  1. Breaking through the Barriers: How Adults with Dyslexia Made Significant Improvements in Phonological Processing, Reading, Spelling and Writing Skills.

  2. WHAT DYSLEXIA IS NOTDYSLEXIA… • .. is NOT A VISUAL PROBLEM • .. is NOT A LACK OF INTELLIGENCE • .. is NOT DUE TO LACK OF EFFORT • .. is NOTA DEVELOPMENTAL LAG • .. is NOT UNCOMMON: 5–17.5 % OF POPULATION • ..is NOT IMPROVED BY STANDARD READING INSTRUCTION

  3. Learning Difficulty or Dyslexia • Dyslexia => Dys = difficulty & lexia = words • Poor skills in Reading • Neurological in origin • Lifelong, but environment may alter course • Core deficit = “phonological language skills” • Accompanying Challenges (~50%) • ADHD • Sensorimotor • Behavior problems = More challenging to remediate

  4. “CAN WE MAKE CHANGES IN NEURAL SYNAPSES or NETWORKS?” AT WHAT AGE DO HUMAN NEURONS LOSE THE ABILITY TO MAKE NEW CONNECTIONS (SYNAPSES) WITH OTHER NEURONS?

  13. From Genes to Behavior in Developmental Dyslexia. Galaburda AM, LoTurco J, Ramus F, Fitch RH, Rosen GD.Nat Neurosci. 2006 Oct;9(10):1213-7. All four genes thus far linked to developmental dyslexia participate in brain development, and abnormalities in brain development are increasingly reported in dyslexia. Comparable abnormalities induced in young rodent brains cause auditory and cognitive deficits, underscoring the potential relevance of these brain changes to dyslexia. Our perspective on dyslexia is that some of the brain changes cause phonological processing abnormalities as well as auditory processing abnormalities; the latter, we speculate, resolve in a proportion of individuals during development, but contribute early on to the phonological disorder in dyslexia. Thus, we propose a tentative pathway between a genetic effect, developmental brain changes, and perceptual and cognitive deficits associated with dyslexia.

  15. Is there a Neurobiological Basis to Dyslexia?

  16. Could Dyslexia Affect More Than Language Skills?

  18. Intellect Development Development Systems (Williams & Shellenberger, 1996)

  19. Dyslexia may involve a wide range of behaviors or developmental abilities, besides reading. However, adults may “select” occupations or environments that put limited demands on their weaker skills.

  20. Interdisciplinary Approach to Assessment and Treatment • Two or more disciplines combine/coordinate their knowledge to improve “weak” skills. • Degree of shared knowledge across disciplines • Common understanding of the others’ expertise • Shared theoretical model and vocabulary

  28. Interdisciplinary Assessment & Treatment of Learning Disabilities Overview of Services • Intake/Screening Appointment • Phase I Assessment • Phase II Assessment • Treatment • Post-treatment Assessment • Follow-up/Generalization

  29. Interdisciplinary Treatment Program • Key treatment features are based on neuroscience and behavioral treatment research findings • Intensity (# of hours per day) • Frequency (# of days per week) • Specificity (clarity of treatment program) • Ongoing data collection of program effects for program self-evaluation • Selective post-treatment assessment with standardized tests to document treatment gains

  30. Interdisciplinary Assessment and Treatment Goals • Identify and then improve weak skills to develop new strengths in: • Language • Sensorimotor • Cognition/attention • Behavior • Develop independent functioning in language, sensory-motor, behavior & achievement, relative to an individual’s true potential. • Provide essential “tools” for success in academic, occupational and interpersonal domains of life.

  32. Treatment - Case Study • High school student • History of dyslexia • Years of school-based academic intervention • Years of reading tutoring • commercial centers, by private 1:1 tutors… • a family member was an ESE Reading Specialist • A first-team athlete • Weak skills in: • reading (>5 years below grade), writing & spelling • comprehension • auditory and visual memory • visual-spatial • attention

  33. Treatment - Case study • Interdisciplinary Phase I & II assessments identified weaknesses in: • Language • poor phonological processing, reading, spelling and comprehension • Occupational Therapy • sensory integration deficits including poor praxis, vestibular, visual vigilance, visual tracking, and visual processing • Medical • poor attention, as exhibited by difficulty maintaining attention to relevant visual and auditory stimuli

  34. Interdisciplinary Treatment Program • Individualized, interdisciplinary treatment • Speech-Language Therapy • Occupational Therapy • Clinical Psychology/Counseling • Intensive, Frequent and Explicit Treatment • 22-25 hours of language treatment per week • 5 days/week for 4-5 hours/day • 1 hour of counseling per week • 1 hour of parent education per week • 5 hours of occupational therapy per week • 12 weeks of 1:1 interdisciplinary treatment • (duration of treatment is client dependent)

  35. Documented Treatment Results • Selective re-administration of pre-treatment standardized, nationally normed-tests for measurement of post-treatment gains. • Graphical representation shows pre-treatment scores as blue stars and post-treatment scores as green stars • Green arrows indicating areas of significant gain or improvement.

  40. Future Directions • Test explicit training of sight word skills and fluency training, AFTER successfully retraining phonological awareness. • However, explicit fluency training was not needed for remediated children; they needed more practice for automaticity of skills. • Test training visual memory to improve orthographic spelling skills.
