Answer

Vascular dementia is the second most common form of dementia after Alzheimer Disease (AD). The condition is not a single disease; it is a group of syndromes relating to different vascular mechanisms. As early as 1899, arteriosclerosis and senile dementia were described as different syndromes. In 1969, Mayer-Gross et al described this syndrome and reported that hypertension is the cause in approximately 50% of patients. Patients who have had a stroke are at increased risk for vascular dementia. In 1974, Hachinski et al coined the term multi-infarct dementia. In 1985, Loeb used the broader term vascular dementia. Recently, Bowler and Hachinski introduced a new term, vascular cognitive impairment. Vascular dementia is preventable; therefore, early detection and an accurate diagnosis are important.
