Neurodegenerative disease is part of the mechanism of memory formation.
Neurodegenerative simply refers to the lessening of efficiency and effectiveness of the nervous system (particularly in the brain) over time. Dementia and Alzheimer’s disease exemplify this.
Dementia is a chronic disorder which inhibits brain functioning, exemplified by ineffective memory retrieval. Dementia is largely caused by injury or disease. So burdensome has dementia become that it has recently been added as the ninth National Health Priority Area. The most common type of dementia is Alzheimer’s disease:
Alzheimer’s disease, as above, is the most common known form of dementia. It is a neurodegenerative disease exemplified by memory loss (including retrograde and anterograde amnesia), vagueness, mood swings, loss of reasoning and confused thinking. Brain cells of sufferers of Alzheimer’s disease slowly die, and the brain essentially, therefore, shrinks.
