OBJECTIVES

At the conclusion of this educational presentation, the participant will be able to:

- List admission criteria for ADHD in children and adults. - Describe proposed neurobiological basis for ADHD. - Identify risks factors predisposing patients to ADHD. - Name pharmacological and non-pharmacological treatments for ADHD.

ATTENTION DEFICIT HYPERACTIVITY DISORDER

? A brain disorder marked by an ongoing pattern of

inattention and/or hyperactivity-impulsivity that interferes with functioning or development.

BASED ON TYPES OF SYMPTOMS

Three kinds of presentations

? Combined Presentation: if enough symptoms of both criteria

inattention and hyperactivity-impulsivity were present for the past 6 months

? Predominantly Inattentive Presentation: if enough symptoms

of inattention, but not hyperactivity-impulsivity, were present for the past six months

? Predominantly Hyperactive-Impulsive Presentation: if

enough symptoms of hyperactivity-impulsivity but not inattention were present for the past six months.

? Symptoms may be classified as mild, moderate, or severe based on

symptom severity

ADHD

? A disorder of inefficient "Tuning" of the prefrontal cortex by dopamine and

norepinephrine

? ADHD patients do not activate prefrontal cortex areas appropriately in

response to cognitive tasks of attention and problem solving (executive functioning).

? Firing of NE neurons innervating the prefrontal cortex is too low ? Low NE tone hypothetically contributes to the cognitive dysfunction in

ADHD.
