Neurospychoglogical assessment
neuropsychologival Assessment objectives
relationship between brain and behavior
assessment cognitive deficits
|| What is the nature and extent of the cog. imp,?
What, which how severe
||| What are the practical consequences of cog. imp?
|V in what way is an individuals mood and behaivior affected by brain lession?
| Is there evidence of organic brain dysfunction
Sometimes only on cog imp.
V Does cognitive preformance change over the time?
V| . What are cognitive strengths and weaknesses of an individual regarding the rehabilitation process?
Approaches of assessment
Laboratory examinations
MRI scan
spat 1 mm
SPECT and PET
Images of blood flow and activity of different brain areas
Radioactive update active parts
CT scan
2mm spatial
Hypodense are darker
Ventricles size atrophy or oedema
Angiography
X-ray contrast
Electroencephalography (EEG)
evoked potentials
primary cortical ways
Event-related potentials (ERPs)
secundairy cortical areeas
Doppler ultrasound
Detection of stenosis (narrowing) of an artery leading blood to the brain (internal carotid or vertebral artery)
Cerebrospinal fluid (CSF)
Lumbar punction
supports diagnosing
3 clinical interview
Questionarre and symotoms checklist
Clinical observations
Brief informal assessment basic cognition
Standardized tests
normative data
2 approaches
individual hypothesis testing
Big battery
When there is no previous information check
I. General demographic information
Individual’s best performance on any of the cognitive tests applied
III. Tests that are relatively resistant to the general effects of brain injury
National adult reading test
neurological examination
motor functions\
coordination
finger nose test
Roberg test
Reflex
cognition
Brief mental state examination
appropriate choice of measurement
Cultural sensitivity
non-verbal (eye-contact)
Culture fair test
Verbal communication
Good theoretical and practical knowledge of the measures used
Consideration of patients’ characteristics
Good knowledge of type and severity of disease and deficits
Consideration of referral question
Impaired comprehension makes test results invalid
