The child with hyperactivity may:
* have problems concentrating and paying attention.
* find it hard to sit still in class - and keep wiggling around in their seats or get up and move around a lot
* talk too much
* interrupt other people's conversations
* yell out the answers the other children have a chance to raise their hands.
* be disorganized, distracted, or forgetful.
* lose things
* have trouble finishing anything.
Some children with ASD are also hyperactive.
In some cases such behaviour is linked to:
* Food intolerances especially to casein (milk) and/or gluten (wheat) or to particular foods (from chocolate to oranges and even carrots).
These can cause hyperactivity or disruptive behaviour – often within one or two hours of eating - but because the the effects are generally behavioural rather than physical the link is often overlooked.
Such behaviours may also be worsed by hypoglycaemia - which can lead to agitation either prior to meals or after eating sugary foods.
Keeping a food diary will help you assess if such things contribute to his behaviour
