In diagnosing ADHD some questions are critical:
- Do the symptoms and behaviors impair the child's functioning?
- Are the difficulties affecting the child's well-being in more than one setting?
- Have the difficulties lasted for a considerable length of time?
- Is the child having academic or social problems?
There are three major types of ADHD:
- Combined Type. This is the most common subtype and involves inattentive, hyperactive, and impulsive symptoms.
- Predominantly Inattentive Type. These children often lose things, forget their homework, daydream, and have trouble managing their time, planning, and organizing their things.
- Predominantly Hyperactive-Impulsive Type. This is the least common type and is characterized by restlessness and fidgetiness, but few or no problems with attention or concentration.
