She is 89 and has had dimentia for 9yrs. Recent drs visit -All bloodwork is good, cat scan showed no stroke. Has been given meds for alergies, puts her to sleep but itching and crying come back the next day. Every cream and powder has been used. She takes antidepressant but had a bad reaction to higher dose. She didn't cry or itch on higher dose, but hallucinated, had tremors and trouble walking. This seems to be a problem with her neurological system. I don't know what else to try. Is this something she is going to have to just live with ? Might a neurologist be able to help?
