Mr L. Zrinzo


Mr Ludvic Zrinzo MD PhD FRCSEd

Mr Zrinzo holds the post of Consultant and Senior Lecturer in Neurosurgery at the Unit of Functional Neurosurgery.

Having qualified in Medicine from the University of Malta, Mr Zrinzo moved to London to pursue a career in Neurosurgery. His interest in Functional Neurosurgery commenced when visiting the Neurosurgical Department in Lund, Sweden as a medical student and developed further while pursuing an MSc in Clinical Neuroscience at UCL Institute of Neurology, for which he was awarded a Distinction.

Mr Zrinzo pursued two Stereotactic and Functional Fellowships, at Queen Square, London and at the University of California, Los Angeles (UCLA) under the aegis of Professors Marwan Hariz and Antonio DeSalles, respectively.

He was awarded a PhD by the UCL Institute of Neurology for work on “MRI Guided and MRI Verified Deep Brain Stimulation: Accuracy, Safety and Efficacy”.

This clinically relevant research has improved the accuracy of anatomical targeting during DBS procedures and has helped introduce several new brain targets and indications for DBS to the National Hospital. He also has a busy General Neurosurgical practice. Current interests include DBS in severe refractory forms of Tourette syndrome, obsessive-compulsive disorder, cluster headache and other trigeminal autonomic cephalalgias.
