I think your lobotomy timeline is off? As I understand the history, lobotomies became less common in the 1950s, once antipsychotics and antidepressants were available, and by the 1970s were rarely used. By 1984 it would not have been part of standard practice in the US.
"Not neurotypical" is a very wide category, and the vast majority of such were neither locked up nor given lobotomies.
On the other hand, ADHD kids in the 1990s were indeed forcibly medicated, as in, some schools coerced parents to give Ritalin to their child in order to attend school. IDEA 2004 included the 'Prohibition on Mandatory Medication' to prevent schools from doing that: https://www.law.cornell.edu/cfr/text/34/300.174 .
