Pediatric Psych Flashcards
Pathogenesis of ADHD
- A genetic imbalance of catecholamine metabolism in the cerebral cortex appears to play a primary role
Various environmental factors may play a secondary role
controversial
Cerebral structural and functional abnormalities in what regions for ADHD? 2
These abnormalities result in what?

Dietary influences on ADHD
Areas of investigation include:
5

To meet criteria for ADHD symptoms must :
6

- Not be caused by other mental disorders
Two categories of core symptoms
2
- Hyperactivity/impulsivity
- Inattention
Each of the core symptoms of ADHD has its own pattern and course of development.
Symptoms of hyperactivity may include:
5
- Excessive fidgetiness (eg, tapping the hands or feet, squirming in seat)
- Difficulty remaining seated when sitting is required (eg, at school, work, etc)
- Feelings of restlessness (in adolescents) or inappropriate running around or climbing in younger children
- Difficulty playing quietly
- Difficult to keep up with, seeming to always be “on the go”
Symptoms of impulsivity include:
4
- Excessive talking
- Difficulty waiting turns
- Blurting out answers too quickly
- Interruption or intrusion of others
Hyperactive and impulsive symptoms
1. Hyperactive symptoms are typically observed by the time the child reaches what age?
- Increase during the next three to four years, peaking in severity when the child is ____ years old
- At what age do the hyperactive symptoms begin to decline?
- Impulsive symptoms usually persist for how long?
- 4 years old
- 7-8
- over 8
by the adolescent years symptoms may not be noticeable to others although may feel restless or unable to settle down - throughout life
Symptoms of inattention
9
- Failure to provide close attention to detail, careless mistakes
- Difficulty maintaining attention in play, school, or home activities
- Seems not to listen, even when directly addressed
- Fails to follow through (eg, homework, chores, etc)
- Difficulty organizing tasks, activities, and belongings
- Avoids tasks that require consistent mental effort
- Loses objects required for tasks or activities (eg, school books, sports equipment, etc)
- Easily distracted by irrelevant stimuli
- Forgetfulness in routine activities (eg, homework, chores, etc)
Inattentive subtype:
1. Children with the inattentive subtype often are described as?
- Typical presenting complaints center on what kind of problems?
- Symptoms of inattention typically are not apparent until the child is what age and last how long?
- having a sluggish cognitive tempo and frequently appear to be daydreaming or “off task“.
- cognitive and/or academic problems.
- 8-9 years of age and usually are a lifelong problem
Symptoms may impair function in 3 areas
- Academic
- Social
- -Social skills in children with ADHD often are significantly impaired - Occupational
Evaluation
4
- Medical
- Developmental
- Educational
- Psychosocial evaluation
Medical evaluation : Interview of the parents
- How is your child doing at school?
- Have you or the teacher noticed any problems with learning?
- Is your child happy in school?
- Does your child have any behavioral problems at school or home, or when playing with friends?
- Does your child have problems completing school assignments at school or home?
Medical evaluation: History
7
- Prenatal exposures (eg, tobacco, drugs, alcohol)
- Perinatal complications or infections
- Central nervous system infection
- Head trauma
- Recurrent otitis media
- Medications
- Family history of similar behaviors is important because ADHD has a strong genetic component
PE
4
- Measurement of height, weight, head circumference, and vital signs
- Assessment of dysmorphic features and neurocutaneous abnormalities
- A complete neurologic examination, including assessment of vision and hearing
- Observation of the child’s behavior in the office setting
Developmental and behavioral assessment includes
6
- Specific information about the onset, course, and functional impact of ADHD symptoms
- Emotional, medical, and developmental events that may provide an alternative explanation for the symptoms
- Developmental milestones, particularly language milestones
- School absences
- Psychosocial stressors
- Observation of parent-child interactions
Behavior rating scales
What are the two types?
- ADHD specific scales (narrow band scales)
2. Broadband scales assess a variety of symptoms
ADHD specific scales (narrow band scales) are used for what?
Can be used to establish the presence of the core symptoms of ADHD.
Broadband scales assess a variety of symptoms
2 categories
- Internalizing behaviors (eg, feeling depressed, anxious, withdrawn)
- Externalizing behaviors other than ADHD (eg, aggression).
Broadband scales (with the exception of the Conners’ Long form) are not recommended for what?
What should they be used for?
to establish the presence of the core symptoms of ADHD
less sensitive and specific (
Educational evaluation
4
- Child’s teacher to complete an ADHD-specific rating scale
- A narrative summary of classroom behavior and interventions, learning patterns, and functional impairment
- Copies of report cards and samples of schoolwork
- Review of school-based multidisciplinary evaluations (if such evaluations have been performed)
Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5) criteria: the DSM-5 diagnosis of ADHD requires what? 3
- ≥6 symptoms of hyperactivity and impulsivity
- or ≥6 symptoms of inattention
