These diagnoses are labels for a collection of behaviours that tend to be at odds with the way schools function.
Children show a lack of patience and perseverance, often with a tendency to interrupt and want things to happen NOW. They are impulsive, and find it difficult to stay focussed, so that tasks are unfinished. Inattention, taking risks and those with ADHD are unable to be still and this can be an annoyance to others. Their responses to correction are often emotional and get them in to more trouble!!
Alongside these general behaviours there may be many underlying problems with self organisation, inability to be at rest in any way, non-stop talking and movement, difficulty staying on task and lack of self value. It looks like over stimulation, but it is in fact a shortage of dopamine. The stimulation of a video game can be highly attractive!
However, it is possible to have some of these features and not others. Each feature relates to a persistent infant reflex or combination of reflexes. So we can target the problem for each child according to their reflex profile.
