Hi, Contact a Certified Speech language Pathologist/Speech Therapist Stuttering is usually diagnosed by a speech-language pathologist (SLP), a health professional who is trained to test and treat individuals with voice, speech, and language disorders. The speech-language pathologist will consider a variety of factors, including the case history (such as when the stuttering was first noticed and under what circumstances), an analysis of the stuttering behaviors, and an evaluation of the speech and language abilities and the impact of stuttering on his or her life. The current therapies for teens and adults who stutter focus on learning ways to minimize stuttering when they speak, such as by speaking more slowly, regulating their breathing, or gradually progressing from single-syllable responses to longer words and more complex sentences.For this kind of therapy Speech language Pathologist are the trained professionals. Drug therapy The U.S. Food and Drug Administration (FDA) has not approved any drug for the treatment of stuttering. However, some drugs that are approved to treat other health problems—such as epilepsy, anxiety, or depression—have been used to treat stuttering. These drugs often have side effects that make them difficult to use over a long period of time. In a recent study funded by the National Institute on Deafness and Other Communication Disorders (NIDCD), researchers concluded that drug therapy has been largely ineffective in controlling stuttering. Clinical trials of other possible drug treatments are currently under way. Sanjay Kumar B.Sc. (Hons.) Speech and Hearing, AIIMS New Delhi M.Sc.
