The Problems :The Problems ADHD as classically defined Other Executive Function problems Co-Occurring Problems of the Syndrome Mix Family Problems


The goal of laying out the problems of the Syndrome Mix: :The goal of laying out the problems of the Syndrome Mix: “Okay, my kid has a short attention span, but why does he/she…?”


Our task :Our task Sort out: co-occurring mimicking exacerbating. Unless you identify, you cannot discuss or treat.


Depressing? :Depressing? Neurological basis Not the child’s “fault.” Not the parents’ “fault.”


Neuroanatomy of ADHD :Neuroanatomy of ADHD MRIs of ADHD group demonstrated smaller: Frontal cortex Subcortical areas (striate: caudate, putamen, gp) Striate-frontal paths involved with: motor control executive function inhibition of behavior modulation of rewards. Rich in catecholamines


Functional Neuroimaging :Functional Neuroimaging PET and fMRI (measures neuronal use of deoxyhemoglobin) suggest: Prefrontal abnormalities Disturbed dopamine activity


D4 receptor in ADHD :D4 receptor in ADHD Strongest association with 7 repeat allele of the dopamine D4 receptor gene (DRD4).


Neurophysiology of ADHD :Neurophysiology of ADHD Too little NE driving the frontal lobes. “Frontal lobe brakes haven’t been woken up.” Too little DA from frontal inhibitory projections onto the striate. “Frontal lobe brakes are weak.”

ADHD:The Traditional, Boring Definition :ADHD:The Traditional, Boring Definition Triad of: Inattention Hyperactivity Impulsivity


Six or more symptoms of inattention :Six or more symptoms of inattention (a) fails to give close attention; careless mistakes (b) difficulty sustaining attention (c) does not seem to listen when spoken to directly (h) easily distracted by extraneous stimuli (e) difficulty organizing tasks (d) fails to follow through (not volitional/incapable) (f) avoids tasks requiring sustained organization (g) looses things needed for tasks (i) often forgetful in daily activities

DSM: 3 Types of ADHD :DSM: 3 Types of ADHD ADHD, Predominantly Inattentive Type ADHD, Predominantly Hyperactive-Impulsive Type ADHD, Combined Type


Typical, Boring and Useless Description of ADHD :Typical, Boring and Useless Description of ADHD “Johnny is very active! He never stops moving. He gets distracted by any little noise, and has the attention span of a flea. Often, he acts before he thinks. His sister, Jill, is often in a fog. Sometimes, she’s just so spaced!”


More Accurate Description :More Accurate Description “I can’t take it any more!! We scream all morning to get out of the house. Homework takes hours. If I don’t help him with his work, he’s so disorganized that he’ll never do well. If I do help him, he screams at me. Since he never finishes anything, everyone thinks he doesn’t care….


Slide 19:No matter how much we beg or punish, he keeps doing the same stupid things over and over again. He never considers the consequences of his actions, and doesn’t seem to care if they hurt me. It’s so easy for him to get overwhelmed. Sometimes, he just wants to ‘turn the noise off….’


Slide 20:He is so inflexible, and then blows up over anything. It gets me so angry that I scream back, which makes everything even worse. Now that he’s getting older, the lies and the cursing are getting worse, too. I know he has trouble paying attention, but why does he have all of these other problems as well?”

New Concept of ADHD: A Problem with Inhibition :New Concept of ADHD: A Problem with Inhibition There is deficient frontal and pre-frontal lobe function in ADHD. These pre-frontal lobes are the home of our executive and braking functions. ADHDers show executive dysfunction and brakeless behaviors.


New Definition of ADHD :New Definition of ADHD The inability to inhibit the present with an eye to the future. –Russell Barkley “Living RIGHT NOW!!!”


This is what Jack sees: :This is what Jack sees:


This is what Mom sees: :This is what Mom sees:


Executive Function (EF) (Russell Barkley) :Executive Function (EF) (Russell Barkley) Frontal lobe (executive) functions: Inhibition (brakes) Orchestrating the brain (CEO) Self talk Working memory FORESIGHT Hindsight Shifting agenda Separating emotion from fact


Inhibition / Brakes :Inhibition / Brakes Most basic EF is putting on brakes. We need to be able to inhibit distractions/impulses/hyperactivity (can play video games) Unless we stop first, never get to use other EFs.


CEO :CEO “Self” is a barely coherent collection of parallel processes. When speech or memory centers used, we become aware. No one is in charge. Frontal lobes try their best to orchestrate.


Self-Talk :Self-Talk Toddlers do it out loud. ADHDers never get to practice. ADHDers don’t internalize self talk. ? poor problem solving.


Working Memory :Working Memory What we can juggle electrically. 512 megs RAM Need to access past, present, and future simultaneously. Not exercised without brakes in ADHD.


