Identify the finding shown in the EEG below:

A 35-year-old female with a history of heroin abuse was found unresponsive and received 35 minutes of CPR before a return of spontaneous circulation (ROSC). She was intubated in the field and was brought urgently to the hospital. While in the ICU, the nursing staff noticed abnormal movements concerning for possible seizure. An EEG was performed and shown below. What is this finding most consistent with?

Stevens-Johnson syndrome associated with carbamazepine use is more likely in patients with which of the following HLA alleles?

An 18-year-old male presents to the ED after having his first generalized tonic-clonic seizure. MRI was unremarkable but a routine EEG showed 4-6 Hz polyspike and wave discharges in sleep. Which of the following antiepileptic drugs are most appropriate to start based on the available information?

An 8-year-old boy with no significant past medical history is brought to the clinic due to difficulties in school. His mother states that over the past year, she has received multiple phone calls from his teacher about his lack of concentration in class. On multiple occasions when asked a question, the patient would blankly stare at the wall and ignore the teacher, but then would return to his normal, talkative self immediately after each episode. An EEG is ordered, which shows 3 Hz generalized spike and wave discharges. The patient would most likely benefit from a medication targeting what?

What clinical diagnosis does this EEG tracing suggest?

A 6-month-old boy with no significant past medical history is brought to the clinic by his father because of abnormal limb movements that occur multiple times a day. His father describes high-frequency, low amplitude rhythmic movements that start in the child’s head and quickly spread down the shoulders. Episodes last approximately 1-2 seconds. There are no clear triggers and there is no loss of consciousness associated with the events. Family history is significant for essential tremor in the patient’s mother. Which of the following is the most likely diagnosis?

A 40-year-old male with bilateral mesial sclerosis and medically refractory epilepsy presents to the epilepsy monitoring unit for a presurgical evaluation. His current anti-seizure medication regimen includes levetiracetam, lamotrigine, and clobazam. Over three days and weaned medication, the patient had 7 seizures; four from the left temporal lobe, and three from the right temporal lobe. Which of the following is the most appropriate next step in treatment?

An 18-year-old woman with a history of symptomatic epilepsy presents with medically-refractory seizures. An MRI brain is performed during presurgical evaluation and reveals the non-contrast-enhancing lesion shown below on T2 FLAIR. This lesion is most likely which of the following?

Based on the EEG shown below, how old is this patient?
