4. Changes in Voice
Typical symptoms of the condition affect the eyes first, before spreading to the neck. Myasthenia gravis patients experiencing bulbar symptoms may notice changes in their voice as symptoms progress.
Speech and vocal symptoms include vocal fatigue, hoarse voice, difficulty controlling pitch, slurred speech, and monotone or hypernasal voice. Laryngologists describe “isolated myasthenia gravis” as the condition causing these symptoms, without showing any of the signs of muscular fatigue or weakness in the eyelids or eyes.
Tests conducted on individuals experiencing changes in voice may come up as negative for myasthenia gravis, making it challenging for medical professionals to identify the disorder as the cause of vocal changes.
The use of myasthenia gravis treatment drugs can reduce symptoms and return the voice to its normal pitch and tone. However, if you notice these symptoms in conjunction with the weakness of the facial muscles, it’s almost certain that the vocal issues are related.
