Patient 5 was a 50-year-old female at the time of EEG monitoring. During wakefulness, the patient presented with continuous distal arrhythmic twitches in the hands and eyelids. The EEG revealed diffuse 4-6-Hz slowwaves mixed with spike-waves on the occipital region, and paroxysmal generalized spike-waves mainly with frontal predominance during the eyes closed state. EDs with CMT disappeared upon eye opening.
> DownloadPatient 2 was a 67-year-old female at the time of EEG monitoring. During wakefulness, the patient presented with continuous, arrhythmic, mainly distal twitches in the hands at rest, with diffuse 8-10-Hz spike-waves with fast waves on EEG.
Patient 1 was a 42-year-old female at the time of EEG monitoring. During wakefulness, the patient presented with myoclonic jerks involving both the upper and lower limbs, triggered by eyes closed. The ictal EEG showed focal pseudo-periodic spike-wave activity during the eyes closed state, prevalent over the central-parietaloccipital region, as well as paroxysmal arrhythmic generalized spike-wave activity mainly on the frontal region associated with pseudo-rhythmic myoclonic activity. EDs with seizures disappeared upon eye opening.
Patient 6 was a 63-year-old male at the time of EEG monitoring. During wakefulness, the EEG showed eye-opening-related paroxysmal slow waves mixed with spike-waves, mainly in the occipital region, and eye opening was always associated with cortical myoclonic seizures. In contrast, eyes closed made the EDs and seizures disappear (note: the two channels, Fp2 and F4, are artifacts).
