We offer diagnostic testing for a wide range of sleep disorders in these specialist groups, including:
The William Quarrier Scottish Epilepsy Centre has a dedicated room specifically equipped for sleep assessments, with extra sound proofing and blackout blinds. These assessments can include full Polysomnography, Mean Sleep Latency Testing (MSLT) and Maintenance of Wakefulness Testing (MWT). We can also provide these patients with full 23 channel EEG and Video Telemetry testing for seizure detection and will soon have the capability to carry out full PSG with an extended 23 channel EEG montage. All sleep assessments are carried out in accordance with the AASM guidelines.
Along with our specialist medical and support team at the Centre, we have an experienced sleep physiologist who is certified by the Board of Registered Polysomnographic Technologist (BRTP).
The William Quarrier Scottish Epilepsy Centre is registered and inspected as an Independent Hospital with Healthcare Improvement Scotland.
Referrals can be made to Quarriers Sleep Services for a number of reasons, including:
Referrals can be accepted from NHS Consultants. We also accept referrals from other medical practitioners where there is a difficulty accessing appropriate services locally.
If you would like to refer a patient to Quarriers Sleep Services, please refer in writing to the Consultant Neurologist or Consultant Neuropsychiatrist. Funding for assessment at The William Quarrier Scottish Epilepsy Centre is organised extra contractually, which must be authorised by the patient’s local Health Board. For more details, contact our Senior Administrator on 0141 445 7750.
Patient is admitted to Quarriers Sleep Service for three nights’ polysomnography.
On the first night, patient has an electrographic seizure discovered by physiologist. This event is not obvious to night staff as the movements are subtle and appear like an arousal from sleep. On closer inspection, patient appears to pick at electrodes and remove some during the post-ictal phase. Spikes are also seen in the inter-ictal EEG.
Her sleep architecture is relatively normal however she has an AHI (Apnoea, Hypopnoea Index) of 17.2 in keeping with moderate sleep disordered breathing (though not obstructive sleep apnoea syndrome as patient does not report day time sleepiness).
In view of these findings, the patient was switched to video EEG monitoring for a more in-depth look at inter-ictal EEG and with a view to capture more seizures with an extended EEG montage. No further seizures are captured although inter-ictal EEG is confirmed as being abnormal with persistent slowing evident and right temporal spikes prominent in sleep. Using evidence from PSG and EEG it is felt that the data supports a focal epilepsy of right hemisphere origin. Before the patient was discharged, the Nurse Specialist advised them to increase their evening dose of Tegretol to 400mg.
Patient’s nocturnal behaviours are more likely to be associated with post-ictal automatism as her epilepsy is not under control as she had thought. No need for second admission to have epilepsy study as sleep/EEG assessments done side by side. Treatment for underlying epilepsy was also able to be implemented on-site during admission.
