Hello and welcome to healthcare magic!!
Take him to a neurologist
and he should be started on antiepileptic medications and the dosage of the same adjusted to suit him. once that is done and he is free from any seizure
episode for 3-5 years the doctor will get an EEG done and let you know regarding the changes in dosage or stoppage of drugs.
And what your son seems to have is complex partial seizures and not absence seizures
