My relative who was diagnosed in July having surgery immediately has now had what we think was a small stroke showing stroke symptoms and signs on the opposite side of her tumor. She never had chemo and Rad. due to the fact that from the time she had her seizure – 4 days before the tumor removal she has not been herself. She now sleeps 18 hrs a day or more and is unable to use her left side. Has anyone else experienced that aspect of the GBM?
