Dementia or what we once knew as senility is a health threatening condition or disease that requires diagnosis and treatment from the doctor. Dementia usually occurs at the age of 65 or above. However, dementia is not part of the normal aging process. The things that increase the risk are age, family history (genetics), poor heart health, traumatic brain injury and race/ ethnicity.
Most common causes :
-Infections at the central nervous system
-Vascular disroders which affect our blood circulation in the human brain.
-alcohol or drug abuse.
-degenerative neurological disease
-delirium (is a mental state at which we are confused or disorientated)
There are many other causes of dementia like Parkinson’s disease, AIDS, alcohol and drug abuse, multiple sclerosis and other mental illness affecting the elderly like depression. It is important in these that a diagnosis from a medical doctor is very essential as they are similar symptoms to that of Alzheimer’s disease. While the 2 most common type of dementia are Alzheimer’s type dementia and Multiple-infarct dementia.
Alzheimer’s type Dementia
Alzheimer's disease is the most frequent form of dementia, which is a broad term for memory loss and other cognitive impairments that interfere with daily life. Alzheimer's disease is responsible for 60-80% of dementia cases. Alzheimer's disease is a degenerative condition in which dementia symptoms grow over time. Memory loss is minimal in the early stages of Alzheimer's, but people with late-stage Alzheimer's lose their capacity to converse and respond to their surroundings. There is currently no cure for Alzheimer's disease, although there are treatments for the symptoms and research is ongoing.
This is the result of a series of small ‘strokes’ in the brain. These mini strokes occur when arteries to the brain become blocked and the brain tissues are deprived of oxygen and nutrients. These mini strokes kill the brain cells related to our memory and thought process. The injured area is called an infarct.
