Background

Identifying where a seizure originates can lead to lifechanging surgery when antiepileptic drugs have failed. Advances in MRI brain scanning have revolutionised the field, however current brain scans are still not sensitive enough to pick up abnormalities in some patients.

Dr Hamandi and his team at Cardiff University and colleagues at Southmead Hospital, Bristol have been awarded a grant to investigate two advanced brain scanning methods; magnetoencephalography (MEG) and functional MRI (fMRI) to better identify areas that cause seizures.

"We have a world leading brain imaging research facility at Cardiff University Brain Research Imaging Centre (CUBRIC) and I am excited by the opportunity of combining the facilities and expertise in CUBRIC with that of the epilepsy surgery programmes in Cardiff and Bristol, building on work that has developed over a number of years, to benefit patients with severe and difficult to treat epilepsy.

The Study

The researchers will use scans and new analysis methods to record brain activity in 30 patients due to undergo a special type of electroencephalogram (SEEG) where electrodes are surgically placed into the brain, pinpointing where seizures arise. The team will compare results from the fMRI and MEG scans – which are considered non-invasive – with the results from the invasive SEEG.

Significance

This study will develop new and safer non-invasive methods to locate epileptic brain areas, in order to offer epilepsy surgery to more patients and with better predicted outcomes. In the future, combining resting fMRI and MEG may become components in the work-up for epilepsy surgery.
