My son, Nathan, is 22 months old now and has just last night and then again today had some short-lived seizure type of episodes. He sorta goes "absent" for 10-15 seconds and then comes out of it a little bit spacey, or sometimes comes out of it a little bit hyper.

We're out of town ( visiting Arcada, California ) and had a trip to the ER today - they found nothing much and honestly didn't give us much insight at all into what might be going on, or what we should be doing.

Here's a brief synopsis of what I've found on the internet back at the motel tonight:

Possible causes
--------------------------------------------
Fever
Virus
Celiac disease ( wheat/grain allergy )


Ruled out possible causes
--------------------------------------------
Sleep Myoconus -- NOPE - NOT THIS


Suggestions
-------------------------------------------------------------------
Write down/keep track of what he eats and when the episodes come
Don't leave him alone at all in the bath

Absence Seizures ( petit mal ) - short episodes during which the child stares or eye blinks,
with no apparent awareness of their surroundings. These episodes usually do not last longer
then a few seconds and start and stop abruptly; however, the child does not remember the event
at all. These are sometimes discovered after the child's teacher reports daydreaming, if the
child loses his or her place while reading or misses instructions for assignments.
