The data was collected using a predesigned and pretested questionnaire. Detailed history like name,age,sex,residence were noted.Routine clinical examination was performed.Rinne’s ,weber and pure tone audiometry was conducted.Following the BERA was done by using ‘Neruoperfect EMG-2000(EMG/Ncv/EP) System. The collected data will be entered in the MS excel sheet Windows 10.The analysis was done using SPSS 23.Conclusion:Our study concludes that there is involvement of brainstem in the migraine patients.The auditory brainstem evoked responses can be used as an non invasive,reliable and diagnostic method .It also works an earliest indicator for the impeding auditory involvement in the migraine patients.
