developing dementia. Control the above factors to decrease your risk of of developing dementia.

Complications

As dementia progresses, a person will eventually stop eating and drinking. Personal hygiene such as bathing, dressing and toileting cannot be independently maintained. Dementia can cause a person to change emotionally. From aggression to anxiety, symptoms vary from person to person.
