What Dr. Eilenberg says is pretty relevant considering the issue is a letter sent to Lakewood chadarim.
(Not as relevant in the greater scheme of things.)
NDG, would you like to compare how many patients Dr. Shanik has seen in his life with how many seen by Dr. Eilenberg?
The bottom line, though, is what Syag said, that who gets autism (as well as all conditions and diseases l”a) is decided by the RBS”O. We need to do our normal hishtadlus, but bucking the widely conventional medical wisdom based on anecdotes and conspiracy theories is not normal hishtadlus.
