Methods
Clinical records of 89 patients accessing from January 2014 to April 2014 to our headache centre were reviewed and 27 MOH patients (2 males; 25 females) from 23 to 66 years old aged (M=40.63; DS=10.21) records were selected; demographical, clinical and psycho-social information were retrieved. Frequencies and covariance analyses were performed.
Results
MOH prevalence is 30.33%; migraine monthly frequency is high (M=16.74; DS=6.09); familiarity rate is 55.56%; comorbidity rate is 77.78%; most prevalent comorbidities are psychopathological (51.85%; mood disorders 25.93%; anxiety disorders 18.52%) and metabolical (22.22%); MIDAS mean score is 42.37; Zung-A mean score is 47.41; Zung-D mean score is 46.00; Prevalent personality traits are: evitating (25.93%) and obsessive-compulsive (18.52%);Self efficacy is predominantly low to middle (mode: sometimes); Overused medication are prevalently NSAID (59.26%) and combination analgesics (29.63%) with a average medications usage of 5397,04 mg/month and a mean overuse duration of 63.63 months; migraine frequency negatively correlates with age (p<0.05) and positively correlates with anxiety (p<0.01), depression (p<0.05), overuse (p<0.05); and disability level (p<0.05). Medication overuse positively correlates with disability (p<0.05).
Conclusions
The study suggest a relationship between medication overuse, health problems comorbidity and psychological aspects such as personality traits, self efficacy cognitions, psychopathological syndromes and disability.
