Transient infant movements (TIM): frequent infant non-pathological developmental motor phenomena.

Lombroso and Fejerman, in 1977, described non-epileptic movements in normal infants and named them "benign myoclonus of early infancy", which were recently relabelled by Fernandez-Alvarez as "benign polymorphous movement disorder of infancy" (BPMDI). The focus of our study was to describe, categorize and point out the peculiar clinical representations of these heterogeneous phenomena through our video footage, particularly to those less experienced in paediatric neurology. We included all infants with a video-EEG performed at our unit or a home video recording of "Fejerman-Lombroso", "benign myoclonus of early infancy", "shuddering attacks" or "paroxysmal non-epileptic movements".
