I also have brain atrophy, just diagnosed accidentilly by CT scaqn when I went to immediate care because of an extreme headache in September 2023, I still have not seen a neurologist and don't have appt until late August, 2024 My PCP says it can either be mental or physical problem [or both] Have searched the internet to try to see what to expect. The literature I have found leads me to think it might be Parkinson's. Although, none of them mentioned brain atrophy. I have had falls for many years and I am 88 yr old, live alone. I am anxious to get a diagnosis, since I think the brain atrophy is just a symptom. Anyone else out there waiting in limbo to get into a neurologist.
