Inadequate experimental methods and erroneous epilepsy diagnostic criteria result in confounding acquired focal epilepsy with genetic absence epilepsy

TL;DR

This paper critiques a neuroscience study for its flawed experimental design and diagnostic criteria, which lead to misleading conclusions about epilepsy types in rats.

Contribution

It highlights the importance of proper experimental methods and diagnostic criteria in epilepsy research to avoid confounding different epilepsy syndromes.

Findings

Identifies poor experimental design in the study

Points out inappropriate epilepsy diagnostic criteria used

Concludes that conclusions about epilepsy types are unwarranted

Abstract

Here we provide a thorough discussion of the study conducted by Rodgers et al. (J Neurosci. 2015; 35(24):9194-204. doi: 10.1523/JNEUROSCI.0919-15.2015) to investigate focal seizures and acquired epileptogenesis induced by head injury in the rat. This manuscript serves as supplementary document for our letter to the Editor to appear in the Journal of Neuroscience. We find that the subject article suffers from poor experimental design, very selective consideration of antecedent literature, and application of inappropriate epilepsy diagnostic criteria which, together, lead to unwarranted conclusions.
