The Asperger's might have been there all the time but the medication made you unable to cope. Something similar happened to me, only in adulthood - the drugs I was taking made me unable to mask and cope, and generally pass for normal as I did for most of my life.
Or the age when the traits started to be visible happened to be when you were taking the drugs.
Or you don't have Asperger's but the drugs in your childhood messed up with your social development - in this case it maybe could be reversed by a good psych.
In either case, the doctor and your parents did really awful job to you.
