I've seen an endocrinologist and he confirmed my problems are due to Risperdal.

Basal Ganglia damage cannot be diagnosed because there are no tests that could monitor the chemical imbalance of the brain.

I've come to the conclusion that my Basal Ganglia are damaged after knowing Risperdal affects them and they control learning, emotions, cognition and motivation, all of them have decreased after I took Risperdal so it's quite obvious my Basal Ganglia are damaged
