OBJECTIVE: In this study, our aim was to demonstrate the effect of sleep deprivation, short sleep, and awakening on photoparoxysmal responses (PPR) and eyelid myoclonia (EM) in patients with Epilepsy with Eyelid Myoclonia (E-EM).
METHODS: E-EM patients with at least 1 year of follow-up in our clinic were included in the study. Video EEG(v-EEG) analyses were divided into three periods of wakefulness, sleep, and awakening. The PPR and onset of EMs were investigated.
RESULTS: 32 patients met the study criteria, of which 56.3% (n = 18) were male. The mean age at disease onset was 7.7 ± 4.1 years. The mean age at EEG recording was 12.4 ± 4.0 years. EM was observed only on awakening in 78.1% of patients (n = 22), of which it was seen only during intermittent photic stimulation (IPS) in 43.7% (n = 14). Eye closure (EC) sensitivity was detected in all patients. The proportion of patients with a PPR was significantly higher on awakening than before sleep (p = 0.01).
CONCLUSIONS: This study showed that EM is most prominent and sometimes can only be detected in the awakening period in E-EM. In order to detect E-EM, v-EEG recordings including both pre-sleep and post-sleep wakefulness periods should be recorded, with intermittent photic stimulation performed in both periods.
