To further complicate the discussion, antipsychotics can actually CAUSE stuttering; it is considered a form of Tardive dyskinesia. I recently developed this condition along with some of the more stereotypical symptoms of TD (tremors, facial movements). I was interested in the mention of the significance of the types of dopamine receptors. It seems that might influence how antipsychotics affect stuttering. My doctor is decreasing my dose and I’m praying it resolves. The pharmacist said only half of cases resolve.
