Relation Between Headaches and Neuropsychological Functioning Among Head Injury Patients


William T. Tsushima, Ph.D., Straub Clinic and Hospital, 888 South King Street, Honolulu, HI 96813



The Luria-Nebraska Neuropsychological Battery (LNNB) and the Minnesota Multiphasic Personality Inventory (MMPI) were administered to 184 head injury patients with varying degrees of headache activity. A multiple regression analysis, controlling for neurological status, compared the 11 LNNB scores ofpatients with Daily Headache, Frequent Headaches, Infrequent Headaches, and No Headaches and foundthat the Arithmetic Scale was the only significant predictor, with the Daily Headache patients performing more poorly than the Infrequent Headache patients. A similar analysis of the 13 MMPI scores indicated that the K, He, and Pt Scales were significant predictors. However, post hoc Tukey tests revealed that K and Pt scores did not vary significantly among the four headache groups and only showed that Daily Headaches and Frequent Headaches patients had significantly higher Hs scores than the No headaches group. Subsequent comparisons of patients with and without headaches at the time of testing revealed no differences between the two groups on the LNNB and MMPI, after controlling for age, duration of symptoms, and neurological status. Overall, the results suggested that the relation between headache symptoms and neuropsychological functioning was insignificant.
