What Causes Stuttering?

Brain Injuries

When some sort of brain injury causes stuttering, it is considered to be neurogenic stuttering. Neurogenic stuttering can be associated with many different types of brain injuries including those caused by strokes, head trauma, tumors and cysts, degenerative diseases, or drug-related side effects. Stuttering usually occurs as a result of injury or degeneration to certain areas of the brain or spinal cord, such as the cortex, subcortex, cerebellar, or neural pathways. Stuttering caused from brain injuries can be described as fragmented, slow, and with great effort, placed into producing sounds and words. Because of the association with many types of diseases and injury, stuttering may produce many different symptoms and be unique to the individual.
