Almost all of us have heard the word dementia but what exactly is it? Dementia is an umbrella term used to describe a number of conditions characterised by a decline in memory loss, problem-solving, language and behaviour that affects a persons ability to perform an everyday task.

Many dementias are progressive, meaning symptoms start out slowly and gradually get worse normally over a period of four to twenty years.

Alzheimer’s disease is the most common form of dementia accounting for 60-80% of cases. However, there are different types, for example, Lewy Body, Vascular and Frontotemporal dementia. For more information click here
