The patient history and physical examination should direct the type and timing of laboratory and imaging studies. No single sign, symptom, or test dearly differentiates a seizure from a nonseizure event (e.g., syncope, pseudoseizure). Electroencephalography is recommended for patients presenting with a first seizure, and neuroimaging is recommended for adults. Neuroimaging also should be performed in children with risk factors such as head trauma, focal neurologic deficits, or a history of malignancy. Magnetic resonance imaging is preferred over computed tomography except when acute intracranial bleeding is suspected. The most common laboratory findings associated with a seizure are abnormal sodium and glucose levels. Patients with a normal neurologic examination, normal test results, and no structural brain disease do not require hospitalization or antiepileptic medications. Treatment with antiepileptic medications reduces the one- to two-year risk of recurrent seizures but does not reduce the long-term risk of recurrence and does not affect remission rates. Regardless of etiology, a seizure diagnosis severely limits a patient's driving privileges, although laws vary by state.","tracks":[{"project":"PubmedHPO","denotations":[{"id":"T1","span":{"begin":31,"end":38},"obj":"HP_0001250"},{"id":"T2","span":{"begin":157,"end":165},"obj":"HP_0001250"},{"id":"T3","span":{"begin":314,"end":320},"obj":"HP_0000365"},{"id":"T4","span":{"begin":338,"end":345},"obj":"HP_0001250"},{"id":"T5","span":{"begin":377,"end":384},"obj":"HP_0001279"},{"id":"T6","span":{"begin":477,"end":484},"obj":"HP_0001250"},{"id":"T7","span":{"begin":809,"end":828},"obj":"HP_0001939"},{"id":"T8","span":{"begin":847,"end":854},"obj":"HP_0001250"},{"id":"T9","span":{"begin":1144,"end":1152},"obj":"HP_0001250"},{"id":"T10","span":{"begin":1269,"end":1276},"obj":"HP_0001250"}],"attributes":[{"subj":"T1","pred":"source","obj":"PubmedHPO"},{"subj":"T2","pred":"source","obj":"PubmedHPO"},{"subj":"T3","pred":"source","obj":"PubmedHPO"},{"subj":"T4","pred":"source","obj":"PubmedHPO"},{"subj":"T5","pred":"source","obj":"PubmedHPO"},{"subj":"T6","pred":"source","obj":"PubmedHPO"},{"subj":"T7","pred":"source","obj":"PubmedHPO"},{"subj":"T8","pred":"source","obj":"PubmedHPO"},{"subj":"T9","pred":"source","obj":"PubmedHPO"},{"subj":"T10","pred":"source","obj":"PubmedHPO"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"PubmedHPO","color":"#ec93a1","default":true}]}]}}
