ok first of all im 27 years old. i have been having some issues. once in awhile ill be driving down the road that i know and i will suddenly forget where i am. other things that have been happening is i sometimes forget words and i have a hard time spelling and i am usually pretty good at spelling. another thing i have been experiencing is hard to explain. when i walk down a set of stairs i almost miss one and almost fall, its weird and hard to explain. its almost like my depth perception is off but only when im going down stairs. i dont know what is wrong with me but something is not right...any ideas?
