This study from May 2012 has this fascinating line;
"The study demonstrates that damage to the brain's vascular system may play a key role in Alzheimer's disease, and highlights growing recognition of potential links between stroke and Alzheimer's-type dementia," said Roderick Corriveau, Ph.D., a program director at NIH's National Institute of Neurological Disorders and Stroke (NINDS), which helped fund the research.

World-first: Australian researchers are investigating why some stroke victims slide into dementia.
In a world-first study, Australian researchers are investigating why one out of three stroke victims - even when they appear to make a good recovery - slide into dementia.
It takes two or three years for dementia symptoms to develop and the reasons have never been explained. Really?
Lead researcher Amy Brodtmann from the Florey Institute of Neuroscience and Mental Health said people had problems with thinking, speech and memory immediately after a stroke but ''usually recover''.
''What's happening down the track is some people, not everyone, are developing cognitive decline and some people are developing dementia,'' Dr Brodtmann said.
Over three years, they will undergo four MRI scans - taken upon recruitment, at three months, one year and three years - to measure any changes in the brain, including shrinkage. The results are correlated with evidence of memory and cognitive impairment.
Dr Brodtmann says that understanding these changes may give some clues as to how to predict which patients will suffer cognitive impairment and may be assisted by early intervention.
One aspect of brain degeneration being looked for are lesions in the white matter of the brain that have been strongly linked to a reduction in cognitive capacity.
Fifty people have already been recruited, including a pilot group that began their scans two years ago. Dr Brodtmann says these people seem to have undergone changes in the brain that are typical of patients with Alzheimer's disease without the dementia.
