My eldest has been getting assessed since age 3 for autism spectrum related disorders. He's super clever, laser focussed and has a lexicon that would embarass even me. They're now leaning towards a diagnosis of Asperger's / ADHD, which feels like the right fit for him as he gets fixated by topics that interest him, can be socially awkward (less so much "awkward", more over excited and intense in social situations) and can become hyper / emotional at a moment's notice as well as the aforementioned intelligence. He also can have sensory processing issues, like getting overloaded by loud noises or getting flustered and emotional if an item of clothing (for example) doesn't "feel" right to him. He's 7 now and his fine motor skills are behind his peers, but his language and numeracy skills are miles ahead, to the point he can be disruptive in class as he gets bored in lessons, plus he struggles to concentrate unless it's a topic he's interested in, then he's so engrossed he struggles to do anything other than that. Still some way to go before a final confirmed diagnosis, but I don't envisage Asperger's holding him back in life as he's very charming and witty as well as smart as a whip, so hopefully the hyper / emotional edges will round off with time and make him that bit happier overall.
