WHAT IS DEMENTIA?

Most people with dementia are older, but not all older people get dementia. It is not a normal part of ageing. Dementia can happen to anybody, but it is more common after the age of 65 years. People in their 40s and 50s can also have dementia (younger onset dementia).
Dementia describes a collection of symptoms that are caused by disorders affecting the brain. It is not one specific disease. Dementia affects thinking, behaviour and the ability to perform everyday tasks. Brain function is affected enough to interfere with the person’s normal social or working life. It can result in changes in personality, and affect a person’s ability to maintain relationships.
There are many different forms of dementia and each has its own causes. The most common types are; Alzheimer’s disease, vascular dementia, Parkinson’s disease, dementia with Lewy bodies, Fronto Temporal Lobar Degeneration (FTLD), Huntington’s disease, alcohol related dementia (Korsakoff’s syndrome) and Creutzfeldt-Jacob disease. You will find Help sheets on these and other types of Dementia in the ‘About Dementia’ section of the Help Sheets.
