Helping you get a good night's sleep

Sleep is vital to our health and wellbeing. Yet up to 1 in 4 people in the UK have a sleep disorder. Unfortunately, this means that many experience excessive tiredness during the day, affecting their concentration, mood and work and family life. Importantly, some sleep disorders which disrupt breathing, such as sleep apnoea, can lead to an increased risk of heart disease and stroke.

Our consultants have an international reputation in advancing sleep medicine, particularly in sleep apnoea and domiciliary ventilation (providing breathing support at home). We offer investigations and treatments across the full spectrum of sleep disorders to help patients get the rest they need.

Advanced sleep studies

We offer a range of sleep studies at our state-of-the-art facilities to help with diagnosis, including:

  • assessment of sleepiness (multiple sleep latency test, Osler wake test)
  • detailed polysomnography studies
  • home sleep studies
  • respiratory sleep studies
  • sleep-wake activity levels (actigraphy)

Expert sleep care

We diagnose and treat all types of sleep conditions, including:

  • circadian rhythm disorders (disruption of the body clock, such as from jet lag or shift work)
  • idiopathic hypersomnia (long-term daytime sleepiness)
  • insomnia (difficulty getting to and staying asleep)
  • REM sleep behaviour disorder (nightmares and acting out dreams)
  • restless leg syndrome (an overwhelming urge to move your legs)
  • narcolepsy (a long-term brain condition that can prevent you from choosing when to sleep)
  • nocturnal hypoventilation (breathing that is too low or shallow during sleep)
  • parasomnias (sleep walking, talking, nightmares, sexsomnia)
  • sleep apnoea (disrupted breathing during sleep)
  • troublesome snoring

CBTi: Sleep therapy for insomnia

Insomnia is a type of sleep disorder which affects a person’s ability to fall asleep or stay asleep.

Cognitive behavioural therapy for insomnia (CBTi) is recommended by the The National Institute for Health and Care Excellence (NICE) as the gold standard treatment for insomnia.

We are one of the few centres that offer a private CBTi programme. It can address sleep disturbances within 8 weeks, helping reduce sleep-related anxiety and behavioural sleep issues as well as aid relaxation for improved sleep quality.

Specialist non-invasive ventilation at home

Our advanced sleep medicine facilities enable our experts to diagnose and treat sleep disorders in patients with complex conditions affecting their breathing. These include cystic fibrosis, COPD, curvature of the spine and neuromuscular disorders (such as muscular dystrophy and motor neurone disease). These conditions can lead to under-breathing during sleep, leading to high levels of carbon dioxide in the blood (called ‘nocturnal hypoventilation’).

Our consultants pioneered the use of non-invasive ventilation in adults and children with nocturnal hypoventilation and now care for 1,600 patients with small portable ventilators at home. This treatment has revolutionised outcomes for these conditions including extending life expectancy, reducing hospital admissions and improving quality of life for patients.
