Registered Charity no. Structural neuroimaging techniques such as CT and MRI can identify underlying structural abnormalities associated with epileptic focus. The underlying mechanisms of such disturbances, and their trajectories over time, are poorly understood and this hampers the development of treatments. Imaging techniques can provide valid and measurable traits ('biomarkers') of disease processes, shedding light on the mechanisms of epilepsy and its comorbidities. In this project, we employ a range of MRI techniques - fMRI, connectivity, diffusion and structural imaging – to investigate the basis of the cognitive and psychological difficulties experienced by many people with epilepsy.
