There are over 200 subtypes of dementia, but the five most common are: Alzheimer’s disease, vascular dementia, dementia with Lewy bodies, frontotemporal dementia and mixed dementia.
The brain is made up of nerve cells that communicate with each other by sending messages. Dementia damages the nerve cells in the brain so messages can’t be sent from and to the brain effectively, which prevents the body from functioning normally.
Regardless of which type of dementia is diagnosed and what part of the brain is affected, each person will experience dementia in their own unique way.
Dementia can affect a person at any age but it is more commonly diagnosed in people over the age of 65 years. A person developing dementia before age 65 is said to have young onset dementia.
