This is a review of the use of neuroimaging in epilepsy outlining the imaging strategy for new onset seizures and also those with intractable focal seizures being investigated as potential epilepsy surgery candidates. The review describes the radiological features of conditions which may be encountered in each clinical context, together with advice on the optimum imaging protocols to detect epileptogenic lesions. The review also presents the role of imaging in presurgical planning, the demonstration of eloquent function, grid placement and postoperative assessment.

There is evidence that at least 5% of Multiple sclerosis (MS) cases manifest in childhood. Children with MS present with a demyelinating episode involving single or multiple symptoms prior to developing a second event (usually within two years) to then meet criteria for diagnosis. There is evidence from adult cohorts that the incidence and sex ratios of MS are changing and that children of immigrants have a higher risk for developing MS. A paediatric population should reflect the vanguard of such changes and may reflect trends yet to be observed in adult cohorts. Studying a paediatric population from the first demyelinating event will allow us to test these hypotheses, and may offer further valuable insights into the genetic and environmental interactions in the pathogenesis of MS.
