Stuttering, a condition in which the normal pattern, rhythm, or timing of speech is disrupted, may be characterized by repetition and prolongation of words, phrases, and sounds, as well as hesitations or pauses that interrupt speech flow. Causes may be developmental (occurring in childhood), neurogenic (eg, head injury, stroke), or psychogenic (related to emotional trauma or stress). Because mild stuttering is often self-limiting, it is rarely treated. Patients with more severe forms often require speech therapy and counseling. Pharmacological therapy has produced inconsistent results or has been limited by side effects.It has been suggested that an antidopami-nergic effect may be beneficial in reversing stuttering problems. Risperidone, an antipsychotic approved for various psychiatric disorders, has broad neu-rotransmitter activity including antidopaminergic action and may be useful in resolving stuttering.
