Mom is 81 and 8 months ago she had a bad car accident, since then I noticed within weeks a slight difference in her memory but she had a concussion stayed overnight at hospital I thought it was normal- 2 months later went to primary, memory test she was ok. I m with my mom daily & her memory loss has been sudden & is worsening. Just saw primary 1 mos ago, now going to Memory Specialist. She also has confusion, some hair loss, agitation, and fluctuating emotions... But memory loss is the worse. Could this be a Tramatic Brain Injury or more likely Alztheimers due to her age?
