Are the any medications that ease the traits of ASD
Not really, no. Some people claim to have found benefit from some probiotics, or B6/magnesium.
For sleep problems, melatonin. For anxiety, anxiolytics (herbal or drugs).
There is some limited evidence of giving oxytocin to children, or for social issues sulforaphane (found in broccoli sprouts and brassicas) - https://www.pnas.org/doi/10.1073/pnas.1416940111
I don't know of any treatment with really good evidence behind it.
