Description : Check out this medical PowerPoint presentation titled "Learning Disorders…or Disabilities…or Differences" by Jess P. Shatkin, MD, MPH.
This medical PowerPoint presentation talks learning disorders, also known as learning disabilities.
learning disabilities, are neurodevelopmental disorders that affect an individuals ability to acquire, process, and use information effectively. These disorders can manifest in various areas, including reading, writing, math, attention, and social skills.
The exact causes of learning disorders are not well understood, but they are believed to be related to differences in brain development, genetics, and environmental factors. These disorders are typically diagnosed during childhood or adolescence, and they can persist throughout an individuals lifetime.
Common types of learning disorders include Dyslexia, Dyscalculia, Dysgraphia, Attention Deficit Hyperactivity Disorder, ADHD, and Autism Spectrum Disorder (ASD).

Slide 1-

Learning Disorders…or Disabilities…or Differences Jess P. Shatkin, MD, MPH Vice Chair for Education NYU Child Study Center New York University School of Medicine
Slide 2-

Learning Objectives Residents will be able to: Provide a legal definition of learning disorders. Describe how IQ and achievement tests are used in determining the presence of learning disorders, and draw the IQ bell curve. Identify the 3 primary learning disorders. Choose which neuropsychiatric tests are most appropriate for assessing educational level, visual/motor integration, adaptive skills level, memory, executive function, and thought content. Describe the differences between the 2 public laws which provide educational support for learning disordered children.
Slide 3-

Neuron Cell Migration The human brain develops through cell division and then cell migration Cell migration occurs when neurons develop and then travel through the brain to pre-programmed areas In most cases, cell migration proceeds in expected ways Sometimes, cell migration proceeds in an “abnormal” or atypical way

Diagnostic Features Diagnosed when an individual’s achievement on individually administered, standardized tests in reading, math, or written expression is substantially below that expected for age, schooling, and level of intelligence “substantially below” is usually defined as a discrepancy of more than two standard deviations (one standard deviation = 15 points) between achievement and IQ (or roughly 20+ points)
Slide 9-

The IQ Bell Curve (1) IQ is plotted on a bell-shaped curve 100 is the defined “average” for both IQ and achievement tests at a given age level The usual (but not invariable) standard deviation is 15 points
Slide 10-

The IQ Bell Curve (2) Roughly 70% of individuals fall between 85 – 115 130 & above = Gifted (2%) 120 – 129 = Superior (7%) 110 – 119 = High Average (16%) 90 – 109 = Average (50%) 80 – 89 = Low Average (16%) 71 –79 (84 per DSM) = Borderline (7%) 70 & below = Mental Retardation (2%)

Associated Features Demoralization, low self-esteem, and deficits in social skills are common Children with LDs are not as socially competent as peers and have more difficulty understanding affective states in complex/ambiguous situations School drop-out rate for children with LDs is nearly 40% Great overlap between Axis I disorders and LD: 10 – 25% cross over with: CD, ODD, ADHD, MDD, Dysthymia
Slide 14-

Prevalence Range from 2 – 10% Estimated to include 5% of American children Approximately 50% of children receiving special services at school are LD
Slide 15-

Reading Disorder…aka Dyslexia Oral reading is characterized by distortions, substitutions, or omissions; both oral and silent reading are slow with comprehension errors Rare to find Math D/O and/or Written Expression D/O in the absence of Reading D/O 60 – 80% are males Prevalence estimated at 4% of school-aged children Aggregates in families (35 – 40% have a 1st degree relative also effected)
Slide 16-

What does Dyslexia mean? Dyslexia is an unexpected difficulty with reading in children who otherwise have the intelligence to learn to read Dyslexia is not “outgrown” Word retrieval and identification is slowed Affects spoken and written language
Slide 17-

Dyslexia versus IQ In typical readers, IQ and reading not only track together, but also influence each other over time. In children with dyslexia, IQ and reading are not linked over time and do not influence one another. Data from the Connecticut Longitudinal Study (12 year study of 445 kids given regular reading and IQ tests) Shaywitz et al, 2010
Slide 18-

Reading Disorder (2) Thought to be a left hemisphere defect; planum temporale has been found to be lacking in expected symmetry; more disorganized and smaller cell bodies in the visual magnocellular system Persist into adolescence and adulthood Initial severity of reading disorder is the best predictor of adult reading levels (prior to Shaywitz study, last slide, intelligence was also thought to be a predictor here)
Slide 19-

Mathematics Disorder Prevalence roughly 1% of school children Usually apparent by 2nd or 3rd grade Many skills may be affected: Linguistic skills (e.g., understanding terms, operations, concepts, decoding, etc.) Perceptual skills (e.g., recognizing or reading numerical symbols, mathematical signs, clustering objects into groups, etc.) Attention skills (e.g., copying numbers or figures correctly, remembering to “carry” numbers, observing operational signs, etc.) Mathematical skills (e.g., following steps, counting objects, multiplication tables, etc.)
Slide 20-

