EEG

What is the state of the patient in the EEG shown below?

A 19-year-old female who was admitted to the epilepsy monitoring unit for medically refractory epilepsy had one of her typical seizures captured during recording (see below). Which of the following symptoms did the patient most likely experience at the time of this recording?

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?

A 6-year-old Amish female presents to the emergency department with a 2-month history of gradual cognitive decline and jerking limb movements. A routine EEG was obtained (see below). Which of the following diseases is consistent with these EEG findings?

Which way are the patient’s eyes moving at the point of the asterisk marked below?

A 5-month-old female is brought to the emergency room by her parents because of an episode concerning for possible seizure. On arrival, the patient appears back to her clinical baseline neurologically. Several hypomelanotic lesions are appreciated while performing a skin check. The mother notes that her older brother has similar skin findings. An EEG is performed and shown below. A typical event was captured that correlated with an electrodecrement of cortical activity on EEG.

Based on the child’s diagnosis, what is the most appropriate therapy?

What is the most likely clinical scenario related to the EEG provided below?

A mother and father bring in their 8-month-old son to your clinic for clinical events described as sudden flexion of the limbs and trunk, seen most often upon awakening or falling asleep. His interictal EEG is demonstrated below. Which of the following is the most likely cause of the patient’s symptoms and EEG findings?

A patient with a history of focal to bilateral tonic-clonic seizures has an EEG performed to see if they have responded to levetiracetam. Based on the EEG below, from which region of the brain does epileptiform activity arise?

A 45-year-old man suffered a cardiac arrest after a heroin overdose. He received 30 minutes of CPR with an eventual return of spontaneous circulation. After being cooled per post-arrest protocol the patient was rewarmed. 48 hours after being warmed the patient remained in a persistent comatose state with minimal brainstem reflexes. To evaluate the degree of hypoxic-ischemic injury an EEG was ordered. Which of the following EEG patterns carries the worst prognosis after a hypoxic-ischemic injury?

Which of the following is a necessary requirement for electrocerebral inactivity (ECI) testing?

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

Which direction are the patient’s eyes moving at the points marked by the green circles?

A focal seizure must involve how much cortex in order to be appreciated with scalp EEG recording?

A 9-year-old boy with no significant past medical history was referred to get an EEG because of declining school performance and concern for staring vs. daydreaming episodes. Hyperventilation was performed and shown below. His EEG was otherwise unremarkable. Based on the available data which is the most appropriate next clinical step?
