Reports says- Altered brain connections in epilepsy patients

According to study published in scientific journal Radiology suggests that the patients experiencing the most common form of focal epilepsy have widespread, difficult, abnormal connections in their brains. The surprising thing about these amazing connections is that it could even provide clues toward diagnosis and treatment. This recent research has shown that the default mode network (DMN), the set of brain regions are activated during task-free introspection and also deactivated during goal-directed behavior. This new observation says that these brain connections send clues for treatment of that particular patient. A co-researcher Steven M. Stufflebeam, M.D., from the Athinoula A. Martinos Center for Biomedical Imaging at Massachusetts General Hospital in Boston explains, “Using diffusion MRI, we found alterations in the structural connectivity beyond the medial temporal lobe, especially in the default mode network. The increase in local connections could represent a maladaptive mechanism by which overall neural connectivity is maintained despite the loss of connections through important hub areas.”
