In the long-term practice of neuromuscular diseases, we often encounter two types of patients’ families. The first category: panic and not knowing what to do. They blindly listen to the false propaganda of the Internet and travel all over the country to look for famous doctors, hoping that a miracle will appear one day. The second category: listen to fate, let nature take its course and do not treat. These two types of treatment attitude of patients’ families are harmful to the physical and mental health of the affected children. What should parents of children with myotonic dystrophy pay attention to? 1, once the child is diagnosed with progressive myotonic dystrophy, the child should be confirmed as soon as possible to belong to that type of myotonic dystrophy. Because there are many kinds of myotonic dystrophy. The genes that cause the disease are different, and the genetic inheritance of the child is also different. Of course, the treatment and prognosis are not exactly the same. It is important to give up the idea of “no treatment if there is no cure” as soon as possible. At present, there are very few neuromuscular diseases that are truly curable. Most of the so-called “diseases” that can be cured can actually be cured without treatment. About 80% of neuromuscular diseases are related to genetic mutations. Therefore, they cannot be cured. However, treatment can slow down the disease process and improve the quality of life of the affected children. 2. There are many types of hereditary neuromuscular diseases. Genetic diseases do not necessarily have a clear family history in every patient. In particular, it is difficult to find a family history for autosomal recessive disorders. Therefore, regardless of whether there is a family history, it is important to test the genes of onset and the mode of inheritance of the disease to facilitate prenatal diagnosis and avoid recurrence of similar tragedies among family members or relatives. 3. Pseudohypertrophic macromyotrophy (DMD/BMD) is an X-linked recessive disorder. Most mothers of children with DMD/BMD are carriers of the disease. Approximately 30% of mothers of children with the disease may have muscle pain after exercise or heart involvement with palpitations, although they do not have obvious symptoms of muscle weakness or myasthenia gravis. It is recommended to check cardiac enzyme profile and cardiac function, especially for mothers of children with myasthenia gravis or post-exercise palpitations symptoms (electrocardiogram and cardiac ultrasound). The presence of heart sounds and changes in heart rate and rhythm by cardiac auscultation is a simple screening method.
