Machine Learning in Neuroimaging of Epilepsy

Abstract Epilepsy is a prevalent chronic condition affecting about 50 million people worldwide. A third of patients suffer from seizures unresponsive to medication. Uncontrolled seizures damage the brain, are associated with cognitive decline, and have negative impact on well-being. For these patients, the surgical resection of the brain region that gives rise to seizures is the most effective treatment. In this context, due to its unmatched spatial resolution and whole-brain coverage, magnetic resonance imaging (MRI) plays a central role in detecting lesions. The last decade has witnessed an increasing use of machine learning applied to multimodal MRI, which has allowed the design of tools for computer-aided diagnosis and prognosis. In this chapter, we focus on automated algorithms for the detection of epileptogenic lesions and imaging-derived prognostic markers, including response to anti-seizure medication, postsurgical seizure outcome, and cognitive reserves. We also highlight advantages and limitations of these approaches and discuss future directions toward person-centered care.
