Dr. Jacques Duff

Psychologist and Clinical Neuroscientist


Dr. Jacques Duff is the founder and Clinical Director of the Clinic. From 1997 to 2010 he was involved in Clinical Neuroscience research at the Brain Sciences Institute, investigating "The Brain Electrical Activity of Boys with ADHD and its treatment using Neurotherapy".

Career Overview

Dr Jacques started his working career in Telecommunications in England in 1962. He came to Australia in 1967 and worked for what is now Telstra, as a Senior Telecommunications Technical officer. He left Telstra in 1980 to Study Psychology part time at Swinburne  and finished his postgraduate degree in Psychology in 1999. He started his PhD in Clinical Neuroscience in 1997; at the same time he started the Behavioural Neurotherapy Clinic and studied nutrition.He completed his PhD in 2010.

  • Fellow Applied Neuroscience Society of Australasia (President: 2005-2007)

Experience over and above usual psychological practice

In addition to his psychological practice, Dr Duff has analysed thousands of Quantitative EEG (QEEG) assessments to aid in the differential diagnosis of children with ADHD, ASD and Learning Difficulties and for adults with Traumatic Brain Injuries, PTSD, Psychiatric disorders, Depression and Anxiety. The recordings were carried out by trained QEEG technicians.

Hundreds of these assessments were referred by Psychiatrists and over one hundred were referred by Psychologists.

He developed the Clinic’s two-day "Intensive Behaviour Intervention Course" based on Pivotal Response Treatment to train Psychologists, therapists and parents to deliver Intensive Early Behavioural Intervention for children with Autism Spectrum Disorder. He has also developed on-line courses to teach parents and teachers to manage challenging behaviours at home and in the classroom.

He designed Smart-ehealth and employed software developers to write the software. The purpose of this clinic management and research tool is to collect clinical data in a database and mine this data for research into effectiveness studies of interventions.
