Chapter 10 - neuropsychological assessment and screening
Attention
TEACH
measures the subcomponents of attention
sustained attention
selective attention
divided attention
attentional switching
The main version is in fact called TEA but TEACH is the children's version
the only test that has manged to successfully divide the topic of attention into sub components
has been validated among patients with alzheimer, close head injury and stroke
Continuous performance test
measures sustained attention
During a stream of letters appearing onscreen, examinees are asked to press to click the mouse when a certain letter appears or appears after another letter
sensitive to wide range of brain-impairing conditions but are not good for diagnosis of attention-deficits disorders
executive functions
Wisconsin card sorting test
studies abstract thinking and ability to shift set
sorting cards based on unknown principle such as shape or color
has differential sensitivity to frontal lobe damage
Tinkertoy test
demonstrating executive capabilities in a structured examination
the examinees are asked to do whatever they want with 50 tinkertoy pieces
they are assessed on how intricate their designs are
number of pieces used
mobility of construction
symmetry
naming of it
Porteus maze test
measures planning and foresight
tracing a line without lifting the pencil through a series of more and more difficult maze tests
quite sensitive to brain damage in the frontal lobes
Aphasia
Token test
extremely sensitive to aphasia but simple for normal individuals
it's about completing oral commands with colored tokens
Spatial and manipulatory ability
Bender gestalt test
a test simply about copying a certain figure with erasing discouraged
focuses on accuracy rather than artistic prowess
a useful tool for screening for brain impairment
requires intact
accurate visual perception
correct sptial analysis
intact motor functions
executive abilities to make mid-course corrections
essentially a design copying test
Learning and memory
Weschler memory scales
extensive multiphasic memory test that has 9 subscales
Rey auditory verbal learning test
one of the oldest test ever
recalling a a 15 word list of words in the correct order
Motor problems
Beery 4
screen for visual-motor deficits that can lead to learning, behavior and neuropsychological problems
Finger-tapping test
a test of motor dexterity
normative expectation is that non-dominant hand will yield a tapping rate that is at least 90% of the dominant hand
Purdue pegboard test
place pegs in holes , using right hand , left hand , both hands
timed therefore slowing for one specific hand might indicate a lesion in the corresponding hemisphere while simultaneous task problems might mean diffuse or bilateral brain damage
general battery
Mini-mental state exam
%-10 min screening test that gives a global index of cogntive functioning among elderly
the most reliable test to this date to screen for dementia
items have to do with- orientation, immediate memory, attention, calculation, language production, language comprehension and design copying
