Modified Hachinski Ischemic Scale-NACC Version Questionnaire

**Semantic type:** Intellectual Product

**Definition:** A standardized rating scale originally developed by Hachinski et al in 1975 and later modified by Rosen et al in 1980 to clinically differentiate two most common types of dementia: senile dementia of the Alzheimer type (SDAT), a primary degenerative disease, and primary degenerative disease (MID), a vascular disorder. The modified version of the questionnaire contains 8 features for more accurate diagnosis of MID, the vascular dementia type. This questionnaire can be scored between 0 and 18, where a score greater than 7 suggests vascular involvement.
