Answer

Physical examination findings are normal in patients with narcolepsy. A careful neurologic examination should be performed to exclude other causes of the patient’s condition, including an underlying structural abnormality. There are no specific physical findings that suggest narcolepsy, though obesity may be associated with the disorder. During an episode of cataplexy, patients typically demonstrate atonia of muscles of the limbs and neck and loss of deep tendon reflexes.
