Rhythmic rocking stereotypies in frontal lobe seizures: A quantified video study

Abstract : Objectives.-Rhythmic, stereotyped movements occur in some epileptic seizures. We aimed to document time-evolving frequencies of antero-posterior rocking occurring during prefrontal seizures, using a quantitative video analysis. Methods.-Six seizures from 3 patients with prefrontal epilepsy yet different sublobar local-izations were analyzed using a deep learning-based head-tracking method. Results.-Mean rocking frequency varied between patients and seizures (0.37-1.0 Hz). Coefficient of variation of frequency was low (≤ 12%). Discussion.-Regularity of body rocking movements suggests a mechanism involving intrinsic oscillatory generators. Since localization of seizure onset varied within prefrontal cortex across patients, altered dynamics converging on a ''final common pathway'' of seizure propagation involving cortico-subcortical circuits is hypothesized.
