PARALYSIS

a chronic, usually fatal, disease, marked hy progre ive paralysis and atrophy of the muscles of the lips, tongue, mouth, pharynx, and larynx, and due to degeneration of the nerve nuclei of the floor of the fourth ventricle.

The disease occurs usually late in childhood, and is marked by various deformities, lordosis, and a peculiar swaying gait with the legs kept wide apart. The paralysis progre ively increases, ending in death, which is usually due to respiratory weakne . psychic Ῥ. Same as Aysteric p. reflex p., one ascribable to peripheral irritation.
