Absence
seizures (formerly petit mal)
Absence seizures can appear
to observers as though the child is daydreaming or switching
off, something we all do when our mind is wandering. Because
absence seizures may be hard to distinguish from the child's
usual behaviour, they may be difficult to detect. They can occur many times a day and are
often mistaken for daydreaming.
In MAE, absence seizures
occur in more than one half of the cases. These absence seizures
often accompany myoclonic seizures, especially clusters of
myoclonic and / or myoclonic-astatic seizures. If these seizures
occur frequently throughout the day, they can interrupt the
child's ability to function properly because his/her awareness
(and the brain's processing) is being constantly interrupted.
What happens?
Like all of the generalised
seizures, an absence seizure starts suddenly and without
warning. The child displays a glazed look and stares.
Sometimes there is mild twitching of the mouth, eye blinking, or
barely noticeable head bobbing which may give the observer a clue
that seizure activity is occurring. The event usually lasts only
seconds, sometimes 15-30 seconds or perhaps longer, and ends
just as abruptly as it started. These events may be so brief
that they are observable only on the EEG. When the seizure ends,
the child is immediately alert and there is no confusion
afterwards. However the child will have missed some of what is
happening around him/her.
As is the case with all
generalised seizures, the child is momentarily unconscious
during the event so he/she doesn't know what is happening,
cannot recall anything, is unresponsive and no level arousal
will bring them around until the seizure is finished.
