Four main causes contribute to stuttering, including genetics, child development, neurophysical abnormalities and family issues, according to The Stuttering Foundation. A combination of these factors may cause stuttering, and the causes of stuttering may not be what makes the condition worsen later in life.
Sixty percent of people who stutter have a family member with the same condition. Developmental difficulties or speech abnormalities in children may contribute to stuttering. People with this condition may process speech differently in the brain. Children with fast-paced lifestyles, high expectations or dysfunctional family dynamics may develop a stuttering pattern, according to The Stuttering Foundation.
Mayo Clinic asserts language centers in the brain can be affected by genetics in stuttering patients. Timing, sensory and motor coordination abnormalities in the nervous system may also lead to stuttering. Emotional trauma or emotional distress can cause stuttering in rare cases. Medical conditions that affect the brain, such as stroke or trauma, may lead to loss of speech control.
The Stuttering Foundation explains a speech pathologist can help people who stutter by using speech therapy. Goals of therapy, length of time and amount of success are all factors that patients consider during the speech therapy process. An intensive speech therapy program for severe stuttering may include 40 hours of therapy over a three-week span.
