The usual asylum treatments like lobotomies, electric shock therapy, blood letting, isolation and sense deprivation (being kept in small confined spaces with no sound, light, touch)

Then there is the more modern twist where the government funds 'experiments' to try and create stronger/better humans. They developed serums and such to enhance humans. Ie better eyesight, hearing, reaction times, stronger more resilient skin, faster reflexes. The serums are injected into the patients body where they want to see results. So for keen eyesight the serum is injected I to the eyes, better hearing means it's injected into the eardrums, and so on and so forth.
