1

Mild MR

IQ is 50-55 thru approx. 70; 85% of all MR cases; may not become apparent until child is school age and has difficulty meeting educational demands

2

Moderate MR

Approx 10% or MR population; IQ between 35-40 and 50-55; usually develop communication skills during early childhood; can be trained to performed unskilled work under close supervision

3

Severe MR

3-4% of the MR population; IQ between 20-25 and 35-40; communicative speech usually does not develop during early childhood, although it may be acquired during the school-age years; can learn basic self-care, but need more supervision

4

Profound MR

Approx 1-2% of MR population; IQ of less than 20-25; communication skills and sensorimotor functioning are significantly impaired; need nearly constant supervision and generally benefit from a one-to-one relationship with a caregiver

5

Assessing MR

WISC has high floor, or minimum score of about 50; this test cannot provide accurate assessment of the level of MR. Stanford-Binet best to assess MR because its floor is much lower (also to assess giftedness).

6

Causes of MR

Varied and etiology may be undetermined in approximately 30-40% of cases. Clear etiologies easier to ascertain w/severe or profound MR. Most common identifiable cause is abnormalities in embryonic development; maternal illness; maternal consumption of alcohol, maternal use of nicotine or drugs and chromosomal changes.

7

What is the most common form of LD?

Reading disorder (dyslexia). 80% of LDs and approx. 4% of all children.

8

What percentage of those with LD do not complete High School?

40%

9

What percentage of children with LD have comorbid ADHD?

20-30%

10

What are most cases of reading disorder due to?

Poor sound awareness and sound-symbol correspondence (phonological processing).

11

What are the two types of dyslexia?

Surface dyslexia (AKA orthogonal dyslexia: difficulty with irregular words, ex. might = mit) and deep dyslexia (probs with many words, even "regular" ones)

12

Alexia

Dyslexia due to brain damage

13

What percentage of LD people struggle with significant psychosocial probs as adults?

Approx 33%

14

Borderline Intellectual Functioning

IQ between 71 and 84

15

Stuttering

Onset nearly always under 10; approx 3:1 boy:girl ratio; peak onset age 5. Often resolved by age 16, but may persist to adulthood, especially with males. Must cause impairment for a diagnosis. Rarely recommended, but Verpamil may help.

16

Phonological Disorder

A childhood communication disorder characterized by failure to use developmentally appropriate speech sounds; when speaking, individuals with this disorder may substitute one sound for another, omit sounds, incorrectly order sounds within words of syllables, lisp, or otherwise misarticulate sounds.

17

Autism and Gender

Boys more likely to have AD, but when girls have it they are more likely to also have MR

18

What percentage of individuals with autism show MR? Have seizures?

MR - about 70%. 25% develop seizures.

19

What indicates good prognosis with autism?

Normal range IQ (over 70) and spoken language by age 6.

20

Rhett's Disorder

A PDD in which a child demonstrates deceleration in head growth, replacement of purposeful hand skills w/stereotyped hand movements (hand-wringing), severe psychomotor agitation, severe impairment in language development,a nd loss of social engagement. Sx appear between 5 and 48 mths in age, after an apparently normal prenatal and perinatal development. Only occurs in females.

21

ADHD and nuerology

Frontal lobe functioning and frontal striata pathways are implicated in symptoms

22

Prevalence of ADHD

5-8% of children and adolescents (slightly lower in adults); sex ratio is 3:1 male:female. Comorbidity with ODD/CD, anxiety disorders, mood disorders, LD; strongly heritable (around 80%)

23

ODD

A disruptive behavior disorder characterized by negativistic, hostile, and defiant behavior (actively disobeying directions or parents or other caregivers, short temper, spitefulness, irritability, failure to take responsibility for one's mistakes or misbehavior, frequent arguments w/adults) lasting at least 6 mths.

24

Conduct Disorder

Disruptive Behavior Disorder characterized by aggression toward people or animals, destruction of property, deceitfulness, theft, and serious rule violations, childhood precursor to Antisocial Personality Disorder.

25

Pica

Some normality between 18-24 mths. Regular ingetsion of non-nutritive substances, often linked to MR or PDD, can lead to serious medical complications (lead poisoning for example)

26

Rumination Disorder

25% of these children may die as a result of malnutrition. Repeated regurgitation and often re-chewing of food without apparent distress; may result in malnutrition or death; linked to stress in parent-child relationship, along with lack of stimulation, child neglect.

27

Feeding disorder of infancy or early childhood ("failure to thrive").

Causes more probs when occurring before age 2. Failure to eat adequately for at least one month. Linked w/developmental delays, sometimes child abuse or neglect, extreme stress in the family, clear failures in parental "reading" of infant/child hunger cues, or forcing food.

28

Reactive Attachment Disorder

Child displays significantly disturbed social relatedness, linked directly to grossly pathological care (and not MR or PDD). Onset before age 5.

29

Two types of RAD

Inhibited Type: Children do not engage in many interactions, are hypervigilant, wary of letting other people come close to or make eye contact with them ("frozen watchfulness"), and often resistant toward physical affection. and Disinhibited Type: Children are indiscriminately sociable and fail to make selective attachments, act overly familiar (i.e. overly affectionate) with strangers.

30

Transient Tic Disorder

1+ motor or vocal tics daily for between 4 weeks and 12 months
