Chronic epilepsy can be classified & effectively treated by clinical evaluation only


Chronic epilepsy can be classified & effectively treated  by clinical evaluation only

In a  cross-sectional study, Dr. Shambhu Kumara and associates have found that Classification of chronic epilepsy into focal and generalized can be done reliably in most patients using clinical information alone without the assistance of investigations like EEG and brain imaging.

Dr.Mamta Bhushan Singh, Professor, Dept of Neurology, All India Institute of Medical Sciences co-researcher in the study said in epilepsy primary care, taking a good history is the key! Most patients can be started on appropriate antiepileptic drugs and made seizure free quite easily and economically. In most patients, expensive investigations may not be needed to start treatment.

 Investigations such as EEG and brain imaging are often difficult to obtain in primary care settings of resource-limited regions impacting millions of epilepsy patients. We wanted to test the hypothesis that classification of chronic epilepsy into focal and generalized based on clinical history and examination alone would be comparable to making such a classification with additional inputs from EEG and brain imaging.

Two investigators independently classified consecutive chronic epilepsy patients into focal, generalized and unclassified epilepsy.

Investigator 1 made this determination using clinical history and examination alone whereas Investigator II additionally used EEG and brain imaging too. We calculated interobserver agreement between the two investigators and also looked at the predictors of focal and generalized epilepsy.

Five hundred and twelve patients were recruited. Interobserver agreement between the two investigators in making the focal versus generalized classification was 96.8%, kappa 0.91 (p < 0.0001). When EEG and neuroimaging findings were added to the clinical information, there was a change in classification in 3.2% patients.Several predictors of focal and generalized epilepsy were identified.

The Authors concluded that Classification of chronic epilepsy into focal and generalized can be done reliably in most patients using clinical information alone. Investigating chronic epilepsy patients with EEG and brain imaging may not be necessary for every patient. The results of  study are especially significant for epilepsy patients living in resource-limited regions where such investigations may not always be available
