Dementia is the umbrella term for a number of neurological conditions, of which the major symptom includes a global decline in brain function.
It is a condition that has been noted in people for hundreds of years.
Dementia was a relatively rare occurrence before the 20th century as fewer people lived to old age in pre-industrial society. It was not until the mid 1970’s that dementia begun to be described as we know it today.
We now know dementia is a disease symptom, and not a normal part of aging.
There are over 100 diseases that may cause dementia. The most common causes of dementia include Alzheimer’s disease, vascular dementia and dementia with Lewy bodies.
