Q

list the 6 symptoms of criterion A for specific learning disorder (one of which must be present)

A
  1. inaccurate or slow and effortful WORD READING
    (i. e reads single works aloud incorrectly or slowly and hesitantly, frequently guesses words, has difficulty sounding out words)
  2. difficulty UNDERSTANDING the MEANING of what is read
    (i. e may read text accurately but not understand the sequence, relationships, inferences or deeper meanings of what is read)
  3. difficulties with SPELLING
    (i. e may add, omit, or substitute vowels or consonants)
  4. difficulties with WRITTEN EXPRESSION
    (i. e makes multiple grammatical or punctuation errors within sentences, employs poor paragraph organization, written expression of ideas lacks clarity)
  5. difficulties with mastering NUMBER SENSE, number facts or calculation
    (i. e has poor understanding of numbers, their magnitude, and relationships; counts on fingers to add single digit numbers instead of recalling math fact as peers do; gets lost in the midst of arithmetic computation and may switch procedures)
  6. difficulties with MATHEMATICAL REASONING
    (i. e has severe difficulty applying mathematical concepts, facts or procedures to solve quantitative problems)

Q

what is criterion B for specific learning disorder

A

the affected academic skills are substantially and quantifiably BELOW THOSE EXPECTED for the individuals chronological age, and cause SIGNIFICANT INTERFERENCE with academic or occupational performance or with activities of daily living, as confirmed by individually administered STANDARDIZED ACHIEVEMENT MEASURES and comprehensive clinical assessment

–for individuals 17 and older, a documented hx of impairing learning difficulties may be substituted for the standardized assessment

Q

how do you define what a specific learning disorder is–broadly speaking

A

it is a neurodevelopmental disorder with a BIOLOGICAL origin that is the basis for abnormalities at the COGNITIVE level that are associated with BEHAVIORAL signs of the disorder

–> persistent difficulties learning KEYSTONE ACADEMIC SKILLS

Q

define “persistence” in the context of children and adolescence

A

persistence = restricted progress in learning (i.e no evidence that the individual is catching up with classmates) for at least SIX MONTHS despite provision of extra hep at home or school

i.e difficulties learning to read single words that do not fully or rapidly remit with the provision of instruction in phonological skills or word identification strategies

23
Q

what is one robust clinical indicator of specific learning disorder

A

low academic achievement for age (or average achievement sustained only in the context of extraordinarily high levels of effort or support)

24
Q

what is a clinical indicator of specific learning disorder in adults

A

avoidance of activities that require that academic skill

25
Q

is there a clear natural cut off point that can be used to differentiate those with specific learning disorder from those without?

A

no

academic skills are distributed along a continuum, and theres no natural cut off point

any threshold used to specify low academic achievement is to a large extent arbitrary

26
Q

what type of measure should you use to assess academic achievement, especially if assessing adults

A

a psychometrically sound and culturally appropriate test of academic achievement that is norm-referenced and criterion-referenced

27
Q

what general cut off can be used to mark someone has having low academic achievement

A

low scores on one or more standardized tests or subtests within an academic domain–> at least 1.5 standard deviations below population mean for age/below the 7th percentile

28
Q

why are these types of disorders called “specific” learning disorders

A

four reasons

  1. they are not attributable to intellectual disabilities –> affect learning in people with otherwise normal levels of intellectual functioning
    (“unexpected academic underachievement”)
  2. cannot be attributed to more general external factors like economic or environmental disadvantage, chronic absenteeism, lack of education
  3. cannot be attributed to neurological or motor disorders or to hearing or vision disorders
  4. it may be restricted to one academic domain
29
Q

what is normal IQ

A

70 (+/- 5)

30
Q

can someone who is “gifted” have specific learning disorder

A

yes

31
Q

can specific learning disorder be diagnosed before formal learning starts

A

no

32
Q

what signs or symptoms frequently preceed diagnosis of specific learning disorder

A

delays in attention, language or motor skills in preschool years that may persist and co-occur with specific learning disorder

uneven profile of abilities is common (i.e above average in drawing/visuospatial skills, with slow, effortful reading)

33
Q

which specific learning disorder is known to be associated with cognitive deficits

A

difficulty learning to read words

34
Q

is assessment of cognitive processing deficits required for diagnosis

A

no

while many people with specific learning disorder do show poor performance on psychological tests of cognitive processing, they are often not specific, and no not invariably occur. also, they may also be present in other disorders like adhd

35
Q

is specific learning disorder associated with increased risk of suicidal ideation and suicide attempts in children and adults?

