Seizure Frequency Scoring System

Purpose: To describe the frequency of a patient's seizures using the Seizure Frequency Scoring System of Wang et al.

Description

Wang et al used a Seizure Frequency Scoring System to grade the frequency of seizures in patients following trauma. This can help to determine the severity of seizure disorder and the response to therapy. The authors are from Chang Gung University and National Sun Yat-Sen University in Taiwan, Republic of China.


NOTE: The scale is a modification of the frequency scale of Engel et al (above).
