B. Recurrent seizures with abnormal neuronal activity
C. Temporary loss of consciousness only
D. Short-term memory loss
Answer: B
Explanation: Epilepsy is defined by recurrent seizures resulting from abnormal electrical discharges in
the brain.
2. Which of the following best describes a focal seizure?
A. A seizure that originates in both hemispheres simultaneously
B. A seizure limited to one area of the brain
C. A seizure that always leads to loss of consciousness
D. A seizure caused solely by metabolic imbalances
Answer: B
Explanation: Focal seizures begin in a specific area of the brain, which distinguishes them from
generalized seizures.
3. Which seizure type is most commonly associated with a sudden loss of awareness followed by
convulsions?
A. Absence seizure
B. Myoclonic seizure
C. Tonic-clonic seizure
D. Atonic seizure
Answer: C
Explanation: Tonic-clonic seizures, also known as grand mal seizures, typically involve a loss of
consciousness followed by stiffening and jerking movements.
4. How does the International League Against Epilepsy (ILAE) primarily classify seizures?
A. By patient age only
B. By seizure duration
C. Based on seizure onset and semiology
D. According to EEG frequency bands
Answer: C
Explanation: The ILAE classification focuses on the onset of seizures (focal or generalized) and the clinical
manifestations (semiology) observed during the event.
5. What is the role of EEG in the diagnosis of epilepsy?
A. It cures the epilepsy
B. It records the electrical activity of the brain to detect abnormal patterns
C. It measures blood flow in the brain
D. It images the brain’s structure
,Answer: B
Explanation: EEG (electroencephalography) records the brain's electrical activity and is essential in
detecting epileptiform discharges that support an epilepsy diagnosis.
6. Which imaging modality is best suited for identifying structural abnormalities in epilepsy?
A. CT scan
B. Ultrasound
C. MRI
D. X-ray
Answer: C
Explanation: MRI is the preferred imaging modality for detecting structural lesions and abnormalities
associated with epilepsy.
7. What is the primary purpose of long-term video EEG monitoring in the evaluation of epilepsy?
A. To provide a cure for epilepsy
B. To record seizure activity and correlate it with clinical behavior
C. To measure blood sugar levels during seizures
D. To assess the psychological state of the patient
Answer: B
Explanation: Long-term video EEG monitoring combines continuous EEG recording with video to capture
both electrical and clinical seizure characteristics, aiding in diagnosis and treatment planning.
8. Which seizure type is characterized by brief lapses in attention and staring spells?
A. Tonic-clonic seizure
B. Absence seizure
C. Atonic seizure
D. Myoclonic seizure
Answer: B
Explanation: Absence seizures typically involve brief episodes of staring and lapses in awareness, most
commonly seen in children.
9. Which term best describes the warning signs that some patients experience before a seizure?
A. Postictal phase
B. Aura
C. Ictal phase
D. Interictal spike
Answer: B
Explanation: An aura is a subjective sensory or experiential phenomenon that some patients experience
as a warning before the onset of a seizure.
10. What is the significance of identifying seizure semiology in clinical practice?
A. It helps determine the patient’s IQ
B. It assists in localizing the seizure focus and planning treatment
,C. It predicts the exact duration of the seizure
D. It is used to measure blood pressure
Answer: B
Explanation: Seizure semiology, the clinical manifestations observed during a seizure, can help localize
the origin of the seizure and guide therapeutic decisions.
11. Which childhood epilepsy syndrome is known for multiple seizure types and cognitive
impairment?
A. Temporal lobe epilepsy
B. Lennox-Gastaut syndrome
C. Juvenile myoclonic epilepsy
D. Benign Rolandic epilepsy
Answer: B
Explanation: Lennox-Gastaut syndrome is a severe childhood epilepsy syndrome characterized by
multiple types of seizures and associated cognitive difficulties.
12. Which epilepsy syndrome is typically associated with a mutation in the SCN1A gene?
A. Absence epilepsy
B. Dravet syndrome
C. Juvenile myoclonic epilepsy
D. Temporal lobe epilepsy
Answer: B
Explanation: Dravet syndrome is commonly linked to mutations in the SCN1A gene, leading to severe,
drug-resistant seizures beginning in infancy.
13. What is the primary distinction between generalized and focal seizures?
A. The presence of aura
B. The extent of brain involvement
C. The age of onset
D. The duration of the seizure
Answer: B
Explanation: Generalized seizures involve both hemispheres from the start, while focal seizures originate
in a specific area of the brain.
14. Which diagnostic test is considered standard for detecting epileptiform discharges?
A. Blood tests
B. EEG
C. MRI
D. Neuropsychological testing
Answer: B
Explanation: EEG is the standard test for detecting epileptiform discharges that indicate abnormal brain
activity in epilepsy.
, 15. What is the role of sleep-deprived EEG in epilepsy evaluation?
A. It sedates the patient
B. It increases the likelihood of capturing epileptiform activity
C. It measures brain metabolism
D. It evaluates heart function
Answer: B
Explanation: Sleep-deprived EEG is used to increase the sensitivity of EEG recordings by inducing sleep,
which can provoke epileptiform discharges.
16. Which neuroimaging technique uses radioactive tracers to assess brain metabolism in epilepsy?
A. CT scan
B. MRI
C. PET scan
D. Ultrasound
Answer: C
Explanation: PET scans use radioactive tracers to visualize areas of altered brain metabolism, helping to
localize epileptogenic zones.
17. How does SPECT imaging assist in epilepsy diagnosis?
A. By recording electrical activity
B. By evaluating blood flow during seizures
C. By mapping brain structure
D. By assessing cognitive function
Answer: B
Explanation: SPECT imaging measures cerebral blood flow, which can change during seizures, thus aiding
in the localization of the seizure focus.
18. What distinguishes intracranial EEG (iEEG) from scalp EEG?
A. iEEG is non-invasive
B. iEEG provides direct brain recordings with higher spatial resolution
C. iEEG is used only in children
D. iEEG measures blood flow
Answer: B
Explanation: Intracranial EEG involves placing electrodes directly on or in the brain, offering higher
spatial resolution compared to scalp EEG, which is non-invasive.
