Hello. My husband had a fall onto his head from about 10 feet in January of 2013. He was quite badly concussed, but was not knocked out. He hit at the back of his head, and the force of the fall burst his head open at the top...it was quite a blow. They never did any scans, they just stitched him up (it required two layers of stitches as it burst right to the skull. He was concussed quite badly for 10 days and was "normal" again after three weeks but after that he developed depression. He started to have problems sleeping, was irritable, less motivated. We had a very, very stressful year and in November 2013 he had a complete breakdown, after which he has been very deeply depressed. So much so that he left our family and lives on his own. He started Citalopram three weeks ago for the depression, and has started counselling. However, his behavior is often strange. He has turned very heartless and mean, where he was very kind before. He feels no emotions. He is sometimes hyper and says inappropriate things and has worrying memory problems and confusion (forgetting the day of the week and going to the wrong appointments). He is ike a stranger really. His doctor says it is just depressions but I am concerned there is some link to the head injury. Should he insist on a scan or seeing a specialist? Or is it more likely there is no link and he is just depressed due to the extreme stress he has experienced recently?
