My grandad is 80 and recently had a fall. He has been checked at the hospital- ecg, brain scans etc and everything was fine. A week after his fall he became confused. He didn't really understand who my Nan was and was agitated and couldn't sleep well. Its been 2 weeks and the confusion is still there. Its very random. He can be fine and then all of a sudden say something random. When he is confused he only confuses who my Nan is by saying things like "have you always lived here?" etc. He also randomly thinks he is not at home and talks about 'his new house.' Has anyone experienced anything similar? I am so anxious and worried. Could it be the shock of the fall?? He seems a bit depressive as he hasn't been able to drive etc and he is so used to nipping to the shops and doing jobs in the garden. Hoping someone somewhere can say they have experienced something similar after a fall.
