I have some problem related to my brain..like at times i got fainted and start behaving abnormally and for 15-20 minutes i stay totally blank. Usually i face this problem when i wake up in the morning or when i close my eyes for few seconds. Done with all scans related to brain but reports show nothing. Now one report showed that i have thyroid problem having high tsh level than normal. So i want to know that is thyroid the reason for mental illness. Consulted so many doctors but nothing works.