Foresight :Foresight Ability to predict and plan for the future. Poor without ability to inhibit present or keep the future in working memory. ADHD: prisoners of present. Poor foresight is perhaps greatest disability of ADHD. (Mothers typically have great foresight.)


Foresight :Foresight


Hindsight Sense of time :Hindsight Sense of time Ability to recall success of past strategies. ADHDers don’t learn from their mistakes! Extremely poor in ADHD. Poor estimates. Time moves too quickly. Time moves too slowly.


Shifting Agenda :Shifting Agenda Switching requires sustained effort and control. Difficult in ADHD. Kids need warnings.


Separating Emotion from Fact :Separating Emotion from Fact Every event has: Objective reality (ex: traffic jam) Emotional tag Separating the two requires time to reflect. Result is poor ability to judge significance of events.


Actual Symptoms of Executive Dysfunction :Actual Symptoms of Executive Dysfunction Distractible Inadequate inhibition of extraneous stimuli. Impulsive Inadequate inhibition of internal stimuli. Hyperactive Physically checking out those stimuli.


More symptoms: Audience: This is IMPORTANT :More symptoms: Audience: This is IMPORTANT Lack of foresight [Shooting self in foot vs. lazy] Poor hindsight [How many times punished; help at the time] Live at mercy of moment [4 second rule] Poor organization [back for books] Trouble returning to task [never finish. Don’t care?]


Other Symptoms of Executive Dysfunction :Other Symptoms of Executive Dysfunction ·  Poor sense of time [2 hr consult] ·  Time moves too slowly [Shopping] ·  Poor ability to utilize “self-talk” [think thru?] Poor sense of self awareness [A: not a clue] · Poor reading of social clues [weird]


Still More Symptoms :Still More Symptoms ·  Trouble learning from mistakes ·  Inconsistent work and behavior [Hold against] ·  Trouble with transitions [Curse for dinner] ·  Hyper-focused at times [off computer] ·  Poor frustration tolerance [why not let us help?] ·  Frequently overwhelmed [Stop!]


And Still More Symptoms… :And Still More Symptoms… ·  Gets angry frequently and quickly ·  “Hyper-responsiveness” [Sprinkles] ·  Inflexible/explosive reactions [Stuck/break] ·  Feels calm only when in motion [work] ·  Thrill seeking behavior [top in emergency] ·  Trouble paying attention to others Trouble with mutual exchange of favors. Sense of failure to achieve goals.

Summary of Drug Actions :Summary of Drug Actions


Sources :Sources Russell Barkley: Taking Charge of ADHD Hyperactive Children: A Handbook Ross Greene: The Explosive Child


Sources, cont’d. :Sources, cont’d. Chris Dendy: Teenagers with ADD: A Parents’ Guide Thomas Phelan: All about ADD Surviving Your Adolescents Family 18 years on the job


Keep It Positive :Keep It Positive Celebrate ADHD strengths: “Why not?” attitude Energy Creativity Communicate that you believe in the child. Criticize/Hate ADHD, not the person.


Keep It Positive :Keep It Positive Instead of punishing bad behavior, encourage good response to replace it. (Barkley) Redirect rather than punish. Only positive reinforcement changes behavior and attitude. Don’t mock. Need subtle corrections.


Positive: Bank Account :Positive: Bank Account Imaginary bank account of good/bad times. Keep the bank account positive. Laugh/hug. Spend time together without being annoying! Accept apologies. Take the good times as they come. Find something to praise.


The “No Fault” Approach(Zeigler-Dendy) :The “No Fault” Approach(Zeigler-Dendy) Avoid arguments based on “whose fault.” This is the rule. It was broken. This is the pre-set consequence. I feel your pain.


Benefits of No Fault :Benefits of No Fault Avoids arguments. Good with people who refuse to accept blame. (There is no blame.) Allows us to criticize the behavior, not the child. Might occasionally be unfair, but good in the long run.


Nice Traffic Cop :Nice Traffic Cop Imagine you get pulled over for speeding. The policeman gives you the ticket AND starts calling you lazy and worthless…. When we hand out the punishments, let’s leave the nasty comments behind.


Phelan’s 4 Cardinal Sins :Phelan’s 4 Cardinal Sins Don’t nag. It hasn’t worked yet. Don’t lecture. Ditto. “Insight transplants” don’t work. Don’t argue. It takes two. Don’t offer unscheduled advice. I.e., if it’s not useful, don’t do it.


Maintain a Disability Outlook (Barkley) :Maintain a Disability Outlook (Barkley) Cuts through “blame.” Parents become “therapists” not “victims.” Realistic outlook minimizes frustration. Frustration occurs when outcome expectations ADHD does not define the child: you can still celebrate the good parts of ADHD and the person!


