Stop in for a cup of coffee

I been fighting with some short term memory issues and some cognitive abilities since my M/C wreck. Like sometimes you have to tell me twice for it to register, and sometimes I just forget wtf I'm doing in the middle of it. My right arm is still not 100%. I had nerve damage in my upper arm, but they're telling me the signals from my brain to right arm could be the problem.
yikes - are they saying sucks to be you or is there something that can be done?
