The cause of tardive dyskinesia is unknown. As the disease progresses, the patient may experience symptoms of meat throbbing (myofascial fibrillation) throughout the body. The onset of the disease is insidious and the progression of the disease is slow. The main symptoms include muscle weakness, muscle atrophy and muscle fasciculations. In most cases, atrophy, fasciculations and weakness of tongue extension occur first. As the disease progresses, the affected area gradually expands, and the patient’s hand, arm and scapular band muscles may also develop myofascial fibrillation. As the disease continues to develop, the muscle fasciculations may extend to the neck, trunk, and even the pharyngeal and respiratory muscles, endangering the patient’s life. The prognosis of this disease is poor and there is no effective way to treat it. Once diagnosed, the patient should actively cooperate with the doctor for treatment to alleviate the symptoms and prolong the survival cycle of the patient.
