1.What are the neuromuscular diseases included? There are many types of neuromuscular diseases, including peripheral neuropathy; muscle junction diseases, such as myasthenia gravis; skeletal muscle diseases such as polymyositis, periodic paralysis, myotonic dystrophy, metabolic myopathy, congenital myopathy, etc. 2.What are the causes of neuromuscular diseases? Neuromuscular diseases can be divided into two main categories, hereditary and acquired neuromuscular diseases. Hereditary such as hereditary peripheral neuropathy, myotonic dystrophy, congenital myopathy, etc. Acquired include inflammatory, vascular, traumatic, tumorigenic, metabolic and nutritional disorders, infections, poisoning by drugs and chemicals, endocrine disorders, and other etiologies. Systemic systemic medical diseases can also accompany the appearance of neuromuscular disease damage. 3.What does myopathy include? Myopathy mainly includes myotonic dystrophy, myositis, myopathy, etc. 4.How are peripheral neuropathies classified? There are many criteria for classifying peripheral nerve diseases. Generally, they can be divided into hereditary and acquired. Acquired peripheral neuropathies can be divided into nutritional deficiency and metabolic, toxic, infectious, immune-related inflammation, ischemic, mechanical trauma, etc. according to the etiology; according to the course of the disease, they can be divided into acute, subacute, chronic, recurrent and progressive neuropathies, etc.; according to the distribution of the involved nerves, they can be divided into mononeuropathies, multiple mononeuropathies, multiple neuropathies, etc.; according to the The symptoms are divided into sensory, motor, mixed, autonomic, etc.; according to the anatomical part of the lesion can be divided into neuropathy, plexopathy and nerve stem disease. 5.What are the common symptoms of peripheral neuropathy? Common symptoms and signs of peripheral nerve disease include: sensory disorders mainly manifest as sensory loss, sensory abnormalities, numbness, pain, sensory ataxia; motor disorders include motor nerve irritation and paralysis symptoms. Stimulation symptoms are mainly manifested as muscle bundle tremor, muscle fiber tremors, painful spasms, etc., while muscle strength reduction or loss and muscle atrophy are motor nerve paralysis symptoms. Patients with peripheral nerve disease are often accompanied by reduced or absent tendon reflexes. Autonomic nerve damage is often manifested as an absence of sweating, vertical hair disorder and upright hypotension, and in severe cases, tearlessness, salivationlessness, impotence and vesicorectal dysfunction may occur. 6.Common symptoms of muscle disease? Common symptoms of muscle disease include: muscle force weakness, muscle disease often appears in the proximal muscle weakness, different from peripheral neuropathy muscle force weakness often appears in the distal, muscle atrophy or weakness, standing posture or gait; muscle easy fatigue phenomenon, muscle force weakness after repeated exercise, light symptoms after rest, seen in neuromuscular junction lesions, metabolic muscle disease, muscle metabolic disorders caused by pathological muscle fatigue; muscle Pain, myalgia is a characteristic of inflammatory myopathy and metabolic myopathy, and the degree, appearance and precipitating factors of myalgia are different due to different diseases; muscle atrophy, which is an objective indication of muscle lesions. Care should be taken to avoid muscle atrophy being masked by excessive fat and failing to be detected; muscle hypertrophy can be caused by excessive muscle movement, exercise and fatty connective tissue hyperplasia; involuntary muscle movements, such as muscle fibrillation, muscle fasciculation (meat jump), muscle fiber tremors facial twitches and lateral muscle twitches, muscle tonicity, painful muscle spasms and painful muscle contractures, muscle rigidity, muscle contractures, hand and foot twitches; hypotonia; other manifestations Such as skin, bone and joint, eye, endocrine and other abnormalities.
