April is Autism Awareness Month.
Autism refers to a spectrum of developmental brain disorders. It is currently estimated that 1 in 110 US children are diagnosed with autism spectrum disorders (ASD). Autism is more prevalent in males; in the US alone, about 1 in 70 boys are diagnosed with this disorder. Unfortunately, it isn't yet known what causes autism spectrum disorders.

On a related note, one of my favorite books is The Curious Incident of the Dog in the Night-Time by Mark Haddon. We were discussing this at work the other day, and it ties in with Autism Awareness Month. Although Mark Haddon doesn't explicitly state in the novel that the main character, Christopher, has ASD, it is pretty safe to assume he does. Christopher is a 15 year-old child with behavioral and social issues who resorts to solving mathematic equations and groaning when overwhelmed or upset. He does not like the color brown or when people touch him. The story is told from Christopher's perspective, and each chapter is assigned its own prime number. It's a good read, and I highly recommend it! I think it might be time for a reread for myself as well.