Seek to Understand :Seek to Understand Model listening and re-phrasing. Ask question: “Why did he do that?” Answer: “What would someone do if they could only see 4 seconds into the future?” It’s their disability. Don’t take it personally. You just happen to be there.


Let the Teen Be a Partner :Let the Teen Be a Partner Let teen be involved. Give choices ? empowerment Negotiate. No other choice. Model seeking “Win/Win” solutions. Parent gets final stand. ADHDers love to think it’s their idea.


Plan A: Token/Reward Systems(Barkley) :Plan A: Token/Reward Systems(Barkley)


Criteria for Behavior Mod. :Criteria for Behavior Mod. Worth changing. Under child’s ability to control. It’s the child’s problem. The reward system is likely to work. Cooler heads can apply it


Reward/Token Systems :Reward/Token Systems ADHDers are moths. Make brightest light productive. Bribes= illicit behavior (besides, appeal to ethics hasn’t worked). Frequent, strong, immediate feedback. Rewards need rotation. Rules reviewed before needed.


Reward Systems :Reward Systems Keep punishments short, immediate. Avoid spiraling threats/punishments. Goal is correction for “next time,” not sadism. Difficult to maintain. Best with elementary age children.


Slide 86:Most children respond to enticements/threats. Your child probably isn’t one of them. You’re ready for:


Plan B :Plan B Dr. Ross Greene The Explosive Child


Plan B:Behavior modification via staying calm to prevent “meltdowns.”“Just STOP!” :Plan B:Behavior modification via staying calm to prevent “meltdowns.”“Just STOP!”


What’s Going On? :What’s Going On? First scenario: Mother: “John, can you please go do two hours of homework?” John: “Stop! Go away!” Second scenario: Mother: “John, can I make you fresh pancakes for breakfast?” John: “Stop! Go away!”


Just STOP! :Just STOP! ADHD is deficiency of frontal lobe brakes. First step is to STOP. It works! Even 5-10 minutes. Once under control: Correct choice is obvious to child. Correct parenting is obvious to parent.


The Overwhelmed Speedometer :The Overwhelmed Speedometer Imagine a stress speedometer At 60 mph, back wheels spin out and crash is inevitable. Inherit child at 40mph. “Calming” brings to 30mph ? keep at it. “Calming” brings to 50mph ? stop before spinout.


After stopping, next: :After stopping, next: Defuse, don’t inflame: Lower your voice. Stay calm. State rule once. Leave. Ignore the ravings of an out-of-control blob of neurons.


After stopping: :After stopping: Discussion will resume later when it can be useful. You are not giving in. Once calm: negotiate, negotiate, negotiate.


One more time: :One more time: Your ADHD child is much more likely over-whelmed than evil. Evil behaviors need to be squelched. Over-whelmed behaviors need to be calmly defused.


Pop Quiz :Pop Quiz A 13-year-old son with ADHD discovers that his bite-plate is missing from its handy container.  He angrily accuses everyone else of having taken it.  His mother explains the blatantly obvious fact that no one else would be interested in his used dental appliance.  He continues screaming and blaming her for its absence.


Question 1 :Question 1 This child is demonstrating good executive function. a)    True b)      False


Question 2 :Question 2 The accusatory behavior of this otherwise bright child can best be explained by: a)   He’s not quite smart enough to comprehend that his bite-plate isn’t worth stealing. b) He’s overwhelmed by frustration.


Question 3 :Question 3 Yelling back and accusing your child of behaving horribly would: a)    Prompt him to say, “Oh, thanks for helping me see the error of my ways.” b) Cause him to be even further overwhelmed.


Question 4 :Question 4 An initial attempt at helping him solve the problem is unsuccessful.  A useful parental response at this point would be: a) Keep escalating the screaming match. b) Stop, walk away, retain your composure, and resist the urge to get in the last word. Resume discussion when everyone is calm.


Question 5 :Question 5 This type of outrageous behavior in your ADHD child: a) Is a common part of the brakeless behaviors we summarize with the letters ADHD. b) Is the result of a nasty and selfish child.


Classic ADHD:Just a part of the Syndrome Mix :Classic ADHD:Just a part of the Syndrome Mix Classically defined ADHD Other Executive Dysfunctions Co-Occurring Problems Family Problems Okay, he has ADHD, but why does he…?


And let’s not forget the positive. ADHD people… :And let’s not forget the positive. ADHD people… Have an envious “Why not?” attitude. Live in the present. Often have extreme passion. Can be very creative. Can be lots of fun.


Conclusion :Conclusion This is the 50 year plan. Have some fun. The winner is the family that stays together.
