This finding could eventually pave way for improved strategies to either treat or prevent dementia. Although previous studies have established that Alzheimer's disease and vascular dementia can account for a major proportion of all dementias, the exact reason for this association has been largely unknown.
The study consisted of 170 patients, consisting of Alzheimer's disease (50%) and Vascular Dementia (50%). The frequency of occurrence of spontaneous cerebral emboli (blood clots in the brain) was noted in comparison to age-matched control group.
Alarmingly, spontaneous blood clots were found to be present in 37% of Vascular Dementia patients and 40% of patients with Alzheimer's, within just one hour of monitoring. This percentage was much lower than that observed in the control group.
This observation has led the researchers to conclude that spontaneous blood clots or cerebral emboli are closely associated with both the diseases. Clearly more study is needed further to better understand the association between the two.
