Possible risks of dementia
Some health or lifestyle factors have been connected with dementia. But these do not have enough evidence to say that they are major risk factors.
Behavioural risk factors
Some habits or behaviours can be associated with dementia, such as not getting enough sleep or taking caffeinated drinks. But more research is needed to properly understand the connection.
Medical risk factors
Research has shown a link between dementia and infections like herpes and pneumonia. But more research is needed to see if infections contribute to the development of dementia.
There is also not enough evidence to say that general anaesthetics increase a person’s risk of developing dementia.
