This is a very difficult area. Vascular dementia takes many decades to develop and is only differentiated with certainty from some other dementias post mortem. Therefore the research relies on correlational studies. Alzheimer's Society (deals with all dementias despite the name) and Alzheimer's Disease Research have websites which provide introductions to the issue. Basically the main controllable risk factors seem to be lifestyle (diet, exercise, alcohol, substances) and perhaps "cognitive exercise" (learning a language, working on something mentally challenging, crosswords) but with the latter I am not sure about applicability to vascular dementia per se. Age is the biggest risk factor as you know and we can't do much about that. The gold standard here would be cross-longitudinal work through to post mortem. I don't know if there are any studies but this type of work is expensive, ambitious and a very long term commitment.

In the first place there is no definite consensus on the definition of vascular dementia, moreover there is a great overlap between vascular dementia and Alzheimers dementia, especially in pathological grounds. So we can only apply what is known about prevention of vascular disease in general since there is no supportive work on specifically preventive measures for vascular dementia .

Thank you for your comment Mr Gabrielli. I have grasped this indication that currently no cure but contributing factors of stroke such as hypertension can be managed by medical, social and physical prescription to avoid further deterioration in the hope of keeping VaD at bay. This is my first investigation of demetia and I m grateful for all the kind words. Thank you all .
