Autism/ADHD Flashcards
Characterized by a persistent pattern of diminished sustained attention and high levels of impulsivity or hyperactivity
Attention-Deficit/Hyperactivity Disorder (ADHD)
at what age does ADHD must be present by?
12
3 major specifiers for ADHD
- ADHD, Predominantly Hyperactive/Impulsive (ADHD-PH)
- ADHD, Combined Type
- ADHD, Predominantly Inattentive (ADHD-PI)
which ADHD type is excessive fidgeting and restlessness, hyperactivity, difficulty remaining seated and waiting turns, impulsivity
ADHD, Predominantly Hyperactive/Impulsive (ADHD-PH)
which ADHD type is disorganization, forgetful, easily distracted, daydreamers, difficulty completing tasks
ADHD, Predominantly Inattentive (ADHD-PI) aka Attention Deficit Disorder (ADD)
what is the epidemiology of ADHD
- 2-18% of children; 3-5% of adults*
- males MC
- 4:1 for ADHD-PH, 2:1 for ADHD-PI* - Comorbidities - conduct disorders, anxiety, depression, learning disorders
biological causes of ADHD
- Impaired catecholamine (norepinephrine, dopamine) metabolism in the brain
- Genetics - increased risk in pts with (+) family history of ADHD, up to 92% for monozygotic twins
environmental causes of ADHD
- Intake of food additives or refined sugar
- Deficiency of fatty acids, iron or zinc
- Prenatal tobacco or alcohol exposure
- Screen time exposure
- Prematurity, low birth weight
criteria for ADHD
6+ symptoms from one category (inattentive or hyperactive), or 6+ from each, for 6+ months
1. Maladaptive and inconsistent with developmental level
2. Some symptoms must have been present before age 12
3. Clear functional impairment from symptoms present in 2+ settings
4. Symptoms not better accounted for by another disorder
5. symptoms
- inattentiveness
- Hyperactivity
- Impulsivity
what are the non-pharm tx for ADHD
- Behavioral Interventions
- Cognitive Therapy
(Psychotherapy) - Dietary Modifications
what is the preferred tx over medication for preschool ADHD pts
Behavioral Interventions
Reported to improve behavior in preschool-age pts
what tx is an adjunct for older children and teens and alone, does not improve core ADHD s/s in school-age pts
Behavioral Interventions
common interventions of behavioral interventions
- Daily schedule
- Using charts and checklists
- Minimal distractions
- Limiting choices
- Specific and logical storage places
- Rewarding positive behaviors
- Using calm discipline, such as time-out
common interventions of behavioral interventions
- Daily schedule
- Using charts and checklists
- Minimal distractions
- Limiting choices
- Specific and logical storage places
- Rewarding positive behaviors
- Using calm discipline, such as time-out
what is not recommended as monotherapy
cognitive therapy
No major improvement in core symptoms of ADHD
Any improvement noted is unlikely to transfer to practical settings (ex. school, home)
what are 3 dietary modifications that could help ADHD
- Elimination Diets
- not recommended - Fatty Acid Supplementation
- not recommended - Other Alternative Therapies
- Megavitamins, chelation, “detox”, herbal or mineral supplements
- No solid evidence to support efficacy
- Can have harmful side effects and setback in improvement
which dietary modifications must you closely monitor to ensure adequate nutrition for children when tx ADHD?
elimination diets
what are the pharm tx of ADHD
- Stimulants
- Methylphenidate
- Amphetamines - non-stimulants
- Atomoxetine (Strattera)
- Alpha-2 Adrenergic Agonists
- antidepressants
Ritalin
Methylphenidate
Focalin
Methylphenidate
Concerta
Methylphenidate
Quillivant
Methylphenidate
adderall
amphetamine
Lisdexamfetamine
amphetamine
(vyvanse)
Clonidine (Kapvay)
Alpha-2 Adrenergic Agonists
Guanfacine (Intuniv)
Alpha-2 Adrenergic Agonists
what is the criteria for pharm tx of ADHD
- Full diagnostic assessment has been completed and confirms dx
- Child is at least 6 years old¹
- School will cooperate in administration and monitoring of rx
- No concerns about substance use in household members
- No history of…
- Sensitivity or allergy to chosen medication
- Uncontrolled tachycardia
- Uncontrolled hypertension
- Uncontrolled anxiety
- Seizures
- Pervasive developmental delay
- Tourette syndrome
what is the 1st line tx for ADHD?
pharm
Generally considered first-line tx for children 6 yo and up with functional impairment due to ADHD
Stimulants
what schedule are Stimulants
schedule II
which pharm tx is known to increase intrasynaptic levels of catecholamines (norepinephrine, dopamine)
stimulants
which stimulant blocks reuptake of catecholamines
Methylphenidate
which stimulant blocks reuptake and stimulate dopamine release?
amphetamines
benefits of extended release forms of stimulants
helpful due to need to treat ADHD in multiple settings
1. Reduce adverse SE at peak levels of drug
2. Reduce “crash” SE when drug is cleared
Many stimulants come with special release formulations to manage symptoms and what else?
reduce tachyphylaxis
Partial immediate-onset, partial delayed-onset
Some have capsules that can be opened, some must be swallowed whole
what medications do not treat emotional problems, defiant behavior, learning impairment, reduced social skills
stimulants
may be able to miss doses on weekends, vacations
drug holiday
how do you adjust dosing schedules?
based on symptoms, activities and functional impairment
Start at lower doses and gradually titrate up until:
40-50% improvement in symptoms
SE become intolerable or max dose reached
common SE of stimulants
- Reduced appetite
- Insomnia or nightmares
- Feeling “on-edge” or “jittery”
- Emotional lability
- Weight loss and/or decreased height
- Routine monitoring of growth in pediatric pts - Development of tics
- Usually mild and correctable with dose adjustments
less common SE of stimulants
- CV - Increased HR, increased BP, palpitations; peripheral vasculopathy (Raynaud’s)
- Priapism - seen with methylphenidate; very rare
- Neuro - Headache, dizziness
- GI - N/V/D
- Psych - psychotic symptoms, manic symptoms
- Diversion or Misuse
pt is experiencing decreased appetite while on stimulants, how could you fix this?
dose at or following a meal; emphasize nutrient-dense foods
pt is experiencing poor growth while on stimulants, how could you address this?
drug holiday or change in therapy if substantial deceleration
pt is experiencing dizziness while on stimulants, what can you do?
monitor BP and HR; adequate fluids; XR formulations
pt is experiencing sleep disturbances, what could you do?
normal bedtime routine; earlier dosing or decrease/omit last dose of day
pt is experiencing mood lability while on stimulants, what could you do?
XR formulations; evaluation for comorbid psych disorders
