The criteria for diagnosing ASD today are vastly different from those that would’ve resulted in an autism diagnosis shortly after the abolishment of lobotomy, it is hardly surprising the rate keeps going up as you widen the net.
> The criteria for diagnosing ASD today are vastly different Not that much. The difference between now and 50 years ago is that a) we don't just throw them into asylums, b) we actually have accessibility of getting diagnosed, c) employment opportunities suitable for many people with mental disabilities (such as factory line assembly) have gone down the drain.
Very much so. What we now call Autism Spectrum Disorder was referred to as "childhood schizophrenia" in the DSM-2 [1], things only started moving in the right direction with the DSM-3 [2] when it was finally sort-of recognized as an independent disorder of "infantile autism", but some core elements of ASD like sensory processing differences were only recognized in the DSM-5.
There's a good overview at [3]. It's good that criteria are different today, the criteria from decades ago failed to include majority of ways that autism expresses itself, many of which benefit from support and accommodations even though they're not obviously debilitating.
