ADHD Flashcards
What are some sources of school failure?
- Health issues
- Emotional issues
- Learning issues
- Attention issues
*try to distinguish where coming from – cognitive ability specific to subject? auditory or visual? Emotional changes? Etc.
What are the risks to untreated adhd?
cascade of negative consequences: poor self esteem –> poor academic performance –> risk taking, substance abuse, etc. –> poor employment options, poor health outcomes, poor relationships
3 characteristics of adhd
- inattentiveness
- hyperactivity
- impulsivity
Definition / diagnostic criteria ADHD
- Interferes w/functioning across settings: home, school, work
- Behaviors > signifcant than peers
- Triad of behaviors beyond range of accepted for “normal”
- At least 6 months
- Symptoms before 12 years of age
3 subtypes of adhd
Neurobiology: structural differences associated w/adhd
Chronic neurobehavioral disorder
smaller frontal lobes
Neurobiology: functional differences associated w/adhd
- Lower blood flow
- Response to meds
- Alteration of neurochemical transmission
Chronic neurobehavioral disorder
ADHD: genetics vs environment
- Very high incidence in twin studies
- 75% variance in phenotype is genetic, not environmental
Specific genes associated with adhd
•Dopamine receptor gene
–Cognition, memory, exploratory behaviors
•Dopamine transport gene
–Site of action of stimulants
•Similar genes linked to other mental health issues
prenatal/parinatal factors associated with adhd
- Pregnancy complications
- Prematurity/SGA
- Hypoxemia
- Hypoperfusion: – low cerebral blood flow associated with increased dopamine receptor availability in adols with ADHD
- Maternal smoking
psychosocial factors associated with adhd
- Maternal depression
- parenting skills/stress
biologic factors associated with adhd
- Lead exposure: even low lead levels showed hyperactivity in preschoolers
- Iron deficiency
- Obstructive sleep apnea
diet factors associated with adhd
- food additives
- sugar
*may be triggers in genetically susceptible child - make better or worse

- Inappropriate
- Unaware of full range of behaviors
- School behavior
- Social interactions
What to look for in interview w/preschool teacher: adhd
- Normative perspective
- Structured and unstructured samples of behavior
Important concepts w/elementary/HS teacher interview: adhd
- May have no knowledge of outside classroom behavior
- poor interrater reliability among teachers
- Parent-teacher agreement =74%
Characteristics of students perspectives on adhd symptoms
- Under report symptoms
- Under rate level of impairment
Who should be involved in adolescent interviews for adhd and why?
- Adolescent alone
- Confidentiality
- Concerns
- Perception of school and family issues
- Sensitive topics
- Use of ETOH, drugs
- Driving habits
- Parents alone
- Perceptions of issues
- Contact with school
- Approaches tried
- Expectations from evaluation
- Adolescent and parents together
* Shared concerns?
Rating scales in adhd: why, disadvantes, types
- Attempt to objectify behavior
- Some normed to age and gender
- Impressionistic, subjective
- Some specific to ADHD, others to range of emotional/behavioral problems
Specific provider rating tools for adhd, recommended
- Vanderbilt (AAP)
- ADHD
- Comorbidities
- Connors
- McCarney (ADDES) short / long forms
