Evaluation of cognitive functions in migraineurs treated with topiramate

Topiramate for the treatment of migraine prophylaxis may cause side effects such as cognitive dysfunction. We aimed to investigate the topiramate's efficacy in migraineours and effect on cognitive functions. 24 migraine patients (Group 1) and 24 healthy participants (Group 2) were included. In both groups event -related potentials P300 Latency, Amplitude and N200 Latency, Amplitude's were evaluated. Topiramate treatment was ordered to group 1. Two months after treatment, the same parameters were evaluated. Monthly number of attacks, painful days, analgesic-triptan use and VAS scores were compared before and 2 months after treatment. Evaluation between group 1 and group 2 showed no difference. Groupl's before and after treatment values were compared; all parameters after treatment were statistically significantly better. Group 1's number of attacks in a month, the number of painful days in a month, VAS score, the number of analgesic use, the number of triptan use had all decreased after treatment. 100 mg topiramate was effective in the treatment of migraine. However, electrophysiological studies showed that cognitive functions are also affected adversely. (C) 2018 Elsevier Ltd. All rights reserved.
