I am new to this forum and I am hoping someone may be able to help me. My son (20yo) suffered a very severe concussion last May. He was not hospitalised but in hind sight should have been. He suffered amnesia for about 3 weeks and headaches and confusion. Upon investigation CT scans and EEG and other scans, it was found there was no bleeding or fractures etc. Since then, his memory has been getting worse and to the effect that sometimes he cannot remember a hour before what he was doing or who he saw. He is otherwise fit and healthy. He is still studying university which is a concern in itself. At the time of the accident, he ceased uni for about 7 weeks to recover and did not drive a vehicle for about 6 months under doctors advice. Has anyone else had a similar incident and if so, how long did the memory loss occur. We live in a small country area in NSW, Australia, if that helps anyone.
