Alzheimer's Society comment on link between CETP gene and memory decline

There are rare inherited forms of Alzheimer's disease but the most common form is caused by a range of factors including: a combination of different genes, life style factors and life events.

Alzheimer's Society comment:

'Having a family member with dementia does not mean you will necessarily inherit the condition yourself. Alzheimer's disease, the most common dementia, is likely to be caused by interaction between genetic disposition, life style and life events. Many genes are probably involved each conferring a degree of risk.

However, research into genetics can help us better understand the processes that lead to the diseases that cause dementia and could potentially lead to new treatments.

This relatively small study suggests that variations in this particular gene - linked with long life and lower risk of heart disease - could also be associated with lower risk of dementia. More research is needed to fully understand this link. The government currently invests eight times less in dementia research than cancer research. This needs to change.'
