Hi Risperman, I didn't take Risperdal, but I know what it's like to have damage to the Basal Ganglia. My damage is in my hypothalamus gland. It's a very important part of the B.G. They can see a 5 mm lesion at the entrance to my pituitary stalk, but the neurosurgeon wouldn't tell me about it, so he said, "Your MRI results aren't back yet, but I'm sure you didn't have a stroke." I had an adverse reaction to an RX drug, called Gabapentin / Neurontin. Back to your question. Can they repair the Basal Ganglia? I really don't think so. Maybe time will slowly fix your problems, by rewiring. These stupid drugs can cause more harm than good. Sorry about your problems.
