Sleep Disorder Assessment & Therapy

Specialist sleep disorder evaluation and treatment by a dual-qualified psychiatrist-sleep physician, including polysomnography, sleep actigraphy, CBT-I, CPAP therapy, and Chronotherapy.

SH Wong Sleep & Psychological Wellness Clinic offers one of Singapore's most comprehensive sleep medicine programmes, led by Dr. Wong Sheau Hwa — a Senior Consultant Psychiatrist with a specialist interest in sleep disorders and over 26 years of clinical experience. The sleep service begins with a detailed clinical assessment to identify the underlying causes of sleep disruption, which may include insomnia, obstructive sleep apnoea, restless leg syndrome, narcolepsy, or circadian rhythm disorders. Where a sleep study is indicated, the clinic offers home-based polysomnography — a comprehensive overnight assessment that monitors brain waves (EEG), oxygen saturation, heart rate, respiratory effort, and body movement. Sleep actigraphy, using a wrist-worn device over multiple nights, provides a complementary picture of sleep-wake cycles and circadian patterns in the patient's natural environment. Cognitive Behavioural Therapy for Insomnia (CBT-I) is the flagship non-pharmacological treatment offered, structured across multiple sessions and incorporating sleep restriction therapy, stimulus control, sleep hygiene education, relaxation training, and cognitive restructuring. This approach is recommended over long-term sedative use by international sleep medicine guidelines. For patients diagnosed with obstructive sleep apnoea (OSA), the clinic provides CPAP (Continuous Positive Airway Pressure) therapy initiation and titration, with ongoing support for mask fitting and adherence. Chronotherapy is also available for patients with delayed sleep phase disorder or other circadian misalignments, involving structured sleep schedule shifts to resynchronise the body clock. Given the frequent co-occurrence of sleep disorders and psychiatric conditions — particularly depression, anxiety, and PTSD — Dr. Wong's dual expertise allows integrated assessment and treatment that single-specialty clinics cannot provide.
