Myasthenia Gravis with Elderly Onset at Advanced Age.

Myasthenia gravis (MG) in older adults has not been extensively studied. The prevalence of this disease in older people seems to be higher in recent epidemiological studies. In patients with disease onset after the age of 70, the diagnosis is more difficult as other conditions are more easily taken to be the causal element. The mortality is higher than in young patients, so prompt specific treatment can improve prognosis. We present an 85-year-old female patient with speech disturbance and difficulty in swallowing solids, and neurological examination with palpebral ptosis, disphonia, convergent strabismus and weakness and mild progressive fatigue in arms, with electroneuromyography and acetylcholine receptor antibody who was diagnosed with MG, emphasizing the importance of this entity in geriatric patients.
