ABSTRACT
@#Background & Objectives: According to ICHD-III beta 2013 criteria, chronic migraine is defined as having headaches more than 15 times a month, for a period of more than 3 months, at least 8 must have migrainous features or good response to migraine-specific treatment; there must also be a history of 5 or more migraine attacks. The aim of the present study was to evaluate the effect of Botulinum Neurotoxin A (BONT/A) on headache and daily activities in chronic migraine patients using VAS, MIDAS and HIT-6 tests. Methods: Twenty five patients admitted to Hospital Department of Neurology were reviewed retrospectively. In order to evaluate the severity of headache and effects on daily performance, MIDAS (Migraine Disability Assessment Test), VAS (Visual Analogue Scale for Pain) and HIT-6 results after the baseline assessment, first and second administration of (BONT/A) were examined retrospectively from patients’ records. Results: VAS, MIDAS and HIT-6 scores were compared after baseline assessment and the first and second administrations. Results showed that VAS, MIDAS and HIT-6 scores decreased. This difference was statistically significant (p<0.05). Correlation analysis was conducted and significant correlations between scores on these three tests were found.Conclusions: The results showed that BoNT/A is an important and effective treatment option for chronic migraine patients not responding to migraine-specific prophylactic treatment and having alterations in daily life due to frequency and severity of pain.
