How to conduct a sleep test?

An overnight polysomnography (PSG) is the recommended diagnostic test for any sleep-related breathing disorders, it involves measuring the child’s brain waves, snoring sound, breathing patterns, eye activities, chest and abdominal movements, oxygen saturation and muscle activities. In certain occasions, we will also video record the child’s sleep. The recordings will help us to find out whether the child has breathing problem at night and its severity, which is important to guide treatment prescription.

Obstructive Sleep Apnoea (OSA)

Sleep is crucial and plays a vital role in our overall well-being. In fact, we spend approximately one-third of our lives asleep. Current scientific evidence suggests that sleep serves numerous important functions, including the removal of waste materials from our brain, the consolidation of memories, and the secretion of essential hormones, etc. Achieving good sleep requires both optimal quantity and quality.

In children, one of the most common causes of poor sleep quality is obstructive sleep apnoea (OSA). Typical symptoms of OSA in children include frequent snoring, restless sleep, mouth breathing, and night sweats. Interestingly, some of the daytime symptoms of OSA overlap with those observed in children with attention deficit hyperactivity disorder (ADHD), such as poor attention, behavioural issues, and temper tantrums.

Therefore, if your child displays symptoms associated with ADHD, it is important to ensure that their sleep is optimal besides considering the diagnosis and management of ADHD. Addressing and improving their sleep quality may have a positive impact on their overall well-being and potentially alleviate some of the ADHD-related symptoms they may be experiencing.


Common symptoms of OSA:

  • Snoring
  • Restless sleep
  • Mouth breathing
  • Night sweats

Some of the daytime symptoms of OSA overlap with those seen in a child with attention deficit hyperactivity disorder (ADHD):

  • Poor attention
  • Behavioural issues
