Types of dementia

There are over 100 different types of dementia, most of which are very rare. We hear more about Alzheimer's Disease because it is the most common form, but most physical brain disorders involving memory loss, confusion and loss of skills and ability come under the general umbrella term of dementia.



Alzheimer's Disease

Alzheimer's disease is a brain disorder named for German physician Alois Alzheimer, who first described it in 1906. Scientists have learned a great deal about Alzheimer's disease in the century since Dr. Alzheimer first drew attention to it.

Vascular dementia

Vascular dementia is widely considered the second most common type of dementia. It develops when impaired blood flow to parts of the brain deprives cells of food and oxygen.

Mixed Dementia

Mixed dementia is a condition in which Alzheimer's disease and vascular dementia occur at the same time. Many experts believe mixed dementia occurs more often than was previously realised and that it becomes increasingly common in advanced age.

Lewy Bodies dementia

Dementia with Lewy bodies is characterised by abnormal deposits of a protein called alpha-synuclein that form inside the brain's nerve cells called 'Lewy bodies'. Lewy bodies have been found in several brain disorders, including dementia with Lewy bodies, Parkinson's disease and some cases of Alzheimer's.

Frontotemporal dementia/Pick's Disease

Frontotemporal dementia and Pick's disease can effect people in their 40s and 50s and it's onset is more rapid than Alzheimer's. Early symptoms are more likely to be changes in behaviour rather than memory loss.

Early onset dementia

Although dementia mostly affects people who are elderly, dementia can occur in younger people and, very rarely, in children. Because it is difficult to diagnose at an early age it is important to seek medical help early.
