Q

Stimulant medication effects in ADHD

A

-Restores neural transmission of dopamine and noradrenaline in the prefrontal brain
-Large effects on behavioural symptoms of ADHD
-Effects on cognition are considerably smaller
-Lower doses are cognition-enhancing
-Higher doses are behaviourally activating but cognition impairing
-Only very small improvements in academic achievement but still lower than non ADHD peers

19
Q

promising neuropsychology based interventions for ADHD

A

-Exercise/ physically active lessons
-Strategy instruction
-Cognitive training
-Neuro-feedback

20
Q

Common referral reasons for a SNP evaluation

A

Children with:
-Past or recent head injury who is having academic or behavioural difficulties
-History of acquired or congenital brain damage
-Neuromuscular disease
-Brain tumour
-CNS infection or compromise
-History of a neurodevelopmental risk factor
-Returning to school after a head injury or neurological insult
-Documented rapid drop in academic achievement that cannot be explained by social-emotional or environmental causes

21
Q

Intellectual disability

A

Permanent condition originating sometime between birth and age 18
General intellectual functioning significantly below average (IQ of 70 or below)
Concurrent deficits in adaptive behavior
Need for neuropsychological assessment is rare

22
Q

Diagnostic criteria of ASD

A

-Persistent deficits in social communication and social interactions
-Restricted, repetitive patterns of behaviour, interest or activities
-Symptoms must be present in the early developmental period
-Symptoms cause clinically significant impairment in social, occupational, or other important areas of current functioning
-Disturbances are not better explained by ID or global developmental delay

23
Q

TBI and deficits

A

-Alertness and orientation
-Attention and concentration
-Intellectual functioning
-Language skills
-Academic achievement
-Adaptive behaviour and behavioural adjustment

24
Q

Anoxia

A

Absence of oxygen supply to organ tissues, including the brain

25
Q

Hypoxia

A

Decreased supply of oxygen to organ tissues

26
Q

Causes of anoxia/ hypoxia

A

Near drowning, strangulation, smoke/carbon dioxide inhalation, poisoning

27
Q

Anoxia/hypoxia can cause

A

Loss of consciousness, coma, seizures, death

28
Q

Symptoms of anoxia/hypoxia

A

mental confusion, personality regression, parietal lobe syndromes, amnesia, hallucinations, memory loss

29
Q

Genetic-32%
Electrophysical-35%

34
Q

35
Q

Symptoms of cerebral palsy

A

Ataxia
Spasticity
Weakness in one or more arm or leg
Walking on toes, crouched gait or scissored gait

Duchenne MD (Pseudo-hypertrophic)
Limb-girdle MD
Facioscapulohumeral MD (LandouzyDejerine)
Spinal MD

39
Q

Test battery modifications for children with visual impairments

A

-Administer verbal portions of standardized tests
-Administer nonverbal tests that require spatial manipulation and problem solving but not sight
-Administer a standardized or criterion-referenced test specifically designed to evaluate visually impaired children

40
Q

Test battery modifications for children with hearing impairments

A

-Have an interpreter use ASL if possible for verbal tasks
-Substitute written for oral language
-Give directions through pantomime, signing or gesture
-Use standardized nonverbal test

41
Q

Test battery modifications for children with receptive and expressive language impairments

A

-Establish that an adequate output channel exists (eg. pointing)
-Document expressive language deficits on standardized tests
-Use nonverbal tests
Give directions through pantomime and gesture

42
Q

Test battery modifications for children with motor impairments

A

-Assess overall cognitive ability with verbal and motor-free tasks
-Avoid speeded motor tasks
-test motor abilities without time constraints

43
Q

Strategies to address culturally different clients

A

-Test in clients language
-Test validated with clients population
-SNP’s should be aware of the tests reference population
-SNP’s should be aware of limitations of assessment practices and tests for a culture, including test bias, test fairness and cultural equivalence
