Overview • What Is AD/HD • What Causes AD/HD • How Common • Common Symptoms • Common Treatments • Comparison with Conduct Disorder
What has it been called • First called minimal brain damage • Afterwards called minimal brain dysfunction • Next called ADD • Finally called ADHD
What is AD/HD? …A medical condition characterized by inattention and/or hyperactivity-impulsivity. …One of the most common mental disorders among children, affecting approximately 5 to 7 % of school-age children and about 2-5% of adults
What is AD/HD? • Persistent inability to pay attention • May have additional characteristics of hyperactive motor movements and/or impulsivity • Usually begin before age 7 but may not be noticed until child is older
What is AD/HD • Symptoms of inattention and/or hyperactivity must be present in at least two environments • Symptoms must cause problems for the individual in their environment
What causes AD/HD? • Decreased amount of certain neurotransmitters • There may be a genetic association • Appears more often in children whose parents suffer from AD/HD, alcohol dependence and/or mood disorders
Pathophysiology • Delayed in frontal and temporal lobe • Accelerated maturity of the motor cortex • SPECT shows reduce circulation • Pet Scan shows a decrease glucose metabolism during activity
ADHD Throughout the Lifespan • Preschool- Disruptive behavior, aggression towards other children, hyperactivity, conduct problems, inattentive and overactive • Middle Childhood- Unfinished tasks (unfinished games, uncovered toothpaste), trouble with school work, criticism from parents/teachers/peers, low self esteem. Depression and conduct disorders can develop here.

Percent of Youth 4-17 ever diagnosed with Attention-Deficit/Hyperactivity Disorder: National Survey of Children's Health http://www.cdc.gov/ncbddd/ADHD/adhdprevalence.htm
Percent of Youth 4-17 ever diagnosed and currently medicated for Attention-Deficit/Hyperactivity Disorder: National Survey of Children's Health http://www.cdc.gov/ncbddd/ADHD/adhdmedicated.htm
Prevalence in the US • About 2 million children • About 5 million adults
Prevalence World-Wide Australia 3.4% of kids New Zealand 6.7% kids, 2-3% teens Germany 4.2% children India 5-29% children China 6-9% children Netherlands 1.3% teens Puerto Rico 9.5% child & teens Japan 7.7% children Mexico approx. 5% childrenBrazil 5.8% of 12-14 year olds
How common is AD/HD? • More common in males than females with studies showing a ratio of between 3:1 and 4:1 • As many as 5 out of every 100 children may have AD/HD
What are the signs of AD/HD? • Three main symptoms (signs) • Problem paying attention (distractibility) • Being very active (hyperactivity) • Acting before thinking (impulsivity)
Based on the these criteria, three types of ADHD are identified: 1. ADHD, Combined Type: if both criteria A and B are met for the past 6 months. Tigger type-Hyperactive, restlessness, disorganized, inattention, impulsivity
2. ADHD, Predominantly Inattentive Type: if criterion A is met but criterion B is not met for the past six months Pooh type- Inattentive, sluggish, slow-moving, unmotivated, daydreamer
3. ADHD, Predominantly Hyperactive-Impulsive Type: if Criterion B is met but Criterion A is not met for the past six months. Rabbit Type- over focused, obsessive, argumentative
ADHD NOS ADHD, NOS is a category for people who have some ADHD symptoms, but not enough to meet full criteria for the condition.
