Body Llais syndrome is a neurological disease characterized by atrophy of the muscles of the trunk and limbs, as well as impaired balance and coordination of movements. In modern medicine, the term “hemiballis” is used in relation to this syndrome. The disease is rare - only 4% of patients with various injuries to the nervous system.
Often, the development of Llais syndrome is associated with the consequences of injuries to the spinal cord or other parts of the central nervous system, which are accompanied by inflammation, hemorrhage, and sometimes damage to brain structures. The basis of the disease is the rapid degeneration of motor cells of the anterior horns of the lateral horns of the spinal cord and the anterior pons nucleus. In addition to disorders in the brain, the cerebellum suffers, coordination of movements is impaired, the functioning of the musculoskeletal system is disrupted, difficulty performing movements, and muscle weakness appear. Patients with the syndrome may experience sudden falls, stumbles, and loss of balance. Their movements often look awkward. Typically, such people can only move within one room; they coordinate their movements much less well outside its walls. Suprascapular pain, symptoms of radiculopathy, tensor muscle disorders, brain insufficiency of the lower extremities, blurred vision, paralysis of the soft tissues of the face and eyes, and anemia may occur. Heart and lung problems may occur.
