Chapter 12 –Disorders of Childhood and Adolescence

 

I.  Classification

        A.  DSM categories

                1.  Kids can be diagnosed with almost all adult disorders (e.g., anxiety, depression)

                2.  There are also disorders diagnosed only in kids, primarily in kids, or which one must exhibit as a child initially (our focus)

        B.  Often grouped into Internalizing vs. Externalizing (Disruptive Behavior) problems, and Developmental problems

 

II.  Attention-Deficit/Hyperactivity Disorder (ADHD)

        A.  Symptoms of inattention

                ex:  easily distracted, difficulty organizing or sustaining attn

        B.  Symptoms of hyperactivity/impulsivity

                ex:  fidgety, restless, interrupts, can’t sit still, blurts out answers

        C.  For ADHD, can have primarily A, primarily B, or both.

        D.  Etiology:  mixed evidence for a variety of causes; clearly a genetic component, other biol/environ factors as well

        E.  Treatment and Treatment Issues

                1.  Ritalin (methylphenidate) and other meds

                        a.  generally pretty effective in reducing symptoms

                        b.  somewhat less effective in reducing things like academic difficulties

                        c.  issues re medication

                                i.  good-behavior drug” or facilitator for child’s own behavior?

                                ii. implications of medicating kids?  What message does that send in general?

                                iii.  potential for abuse?

                                iv.  may affect physical growth

                2.  Behavioral Approaches

                        a.  differential reinforcement/other operant methods (e.g., “daily report card” at school)

                        b.  gradual increase in goals

                        c.  parent-training, social skills training

                3.  Evaluation of treatments

a.  Meds alone, BT alone, and combo all effective in reducing symptoms

b.  Combo of meds and beh tx seems best, although not in every analysis

                4.  Is ADHD overdiagnosed?

                        a.  are rigid settings the problem or the kid’s behavior?

                        b.  are there other reasons for kid’s behavior?

                        c.  cormorbidity with conduct disorder

 

III.  Conduct Disorder

        A.  Symptoms can be clustered:

                1.  aggression to people and/or animals

                2.  destruction of property

                3.  deceitfulness or theft

                4.  serious violation of rules

        B.  Etiology

                1.  Biological factors:  some evidence for genetic component, possible neuropsych deficits

                2.  Parenting/Family Life:

                        a.  inconsistent/harsh parenting

                        b.  modeling of abusive behavior

                        c.  lack of moral sense in family environment

                        d.  failure to reason/explain with children

                3.  Impact of Deviant Peer Groups

                4.  Cognitive Perspective

        C.  Treatment

                1.  Family Interventions/Parent Training

                2.  Multisystemic Therapy (MST)

                3.  Behavioral contracting

                4. Anger-management, problem-solving, cognitive challenging, moral skills training

 

IV.  Oppositional Defiant Disorder

        A.  Less severe form of Conduct Disorder?

        B.  Sxs include arguing; annoying behavior; angry, hostile, resentful, negative attitude, resentment:  brattiness

        C.  ONLY diagnosed if criteria for CD not met

 

V.  Mental Retardation

        A.  Coded on Axis II, and MUST be present prior to age 18

        B.  Must have both:

                1.  Significantly subaverage IQ (or IQ equivalent)

                2.  Significant limitations in adaptive functioning

                        ex:  in communication, self-care, social skills, etc

        C.  Level of MR determined primarily by IQ score:

                1.  mild MR:  50-55 à abt 70 (abt 85%)

                2.  moderate MR:  35-40 à 50-55 (abt 10%)

                3.  severe MR:  20-25 à 35-40 (abt 3-4%)

                4.  profound MR:   <20-25 (abt 1-2%)

                5.  severity unspecified” – when can’t test IQ

        D.  AAMR approach

                1.  focus not on severity of disability

                2.  focus IS on what remediation/support is needed to increase adaptive functioning

        E.  Etiology

                1.  Known for sure in abt 25% of cases

                        ex:  Down Syndrome, PKU, lead poisoning

                2.  Most cases have no known etiology

        F.  Prevention and Treatment Issues

                1.  when possible, address known cause

                2.  behavioral approaches (eg, ABA for inappropriate/harmful behaviors, pos reinf for skills training, shaping, chaining)

                3.  alternative communication systems

                4.  assisted living/working programs

                5.  Issue:  mainstreaming, “least restrictive environment”

 

 

V.  Learning Disorders

        A.  Disorders of Reading, Mathematics, and Written Expression

        B.  Diagnosed based on a SIGNIFICANT discrepancy between expectation (based on age/IQ) and specific achievement

                1.  BUT, DSM dx and state requirements for accommodations not always the same

                2.  Recent move from failure-based model:  “response to intervention” model - child’s response to intervention is < expected

        C.  Etiology

                1.  genetic component, organic deficits/abnormalities

                2.  CAN be due in part to perceptual deficits, but must be > deficits alone should lead to

                3.  language processing and other such deficits (e.g., difficulty recognizing phonemes)

        D.  Prevention and Treatment Issues

                1.  Individualized instruction, specific educational programs

                2.  Environmental and/or task modifications (accommodations)

                3.  Issue:  Are LDs really “mental disorders”?

                4.  Issue:  Are LD diagnoses sought out or assigned inappropriately?

 

VI.  Autistic Disorder (Autism)

        A.  Most well-known of the Pervasive Developmental Disorders

                1.  Asperger’s also increasingly well known, but of questionable utility?

        B.  Symptoms include:

                1.  impairment in social interaction

                2.  impairment in communication

                3.  repetitive/stereotyped patterns of behavior, interests, activities

        C.  Must be evident before age 3

        D.  Usually, but not always, accompanied by MR

                à how are MR and autism different?

                1.  some with autism DON’T have MR (ex:  Temple Grandin, see pg 414)

                2.  may have area of remarkable ability (“idiot savant” or “autistic savant”)

                3.  patterns on IQ tests more varied

        E.  Etiology

                1.  Older theory:  psychogenic à “refrigerator moms”

                2.  Current:  biologically determined, with neurological differences

                3.  Lots of other theories embraced by parents, but with lots of evidence countering them and none to support them

        F.  Treatment and Treatment Issues

                1.  Behavioral Approaches

                        a.  basic behavioral approaches (eg, pos reinf), intensive beh tx (applied beh analysis – Lovaas)

                        b.  aversive tx

                2.  facilitated communication”

                3.  medication (antipsychotics, stimulants)

 

VIII.  Tourette’s Syndrome

        A.  Must have both motor AND vocal tics

        B.  Diagnosed with Tic Disorder, not Tourette’s, if only one

        C.  Swearing?

 

IX.      Separation Anxiety Disorder
