Dysarthria
Causes of Dysarthria
Dysarthria may be caused by damage to the following: Parts of the brain that control muscle movement. Cerebellum : The cerebellum, which is located between the cerebrum and brain stem, coordinates the body’s movements. Basal ganglia: These large collections of nerve cells help coordinate and smooth out movements (see figure Locating the Basal Ganglia ). Brain stem : The brain stem controls the muscles that are used in breathing and those used to help make sounds. The nerve fibers that connect the outer layer of the cerebrum (cerebral cortex) to the brain stem: These nerve fibers relay information needed to control and coordinate the muscles used to produce speech, including muscles of the lips, tongue, palate, and vocal cords. Overview of Neuromuscular Junction Disorders : Nerves connect with muscles at the neuromuscular junction. These structures can be damaged by degenerative disorders (such as Amyotrophic Lateral Sclerosis (ALS) and Other Motor Neuron Diseases (MNDs) ,
