Sure. Here's a randomized, placebo controlled, clinical trial on risperidone in the treatment for developmental stuttering. The key findings were statistically significant improvements in fluency in those who received risperidone versus placebo after 6 weeks. Most saw improvements at 0.5mg, while others saw improvements at higher doses. Finally, risperidone was well tolerated by the participants. https://pubmed.ncbi.nlm.nih.gov/10917410/ We're done here - but you'll try and extend the goal post because youre blatantly dishonest.
