This week marks Dementia Action Week, an opportunity to raise awareness of dementia, the types of dementia and some of the common symptoms.
What is dementia?
Dementia is a term to describe the symptoms that result from damage to the brain that gets worse over time, such as memory loss, confusion, problems with language, and behaviour changes.

The main types of dementia include:
- Alzheimer's disease -> This is the most common type and is caused by the abnormal buildup of plaques and tangles in neurons, the brain's nerve cells.
- Vascular dementia -> Also a common type, vascular dementia is caused by restricted blood flow to the brain. When the brain doesn't receive adequate oxygen and essential nutrients it can lead to cognitive impairment and memory loss.
- Lewy Body dementia -> This type of dementia is characterised by the presence of abnormal spherical structures in the brain called Lewy bodies which can develop within nerve cells.
- Frontotemporal dementia -> This type is a rare type of dementia and primarily affects behaviour and language. It affects the frontal and temporal lobes of the brain which are responsible for personality, emotional regulation, language and decision - making.
