Six weeks is just a short time for recovery for PCS issues. I'm going on 4 months and while my symptoms have lessened, the one thing that I don't tolerate all that well is alot of noise. So I can empathize with what you mom is going through.

If I am thrown into a noisy situation (crying babies, loud music, loud chatter) I don't do well the next day. It's just still too much stimulation for my healing brain. I go back to having pressure headaches, feeling anxious and irritable...so I just go back to bed. I just purchased some earplugs and noise cancelling headphones, so I'll have to let you know how those work.

In the future, perhaps your mom can use some earplugs and see if that helps her when she is going into noisy situations.

Your mom is lucky to have your support. PS: your father needs to read up on the TBI Guide as well as your mom and hopefully, he will understand what she is going through.
