Dementia


Dementia is a type of cognitive disorder that affects a part of the brain responsible for memory, learning, problem-solving and judgment.
 
The most common form of dementia is Alzheimer’s disease, a progressive disorder whose early symptoms include loss of recent memory, difficulty remembering names and nouns, poor judgment, trouble learning new information and poor concentration. In later stages of Alzheimer’s disease, a person must depend on others for total care. The course of the disease is generally from three to 15 years, with death usually resulting from complications of the illness such as malnutrition.
 
Other forms of dementia include vascular dementia, Lewy body dementia, frontotemporal dementia, Huntington’s disease, and Creutzfeldt-Jakob disease. Dementia also can be caused by reactions to medications, nutritional deficiencies, infections, poisoning and brain tumors, as well as anoxia or hypoxia, which occur when the brain’s oxygen supply is reduced or cut off altogether.
