Which symptoms are associated with myasthenia gravis?

• A. Ptosis
• B. Difficulty speaking
• C. Difficulty swallowing
• D. All of the above

Answer: (D)

Myasthenia gravis causes fluctuating weakness of voluntary muscles due to impaired transmission at the neuromuscular junction, which tends to worsen with activity and improve with rest. This often involves muscles controlling eye and facial movements as well as bulbar muscles used for speaking and swallowing. Ptosis, or drooping of the eyelids, is a classic early sign. Weakness of bulbar muscles leads to difficulty speaking (dysarthria) and difficulty swallowing (dysphagia). Because these symptoms commonly occur together in MG, all of the above are characteristic features.
