Key Facts
1. ADHD tends to
run in families and, in most cases, it's thought the genes you inherit from
your parents are a significant factor in developing the condition.
Research shows
that parents and siblings of someone with ADHD are more likely to have
ADHD themselves.
However, the way ADHD
is inherited is likely to be complex and is not thought to be related to a
single genetic fault.
Research has
identified a number of possible differences in the brains of people with ADHD
from those without the condition, although the exact significance of these
is not clear.
For example, studies
involving brain scans have suggested that certain areas of the brain may
be smaller in people with ADHD, whereas other areas may be larger.
Other studies have
suggested that people with ADHD may have an imbalance in the level of
neurotransmitters in the brain, or that these chemicals may not work
properly.
