I have quite a few saved charts for Austism, but I haven't yet been able to go through them to find a common thread.
I do think however, most will have a conjunction or other aspects between
Uranus, Neptune, Saturn and Mercury.
Here are a few while I look through my files you can think on these:
Kyron: Mercury 11Libra Seisquadrate to Uranus (processes information differently perhaps)
Mercury Trine to Neptune (dreaminess) and is in sync with dreams
Mercury Sextile to Jupiter
George & Sam (a book you can find on the internet or Amazon about 2 autistic brothers in Sussex England, or perhaps in your library.
The times of birth were given in the book by the mother.
Amazon.com: George & Sam: Two Boys, One Family, and Autism (9780312358938): Charlotte Moore: Books
Severely autisic as I recall both of them although one was violent and one was more placid.
George was born : 1/26/90 and his brother Sam 11/19/91
so they are not twins and have a healthy sibling, another 3rd boy who is younger then they are.
George: Mercury 1t 17SAG conj. Uranus 12 SAG and Uranus is in a stellium so conjunct to Neptune and Saturn as well.
Also, George has Mercury conj. Neptune (floats off to dreaminess) similar perhaps to Kyron who has been already described as such by the grandmother.
Sam Mercury is 18SAG (note the same Mercury as his older brother)
square Jupiter at 12Virgo Mercury semi-square to Saturn conj."Altair"
(within one degree) in Aquarius 1°
Uranus is Trine to Jupiter, Uranus is conjunct Neptune
Then there is the recent case here of Nadia Morgan, the little girl who wandered off her bicycle in Florida and was in the swampy area near her home for 3 nights and was miraculously found by a church member looking for her after the LE and others could not find her.
Nadia Morgan Bloom : (her chart should be here somewhere on the threads)
but you can refresh your memory here on this link about her case:

Mercury 22Leo (Bi-Quintile) a creative aspect to her thinking, which would process information differently is BiQ to Jupiter. The Quintile and BiQuintiles are thought to be aspects of creativity, so
perhaps aided her when she was lost to survive best she could.
Her
Mercury is also Rx at birth
Her Uranus is square to Saturn and semi-square to Jupiter
Her Neptune is square to Saturn
Was reported to be "somewhat" autistic.
