Causes of dementia

accreditation

Alzheimer’s disease causes more than half of all cases of dementia.

In 25% of cases, dementia is caused by blockages in the small blood vessels in the brain, which is known as vascular dementia. Trauma or head injury has been shown to result in dementia in about 15% of all cases. People with diabetes and hypertension are also at risk of getting dementia.

There are also several other common causes of dementia, which include:
•    Chronic infections
•    Poor nutrition
•    Heavy drinking over a long period of time
•    Parkinson’s disease
•    Hypothyroidism
•    Brain tumours
•    Multiple sclerosis
•    Renal (kidney) failure
•    Liver disorders
•    Inherited disorders such as Huntington’s disease and Tay-Sachs disease
•    Vitamin B1 (thiamine) or B12 deficiency
•    Toxins ( e.g. heavy metal poisoning)
