Dementia is a word used to describe a group of symptoms; it is not a disease itself. This group of symptoms include: 

 

• memory loss 

• confusion 

• mood and behavioural changes 

• vision, language and communication problems. 

 

Dementia is caused by different diseases that affect the brain. Alzheimer’s disease is the most common cause of dementia. These diseases damage brain cells, causing dementia symptoms to get worse over time. People living with dementia will need more support and help with everyday life as time goes on.
