Disease profile
A grounded synthesis of the condition — overview, causes, mechanism, risk factors and current standard of care.
Drug resistant epilepsy is an epileptic condition in which adequate trials of two tolerated and appropriately chosen antiepileptic drug schedules fail to achieve sustained seizure freedom. It is a treatment-refractory form of epilepsy and is commonly discussed in the context of diagnosis and therapy.
The grounding does not provide a specific disease mechanism for drug resistant epilepsy itself. It does indicate that some therapies act by modulating neural circuits, including thalamocortical circuits via vagus nerve stimulation and adaptive intracranial EEG-guided stimulation with responsive neurostimulation.
Management is described at the modality level and includes non-pharmacologic adjunctive therapies for patients who remain uncontrolled after appropriate antiseizure medications. These include ketogenic diet therapy and neurostimulation approaches such as vagus nerve stimulation, deep brain stimulation, and responsive neurostimulation. The grounding also notes that these techniques are used as adjuvant therapy in some patient populations.
