Several studies have shown the presence of a comorbidity between migraine and vascular diseases, like hypertension and stroke. The mechanisms of this comorbidity are unknown. Impaired insulin sensitivity has recently emerged as a risk factor for hypertension and stroke. We evaluated insulin sensitivity in 30 young, nonobese, nondiabetic, normotensive migraine patients and in 15 healthy controls. During the OGTT, glucose plasma concentrations were significantly higher in migraineurs than in controls. Insulin sensitivity, as measured by ISI-stumvoll and OGIS-180 indexes, was significantly altered in migraine. Our data show that insulin sensitivity is impaired in migraine and suggest a role for insulin resistance in the comorbidity between migraine and vascular diseases.
The objective was to evaluate the prevalence and the characteristics of anger and emotional distress in migraine and tension– type headache patients. Two hundred and one headache patients attending the Headache Center of the University of Turin were selected for the study and divided into 5 groups: (1) migraine, (2) episodic tension–type headache, (3) chronic tension–type headache, (4) migraine associated with episodic tension–type headache and (5) migraine associated with chronic tension–type headache. A group of 45 healthy subjects served as controls. All the subjects completed the State–Trait Anger Expression Inventory, the Beck's Depression Inventory and the Cognitive Behavioral Assessment. Anger control was significantly lower in all headache patients ( p <0.05) except in migraineurs. Patients with migraine and tension–type headache showed a significantly higher level of angry temperament and angry reaction ( p <0.05). In addition, chronic tension–type headache and migraine associated with tension–type headache patients reported a higher level of anxiety ( p <0.05), depression ( p <0.001), phobias ( p <0.001) and obsessive–compulsive symptoms ( p <0.01), emotional liability ( p <0.001) and psychophysiological disorders ( p <0.001). Our study shows that chronic tension–type headache and migraine associated with tension–type headache patients present a significant impairment of anger control and suggests a connection between anger and the duration of headache experience.
Background: Migraine without aura causes acute and chronic pain and partially compromises patients’ social functioning and work performance. Over the past years, psychiatric comorbidities were frequently observed in these patients, together with coping difficulties and typical personality traits. The aim of this study was to identify whether migraine patients and controls share distinctive personality traits. Methods: 105 consecutive patients suffering from migraine without aura referred to the Headache Center of Turin University were enrolled in the study and compared to a control group of 79 healthy subjects. Patients and controls completed several psychometric questionnaires, including the Temperament and Character Inventory, the Beck Depression Inventory and the State-Trait Anger Expression Inventory. Results: Patients suffering from migraine show more depressive symptoms, difficult anger management with a tendency to hypercontrol, and a distinctive personality profile with high harm avoidance, high persistence and low self-directedness. When a logistic regression was performed, the only significant predictors of migraine were temperament variables. Conclusions: The results suggest that the personality traits and psychosomatic mechanisms of migraine patients may make them vulnerable to stress and less skilled in coping with pain. These traits correlate with dysregulated neurotransmitter systems which may also be part of the psychobiological components of personality, depressive disorders and migraine itself.
Recent studies suggested that genetic factors play a role in cluster headache (CH). However, the type and the number of genes involved in the disease are still unclear. We performed an association study in a cohort of Italian CH patients to evaluate whether a particular allele or genotype of the Clock gene would modify the occurrence and the clinical features of the disease. One hundred and seven CH patients, diagnosed according to the International Classification of Headache Disorders, 2nd Edition, (ICHD-II) criteria, and 210 healthy age, sex and ethnicity-matched controls were genotyped for the 3092 T-->C Clock gene polymorphism (also known as 3111 T-->C). Phenotype and allele frequencies were similarly distributed in CH patients and controls. The clinical features of the disease were not significantly influenced by different genotypes. In conclusion, our study suggests that the 3092 T-->C polymorphism of the Clock gene is unlikely to play an important role in cluster headache.
The therapy of headache attributed to spontaneous low CSF pressure (previously defined as spontaneous intracranial hypotension) is still a matter of debate. Epidural blood patch is considered the most effective treatment. However, pharmacological strategies may be considered before blood patch. We report three patients with headache attributed to spontaneous low CSF pressure that were successfully treated with oral prednisone. Additional studies may be useful to prove the effectiveness of corticosteroids in this syndrome.
