excessive eye blinking

[Jillmad]

Reason why a boy of the age 9 suddenly started excessive eye blinking? What could be the cause; could it be infection, lack of sleep, dry eyes, change of schedule, nervousness, and/or tics? I’ve made an appointment with eyes specialist and was hoping for some insight.

You need to have an EEG done because it could be small seizure activity.

Need to obtain evaluation from pediatric opthalmologist to rule out serious eye problems.  But sounds like a form of an eye tic (there is a technical name for which I cannot recall).  The eye forum will likely be of help.
