Dementia

What is Dementia?

Dementia is an illness that causes the brain cells to deteriorate rapidly than the average rate. Currently, there are no cure found for this abnormal aging process. People suffering from dementia will gradually lose their cognitive abilities, and go through sudden personality changes. This affects adults at any point in their lives, although it is evidently more prominent in elderly people over the age of 65 years old. An estimate of 6.2 percent of people within this age group are suffering from this illness in Singapore.

Various kinds of dementia:

- Alzheimer's disease resulting from a combination of genetic and lifestyle risk factors

- Vascular dementia (multi-infarct dementia) resulting from multiple brain strokes

Causes

There are many factors leading up to Dementia where if the brain is exposed to multiple strokes then Vascular Dementia can occur.

Certain degenerative neurological diseases, for example Creutzfeldt-Jakob Disease, Parkinson's Disease, Huntington's Disease, and multiple sclerosis can cause Dementia.

Additionally, there can be be some triggers that can accelerate the development of Dementia, for instance the Human Immunodeficiency Virus (HIV) and some central nervous system infections, such as Meningitis (inflammation of the brain membrane).

Other concerning factors includes traumatic injury to the brain caused by a sudden fall or automobile accidents, abuse of alcohol and drugs, depression, family history of dementia, and increasing age.
