Epilepsy: How we can help
In patients with epilepsy, the cortical functions are often reorganised because of structural malformations that cause epilepsy. Conventional structural imaging of the brain may not easily show the lesion or the effects of seizures.
There is a considerable role for advanced techniques in the detection and characterisation of lesions (using perfusion MRI), as well as the pre-surgical mapping of eloquent cortex responsible for motor, language, memory and sensory functions (using functional MRI), and the mapping of white matter tracts as they traverse either close to or through the lesion (using diffusion MRI) to be able to predict outcomes precisely and as individualised to patients- as no two brains are ever exactly the same. There is also a role of tractography in detecting any residual connections between the normal and abnormal brain once surgery has been performed.
