THE DIAGNOSTIC BRAIN PORTALwas created as'THE SOLUTION' for the many mentally suffering.

     Who, despite seeing or being under the care of many mental health specialists such as (psychiatrists; GPs; psychologists and therapists), and yet have failed to get better!

Our research shows that prior to attending, The Neurodiagnostic Centre, our patients had consulted or been under the care of an average of 4 mental health professionals and yet, have failed to get better! 













 The portal will....

Graduate of the Otago Medical School (N.Z.) John is a Life Member and Fellow of the Royal Australian College of General Practice; Fellow of the Australian Society of Psychological Medicine; Analytical Psychotherapist; Neuroscientist, entrepreneur and Author residing in Perth, Western Australia.

John, although not a Psychiatrist, undertook an alternative educational pathway and currently consults locally, nationally and internationally in the field of Neuropsychiatry, endeavouring to add value, diagnostically to an individual’s mental health evaluation, by undertaking the most scientific approach possible.

John is also the medical director of the Neurodiagnostic Centre, past member of the Advisory Board of Notre Dame Medical School in Fremantle, and a non-executive director of the Global Mind Screen Group. He actively presents to the public and profession on a variety of topics, ranging from conditions such functional brain imaging, mood and anxiety disorders, (particularly Social Anxiety Disorder), Adult ADHD, and brain insult and trauma, together with numerous lifestyle topics.


Understanding  functional Brain imaging in Mental Health Evaluation


Picture1.png   The evolution of advanced imaging cameras and computer technology has seen the advent of such (sex and age corrected) data-bases, so allowing clinicians now to see how patient symptoms, such as obsessions or road rage might occur as an alteration of brain functioning.




Picture1.png  Today, the increased knowledge gained from functional brain imaging has provided clinicians with an added tool of scientific information to compliment their clinical assessment, particularly in the group of the more difficult patient group often labelled, treatment resistant.



Picture1.png Finally, the consequence of such medical progress has allowed clinicians to better understand their patients and their symptoms. In so doing, they are achieving better outcomes than previously, due to such advancements, which has allowed them to tailor-make medication and treatment programs more appropriately suited to the individual’s needs.



What is SPECT?

[Single Photon Emission Computerized Tomography]

SPECT is a functional nuclear medicine study that looks directly at the flow of blood to the different regions of brain [cerebral blood flow] and indirectly at a patient’s brain cell’s metabolism and chemical [neurotransmitter] activity. In other words, how their brain is working.

A harmless radioactive isotope bound to molecules is injected into the patient’s blood stream, whereupon it travels to the brain to be taken up differentially in different sites depending on the activity of the neurone’s receptors at that site.

The patient then lies still for approximately 15 minutes, while the SPECT camera takes its images, which are reconstructed into coloured 3-D images and slices by modern computer technology. With these sophisticated images physicians are able to map and then identify certain patterns of brain activity that correlate with psychiatric and neurological conditions.


functional Brain Imaging:


 The quality of our lives is but a mirroring of the delicate balance between “mind” and “brain.” The “brain” with its neural pathways and neurochemical messengers filters our outer world - so influencing mind; 

The “mind” (our inner world) supplies its rich matrix of feelings, intuition and memory – so influencing “brain”.

functional Brain Imaging provides us with 'a portal to see the brain at work' and in so doing allows us to learn more about the troubled and distressed mind and how it differs from a mind at peace!
