The construct validity of the ischemic score of Hachinski for the detection of dementias

J Neuropsychiatry Clin Neurosci. 1989 Spring;1(2):181-7. doi: 10.1176/jnp.1.2.181.


Two hundred forty-one nursing home patients from the National Nursing Home Survey Pretest were assessed using the Ischemic Score of Hachinski. Medical chart diagnoses were used to classify those with and without dementia. The Mini-Mental State Examination was used to assess the accuracy of the medical-chart diagnoses of dementia. The Ischemic Score failed to differentiate multi-infarct dementia from other types of dementias. Instead, the difference between the two dementia groups was in the direction opposite that predicted by Hachinski.
