1- Pediatric Psych: ADHD Flashcards
Females with ADHD present more often with what type of sxs?
Inattentive sxs
What is the etiology of ADHD?
Multifactorial (may include genetic factors and environmental factors)
(genetic: ↑ rate in first-degree relatives of affected individuals
environmental: low birth weight, smoking)
How is attention deficit hyperactivity disorder (ADHD) defined?
Persistent inattention, hyperactivity, and impulsivity
inconsistent with the patient’s developmental stage
The diagnostic criteria of ADHD are a persistent pattern of inattention and/ or hyperactivity-impulsivity that interferes with functioning/ development as characterised by what?
6+ sxs for 6+ mos and inconsistent with developmental level and negatively impacts social/ academic/ occupational activities
What are sxs of inattention that contribute to a dx of ADHD? (must have 6+ for 6+ mos) (9)
- careless mistakes
- forgetful in daily activities
- difficulty sustaining attn
- easily distracted by extraneous stimuli
- avoid tasks that require sustained mental effort
- does not follow through/ finish work
- does not listen when spoken to directly
- difficulty w/ organization
- loses necessary items
What are sxs of hyperactivity-impulsivity that contribute to a dx of ADHD? (must have 6+ for 6+ mos) (9)
- fidgets
- leaves sit when inappropriate
- runs/ climbs excessively when inappropriate
- difficulty playing/ engaging in leisurely activities quietly
- “on the go”
- talks excessively
- blurts out answers prematurely
- difficulty awating turn
- interrupts/ intrudes others
In addition to characteristic sxs of inattention/ hyperactivity-impulsivity, what are the other diagnostic criteria for ADHD?
Sxs present prior to age 12, sxs present in 2+ settings, clear evidence sxs interfere w/ reduce quality of social/ academic/ occupational functioning
How are the types of ADHD specified?
Predominantly inattentive, predominantly hyperactive-impulsive, combined
How do you specify whether a pt is in partial remission with ADHD?
< 6 sxs for 6+ mos, after previous full dx
How do you specify ADHD severity?
Mild, moderate, severe
In what populations is ADHD difficult to dx and why?
Younger children (<5) due to age-appropriate behaviors in active children
In what age group is ADHD most common?
Elementary school-aged children (obtain info from teachers)
In adults, if ADHD is comorbid with SUD, mood disorder, or anti-social personality, the individual is at increased risk for what?
Suicide
Why must one use caution in new diagnoses of ADHD in adults?
Pt childhood recall of ADHD unreliable (obtain school records)
What are some conditions that can co-occur (or be ddx) with ADHD?
Learning disorders, oppositional defiance disorder, conduct disorder, substance abuse
ADHD manifesting as a result of something such as a stressful home, inappropriate schools, or under-stimulation are what?
Environmental factors
What must you be aware of when evaluating DDX of ADHD (in addition to co-occuring conditions and environmental factors)?
Medical conditions (that may manifest with sxs of ADHD)
ex. hearing/ visual impairments, sleep disorders, seizures
What is the purpose of a comprehensive medical, developmental education, and psychosocial eval for ADHD?
Confirm sxs, demonstrate functional complications, exclude ddxs, identify co-morbid conditions
Although there are several rating scales that may contribute to a dx of ADHD, they all still require what?
Validation with DSM5
What is the preferred rating scale for peds with ADHD?
Vanderbilt assessment scales
What is the preferred rating scale for adults with ADHD?
ASRS (ADHD self report scale)
What should you ask a parent when evaluating for ADHD?
- Performance in school
- Teacher acknowledgement of learning problems
- Happiness in school
- Behavioral problems
- Issues with completing assignments
What should you ask a teacher when evaluating for ADHD?
- Behavior
- Interventions required
- Learning patterns
- Functional impairment
- Child interactions with other students
- Work/ grades acceptable
What is the pathophysiology of ADHD?
Environmental factors, NT alterations, neuroanatomical changes in circuits
What does the RAS produce (ascending NT system)?
NE, serotonin, DA, ACh
What are the targets for the NTs produced by RAS?
Discrete nuclei within basal forebrain, limbic system, cerebral cortex
With respect to NTs, what contributes to the overall psych/ behavior function of an individual?
Brain region + concentration of NT inputs + concentration of relative density of receptors = overall psych/ behavioral function
What type of modulation can occur pre- or post-synaptically at the target nuclei or production sites (therefore having different effects)?
Pharmacologic
Increased NE leads to what?
Increased alertness/ arousal
Where is NE produced?
Locus Coeruleus (LC)
Where does NE target?
Throughout forebrain
What disorders are a/w NE imbalance?
Attention deficit disorders, mood disorders, anxiety disorders, drugs of abuse (psychostimulants)
How many receptor classes does NE have?
Two (and multiple subclasses)
NE acting on the cortex/ hypothalamus/ brainstem influences what?
Arousal and sleep/wake cycles, consciousness
