My thesis is about how Brain Fag Syndrome affects undergraduate students in Nigeria, if Brain Fag Syndrome was prevalent and if there are factors associated with it. i also talked about the history of Brain Fag Syndrome and other peoples interpretation of this syndrome. I also established the genesis of Brain Fag Syndrome. Finally a survey was taken to determine if Brain Fag Syndrome was present in Ebony state University and Federal University of Technology Owerri, both of them in Southeast of Nigeria and if Brain Fag Syndrome affected the performance of students in this University.
