Your child may have very poor organisational skills, they can be very messy and lose their posessions regularly.
Their memory is also patchy and they can have difficulty sitting down and applying themselves to tasks.
You may think that these are just normal children behaviour, but the difference between children with ADHD and non-ADHD children is that a child with ADHD does not seem to be able to follow instructions or learn from their mistakes.
In addition to those ADHD can impair your child’s social skills. CHildren with ADHD usually have a lot of difficulty making and maintaining friendships due to their lack of empathy and inattentiveness to social cues.
