I really don't think sliding down a rail is a good excuse to say someone has Austim...kids younger than that have done it. Some of the stuff Lincoln does complain about is legit to an extent however, and often times, people do things without thinking them through. That doesn't apply to just Autistic people, and I have a couple friends who have it. The reason I see Leni having ADHD is because of her short attention span, being easily fooled, takes things oddly literally (like the times Lori asked her to make her bed, as in rearrage the sheets. The blonde LITERALLY made a bed frame from scratch. Not to mention the time she thought the kitchen was some 2 miles from the house, and she's lived there her whole life...) After having done some thorough research while doing chapter 11 of Syngenesophobia, Leni definitely has some attention deficit issues but, unlike ADD, she's not really moody about it. Plus, she's pretty active most of the time and happy, but no 16 year old is THAT dense without having some sort of brain issues. I just don't think it's Autism.

However, with Lisa, I think she does have some form of Autism because of her unnaturally high IQ at her age. Took some searching for clues on that, but some cases have pointed to Autism resulting in higher than average intelligence in some people.
