ABSTRACT
OBJECTIVE: To investigate the clinical characteristics and electromyographic findings of a patient with acetylcholine receptor (AChR) antibody-positive myasthenia gravis (MG) overlapping with Kennedy's disease (KD), aiming to improve clinicians' recognition of this rare overlap syndrome and explore potential comorbid mechanisms.
METHODS: The clinical presentation, laboratory results, and neurophysiological features of one case with AChR antibody-positive MG and KD were analyzed. A literature review of MG overlapping with KD was performed.
CONCLUSION: Neurophysiological findings and androgen receptor gene testing results were consistent with a diagnosis of KD. Therefore, the patient was definitively diagnosed with overlap syndrome of AChR antibody-positive MG and KD. A literature review identified only four previously reported cases of KD patients exhibiting myasthenic features; however, all were AChR antibody-negative.
