Why did patients apply to this trial?

My anxiety and depression are bad. Looking for solutions that will help my son with his ASD.
PatientReceived no prior treatments
My son, Tristan, has tried all the ADHD medications with no luck. We need help to improve his mood, anxiety, and ADHD symptoms.
PatientReceived 2+ prior treatments
My adult autistic son has been agitated a lot lately. It comes and goes, but it is scary when it happens. He self-harms. He used to harm me. His father died recently, at age 48, out of the blue, in his sleep while our son was visiting. And my mother lived with us until her Alzheimer's got too bad. She also died recently. We've tried typical anti-psychotics, both of which made him actually psychotic. He needs help that will help. Plus, he loves to go to see doctos, so even if it is placbo, he will have some fun.
