Personality traits in chronic daily headache patients with and without psychiatric comorbidity: an observational study in a tertiary care headache center.

BACKGROUND: Previous studies suggest that patients with Chronic Daily Headache (CDH) have higher levels of anxiety and depressive disorders than patients with episodic migraine or tension-type headache. However, no study has considered the presence of psychiatric comorbidity in the analysis of personality traits. The aim of this study is to investigate the prevalence of psychiatric comorbidity and specific personality traits in CDH patients, exploring if specific personality traits are associated to headache itself or to the psychiatric comorbidity associated with headache. METHODS: An observational, cross-sectional study. Ninety-four CDH patients with and without medication overuse were included in the study and assessed by clinical psychiatric interview and Mini International Neuropsychiatric Interview (M.I.N.I.) as diagnostic tools. Minnesota Multiphasic Personality Inventory-2 (MMPI-2), Hamilton Depression Rating Scale (HAM-D) were afterwards administered. Patients with and without psychiatric comorbidity were compared. Further analyses were made by splitting the whole group according to the headache diagnosis and the presence or not of medication overuse. RESULTS: Psychiatric comorbidity was detected in 44 patients (46.8%) (group A) and was absent in the remaining 50 patients (53.2%) (group B). Mood and anxiety disorders were the most frequently diagnosed (43.6%).In the overall group, mean scores of MMPI-2 showed a high level in the so-called neurotic triad; in particular the mean score in the Hypochondriasis subscale was in the pathologic area (73.55 ± 13.59), while Depression and Hysteria scores were moderate but not severe (62.53 and 61.61, respectively). In content scales, score in Health Concern was also high (66.73).Group A presented higher scores compared to Group B in the following MMPI-2 subscales: Hypochondriasis (p= .036), Depression (p= .032), Hysteria (p< .0001), Hypomania (p= .030). Group B had a high score only in the Hypochondriasis subscale. No significant differences were found between chronic migraine (CM)-probable CM (pCM) plus probable medication overuse headache (pMOH) and chronic tension-type headache (CTTH)-probable CTTH (pCTTH) plus pMOH patients or between patients with and without drug overuse. CONCLUSIONS: The so-called "Neurotic Profile" reached clinical level only in CDH patients with psychiatric comorbidity while a high concern about their general health status was a common feature in all CDH patients.

Metabolic risk factor profile associated with use of second generation antipsychotics: a cross sectional study in a Community Mental Health Centre.

BACKGROUND: Second generation antipsychotics (SGA) have demonstrated several advantages over first generation antipsychotics (FGA) in terms of positive, negative, cognitive, and affective symptoms and a lower propensity for extrapyramidal side effects. Despite these undeniable advantages, SGA have been associated with causing and exacerbating metabolic disorders, such as obesity, diabetes, and hyperlipidemia. This cross sectional study aimed to evaluate the metabolic risk factor profile associated with use of SGAs in comparison with non -treated control patients. METHODS: The study was carried out at a Community Mental Health Centre (CMHC) in Bologna. The study subjects were outpatients with serious mental disorders treated with SGA (clozapine, olanzapine, risperidone, quetiapine). A sample of adult men and women suffering from idiopathic hyperhydrosis, without psychiatric history or antipsychotic treatment, were randomly selected from outpatients of the Department of Neurology in Bologna as a reference group. We investigated differences among the treatment and reference groups for glycaemia, cholesterolaemia and triglyceridaemia levels. RESULTS: The study sample was composed of 76 patients, 38 males and 38 females. The reference group was composed of 36 subjects, 19 females and 17 males. All patients treated with SGAs had higher mean glycaemia and triglyceridaemia and a significantly higher risk of receiving a diagnosis of hyperglycaemia and hypertriglyceridaemia than the reference group. We did not find any differences in mean glycaemia or mean triglyceridaemia levels among treatment groups. Patients with clozapine had a significantly higher mean BMI value and rate of obesity than patients treated with other SGAs. CONCLUSION: The rate of obesity and metabolic disorders observed in this study were higher than the prevalence in the control group and similar to that previously reported in psychiatric samples; these findings imply per se that more attention should be paid to the metabolic condition of psychiatric patients. In line with the International Consensus Conferences we recommend that monitoring of weight, fasting plasma glucose, cholesterol and triglyceride levels be obtained in routine clinical practice with all antipsychotics.