Mathematics Disorder (2) Associated with a pattern of deficits in neurocognitive & adaptive functions generally attributed to R hemisphere, including spatial recognition, visuoperceptual/simultaneous info processing and social emotional functioning; often referred to as Nonverbal Learning Disorder (NVLD) NVLD generally persists into adulthood and may worsen over time; increased risk for internalizing d/o (anxiety and depression) and socio-emotional difficulties The abnormal language characteristics (e.g., poor prosody and pragmatics but good vocabulary) and pronounced social difficulties lead to questions about a connection with PDD (esp Asperger’s) and Schizoid PD
Slide 21-

Disorders of Written Expression Prevalence unknown Difficult to diagnose b/c standardized tests are not particularly useful Generally involves a combination of difficulties with: Composing written text (grammar & punctuation errors) Poor paragraph organization Multiple spelling errors Excessively poor handwriting
Slide 22-

Assessment IQ tests correlate with & predict school achievement; a measure of academic intelligence IQ tests are relatively stable but not unchanging (stability increases with age) Heredity and environment influence IQ scores No test is free from cultural influences IQ is a score on a test – it is descriptive, not explanatory IQ fails to measure many factors – creativity, perseverance & discipline, social ability, etc.
Slide 23-

Tests of Intelligence Wechsler Scales (most common): Wechsler Preschool & Primary Scale of Intelligence WPPSI-III (2.6 – 7.3 yrs) Wechsler Intelligence Scale for Children WISC-IV (6.0 – 16.11 yrs) Wechsler Adult Intelligence Scale WAIS-III (16 – 89 yrs) Other commonly used scales: Stanford-Binet Intelligence Scale Kaufman Assessment Battery for Children Woodcock-Johnson Tests of Cognitive Ability, etc.

New Treatment Avenues in Dyslexia Fast Forward Computer based program to help kids to blend speech sounds (to speed the normal process of phonological manipulation) Learning Specialists To train children in strategies for decoding words (Lindamood/Bell, Orton Gillingham, Preventing Academic Failure, etc.) Accomodations 504, IEP
Slide 33-

Educational Support (1) Rehabilitation Act of 1973 (PL 93-112) Protects those w/disabilities from discrimination (physical, mental, emotional) in federally funded programs (e.g., schools) Established 504 “reasonable accommodation” An “accommodation” allows a student to complete the same assignment or test as other students, but with a change in timing, formatting, setting, scheduling, response and/or presentation. A “modification” is an adjustment to an assignment or a test that changes the standard or what the test assignment is supposed to measure.
Slide 34-

Educational Support (2) Typical 504 “Accommodations” or “Modifications” may include: Alternative books with similar concepts but at an easier reading level Audiotapes of textbooks Chapter summaries Shorter assignments focused on mastering the key concepts Substituting alternatives for written assignments (clay models, posters, collections, etc.) Providing a computer for written work (alpha smart)
Slide 35-

Educational Support (3) 504 “Accommodations” or “Modifications” cont’d: Alternative seating Using both oral and printed directions Providing visual aids Providing time for transitions Allowing additional time for tasks (e.g., homework) without a penalty Using worksheets that require minimal handwriting Reading test questions aloud Grading spelling separately from content Allowing use of a calculator for math
Slide 36-

Educational Support (4) PL 94-142 of 1975; reauthorized repeatedly as “Individuals with Disability Education Act” (PL 101-476) Guarantees a free and appropriate education to each child with a disability in every state and locality across the country Requires schools to provide a customized educational environment for learning disabled children Established the IEP (Individual Educational Plan) “Other Health Impaired” added in 1991 with IDEA Amendments/Reauthorization
Slide 37-

Educational Support (5) The IEP Process: Request or referral for an evaluation Child is evaluated (testing varies) Eligibility is decided IEP meeting is held IEP is written Services are provided Annual follow-up of progress (IEP meeting) Child is reevaluated (q3 years)
Slide 38-

Educational Support (6) Timing: 15 working days from request to school response 10 work weeks to complete testing and evaluation 10 working days to meet with the parents and IEP team upon completion of testing 10 working days for the parents to respond to the IEP meeting If the parents are unsatisfied, they can try and reach agreement with the school Parents can then request mediation Parents can then request due process Parents can write a letter of complaint to the DOE
Slide 39-

Educational Support (7) Contents of the IEP: Current performance Annual Goals Special Education and related services Participation with non-disabled children Participation in state/district tests Dates and places of service Transition services Measuring progress
