Hachinski Ischemic Score
Definition: tool used in screening to differentiate vascular dementia from degenerative forms of the disorder. Patients with a score of 7 or higher are more likely to have a vascular dementia. A low Hachinski Ischemic Score is less likely to indicate vascular dementia because ischemic lesions severe enough to produce a dementia would be expected to be severe enough to cause the accompanying neurologic changes and elevate the Index.
