Clinical Efficacy and Safety of Perampanel Monotherapy in the Treatment of Children With Focal Epilepsy

Study Overview
=================
Brief Summary
-----------------
This project is a multicenter prospective study. By retrieving outpatient medical records and collecting clinical data of epilepsy patients, the efficacy and safety of single-drug perampanel in patients with focal epilepsy were analyzed.

Detailed Description
-----------------
This project is a multicenter prospective study. The selected case population was given the oral antiepileptic drug perampanel for 12 months, and the seizure control (complete control, markedly effective, effective, ineffective, worsening), EEG changes (normal, Effective, ineffective), and adverse reactions were analyzed, so as to provide a basis for perampanel monotherapy in children with focal epilepsy.

|Drug: perampanel|China's state food and drug administration approved indications for adults and children aged 4 or more focal epileptic hair company or not with secondary comprehensive seizures of epilepsy, adding treatment, in July 2020 to monotherapy without clinical approval, the current domestic perampanel monotherapy clinical effectiveness and safety of focal epilepsy in children have not been reported.|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| clinical efficacy after drug treatment: | Epilepsy seizures: the seizure frequency 3 months before treatment is the baseline, and the maintenance period is compared with the baseline. Complete control: no seizures after treatment; markedly effective: seizure frequency reduced by > 75%; effective: seizure frequency reduced by > 51%-74 %; Ineffective: frequency reduced by ≤50%, worsening: attack frequency increased by 25%. | one year | 
| EEG changes after drug treatment | EEG changes: (1) normal EEG (2) abnormal EEG: including epileptiform discharge, background rhythm slowing, epileptiform discharge + background rhythm slowing. EEG judgment: (1) normal: the epileptiform discharge disappeared or the background slowing disappeared (2) effective: the epileptiform discharge was reduced or the background slowing was improved (3) invalid: the epileptiform discharge did not change or aggravate after the drug. | one year | 
| safety after drug treatment | Common adverse reactions include: dizziness, drowsiness, fatigue, irritability, nausea and falls and weight gain. | one year |
