Psychopathological profile of patients with chronic migraine and medication overuse: study and findings in 50 cases
- 214 Downloads
Patients with chronic migraine (CM) have high frequence of psychiatric comorbidity or psychological distress. The presence of depression, anxiety, panic or obsessive disorders in these patients contributes to poor quality of life and can influence prognosis and treatment. A systematic investigation of psychiatric comorbidity is needed in patients with CM especially in those with medication overuse (MO), in order to reach a more comprehensive clinical management. We assessed the psychological profile of 50 patients, 40 women and 10 men suffering from CM with MO. The Spectrum Project, a complementary way of describing and assessing psychopathology with structured clinical interviews, was used for the psychological evaluation of the patients to explore personality traits. Spectrum instruments mood disorders (MOODS), panic agoraphobic disorders (PAS) and obsessive–compulsive disorder (OBS) were applied to study patients. OBS-questionnaire was positive in 28% of the patients, MOODS-questionnaire in 44%, PAS-questionnaire in 46%. 19 on 50 patients (38%) presented positivity to 2 or to all questionnaires in variable associations. None of the patients of the studied group had complete normal findings in the questionnaires. Clinical records of patients with OBS-questionnaire positivity showed a worse clinical course and tendency to relapse. These results suggest that psychological assessment is an essential step in the evaluation and treatment of patients with CM and MO. The remarkable percentage of OBS-questionnaire positivity in this group indicates that obsessive–compulsive trait represents besides depression and anxiety, a major risk of chronification and overusing.
