Diagnostic Code 8025 · 38 CFR §4.124a
Myasthenia gravis (MG) is a chronic autoimmune condition where antibodies attack the connection between nerves and muscles, causing fluctuating muscle weakness that worsens with activity and improves with rest. Common symptoms include drooping eyelids, double vision, difficulty speaking and swallowing, and weakness in the arms, legs, and breathing muscles. The hallmark of MG is fatigable weakness — muscles work at first but quickly tire out. Veterans may develop MG as an autoimmune response triggered by stress, infections, or toxic exposures during service. The minimum VA rating for myasthenia gravis is 30%.
