week 7 Flashcards
specific learning disorder
neurodevelopmental origin, different processing info
math, read, write
10% pop, many have ADHD
dysgraphia = writing
dyscalculia
dyslexia
aetiology of specific learning disorders
unknown cause of LDs, tho many genetic, congenital, neurobiological factors
learning disorders are SPECIFIC, different than ID
lifelong, tho impact can vary
have low academic achievement in one area, can inc w extreme effort
symptoms of LD
neurological soft signs: CNS dyfunction that cannot be picked up on w neuro tests
- behavioural: i.e. attention deficits, hyperactivity
- perceptual: i.e. vis differentiation of letters and words
- motor: balance, twitching
immature body image and agnosias: unable to ID body parts are surfaces, L/R
- finger agnosia: don’t recog own finger
poor spatial organization
associated overflow movements: can’t keep opp limbs tatic when do task w other side
motor proficiency problems
activity deficit phenomenon: adopt sedentary lifestyle bcs avoidance coping
diagnosis learning disability
DSM-5 symptoms:
1. difficulty in area for 6+ months: reading, interpret, spelling, numbers
2. poor academics and everyday trouble
3. issues start at school age
4. learning diffs not due to other causes i.e. ID
subtypes of learning disabilities
- language imapired w subtle motor difficulties in info processing: prefer visual learning
- visual-spatial-motor impaired w perceptual motor issues and clumsiness: auditory learning
- diff w math, sometimes language
ADHD
neurobiological origin, ID in early school yrs
- most are comorbid w LD, but is NOT a learning dis
ADHD brain differences
frontal lobe
basal ganglia: coordinated mvmnt, suppression
reticular activating system: direct attention
brain stem
major NT systems
DSM-5 diagnosis ADHD
6+ symptoms inattention and/or hyperactivity when under 16
5+ symptoms if 17+
3 types of ADHD
- predominantly inattentive
- predominantly hyperactivity-impulsive
- combined subtype
tourette syndrome
neurodevelopmental or brain based condition, causes invol sounds and mvmnts
sudden, repetitive, unpredictable
- inc w stress
sporadic tourette syndrome
no genetic link found
causes of tourettes
no specific gene, may be combo
abnormal dopamine
types of tics
simple vocal tic: clear throat, yell, click
complex vocal: words and phrases, echoalia, coprolalia (obscene words)
simple motor: blink, head jerk
complex motor: jump, twirl, imitate behaviour
management of tourette’s
medication: start w trial
- fatigue, restless, withdrawal
- can cause depression
psychotherapy
behavioural therapy: i.e. active breaks, substitute to manageable tic
qualities of good teaching environ
routine is necessary for IDs
- space reduction, discrete boundaries, small teams
learning stations effective bcs flexible
peer instruction
community programs
