Childhood ADD into Adult ADD • Spencer et al: 60% of children with ADHD meet criteria as adults • Spencer, Biederman, Williams: 663/1700 meet criteria • Borland and Heckman: 50% of ADHD kids meet criteria as adults as opposed to 5% of non-ADHD siblings
ADD Symptoms In College/Grad Students: • Distractibility • Organizational problems • Poor task completion • Forgetfulness • Careless errors/ trouble with details • Sequencing problems • Hyper-focusing/ Prioritization Problems • “Deer in the Headlights”
ADD in College/Grad Students (continued) • Authority Issues • Stubbornness • Intolerance of silly rules/ assignments • Relationship problems ( peer and sig. other) • Frequent changes in major/ schools • Poor frustration tolerance • Easily bored • Poor or inconsistent academic performance despite adequate or even superior intellectual abilities
What ADD College/GradStudentsReport: • Scattered • Anxious/ “Scanning The Horizon” • Irritable • Chronically Late/ Poor Time Sense • Procrastination • Bored Easily/ Restless/ Impatient • Trouble with Math/Directions • Reading Comprehension Problems • Compensatory OC Behavior
OVERWHELMED • Increase in distress/ anxiety/ disorganization when responsibility increases/ changes at work, home, or school. EXAMPLES: • Birth of child • Promotion • Increase in academic workload • Transitions: First of School Year, Starting College or Grad School, Moving Rooms, Changing Classes, Weekday to Weekend, Weekend to Weekday, Awake to Sleep, Sleep to Awake
COMORBIDITY IN ADULTS • Anxiety Disorders (50%) • Substance Abuse ( 27%-47%) • Antisocial Personality Disorder ( 12%-27%) • Affective Disorders (? %) • NO COMORBID DX: 40%
Self Rating Scales • Copeland Symptom Checklist For Adult ADHD • Brown Adult ADD Scale( BAADS II) • Amen Scale
Psychoeducational Testing • While ADHD is a clinical diagnosis, consider psychometric testing if: • Diagnosis is unclear • Accommodations are needed • More details re: exact deficits are needed or if LD is suspected.
CHRONIC vs. NEW ONSET • Childhood Prerequisite • New Onset: medical work-up indicated • Consider: endocrine, sleep apnea, drug interactions, hearing deficit, B12, head injury, heavy metal, seizure disorder. • MRI/CT, EEG, BP, EKG, baseline labs, etc.
Controversy/ Skepticism Re: ADHD in Young Adults Why? • Childhood Onset – difficult to get accurate history, especially in individuals who have IQ in superior range. • By adulthood comorbidity clouds diagnosis • ADHD is a clinical diagnosis • Schedule II medications/fear of prescribing • Countertransference/Cultural Bias
WHY NOW?( If they didn’t have trouble as small children, doesn’t that mean they are just lazy?) • Many college students functioning in the intellectual ly superior range never had to study before college • Many students had parents to manage all of their details, scheduling, deadlines, etc • Some students attended exclusive private schools with very rigid day to day routines. External organization kept them structured and limited distractions.
Compensatory Anxiety • It isn’t compulsive checking behavior if you really might forget • Anxiet y will increase catecholamines and can increase ability to attend • Procrastination creates anxiety when the work is imminently due….and can increase ability to attend • Classical conditioning model • But…too many catecholamines cause a shut down effect.
Cause and Effect • “Are you scattered because you are anxious or are you anxious because you are scattered” • “Are you depressed because you can’t get your work done or are you not getting your work done because you are depressed”
OCD and/vs ADHD • OC sxs as a compensatory mechanism. Ruminating. Lists. Excessive worry. Worst case scenarios. • Not usually repetitive over time. Tend to be day to day worries as opposed to intrusive ego dystonic obsessions • Thoughts jump from one thought to next as opposed to focusing on one obsession • Compulsive sxs are less likely to be linked to obsessive thinking.
BPAD vs. ADHD • Genetic overlap • Hyperactivity vs. Mania/Hypomania • Discreet episodes vs. ongoing symptoms
ADHDStimulant Medications Of pharmacologic options available for ADHD, stimulant medications are the: • Most studied • Most commonly used • Most effective • First-line agents for treatment Spencer T et al.

DOPAMINE/NOREPINEHRINE • DOPAMINE: mediates “verbal fluency, serial learning, vigilance for executive functioning, sustaining and focusing attention, prioritizing behavior, and modulating behavior based on social cues” (Stahl) • NOREPINEPHRINE: plays role in “sustaining and focusing attention, as well as in modulating energy, fatigue, motivation and interest” ( Stahl)
PSYCHOPHARMACOLOGYDopaminergic/ Noradrenergic • STIMULANTS: Methylphenidate (Ritalin, Ritalin LA, Metadate CR, Concerta) • Mixed amphetamine salts ( Adderall, Adderall XR), • Dextroamphetamine( Dexedrine, Dextrostat), • Dextroamphetamine long acting ( Vyvanse) • d-methylphenidate ( Focalin) • Pemoline ( Cylert)…LFT’s
PSYCHOPHARM ( cont.) ANTIDEPRESSANTS/ OTHER Buproprion ( Wellbutrin) Venlafaxine ( Effexor) Duloxetine ( Cymbalta) Desipramine/ Imipramine Modafinil ( Provigil) Clonidine ( catapress) Atomoxetine(Strattera SSRI’s for comorbidity….not for core symptoms
Problems with the stimulants Schedule II drugs (abuse liability, diversion, medicolegal concerns) 30% do not adequately respond or cannot tolerate stimulant treatment Short duration of action (compliance, embarrassment) Side effect profile adversely impacting sleep, appetite, mood, and anxiety Concerns about cardiovascular effects, growth suppression, and tic development Why Nonstimulant Treatments for ADHD?

Thoughts Re: Gifted ADHD Adults • Stimulants/ Schedule II drugs • Alteration of sense of self/ blunting of creativity • Non-linear thinkers in the academic environment. • Myth of Laziness. Twice the work for half the result. • “Left handed learners” • Responsibility • Square Pegs and Round Holes
Family Issues • “My parents and I have different ideas about what I should do after graduation. I want to go to Florence and study Art History. They want me to move into their pool house and become a dental hygienist” • Patient J, Senior at WFU
