A guide to dementia and its treatment
Dementia is a disorder that affects how the brain works. Symptoms of dementia vary from person to person, but can include:
- loss of memory
- difficulty thinking things through and understanding
- problems with language (reading and writing)
- confusion and agitation
- hallucinations and delusions
- difficulty controlling movements of the body.
Symptoms of dementia usually get worse over time and can become very severe, so that it is difficult for the person to do many daily activities or to care for him or herself.
Dementia is more likely to affect older people, but younger people can also develop the condition.
There are different types of dementia; the most common are:
- Alzheimer’s disease
- vascular dementia
- dementia with Lewy bodies
- frontotemporal dementia.
