Adam Bayes

Dr Adam Bayes

MBBS (Hons), BSc, MPsychiatry, PhD, FRANZCP

Consultant Psychiatrist 

Adam is a consultant psychiatrist who specializes in the psychiatric assessment and management of patients aged 17 and over. His approach is initially to undertake a comprehensive assessment usually across two sessions. Then working collaboratively with the patient, a tailored management plan is developed which may include medications, psychological interventions and/or referral for neurostimulation therapies.

Dr Bayes completed his graduate medical studies (Bachelor of Medicine, Bachelor of Surgery) with honours at the University of Sydney, following a degree in Advanced Science. His subsequent postgraduate clinical training in psychiatry was at Prince of Wales Hospital and the Black Dog Institute (BDI) after which he became a Fellow of the Royal Australian and New Zealand College of Psychiatrists. Adam has completed postgraduate degrees including a Master of Psychiatry and also undertook a doctorate (PhD) at the University of New South Wales (UNSW) under the supervision of Professor Gordon Parker.

Dr Bayes’ primary clinical and research interests are in mood disorders (depression and bipolar disorder) including their classification and treatment, in particular novel physical therapies such as neurostimulation. His PhD thesis focused on differentiating the bipolar disorders from personality disorders with the conclusion that rather than being difficult to distinguish, in the majority of cases they can be separated using a small number of key clinical variables. Dr Bayes splits his time equally between clinical and research roles. He currently sees patients in his private rooms at Red Tree Practice and for assessment at the BDI. Additionally, he is a Clinical Senior Lecturer at the UNSW School of Psychiatry within the Faculty of Medicine and a Senior Research Fellow at BDI where he is engaged in research and teaching activities.
