About Dr Vicky Chang
Dr Vicky Chang is a Sleep Medicine Specialist in Wagga Wagga, NSW, Australia.
Sleep medicine involves the diagnosis and treatment of a wide range of problems associated with sleep. Over 100 different disorders of sleeping and waking have been identified, grouped in four main categories: problems with falling and staying asleep (insomnia); problems with staying awake (excessive daytime sleepiness); problems with keeping to a regular sleep schedule (sleep rhythm problem); and unusual behaviours during sleep (sleep-disruptive behaviours, e.g. sleep walking). Tests and treatment vary and depend on the specific sleep disorder.
