Latest research on Learning Disorders
According to the Diagnostic and Statistical Manual for Primary Care (DSM-PC) Child and
Adolescent Version
(Wolraich, M. (Ed.) 1996)
, the following are the definitions for
Learning variations and problems:
Initial Visit
- History from the child:
- History from Parent
- Any extra help received: what subjects, which grades, how much help
- History of ever being retained or recommended for retention
- Extracurricular activities
- Socialization
- Behavior
- Classroom factors: number of children; multiple changes of teacher/school;
disruptive children or bullies; open classroom (several classes in one large space with movable dividers)
- Parent attitude expressed towards school/teacher
- Screen for level of functioning (See Screening below)
- Check hearing and vision
- Check for associated behavioral disturbances
- Review Differential Diagnosis
- Assess for Co-morbidities especially ADHD
- If you suspect a learning disability:
Screening
- First, determine the child's actual abilities to read, write and do math.
- Letter grades may not accurately reflect abilities (e.g. child being
"passed along" or child is in special education). Reading- Have child read a paragraph starting at lower
grade level if this is an area of concern. Watch which words are not read or pronounced or skipped over.
Help child decode words and see if he or she can sound out or blend sounds
(See Skills Needed for Decoding pt).
- Cover the page and ask some comprehension questions. Be empathic about
difficulties reading. or use WRAT or Einstein or Durrell.
- Writing- Have child write the alphabet in lower case letters. Look for speed,
letter reversals, skipped letters, spacing. For older child have them write the alphabet in cursive.
Have child write several sentences "about anything you want to". Assess grammar, punctuation, content,
spelling and complexity of thoughts written.
- Math- Ask child what he has been learning in math and start with functions below that.
- mathematic calculations (See Difficulty With Math pt)
- mathematic reasoning (See Difficulty With Math pt)
- Kindergarten and first grade: single column addition and subtraction
- Second grade: borrowing and carrying (called regrouping)
- Third grade: multiplying and dividing
- Fourth grade: adding and multiplying fractions
- Fifth grade: decimals and finding the unknown (algebra)
- Sixth grade: least common denominator, mixed numbers, negative numbers
- Fine motor skills: DAP (draw a person), Family Kinetic drawing (draw everyone in your
family doing something), Gessell figures, Beery
- Memory: ask child to recall 3 things at the beginning of the visit and re-request them
at the end of the visit
- Language assessment: assess articulation, thought clarity, complexity of language
structures from spontaneous conversation about school (above). If concerns, use Complex Sentences
task from PEEX exam; use coins to assess understanding of commands e.g. put the biggest coin
between you and me.
- Attention and sequencing: Verbal Instructions task of the PEEX, multiple step
commands in the exam room. Also collect standard checklists (See also: Attention/Activity Level DTW)
Writing Assessment: Motor Component (See:
Common Handwriting Problems and Solutions pt,
Classroom accommodations for children with handwriting problems pt)
Watch the child write a sentence or paragraph and observe:
- Common grasp mistakes
- Holding the pencil straight up in the air
- Writing with open hand or fingers straight
- Wraps thumb around the pencil
- Holding pencil too close or too far from the tip
- Movement of arm when they write
- Not putting a space between words
- Writing too hard
- Writing too soft
- Letter and number reversal
- Poor posture
- Poor paper placement
- Not stabilizing paper with other hand
- Face too close to paper suggesting poor vision
Writing Assessment
- Substance
Abuse[note]
- Sensory Impairment
- Hearing Problem
- Visual Disturbance
- Mental
Retardation[note]
- Pervasive Developmental Disorder
- Developmental Coordination Disorder
- ADHD[note]
- Oppositional Defiant Disorder / Conduct Disorder
- Environmental factors: poor educational stimulation or deprivational
home environment
- Psychosocial factors: lack of motivation, ethnic/racial bias in testing,
social skills deficits, school failure
- School Failure
- Separation Anxiety Disorder/School Phobia/ General Anxiety
- May be secondary to avoiding embarrassment in classes by not
being able to express themselves, or not wanting to talk in class.
- Children with LD are also more likely to complain of somatic symptoms,
which would keep them home from school such as headaches and stomachaches
- ADHD
- 20-25% of reading-disabled children have ADHD.
- 10-50% of children with ADHD have a reading disability.
- Depression
- Children with learning disabilities are more likely to have a
negative self-esteem, report higher rates of depression, and are more likely
to internalize failures as reflecting on their overall worth.
- Oppositional Defiant Disorder/
Conduct Disorder
- Developmental Coordination Disorder
- Communication Disorder
- Although early language and articulation disorders place a child at
risk for reading disorders, if therapy is instituted before first grade and there
is no further evidence of the language disorder, they may have normal development
of reading. However, they may still show subtle dysfunctions which will manifest
in ability to follow directions and in social skills
- Social Skills Deficits
- Mental Retardation
- Children with mental retardation can also have specific learning
disabilities relative to their degree of retardation
