الإجابة: C. EEG
Recurrent stereotyped spells with loss of awareness and focal motor features over a year suggest focal epilepsy. EEG is the test that confirms it: it shows epileptiform spike-and-wave discharges and where they start. Video-EEG helps if routine EEG is non-diagnostic. CT/MRI look for an underlying structural cause rather than confirming seizures, and CSF has no role here.

ليش غلط
CT can exclude a major structural cause, but imaging cannot establish a diagnosis of epilepsy.

MRI shows subtle structural changes such as hippocampal sclerosis (a cause), but imaging cannot establish a diagnosis of epilepsy.

C
ليش صح
The seizure and where it starts are diagnosed with EEG, looking for spike-and-wave activity that indicates organised neuronal firing.

ليش غلط
CSF examination is listed with the tests for an infective or inflammatory cause; the question of whether attacks are truly epileptic is answered by ambulatory EEG or videotelemetry.
