Video EEG samples from two women with Jeavons syndrome.^35;130

Top: Brief GSWD with similar characteristics are induced by IPS (left) or eye closure (right). They occasionally occur spontaneously (middle). In all illustrated occasions, these GSWD were associated with marked eyelid myoclonia denoted by various symbols. Also note that there is no impairment of counting (numbers).

Middle: Repetitive discontinuous seizures of eyelid myoclonia occurred on awakening when the patient was erroneously treated with carbamazepine. These lasted for more than half an hour. There was only mild interruption of speech and counting during the GSWD. The patient was fully aware of her condition.

Bottom: Long video EEG of a woman with Jeavons syndrome while taking valproate. There were frequent eye-closure related GSWD of mainly polyspikes, often associated with fast eyelid jerking, which could be mild or violent. The GSWD occurred only in the presence of light. They were totally inhibited in complete darkness (complete darkness implies that any form of possible light was totally eliminated). Symbols of eyes indicate when the eyes were open or closed.
