Types of dementia

Dementia is the umbrella term for a number of neurological conditions, of which the major symptom includes a global decline in brain function.

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 1970s that dementia began to be described as we know it today.

We now know dementia is a disease symptom, and not a normal part of ageing.
