What is the difference between seizure attack and panic attack. What do we call if someone gets sudden feeling of fear. Losing concentration. Becoming very sluggish. Unable to think logically. Mind goes blank. Unable to have restful sleep. Sudden change in appearance and behaviour and you will have this condition suddenly without any reason and whenever it happens others able to identify easily and by taking tablet at that time will make you normal again within couple of minutes. And no idea when it will reoccur again. What is it? why it happens and what to do to not to happen? Please advise.
