How do caregivers deal with occupation like this one, sometimes I have to deal with a person who has a concussion in the brain.

You mention in your profile that you are caring for a friend who was in a serious auto accident. Were there head injuries that caused difficult to deal with behaviors? Is this person violent, combative or downright dangerous? Are you a live-in caregiver? Are you trained as a CNA, STNA or LPN? Does this person also have dementia/Alzheimer’s?

You don’t say what your issues with this person are, but do you feel that you may be in over your head so to speak? Is there family, a caseworker or a doctor you could speak with? Maybe this friend needs to be evaluated.

What exactly is your question bettywhitfield? Lots of people of all ages have concussions, and I can't see how that relates to your topic choice of POA?
