There is no cure for childhood muscular dystrophy, and supportive treatment is currently the mainstay. Myotonic dystrophy in children is a hereditary disease characterized by progressively worsening skeletal muscle weakness and atrophy, and in severe cases it can involve the heart muscle and lead to heart failure. There is no cure for childhood muscular dystrophy, but only rehabilitation and supportive therapy to slow down the rate of muscle atrophy, and life support for severe cases. It is recommended that children with myotonic dystrophy seek medical attention in a timely manner, and under the guidance of a doctor to carry out professional rehabilitation training, such as wearing a brace, surgical treatment, etc., to slow down the progression of the child’s condition, and to improve the quality of life of the patient.
