The most common types of stuttering include developmental stuttering, acquired (or secondary) stuttering, and psychogenic stuttering. Developmental stuttering is typically diagnosed in children between the ages of two and six years old. Acquired or secondary stuttering can occur at any age but tends to be more common among adults who have experienced a traumatic event such as a car accident, surgery, or other life-changing events. Psychogenic stuttering is caused by an emotional disturbance that results in involuntary repetitions or blocks in speech.
