The diagnosis of ADHD requires gathering information from multiple sources like the child, parents, teachers and physicians to assess symptoms like inattention, hyperactivity and impulsivity. A doctor takes a medical history to understand how long symptoms have occurred and their impact, as signs of ADHD may first be noticed before school when a child has trouble focusing, becomes easily distracted and lacks self-control.

2. How Is ADHD Diagnosed?
• The process of diagnosing ADHD requires several steps and
involves gathering a lot of information from multiple sources.
You, your child, your child's school, and other caregivers
should be involved in assessing your child's behavior.
• A physician can conduct a medical history to help put a child's
behavior in context. They will ask what symptoms a child is
showing, how long the symptoms have occurred, and how the
behavior affects a child and his/her family.

3. • The signs of possible attention deficit disorder may first
be noticed long before the child begins school. Their lack
of attention, hyperactivity, and impulsivity may be seen
when these lose interest in playing a game or watching a
TV show, or if the child runs around and seems
completely out of control.
