Dementia

DEMENTIA – CAUSES, SYMPTOMS, AND TREATMENT

Dementia, also called neurocognitive disorder, is a collective term used to describe various symptoms of cognitive decline. Dementia is not a single disease in itself, but a general term to describe the loss of cognitive functioning – thinking, remembering and reasoning and behavioral abilities to such an extent that it interferes with a person’s daily life and activities. These functions include memory, language skills, visual perception, problem solving, self-management and the ability to focus and pay attention. Some people with dementia find it difficult to control their emotions, and their personalities may change.

Dementia ranges in severity from the mildest stage, when it is just beginning to affect a person’s functioning, to the most severe stage, when the person must depend completely on others for basic activities for living.

The causes of dementia can vary, depending on the types of brain changes that may be taking place. Alzheimer’s disease is the most common cause of dementia. Alzheimer is characterized by “plaques” between the dying cells in the brain and “tangles” within the cells (both are due to protein abnormalities). The brain tissue in a person with Alzheimer’s has progressively fewer cells and connection and the total brain size shrink. Other causes of dementia include;

• Vascular disorders. These conditions affect the blood circulation in the brain.
• Traumatic brain injuries caused by car accidents, falls, concussions etc.
• Infections of the central nervous system. These include meningitis, HIV
• Long-time alcohol or drug use

Symptoms of dementia can vary greatly. Many conditions are progressive, which means that the signs of dementia start out slowly and gradually get worse. Possible symptoms of dementia compiled and published by the American Academy of Family Physicians (AAFP) include;

• Recent memory loss- a sign of this might be asking the same question repeatedly
• Difficulty completing familiar tasks
• Problems communicating – difficulty with language; forgetting simple words or using the wrong ones.
• Disorientation
• Problems with abstract thinking
• Misplacing things
• Mood changes

Treatment of dementia depends on its cause. In the case of most progressive dementias, including Alzheimer’s disease, there is no cure and no treatment that slows or stops its progression. But there are drug treatments that may temporarily improve symptoms. The same medications used to treat Alzheimer’s are among the drugs sometimes prescribed to help with symptoms of other types of dementias. Non-drug therapies can also alleviate some symptoms of dementia.
