Refractory epilepsy.

Area of Science:

• Neurology
• Epileptology

Background:

• Refractory epilepsy (R.E.) is defined by the failure of antiepileptic drugs (AEDs) to achieve seizure control.
• Accurate diagnosis requires excluding false refractoriness.
• Predictors of R.E. have been identified.

Purpose of the Study:

• To review the diagnostic considerations for R.E.
• To outline current and future treatment options for R.E.

Main Methods:

• Literature review of refractory epilepsy diagnosis and management.
• Synthesis of information on predictors, current treatments, and emerging therapies.

Main Results:

• Several predictors indicate potential refractoriness.
• Established treatments include resective surgery, ketogenic diet, and vagal nerve stimulation.
• Newer AEDs show promise.

Conclusions:

• Accurate diagnosis is crucial to avoid misclassifying epilepsy as refractory.
• A range of treatment modalities exist for R.E., from established to experimental.
• Future therapies like deep brain stimulation, gene therapy, and stem cells offer new hope.
