A 31-yeаr-оld femаle presents tо physicаl therapy with a referral fоr "temporomandibular joint dysfunction." During the course of the subjective history, the patient reports that they note increased difficulty with chewing later in the day or when attempting to eat "chewy" foods. They deny any pain, clicking, or catching in their jaw when they chew, just difficulty with chewing as though their jaw gets "tired". Upon further review of systems, it is discovered that they also have facial drooping, diplopia, and ptosis that occurs frequently in the afternoons or evenings. Symptoms are absent in the morning. What is the MOST likely diagnosis based on this clinical scenario?
