Chant-like (or syllabic) speech: another characteristic of speech disorders in the presence of damage to the cerebellar system. It is due to an abnormal configuration of stress during speech and is evenly separated into many disjointed phases of speech. It resembles the iambic pentameter of reciting old poetry. Chant-like speech is most often seen in cerebellar earthworm damage and cerebellar degenerative disorders. In multiple sclerosis, 10% to 15% of patients have this type of dysarthria and chant-like speech. Cerebellar damage The cerebellum is the largest part of the hindbrain and the second largest organ in the central nervous system after the brain. It is slightly oval in shape and is located on the dorsal side of the pons and medulla oblongata, with a cavity between the three, the fourth ventricle. The middle part of the cerebellum is narrow and is called the cerebellar earthworm. Visually, there is a longitudinal narrow part in the middle of the cerebellum, curled like a worm, called the earthworm part. The cerebellum regulates somatic movements and, together with the vestibular nucleus and red nucleus, regulates muscle tension and somatic reflex activity. Multiple Sclerosis Multiple sclerosis is an inflammatory and demyelinating disease of the central nervous system and immune system. In fact, nerve fibers, neurons and oligodendritic cells are also damaged. Multiple sclerosis is the most common disease in young people that causes neurological disorders other than trauma. To date, the cause of MS remains unknown. It is assumed that there are a number of triggers that cause attacks. Viral infections are the most well known, and some reports suggest a bacterial link. Pediatric multiple sclerosis Multiple sclerosis is an autoimmune demyelinating disease that involves the white matter of the central nervous system and is characterized by a disseminated, multifocal, and often remitting and relapsing course. Due to the presence of multifocal demyelinating plaques in the brain and spinal cord, the disease often manifests clinically as dysfunction in multiple parts of the nervous system. Multiple sclerosis with uveitis Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system characterized by recurrent episodes of dysfunction and multi-regional involvement. The disease can cause ocular abnormalities such as optic neuritis, uveitis, and extraocular myelopathy.
