A multidisciplinary sleep clinic

CIRCAE is a sleep centre in Woluwe-Saint-Lambert, in the heart of Brussels. Our sleep clinic brings together, in one place, every skill needed to diagnose and treat sleep disorders: a sleep physician and pulmonologist, neuropsychologists specialised in cognitive behavioural therapy for insomnia (CBT-I), and a team dedicated to fitting and following up sleep equipment (CPAP).

Sleep apnoea, chronic insomnia, snoring, daytime sleepiness, restless legs syndrome, parasomnias or non-restorative sleep: each situation is assessed individually, from the first consultation to sleep examinations (respiratory polygraphy, polysomnography, overnight oximetry) and the start of treatment. Our goal: to restore restorative sleep and reduce the cardiovascular risks linked to sleep-related breathing disorders. Discover the CIRCASLEEP sleep assessment →

The sleep team

Sleep specialists by your side

Our sleep centre brings together complementary practitioners, from medical diagnosis to the behavioural treatment of insomnia.

Sleep examinations

Diagnosing with precision

Every pathway begins with a specialist consultation, followed by targeted examinations based on the patient's clinical profile.

First sleep consultation

Consultation · Doctor + Neuropsychologist

A meeting with two sleep experts to assess the type of disorder and the need for an in-depth assessment.

  • Analysis of your symptoms (fatigue, sleepiness, insomnia, snoring, night-time awakenings)
  • Assessment of medical history, treatments and sleep hygiene
  • Identification of behavioural, psychological and medical factors
  • Referral to the most relevant sleep examination
  • Initial personalised care

Overnight oximetry: O2Fellow

Home examination · Non-invasive

A simple examination carried out at home using a discreet finger ring. It assesses overnight desaturations and the cardiovascular risk associated with apnoea.

  • Oxygen saturation (SpO₂)
  • Heart rate and pulse wave
  • Hypoxic burden: a key indicator of cardiovascular risk

Objectives

  • Detect overnight desaturations
  • Estimate cardiovascular risk
  • Refer to a more comprehensive examination if necessary

Overnight polygraphy

Home examination · Respiratory

Recording of respiratory and cardiac parameters during sleep. Primarily intended for the screening of obstructive sleep apnoea.

  • Respiratory airflow (nasal and oral)
  • Thoracic and abdominal effort
  • Oxygen saturation, heart rate
  • Snoring and body position

Objectives

  • Screen for mild to severe apnoea
  • Quantify apnoeas and hypopnoeas
  • Monitor the effectiveness of CPAP or oral appliance treatment

Full polysomnography

Gold-standard examination · Comprehensive

The most comprehensive sleep examination. It accurately diagnoses respiratory disorders, severe insomnia, parasomnias and restless legs syndrome.

  • EEG brain activity: sleep stages
  • Eye movements (EOG) and muscle activity (EMG)
  • Breathing, saturation, heart rhythm (ECG)
  • Snoring and body position

Results

  • A report including total duration, sleep stages, apnoea/hypopnoea index (AHI), saturation and hypoxic burden
The treatments

Validated and personalised solutions

Our sleep centre combines the gold-standard non-pharmacological and medical treatments, prescribed and monitored by our team.

CBT-I therapy

Gold-standard treatment · Chronic insomnia

Cognitive behavioural therapy for insomnia. A structured programme of 6 to 8 individual or group sessions (45–60 min) aimed at restoring natural sleep without dependence on sleeping pills.

CPAP

Gold-standard treatment · Moderate to severe apnoea

Delivers pressurised air during sleep to keep the airways open. Eliminates apnoeas and reduces snoring and cardiovascular risk.

Mandibular advancement device (MAD)

Oral appliance · Snoring & mild to moderate apnoea

The Oniris+ device holds the lower jaw forward to prevent airway obstruction. Thermo-mouldable, adjustable and comfortable.

Light therapy · AYO

Non-pharmacological approach · Circadian rhythm

AYO glasses emit controlled blue light (20 min/day in the morning). The AYO+ models combine stimulating blue light and relaxing red light to regulate the body clock.

Frequently asked questions

The sleep work-up in practice.

How does a visit to the sleep centre work ?
It starts with a consultation with a sleep physician and a neuropsychologist, who assess your disorder and direct you to the most appropriate sleep test (overnight oximetry, polygraphy or polysomnography), then to a personalised treatment.
What is the difference between polygraphy and polysomnography ?
Overnight polygraphy mainly records respiratory and cardiac parameters, primarily to screen for sleep apnoea. Polysomnography is the most complete test: it adds brain activity (EEG), eye and muscle movements, and can also diagnose severe insomnia, parasomnias and restless legs syndrome.
Do you carry out sleep studies in Brussels ?
Yes. The CIRCAE sleep centre, in Woluwe-Saint-Lambert (Brussels), offers sleep studies (overnight oximetry, polygraphy and polysomnography) as well as CPAP follow-up, with a multidisciplinary team.
