Changes of electromyogram in myasthenia gravis

summary

Recently, I always feel that I don't have strength. At first I thought I had a cold, but then I went to the hospital for examination. The doctor said that I was suffering from myasthenia gravis. After treatment, the doctor has been much better. I'd like to share the experience of EMG changes of myasthenia gravis with you

Changes of electromyogram in myasthenia gravis

Symptom 1: congenital myasthenia gravis syndrome is rare, often autosomal recessive inheritance. The defect may be presynaptic, synaptic or postsynaptic. Most of the cases originate from postsynaptic membrane and are due to the defect of acetylcholine receptor. The number of patients with onset before 2 years old was more than that of adolescents, and the onset was progressive.

Symptom 2: children with congenital myasthenia gravis syndrome generally have less fetal movement before birth, and onset at birth or shortly after birth. The level of acetylcholine receptor antibody in blood is not high, and plasma exchange therapy is ineffective, so it is different from acquired autoimmune myasthenia gravis.

Symptom 3: born to a non myasthenia gravis mother, the symptoms are mild but persistent at the onset, often accompanied by facial myasthenia, which can affect feeding. General weakness is dispensable, but generally not serious. There was no complete remission.

matters needing attention

I also want to emphasize: in the treatment of myasthenia gravis blepharoptosis, we should pay attention to excessive sadness, anger, cold, acute bronchitis, pregnancy or childbirth, which can aggravate the symptoms of myasthenia gravis. Some antibiotics can aggravate the effect of myasthenia gravis, so we should pay attention to them. In the treatment of myasthenia gravis, we should pay attention not to use drugs indiscriminately. If myasthenia gravis, dysphagia, water choking cough, chest tightness, shortness of breath and other symptoms are caused by infection or improper use of drugs, we should see a doctor in time.
