Excessive daytime sleepiness is a common symptom that can stem from a wide variety of causes, ranging from poor sleep habits to underlying medical conditions like sleep apnoea or neurological disorders. Finding the right treatment begins with a comprehensive medical evaluation, which often includes a detailed sleep history and diagnostic sleep studies. Once the precise root cause is identified, a targeted treatment plan can be designed to safely restore your daytime energy and alertness.

A circadian rhythm disorder occurs when the internal body clock (circadian rhythm) is out of sync with the actual environment, leading to severe daytime fatigue or insomnia at night.

Treatment focuses on supporting the body clock to adjust, using techniques such behavioural and lifestyle change, timed light exposure, strategic sleep scheduling, and sometimes melatonin.

Certain sleep conditions can cause severe daytime drowsiness or sudden sleep attacks, significantly increasing the risk of accidents on the road. A formal driving assessment evaluates your alertness and ensures your condition is safely managed according to Australian medical standards. The majority of patients can drive safely and legally with optimal treatment of their sleep disorder. We provide guidance and documentation to satisfy medicolegal requirements.

Idiopathic Hypersomnia is a rare sleep disorder characterised by persistent, debilitating daytime sleepiness despite getting normal or even prolonged amounts of sleep at night. Individuals often struggle to wake up and feel prolonged grogginess after waking. Treatment includes managing symptoms using wake-promoting medications and strategic behavioural strategies to help improve daytime functioning.

Insomnia is a common sleep disorder where there is persistent difficulty falling asleep, staying asleep or waking up too early. This can cause fatigue, low energy and poor concentration throughout the day.

Treatment includes sleep psychology techniques such as Cognitive Behavioral Therapy for Insomnia (CBT-I), which targets the thoughts and behaviours disrupting your rest. This may be combined with sleep hygiene optimisation and in some cases, medication to support change.

Narcolepsy is a neurological disorder that disrupts the brain's ability to regulate sleep-wake cycles, leading to severe daytime drowsiness and sudden, irresistible bouts of sleep. Some individuals also experience cataplexy, which is a temporary loss of muscle control triggered by strong emotions like laughter or surprise. While there is no cure, symptoms are can be effectively managed with the combination medications, scheduled short naps and structured lifestyle adjustments.

Obstructive Sleep Apnoea occurs when the soft tissues of the upper airway temporarily relax and block the throat during sleep, causing you to repeatedly stop breathing for short periods. Symptoms may include loud snoring, gasping for air, and excessive daytime tiredness. Concentration and mood can be negatively impacted.

An overnight sleep study is needed to diagnose OSA. Management can include strategic weight loss, positional therapy, oral appliances or CPAP (continuous positive airways pressure) therapy to keep the airway safely open overnight.

Parasomnias are a broad category of sleep disorders that involve unusual physical behaviors, movements or experiences during sleep. Common examples include sleepwalking, sleep talking, and night terrors, which can be distressing and cause daytime fatigue. Treatment involves identifying underlying triggers, establishing safety, improving sleep hygiene and use of medication.

Periodic Limb Movement Disorder causes your legs or arms to twitch, jerk or kick involuntarily every 20 to 40 seconds while you are asleep. These movements disrupt sleep quality and cause micro-wakes overnight, leading to significant tiredness during the day. Treatment may include correcting underlying deficiencies or using medications to calm the movements.

Restless Legs Syndrome is experienced as an irresistible, overwhelming urge to move your legs, usually accompanied by an uncomfortable crawling or tingling sensation. These symptoms are often worst during rest or in the evening, causing difficulty with falling asleep. Management can includes addressing underlying iron and electrolyte deficiencies, supportive lifestyle changes and targeted medications.

Snoring is the harsh sound produced when airflow causes the relaxed tissues in your throat to vibrate as you breathe during sleep. While most snoring is not harmful, frequent or loud snoring can cause social disturbance and can be due to an underlying issue lsuch as obstructive sleep apnoea. Treatment ranges from lifestyle adjustments, positional therapy and snoring devices.

During normal REM sleep, the body is temporarily paralysed so you cannot move; however, RBD causes this protective paralysis to fail. Symptoms include movement from dream enactment, which can place individuals and bed partners at risk of physical injury. Management prioritises creating a safe bedroom environment alongside specific medications to restore muscle relaxation during sleep.
