Mr McEvoy performs all surgical therapies for the management of epilepsy such as temporal lobe resections, hemispherotomy, corpus callosotomy, vagal nerve stimulation and gamma knife surgery. He has a number of ongoing research interests examining the technique of EEG-FMRI, the evaluation of functional deficit following epilepsy surgery resection and imaging of the optic radiation to prevent visual field defects in temporal lobe surgery.


Further detail

Listed in The Times 2010 top UK doctors for his epilepsy and brain tumour surgery,
Mr McEvoy’s specialist neurooncology service has a particular interest in the prediction and preservation of function during large resective neurosurgical procedures and the reorganisation of brain function around brain tumours. This multidisciplinary approach integrates facilities such as 3T MRI, FMRI for language and motor function, DTI, MEG, neurophysiology and neuropsychology.

As a result of this expertise, he performs probably the largest number of ‘awake’ craniotomies presently in the UK. This enables the largest possible resection of brain tumours while minimalising neurological deficit Gamma Knife and Cyberknife ensure that patients have access to the most extensive treatment options available at any centre throughout the world.

His busy general neurosurgical practice encompasses spinal surgery, trigeminal neuralgia, hydrocephalus, head injury and peripheral nerve surgery. Mr McEvoy has published and presented widely both nationally and internationally and hold a number of research grants funding ongoing projects at The Institute of Neurology in London.
