there's a link between autism and family violence to my observations as well
It's my observations around mothers and children who have exited or are still in family and domestic violence. There's quite a high incidence of diagnoses of Aspergers (ASD) and/or ADHD in the children, especially boys. Also despite efforts, the diagnosing is not consistent so what one psychiatrist/ psychologist considers ASD another may consider AHDH. So I don't know whether the boys are copying violent behaviour from the father and/or expressing rage from the violence - but there's a lot of behavioural issues in them. The lone mums have a hell of a job with them.
Along with these general complaints of not feeling well, children who witness domestic violence may also appear nervous, as previously mentioned, and have short attention spans. These children display some of the same symptoms as children who have been diagnosed with attention deficit hyperactivity disorder.
Roughly two-thirds of kids with ADHD have at least one co-existing condition, and Autism Spectrum Disorders — ASD — are among the conditions that commonly occur with ADHD. Some studies suggest that up to half of kids with ASD also have ADHD
What’s the Difference Between ADHD and Autism?
ADHD is marked by inattention, hyperactivity, and impulsivity. “It is primarily a disorder of self-regulation and executive function – skills that act as the ‘brain manager’ in everyday life,” says Mark Bertin, M.D., a developmental behavioral pediatrician and the author of The Family ADHD Solution.
Autism Spectrum Disorders — a continuum of conditions that includes autism, Asperger’s syndrome (now outdated), and pervasive developmental disorder not otherwise specified (PDD-NOS) — are characterized by problems with social interactions, communication, and stereotyped (repetitive or ritualistic) behaviours.
I looked around for any research in adults and there's this The Link Between Autism and Violence Isn’t Autism where ASD can coexist with ADHD and Conduct Disorder in some, and it's the latter that leads to violence against others.
