The probability of remaining seizure-free after treatment discontinuation is about 70% at 2 years. The individuals need be reevaluated the therapeutic strateagies, and increase the hope to reach real seizure-free.Įpilepsy is a chronic disease need long-term management. The LTM EEG recording may help find epileptiform activity in high risk seizure-free individuals. The study indicated a correlation of a number of factors with abnormal LTM EEG presentation: symptomatic or cryptogenic epilepsy, history of cerebral trauma, history of cerebral surgery, and abnormal imaging findings. The following factors suggested a correlation between history of cerebral trauma (HR = 2.4) and history of cerebral surgery (HR = 3.4) with epileptiform activity on LTM EEG presentation by multivariate logistic regression analysis. We found several clinical factors could be associated with epileptiform activity on LTM EEG in seizure free patients by a one-way analysis: symptomatic or cryptogenic epilepsy, history of cerebral trauma (HR = 7.5), and abnormal imaging findings (HR = 3.1). We found that more epileptiform activity were found with LTM EEG recording than regular EEG recording in seizure-free individuals. We analysed the data by one-way analysis of variance and Cox proportional hazards models. We collect the demographic and clinical information and LTM EEG data of these 262 individuals. Two hundred sixty-two individuals accorded with the inclusion criteria and exclusion criteria. The LTM EEG recordings of 770 individuals with a definite diagnosis of epilepsy were assessed. We hope that the detection of epileptiform activity by the LTM EEG recording can develop the better treatment strategy. We try to look for clinical factors associated with epileptiform activity on LTM EEG in seizure free patients. This study aimed to explore the clinical value of long - term electroencephalogram (LTM EEG) in seizure-free individuals taking antiepileptic drugs (AEDs) for more than 2 years.
