This new edition of Pharmacoresistance in Epilepsy addresses all issues relating to drug-resistance in epilepsy, including studies in patients as well in experimental models and presents the basis for an understanding of recent developments in the pathogenesis and treatment of this condition. Important issues associated with drug-resistant epilepsy are reviewed and updated, such as abnormalities in inhibitory mechanisms, neurotoxicity and changes the immune system associated with this disorder, and the development of drug-resistance as consequence of chronic exposure to antiseizure-medications. Considering that a major obstacle is that epilepsy associated with drug-resistance cannot be controlled with the traditional antiseizure medications, specific chapters describe therapeutic strategies to prevent or reduce the progression of the disease with complementary medical therapies, such as transcranial focal stimulation to promote neuroprotection. Pharmacoresistance in Epilepsy is a valuable resource for anyone working in the field, whether studying epilepsy in the lab or treating it in an office.
