General Neurosurgery: Management of spinal conditions, including disc prolapse, nerve compression, sciatica, and arm pain.

Neurosurgical operative experience
Training

4000 (+) cases (brain, spine, peripheral nerve) as Surgeon or Assistant Surgeon, over ten years in eight neurosurgical units.

Neurosurgical operative experience
Consultant (29 years)

Average of 200 - 300 cases (brain, spine, peripheral nerve) per year

Average of 35 new DBS systems placed annually for Movement Disorders >600patients treated over 20 years - see www.sydneydbs.com for details of this program

Leadership and Advocacy

Dr Cook is a passionate advocate for brain cancer research and improved patient care:

Co-founder and Chairman of The Brain Cancer Group (TBCG), a charity dedicated to brain tumour research, education, and enhanced nursing care.
Frequent presenter at the Neurosurgical Association of Australasia, sharing his extensive experience in glioma resection.

Research and Publications

Dr Cook is widely published in neuro-oncology and functional neurosurgery, contributing significantly to advancements in these fields.

Details of these can be found further down this page.

Teaching and Collaboration

Dr. Cook co-founded Sydney DBS in 2002 alongside Dr. Paul Silberstein as part of the Sydney Deep Brain Stimulation program. For more information, visit sydneydbs.com.

Practice Locations

Dr Cook is based full-time in St Leonards, NSW, and provides care to patients on the Central Coast, including both public and private services.

Charity

Founder / Chairman of Sydney Neuro-oncology Group, a registered charity in NSW focussed on many aspects on brain tumour care including patient and doctor education, research both clinical and more lab based with translational research most important to the group. The group has a brain tumour bank housed at the Kolling Institute (Sydney University) and funds a scientific team researching brain tumours.

In its 21-year existence it has supported multiple PhD students both in Neurosurgery and medical research along with its post-doctoral research scientists. This group often raises>$1M for research annually and has been renamed The Brain Cancer Group.

In 2021 this charity was inducted into “The Founders Circle” at the University of Sydney recognizing contributions made to research conducted at the institution over many years of philanthropy.
