Myasthenia gravis (MG) is a neuromuscular junction disease caused by an autoimmune response against cholinergic receptors. The challenge in diagnosing MG in older patients is the variety of symptoms and clinical manifestations. Clinical reasoning, precise history, and physical examination leading to a logical diagnosis should be performed to diagnose seronegative MG.


Conclusion/Relevance: We report a case of seronegative MG with the chief complaint of dizziness in a 91-year-old female. Despite the complicated clinical course, continuous clinical reasoning and testing can lead to appropriate diagnosis and treatment. As the dizziness symptoms in this older patient could not be explained by chronic or peripheral symptoms alone, ocular MG was considered as a possible diagnosis based on her history and physical examination findings. Appropriate diagnosis of seronegative ocular MG reactivated older patients with a good quality of life. In community medicine, where the behavior of elderly patients varies, it is important to improve the accuracy of diagnosis and treatment through appropriate history and physical examination, which will lead to longer home life in older patients.
