What Is a Combined Video Polysomnography PSG with Full EEG?
A Combined Video Polysomnography (vPSG) PSG with Full EEG is the most advanced overnight study for investigating complex night-time sleep events.
Our specialist test records detailed brain activity together with physiological and behavioural data, enabling clinicians to determine whether unusual movements, loss of awareness, or disruptive behaviours are caused by a sleep disorder, epilepsy, or both.
Importance of taking a combined vPSG with full EEG
A Combined vPSG with Full EEG is performed by synchronising brain, body, and behavioural data, it provides unmatched clarity in distinguishing between parasomnias, nocturnal seizures, and other complex conditions. This level of precision ensures patients receive an accurate diagnosis and a treatment plan tailored to their needs.
When Should I Take This Test?
A Combined vPSG with Full EEG is recommended when standard sleep studies have not provided answers, or when clinicians suspect that night-time episodes may be neurological in origin. It is especially valuable for patients with suspected epilepsy, disruptive or dangerous behaviours during sleep, unexplained collapses or confusion at night, or for children presenting with complex or mixed symptoms.
What the Test Measures
A Combined vPSG with Full EEG records three main areas of information:
Neurological activity through a full EEG montage to identify and localise abnormal brain signals
Behavioural patterns via continuous high-definition video, capturing movements and episodes in real time.
Physiological functions such as eye movements (EOG), muscle tone (EMG), heart rhythm (ECG), breathing and oxygen levels, airflow, snoring, and body position.
By bringing these data together, clinicians can match abnormal electrical brain activity with physical behaviours and sleep stages, offering a complete picture of what happens during the night.
How the Test Is Performed
The assessment is carried out overnight in one of our specialist centres or in the comfort of your own home. Throughout the study, our Clinical Neurophysiologists and Sleep Physiologists provide continuous monitoring, ensuring patient comfort and safety. The results are then reviewed by a consultant Neurophysiologist and a Consultant Sleep Physician, who provide a detailed, synchronised report covering EEG analysis, video observations, respiratory parameters, and clear diagnostic conclusions.
