When a child has ADD ADHD, it is not uncommon for the first person to recognize the symptoms to be the child’s teacher. Many of the symptoms of ADHD can seem more pronounced in a structured classroom setting, when a child is forced to sit still and focus on something specific. Of course, a teacher’s suspicion is not grounds for assumption that your child has the condition. A diagnosis of ADHD should come only after valid ADHD assessment tests and extensive professional evaluation that includes such factors as his or her behavior at school, at home and at play, and that eliminates the possibility that your child is suffering from other conditions, such as depression or anxiety, that can produce similar symptoms.
