what is myasthenias gravis?
Answers
Myasthenia gravis (MG) is a neuromuscular disorder that causes weakness in the skeletal muscles, which are the muscles your body uses for movement. It occurs when communication between nerve cells and muscles becomes impaired. This impairment prevents crucial muscle contractions from occurring, resulting in muscle weakness. According to the Myasthenia Gravis Foundation of America, MG is the most common primary disorder of neuromuscular transmission. It’s a relatively rare condition that affects between 14 and 20 out of every 100,000 people in the United States.
SYMPTOMS
What Are the Symptoms of Myasthenia Gravis?The main symptom of MG is weakness in the voluntary skeletal muscles, which are muscles under your control. The failure of muscles to contract normally occurs because they can’t respond to nerve impulses. Without proper transmission of the impulse, a blocked communication occurs between nerve and muscle and weakness results.
Weakness associated with MG typically gets worse with more activity and improves with rest.
