The relationship between MMPI cluster membership and diagnostic category in headache patients.

Only one study has examined MMPI cluster profiles in the headache population. The present study expanded on this previous investigation by using a large sample size (N = 485) and a greater number of diagnostic categories. The five MMPI clusters replicated previous findings in the chronic pain literature. These MMPI cluster groups were compared to 5 diagnostic categories (migraine, cluster, post-trauma, tension, mixed). No relationship was found between cluster type and headache diagnosis. While the diagnostic groups were found to differ on measures of pain severity, sex and age, cluster groups did not. It is proposed that MMPI scale types reflect a patient's response to pain and are more likely to be the result of coping resources than headache-related personality style. Future research with additional, non-pain populations and prospective studies is suggested.

The vascular "cold patch" is not a prognostic index for headache.

Our previous research has determined that the vascular "cold patch" is a valid diagnostic "marker" and is a persistent constituent of the thermal geography of the external carotid region. It has been suggested by Dalla Volta and Anzola (1988) that the cold patch may be a prognostic index of vascular headache physiology; that is, as headaches improve through the use of vasoactive prophylactic medication, the cold patch would decrease in size or disappear. The purpose of this study is an attempt to replicate these findings. Forty migraine patients were randomly selected, and a thermographic re-examination of the external carotid region (forehead) was conducted. The post-treatment thermogram was then compared to the initial pre-treatment thermogram. Thirty subjects demonstrated an improved condition (IC) and ten subjects a worsened condition (WC). The IC Group exhibited a 73.2% reduction in headache frequency following a mean treatment period of 6.3 months. The WC Group demonstrated a 48.1% increase in headache occurrence at a mean treatment interval of fifteen months. Results demonstrated little thermographic difference between the two conditions. Within the IC Group, 46.7% of subjects exhibited and increase in cold patch size with an improved condition, 40% of cold patches remained stable, 6.7% of cold patches reduced in size, and zero cold patches disappeared with successful treatment. Within the WC Group, 20% of cold patches decreased in size with a worsened condition, 40% increased in size, and 40% remained stable. Chi square analysis determined there was no significant difference in cold patch changes between patients whose headache condition improved or worsened (p less than .70).(ABSTRACT TRUNCATED AT 250 WORDS)
