my 80 year old mother fell about 3 months ago and hit her head on cement and had a black eye and it looked black and blue for a month or 2. she has not been acting right since she fell. she had a scan of of her head and was normal. she is now having headaches on the side she sit and that eye is giving her problems. she is dizzy, balance off, tired and depressed. she is normally a go getter. what should i do?
