This episode discusses how to semiologically distinguish nocturnal hypermotor (hyperkinetic) seizures typical of sleep-related hypermotor epilepsy (SHE, formerly nocturnal frontal lobe epilepsy, NFLE) from the two main differential diagnoses for paroxysmal sleep behaviours, namely exaggerated/confusional physiological arousals and various parasomnias (in both NREM and REM sleep, especially night terrors and REM sleep behaviour disorder). The semiological features that we focus on are the frequency, timing and duration of the events, whether the events are triggered and whether they have a discrete offset and result in complete arousal from sleep, whether there is subsequent coherent recall, whether the motor features are stereotyped, and a number of other helpful discriminating phenomenological observable motor characteristics. The episode concludes with a discussion on the benefits and challenges regarding inpatient electroencephalography (EEG) monitoring to further assist in diagnosing difficult cases.
