Based on the symptoms provided in the article (such as muscle weakness and difficulty speaking and swallowing), the official diagnosis of myasthenia gravis is the most likely option. Lupus and MS can also cause similar symptoms, but myasthenia gravis is characterized by specific symptoms that distinguish it from these other conditions. Lambert-Eaton syndrome is another rare neuromuscular disorder with similar symptoms, but it is less likely than myasthenia gravis. Muscular dystrophy is generally characterized by progressive muscle weakness, not sudden onset like Kathryn D. experienced.
