Hello and thanks for your query. I shall make an effort to provide you with good professional recommendations specific to your questions. There are a number of treatments for adult stuttering. Speech therapy can help adults that stutter, but is often dependant on a number of factors including the severity of the stammer, the commitment of the individual, the skills of the therapist, the underlying psychological issues of the individual. No single treatment is effective for every stammerer and because everyone is different some treatments need to be tailored to the individual. In some cases the stammer will completely disappear, but at some point in the future an event may cause the stammer to recur. I advice you to see therapist specialises in stammering. If possible, see a specialist who works regularly with stammering and keeps up to date with the latest approaches to therapy. Yet again, I duly appreciate your query to me, I do hope that have found something useful to help you and I shall be glad to answer any further apprehensions. Sincerely,
