Girls born with muscle atrophy may be associated with genetic factors, gene mutations, immunity, etc. It is seen in diseases such as myotonic dystrophy, multifocal motor neuropathy, and spinal muscular atrophy.
1. Myotonic dystrophy: this disease is a hereditary muscle degeneration disease, characterized by progressive aggravation of muscle weakness and muscle atrophy. Typical symptoms of the patients are slow walking, toe landing, easy to fall, difficulty in walking up stairs, with abdominal and strong lumbar muscle weakness.
2. Multifocal motor neuropathy: chronic progressive focal lower motor neuron damage, presumably an autoimmune disease associated with anti-ganglioside antibodies. Clinical manifestations include asymmetric limb weakness, atrophy, and muscle twitching, with minimal sensory involvement.
3. Spinal muscular atrophy: it is a group of hereditary diseases, most of which are recessive and associated with the motor neuron survival gene on chromosome 5. Clinically, it is characterized by progressive symmetrical proximal muscular atrophy, with selective involvement of lower motor neurons and no upper motor neuron involvement.
Girls born with muscle atrophy may also be caused by other diseases, it is recommended to consult a doctor in time to clarify the cause of the disease and targeted treatment.
