What is Dementia?


As people get older the chances of developing dementia increase. Dementia is an umbrella term used to describe a category of brain diseases that cause long term decline in the ability to think and remember, to a degree that it interferes with the persons daily life. 

Although the specific diseases causing the dementia have their own cluster of symptoms, there is a lot in common in the care of all residents with dementia. The most common diseases causing dementia include Alzheimer’s disease, Lewy Bodies Dementia, Vascular dementia (also known as Multi-infarct dementia), Parkinson’s disease, Pick’s disease, Huntington’s disease (Chorea) and Alcohol-related dementia less common.  

Dementia is progressive. How severe, what symptoms and how quickly this occurs is different in each individual, however most people with severe dementia are cared for in Specialist Dementia units. Not all Rest Homes provide specialist dementia care as this requires both trained and skilled dementia care staff and a safe physical environment that meets strict Ministry of Health criteria.
