Tension type headache: a neuropsychological and neurophysiological study

Characteristic personality profiles of patients suffering from either migraine headache (MH) or tension type headache (TTH) have been described in the light of Minnesota Multiphasic Personality Inventory (MMPI). In the present study we evaluated personality profile changes following modifications of the painful symtoms after treatment, through the administration of the MMPI to MH and TTH patients. In TTH patients with no clinical improvement the depression scale scores were higher after 6 months of treatment, whereas in MH patients similar scores were observed before and after therapy, thus suggesting a primary role of depression in the onset of pain in the latter patients. Computerized EMG recording of the neck muscle activity showed different patterns of muscle contraction in resting condition and during stress or maximal muscular activity in patients suffering from TTH as compared to MH patients and normal subjects
