  • Slide 13 - What is ADHD in adults? The same two symptom dimensions as in children: Hyperactive-Impulsive Inattentiveness
  • Slide 14 - Hyperactive-Impulsive often fidgets with hands or feet or squirms in seat, often leaves seat in classroom or in other situations in which remaining seated is expected often runs about or climbs excessively in situations in which it is inappropriate (in adolescents or adults, may be limited to subjective feelings of restlessness).”
  • Slide 15 - Hyperactive-Impulsive often runs about or climbs excessively in situations in which it is inappropriate (in adolescents or adults, may be limited to subjective feelings of restlessness).”
  • Slide 16 - Hyperactive-Impulsive often has difficulty playing or engaging in leisure activities quietly, is often ‘on the go’ or often acts as if ‘driven by a motor,’ and often blurts out answers before questions have been completed

  • Slide 21 - All present since childhood
  • Slide 22 - What are the neuropsychological basis for these symptoms? 10 years ago this was quite clear, but not any more There are no psychological tests which all adults with ADHD do poorly on. The neuropsychology of ADHD is so heterogeneous that some patients do poorly on just about any test
  • Slide 23 - Psychological tests can not diagnose ADHD. Nevertheless, the more executive function problems, the worse the academic and occupational outcome:
  • Slide 24 - Executive dysfunction Organization and planning Working memory deficits The ability to hold information “ïn your mind” so you can compare scenarios, solutions, and consequences
  • Slide 25 - Executive dysfunction Response Inhibition Problems Can’t resist an impulse to move, act, or think while on another task Sustained attention Shifting/Mental Flexibility Interference control
  • Slide 26 - What are functional deficits in ADHD in adults?
  • Slide 27 - Occupational and Academic More dropouts, lower occupational achievement More likely fired More likely to quit More bankruptcies Not as wealthy

  • Slide 33 - Genetic 75% heritability, but no one gene causes this 50% of children of ADHD patient will have some signs of ADHD
  • Slide 34 - Biological Adversity Prematurity Smoking or drinking in pregnant mother Food additives? Obstetrical Complications
  • Slide 35 - Psychosocial Adversity Poverty Single parenthood Social class Chronic family conflict Low family cohesion Exposure to current, not past, parental psychopathology Abuse

  • Slide 37 - What looks like ADHD but isn’t? Other toxins Horrible home issues Neurodegenerative On and on………..
  • Slide 38 - How does it classically appear? Parents of clearly diagnosed patients of yours with ADHD Pearl: if someone has three or more children and none of them have ADHD, probably the parents don’t either. Clearly diagnosed ADHD children grown up.
  • Slide 39 - How does it present? About 1/3 will still be disabled as adults, with very few growing out of it after age 30. Addiction Treatment Centres and follow up Depending on the centre, 25-35% of the people in treatment programs have ADHD, too. Severe accident follow up
  • Slide 40 - Hyperactive in a wheelchair or rehab unit?
  • Slide 41 - When should you be very suspicious that this is not ADHD? Stable family life, occupation, and just psychological distress New onset problems as adult
  • Slide 42 - When should you be very suspicious that this is not ADHD? Come in on their own – not brought by spouse, friend, parent, etc Have a list of questions and an organized presentation of their history
  • Slide 43 - Treatment
  • Slide 44 - Three equally challenging issues
  • Slide 45 - Compliance Missed appointments Drop ins script refills lost prescriptions vs. diversion
  • Slide 46 - Dealing with the illness Dealing with the financial, legal, familial, and physical sequale Dealing with having a chronic psychiatric illness Dealing with comorbid disorders
  • Slide 47 - Psychotherapy Few trials, but the only success stories so far are for skill training with modules on organizing and planning, distractibility, adaptive thinking, and procrastination this one has been used in a double blind trial of persons who were treated with medications and partially responded.
  • Slide 48 - This is the manual from that study and a copy is on the table
  • Slide 49 - This is the therapist manual - copy on the table
  • Slide 50 - Medical Treatment of ADHD in Adults First step is to match the drug to the person, given that almost everyone will have some comorbid problem.
  • Slide 51 - Medications
  • Slide 52 - Stimulants Work immediately
  • Slide 53 - Short acting Stimulants Good points: Most potent of ADHD medications Bad Points: Abusable need to take three times a day can cause depression High street value in academic settings
  • Slide 54 - Short acting Stimulants Good choice for: extremely reliable persons with ADHD that doesn’t respond to long acting drugs with no history of substance abuse or depression Dose is 1mg/kg – about 20-30 mg tid of Ritalin or 10-20mg tid of Dexedrine. No insurance
  • Slide 55 - Long Acting Stimulants Good points: once a day and potent. not abusable Bad points: need to take it before 9am still can cause mood disorder doesn’t cover late night High street value in schools and University
  • Slide 56 - Long Acting Stimulants Cost for concerta and Adderall can be over 200 dollars a month at high doses, which are often the case in large persons. Dosages Concerta and biphentin: roughly 1mg/kg, Adderall roughly .5 mg/kg, Dexedrine Spansules, .5mg/kg,
  • Slide 57 - Non-Stimulants All work on the time frame of antidepressants – 8 weeks.
  • Slide 58 - Strattera- Good points 24 hour coverage, once a day Not abusable May help comorbid anxiety
  • Slide 59 - Strattera- Bad points Not that potent Still can cause mood disorders expensive- over 270 dollars a month for full doses. Dosage – start at .5mg/kg, increase to 1-1.2 mg/kg
  • Slide 60 - Welbutrin Good points Also an antidepressant Unlikely to cause depression Decreases smoking Can be combined with stimulants Works all day
  • Slide 61 - Welbutrin Bad points Not that potent Dosages -300mg/d Seizures with Bulimia, Pot
  • Slide 62 - Alertec (Provigil, Modafinil) Good points: Works all day Not abusable Bad points: Not that potent More GI side effects Not that cheap: 200 dollars a month Dosages 200-400 mg/d
  • Slide 63 - Drugs that do not work: Effexor SRIs Atypical antipsychotics Mood stabilizers Nicotine patch cannibis
  • Slide 64 - Realistic outcomes Three main possiblilties:
  • Slide 65 - Most likely outcome Non-compliant – miss appointments, forget scripts
  • Slide 66 - Next most likely outcome Combination of side effects and improvement usually balancing insomnia, depression, and effect. Or doesn’t cover enough of the day. Usually has less effect on higher level problems in my experience: organization, time management, procrastination
  • Slide 67 - Least likely outcome Completely transforms their life with minimal side effects
  • Slide 68 - A realistic approach Step 1. proper diagnosis is made ( one visit)
  • Slide 69 - A realistic approach Step 2. patient actually comes back a second time to discuss treatment and life management issues with some other responsible adult( tests whether they really can come back)
  • Slide 70 - A realistic approach Step 3. Start medication with the understanding that most likely skills training will be needed or couple script with skills training. “Assuming the drug does not work miracles, you will need extra help learning some new skills”
  • Slide 71 - A realistic approach Step 4. Monitor comorbid problems
  • Slide 72 - Do not: Refill scripts before they are due for stimulants, no matter what the reason Refill scripts without the patient coming in more than once in a row
  • Slide 73 - Do not: Hesitate to link scripts to drug screens Give stimulants directly to patients who live in dormitories Get too focused on trying to find the magic drug.
