The curability of stuttering is a complex and debated issue. Some people who stutter may experience a spontaneous remission, where their stuttering resolves on its own, typically in the early childhood years. However, for many people, stuttering is a chronic condition that requires ongoing treatment.

While there is no known cure for stuttering, treatment can help people who stutter to speak more fluently and confidently. With the right support and interventions, people who stutter can learn to manage their condition and improve their quality of life.

It is important to note that the effectiveness of treatment for stuttering can vary depending on a number of factors, including the severity of the stuttering, the person's age and individual characteristics, and the type of treatment they receive. A qualified speech-language therapist can provide more information about the potential for improvement in stuttering and help develop a treatment plan that is tailored to the person's specific needs and goals.
