57 year-old man with confusion Teaching NeuroImages Neurology Resident and Fellow Section © 2015 American Academy of Neurology

Vignette A 52-year-old man was found wandering at night. He was oriented to name only with no other neurological signs. Routine lab work, CSF analysis and brain MRI were unremarkable. EEG trace is shown in the next slide On recovery, the patient denied previous seizures but admitted to a benzodiazepine habit. Datta., et al © 2015 American Academy of Neurology

Absence status epilepticus in a 50 year-old man with confusion De novo absence status epilepticus is a rare form of non-convulsive status epilepticus. It is encountered in older adults without prior epilepsy. Etiologies include benzodiazepine withdrawal, metabolic derangement and alcoholism 1. Treatment with anticonvulsants used in the idiopathic generalized epilepsies is effective 2. In the above patient levetiracetam resolved his symptoms and normalized the EEG.
