Welcome to Connect, @chiefsfan75
I'd like to introduce you to @lisapraska, whose son was also diagnosed with Cerebral Brain Atrophy and ultimately with White-Sutton syndrome. In addition to this discussion , you may be interested in reading more in these discussions on Connect to help prepare questions for your appointment tomorrow.
- White-Sutton syndrome https://connect.mayoclinic.org/discussion/white-sutton-syndrome/
- Cerebral Brain Atrophy https://connect.mayoclinic.org/discussion/cerebral-brain-atrophy-yet/

Chiefsfan, will you be accompanying your granddaughter to the appointment as a second set of ears for her parents?
