Video EEG Monitoring: Seeing Seizures as They Happen

Why a Routine EEG Is Sometimes Not Enough

A standard EEG lasts under an hour and may not capture a seizure or the abnormality causing it — seizures are intermittent, and a brief recording can miss them. When the diagnosis is unclear, or seizures are not responding to treatment, a longer, more detailed recording is needed. That is where video EEG monitoring comes in.

How Video EEG Works

The patient stays in a specially equipped room where EEG electrodes continuously record brain activity while synchronised video captures their movements and behaviour. This continues for hours to several days until enough events are recorded. Reviewing the seizure on video alongside the exact brain activity at that moment gives neurologists information no other test can provide.

What It Reveals

Video EEG answers questions that change management: Are these episodes truly epileptic seizures, or something else that mimics them? What type of seizures are they? And critically, where in the brain do they start? Localising the seizure onset is the key step in deciding whether epilepsy surgery is possible and where it would target.

Who Benefits

Video EEG is particularly valuable for people whose seizures are not controlled by medication, whose diagnosis is uncertain, or who are being assessed for surgery. Having this capability in-house means Health1 can fully evaluate complex epilepsy rather than managing it partially or referring it elsewhere.
