Hello Charleigh,
Welcome to the NeuroTalk Support Groups.

There are few posts that I can find across the forums here relating to Ganglioglioma apart
from this thread but you could try posting in the
General Health Conditions and Rare Disorders Forum

There may be members there who can help you with questions about your son's recovery post surgery.

The members on the
Traumatic Brain Injury and PCS Forum
may also have some ideas even though not specifically related to Ganglioglioma.

There is also the forum search feature

All the best to him and to you.
