What is tongue muscle atrophy? What are the symptoms?

Many people are unfamiliar with muscular atrophy, but many people know Hawking. Hawking suffers from Parkinson's disease, which is muscular atrophy. So what is tongue muscle atrophy like?

Muscular atrophy refers to skeletal muscle dystrophy, in which the muscle volume is smaller than normal, the muscle fibers become thinner or even disappear. Neuromuscular disease hypertrophy. In addition to the pathological changes in the muscle tissue itself, the nutritional status of the muscle is closely related to the nervous system. Spinal cord diseases often lead to muscular malnutrition and muscle atrophy.

Juvenile unilateral upper limb muscular atrophy occurs between the ages of fourteen and twenty-four, and is more common in males. The onset of muscle atrophy is insidious, manifested by thinning below the midpoint of the forearm, obvious atrophy of the thenar, hypothenar and interosseous muscles, often unilaterally, with clear atrophy boundaries, no sensory impairment, but more obvious autonomic nervous system impairment.

Malacia of the spinal cord may manifest as distal progressive muscle atrophy, or be limited to the hands without affecting the forearms and upper arms. Muscle atrophy stops when it reaches a certain extent. Symptoms of muscle atrophy may also be accompanied by sensory impairment, which is more common in the elderly and is often caused by syphilitic vascular lesions.

The initial onset of muscular atrophy is slowly progressive facial muscle atrophy accompanied by inability to close the eyes tightly, puff the cheeks or whistle, atrophy of the humeral muscles, wing-like protrusion of the scapula when the upper limb is raised, and no sensory abnormalities. It manifests as localized atrophy of the temporalis and chewing muscles on one side, and the lower jaw deviates to the affected side when the mouth is opened. It may be accompanied by decreased or absent facial sensation and corneal reflex.

Bilateral shoulder girdle muscle atrophy, accompanied by sensory separation of both upper limbs and chest wall. There is atrophy of the deltoid muscles on one side, inability or weakness of shoulder abduction, no atrophy of other muscles and tenderness in the axilla. There is atrophy of the shoulder girdle muscles on both sides, with an acute history, no paresthesia and local tenderness.

Tongue muscle atrophy is associated with dysphagia and dysarthria. Slow onset of bilateral tongue muscle atrophy accompanied by fasciculations, sudden onset of tongue muscle atrophy without fasciculations, manifested as localized patchy atrophy of the forehead or cheeks, darker skin pigmentation, tense subcutaneous tissue when pinched, and no abnormalities in neurological examination.

The muscles of both hands atrophy symmetrically and slowly, usually not exceeding 1 cm in circumference difference of the same parts of the limbs at the mid-forearm level. After excluding the influence of skin and subcutaneous fat, muscle atrophy may be suspected.
