  3. Overview • I. Background • II. Pattern of Assets & Deficits • Casual Observations • Clinical Presentation • III. Developmental Course • IV. Treatment Interventions • V. Therapeutic Resources

  4. I. Background Hypothesizes – Rourke (1989) • 1. The Right side of the brain is generally more efficient at processing visual information (pictures, graphs, puzzles, maps). • 2. Children who had difficulty processing visual information had similarities with adults who had documented lesions on the Right side of the brain.

  5. I. Background Hypothesizes – (Rurke, 1989) Con’t • 3. White matter damage is the real causal agent • Right side of the brain is more dependent on interconnection with Left side and other parts of the brain to do its job. • Evidence – Children: hydrocephalus, receiving intra-cranial radiation, experienced severe localized (right) brain injury had more difficulty with visual information

  6. I. Background • NLD syndrome can develop: • Significant interference of Right Hemisphere • 1. General deterioration of white matter • 2. Substantial destruction of Right Hemisphere white matter • 3. Substantial interference of neuronal communication (e.g., Callosal Agenesis)

  7. Background • Definition: Nonverbal Learning Disability (NLD) is a neurodevelopmental disorder, manifesting in a pattern of neuropsychological, psychological, and academic deficits, which may vary in severity and time of onset, predominantly affecting the efficient and accurate processing of nonverbal information.

  8. I. Background • Essential Features • Neurodevelopmental • Pattern of Assets and Deficits • Severity and time of onset may vary

  9. I. Background • NLD NOT specifically listed in DSM-IV • Learning Disability – Not Otherwise Specified (LD – NOS)

  10. II. Patterns of Assets & Deficits‘Red Flags’ – Early Years • Sees ‘Trees for the Forrest’ • Perfectionist in work • Easily upset with minor change in plan • Play has to be on their terms • Subtraction / Division challenging (reversals) • Avoids sports / crafts, puzzles • Sees detail others do not – over focus • Poor concept of time – lifelong

  11. II. Patterns of Assets & Deficits‘Red Flags’ – Adolescent Years • Conversation may appear scripted • Friends are few; tend to be younger/older • Conversations: ‘Off-topic’ / intrusions • Literal (personalized) interpretation of events • Poor decision making when no ‘right answer’ • Does not or incorrectly perceive social cues • Good oral reading continues, but poor reading comprehension emerges • Poor rule application (formula) math/science • Poor interpretation of graphs / diagrams

  12. II. Pattern of Assets & Deficits‘Red Flags’ – Adult Years • Adulthood potentially more challenging: • more choice fewer rules • more ‘interpretation’, unique situations • More say in setting own agenda • Increased social isolation; stand out more • Job performance tied to degree of routine • Increased awareness of own ‘disorganization’, may become more rigid to increase control • May development Psychiatric disorder (s)

  13. II. Pattern of Assets & Deficits • Neuropsychological • Academic • Psychological Adjustment

  14. II. Pattern of Assets & Deficits •  Neuropsychological • Academic • Psychological Adjustment

  15. II. Pattern of Assets & DeficitsNeuropsychological • Language • Memory • Attention • Sensory-Perceptual (touch, manual skills) • Cognition (thinking, problem-solving)

  32. III. Developmental CourseRelative Functional Impairments

  33. IV. Differential Diagnoses • Nonverbal Learning Disability (NLD) • ADHD • Specific Mathematical Disorder (MD) • Dyscalculia • Autism Spectrum Disorder (ASD) • Remember – can have more than one problem

  34. Differential DiagnosisNLD Versus ADHD

  35. Differential DiagnosisNLD Versus MD

  36. Differential DiagnosisNLD Versus MD Con’t

  37. Differential DiagnosisNLD Versus ASD

  38. Differential DiagnosisNLD Versus ASD Con’t

  39. NLD is not ONLY about nonverbal information

  40. NLD is not ONLY about nonverbal information • Sequencing • Organization • Pattern Perception • Rule Generation and Application • Sifting : Essential Vs Non-essential • ‘Forrest from Trees’ • So why call it NLD ?

  41. Conceptual FrameworkFunctional Impairments

  42. Verbal  Nonverbal Take the 1st right on inbound Hwy 2, pass the 2nd toll booth, and exit immediately on outbound Hwy 3, and proceed to the 1st traffic light …….

  43. V. Therapeutic Interventions

  44. V. Therapeutic Interventions Neuropsychological Early years • Photo agenda / daily schedule • Reduce # of transitions • Verbal reminders before transitions • Rehearse ‘what to do’ for transition • Reduce distractions • Increase prediction

  45. V. Therapeutic InterventionsNeuropsychological • Ask for recall of instruction – OWN words • Color-code binders / dividers • Time-management sheets (order/ time)

  46. V. Therapeutic InterventionsNeuropsychological Critical Thinking • Highlight patterns / sequences • Highlight cause-effect • Highlight essential features to facilitate generalization • Practice ‘categorization tasks’ • Compare and contrast

  47. V. Therapeutic InterventionsAcademic - Math • ½ inch graph paper • Calculator • Written cue cards with procedural steps • Simple flow chart for procedural steps • N.Bley & C. Thornton (2003 – 4th Ed). Teaching mathematics to students with learning disabilities. Pro-Ed Publishers.

  48. V. Therapeutic InterventionsAcademic - Math • Encourage ‘talk through’ steps • Subtraction / Division (reversals) most challenging • Teach to segment word-based problems • Dyscalculia • www.dyscalculia.org

  49. V. Therapeutic InterventionsAcademic – Reading Comprehension • Preview unfamiliar vocabulary / questions • Offer thematic, preamble summary statement • SQ3R Method • Survey • Question • Read • Recite • Review • www.ucc.vt.edu/lynch/TROverview • www.resource.net/comprehension

  50. V. Therapeutic InterventionsPsychological • Highlight essential emotional features • What do you think the man felt? • Was the woman a little angry or a lot? • Why do you think the woman felt that way? • How are you feeling? Why do you feel that way? • Discuss character’s emotions (books, movies)
