People with vascular dementia present with progressive cognitive impairment, acutely or sub-acutely as in mild cognitive impairment, frequently step-wise, after multiple strokes. [5] The disease is described as both a mental and behavioral disorder within the ICD-11. [8]
A microinfarct is a microscopic stroke generally ranging between 0.1 millimeter and 1 millimeter in size. [1] [2] Microinfarcts can be found in 25-50% of all elderly deceased persons. Microinfarcts may be the second most important cause of dementia, after Alzheimer's disease. [3] [4]
Because of this, the specific names of these types of this dementia, including Binswanger's disease were lost. [4] This was until 1992 when Alzheimer's diagnostic centers created specific criteria known as the Hachinski Ischemic Scale (after Dr. Vladimir Hachinski) which became the standard for diagnosing MID or vascular dementia.

Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
Brain scans may show evidence of multiple strokes of different sizes in various locations. People with vascular dementia tend to have risk factors for disease of the blood vessels, such as tobacco use, high blood pressure, atrial fibrillation, high cholesterol, diabetes, or other signs of vascular disease such as a previous heart attack or angina.
