25
mental retardation/intellectual disability is coded on which axis?
axis II

29
What is a learning disorder?
academic achievement (in reading, math, written language) that is significantly lower than expected for chronological age, level of education, and level of intelligence (fyi - often due to ∆ cognitive processing)
30
what should you do before diagnosing learning disorders?
always rule out sensory deficients (hearing, vision, etc)
31
treatment for learning disorders?
remedial education
32
DSM criteria for oppositional defiant disorder (ODD), include duration
> 6 months of negativistic, hostile, and defiant behavior during which there is - a frequent loss of temper - arguments with adults - defying adult's rules - deliberately annoying people - easily annoyed - anger and resentment - spitefulness - blaming others for mistakes/misbehaviors

ADHD | learning disorders
36
treatment for conduct disorder (CD)
- multimodal treatment approach involving both family + community - consistent rules and consequences
37
3 diagnostic criteria of ADHD
impulsivity inattention hyperactivity
38
pathophysiological cause of ADHD?
decreased DA and NE tracts in the prefrontal cortex -> hyperactivity + impulsivity
39
DSM criteria for ADHD, include duration
≥ 6 sx of inattentiveness, hyperactivity, or both that - lasted for 6 mo - onset prior to age 7 - observed in ≥ 1 setting (home + school)
40
ADHD is highly comorbid with:

∆ btwn stimulants (methylphenidate, dextroamphetamine, amphetamine salts) and atomoxetine (non-stimulant) how quickly do they work? how does this affect sleep? who are these usually given to?
stimulants (methylphenidate, dextroamphetamine, amphetamine salts) - RAPID onset - ADR: insomnia atomoxetine - non-stimulant - GRADUAL onset (2-3 weeks) - ADR: sedation - given to people/families with substance abuse
42
What alternatives are there to stimulants (methylphenidate, dextroamphetamine, amphetamine salts) and atomoxetine (non-stimulant) for treatment of ADHD? When is it usually given?
clonodine, guanfacine (both alpha-2 agonist) usually given if patients cannot tolerate 1st line treatments, or as an adjunct therapy to stimulants (help with sleep disturbances/agitated behavior

51
How is autistic disorder different than asperger disorder?

same symptoms as Autistic disorder in terms of problems with SOCIAL INTERACTION (lack of reciprocity, lack of relationships, lack of interest in sharing enjoyment with others) & REPETITIVE STEREOTYPED BEHAVIOR (spinning wheels, toe walking, hand flapping), but children with Asperger disorder have NORMAL language and cognitive development
53

depression because the social difficulties often lead to chronic frustration and ultimately depression
54

PANDAS - get anti-streptolysin O (ASO) and anti-streptococcal DNAse B (anti-DNAse B) (can also cause OCD along with the tics)
