For instance, the seizure semiology of absences as a paradigmatic generalized seizure type is now classified as “non-motor seizure.” A detailed phenomenological analysis reveals that motor activity is an integral part of this seizure type. The new terminology and classification of the ILAE (2017), despite its enormous merits, unfortunately also facilitates and fosters reductionist thinking, which may be pragmatic from a utilitarian perspective, but risks hindering scientific developments for the future. The terms “focal” and “generalized” as used to describe seizures represent abstractions and idealizations rather than ontological entities. Data from semiology, structural, and functional studies using quantitative electroencephalography (EEG), video-EEG monitoring, magnetoencephalography, magnetic resonance imaging, and positron emission tomography as well as neuropathology suggest a nosological spectrum from focal to generalized seizure-generating mechanisms. “focal” which may be counterproductive to the development of new ideas and treatments. Generalized absence seizures are discussed here with respect to changing scientific concepts and newer findings, challenging the strict dichotomy of “generalized” vs. ![]()
