Dementia is a term for several diseases that affect memory, thinking, and the ability to perform daily activities.

The illness gets worse over time. It mainly affects older people but not all people will get it as they age.

Things that increase the risk of developing dementia include:

• Age (more common in those 65 or older)
• High blood pressure (hypertension)
• High blood sugar (diabetes)
• Being overweight or obese
• Smoking
• Drinking too much alcohol
• Being physically inactive
• Being socially isolated
• Depression

Dementia is a syndrome that can be caused by a number of diseases which over time destroy nerve cells and damage the brain, typically leading to deterioration in cognitive function (i.e. the ability to process thought) beyond what might be expected from the usual consequences of biological ageing. While consciousness is not affected, the impairment in cognitive function is commonly accompanied, and occasionally preceded, by changes in mood, emotional control, behaviour, or motivation.

Dementia has physical, psychological, social and economic impacts, not only for people living with dementia, but also for their carers, families and society at large. There is often a lack of awareness and understanding of dementia, resulting in stigmatization and barriers to diagnosis and care.