A

yes

36
Q

are there any known biological markers for specific learning disorder

A

no

–> while as a group, people with specific learning disorder show circumscribed alterations in cognitive processing and brain structure and function, and also there are genetic differences at the group level, cognitive testing, neuroimaging and genetic testing are not useful for diagnosis at this time

37
Q

what is the prevalence of specific learning disorder across academic domains of reading, writing and mathematics?

A

5-15% among school age children across different languages and cultures

38
Q

what is the prevalence of specific learning disorder in adults

A

unknown but appears to be around 4%

39
Q

what behavioural manifestations might hint at a specific learning disorder

A

oppositional behaviour

reluctance to engage in learning

40
Q

is specific learning disorder lifelong?

A

yes–> but course and clinical expression are variable

41
Q

what affects the course and clinical expression of specific learning disorder

A

depends on the interactions among the task demands of the environment, range and severity of the learning difficulties, the individuals learning abilities, comorbidity and available support systems and interventions

42
Q

how are manifestations of specific learning disorder affected by age

A

manifestations of specific learning disorder can change over time, so someone might have a persistent or shifting array of learning difficulties across the lifespan

43
Q

what comorbidities are common across the lifespan in those with specific learning disorder

A

episodes of severe anxiety or anxiety disorders

this includes somatic complaints or panic attacks

can accompany both the circumscribed and broader expression of learning difficulties

44
Q

what environmental factors increase risk for specific learning disorder

A

prematurity or very low birth weight

prenatal exposure to nicotine

45
Q

are specific learning disorders heritable? what is the increase risk?

A

specific learning disorders appear to aggregate in families

relative risk of specific learning disorder in reading (4-8x) or math (5-10x) is substantially higher in first degree relatives of those with specific learning disorder than those without

46
Q

what is the heritability of reading ability/disability

A

high heritability for both, in both alphabetic and nonalphabetic languages –> heritability estimates values greater than 0.6

covariation between different learning disabilities is high–> genes related to one presentation are highly correlated with genes related to another manifestation

47
Q

what comorbid condition predicts worse mental health outcomes with specific learning disorder

A

comorbidity with ADHD is predictive or worse MH outcomes

48
Q

is specific learning disorder more common in males or females

A

males (2:1 to 3:1)

49
Q

list some of the functional impacts of specific learning disorder

A

–lower academic achievement

–higher rates of high school dropout

–lower rates of post secondary education

–high levels of psychological distress and poorer overall mental health

–higher rates of unemployment and under employment

–lower incomes

50
Q

what is the differential dx of specific learning disorder (list)

A
  1. normal variations in academic achievement
  2. intellectual disability (intellectual development disorder)
  3. learning difficulties due to neurological or sensory disorders
  4. neurocognitive disorders
  5. ADHD
  6. psychotic disorders
51
Q

how do you distinguish between normal variations in academic achievement and specific learning disorder

A

external factors i.e access to adequate teaching –> because difficulties persist in presence of adequate educational opportunity and exposure to same instruction as peer group and competency in language of instruction

52
Q

how do you distinguish between intellectual disability and specific learning disorder

A

ID–> IQ below 70

specific learning disorder–> difficulties occur in context of IQ above 70

*if ID is present, specific learning disorder can only be diagnosed separately if the specific learning disorder is in excess of those usually associated with ID

53
Q

how do you distinguish between specific learning disorder and a neurocognitive disorder

A

neurocognitive disorder–> marked decline from a former state (not the case with specific learning disorder)

54
Q

how do you distinguish ADHD and specific learning disorder

A

ADHD–> not so much a difficulty with learning the skill, but instead with performing it

*however, ADHD and specific learning disorder occur together more frequently than would be predicted by chance, and if both criteria are met, both dx can be given

55
Q

how do you distinguish between specific learning disorder and the academic and cognitive-processing difficulties associated with psychotic disorders/schizophrenia

A

in psychotic disorders, there is a DECLINE (often rapid) in these functional domains unlike in specific learning disorder

56
Q

what common comorbidities occur with specific learning disorder

A

neurodevelopmental–> ADHD, communication disorders, developmental coordination disorder, ASD

other–> anxiety, depression, bipolar
