Good for you! Like I’ve been saying in all my posts, it’s roots is a neurological condition. Risperidone essentially modulates dopamine and seratonin in the brain. By reducing dopamine overactivity, risperidone helps stabilize neural firing patterns involved in speech initiation and timing etc… It was originally developed to treat schizophrenia and bipolar disorder, but has seen to have positive effects on improving fluency for stutterers too.
