1. The corpus callosum is the major commissure
that serves to integrate the functions of the two
cerebral hemispheres; it is a large bundle of
subcortical nerve fibers
2. The cerebral cortex, the outer
most layer of the brain, is the
source of the highest levels of
sensory, motor, and cognitive
processing
AKA Neocortex
FRONTAL LOBE = motor control ;
PARIETAL LOBE = processing of
touch/somatosensory info ;
OCCIPITAL LOBE = visual
perception; TEMPORAL LOBE =
essential to processing of
auditory info
3. DIVIDED ATTENTION - AKA distributed
attention, pertains to the ability to shift back
and forth between two or more tasks -->
SUSTAINED ATTENTION - refers to the
ability to sustain attention relatively over
periods of time
4. Cerebellum - sits just below the
cerebrum at the back of the brain,
and helps coordinate muscle tone,
posture, and hand and eye
movement.
Damage to the cerebellum can
cause a variety of motor
disorders; slurred hesitant
speech known as DYSARTHIA
may be a symptom of
cerebellar damage
5. The most common syndrome
cause by damage to the BASAL
GANGLIA is PARKINSON'S
DISEASE
The BASAL GANGLIA consist of a
collection of nuclei in the forebrain
that makes connections with the
cerebral cortex above the thalamus
below
6. The hippocampus and amygdala in the
temporal lobe appear to be involved in
various aspects of memory and learning
7. BROCA'S AREA is just in front of the
motor cortex in the left hemisphere, and
BROCA'S APHASIA causes those with it to
have difficulty enunciating words, although
they have no problem understanding written
or spoken language
WERNICKE'S AREA is located in the upper and rearward
portion of the left temporal lobe, and those with
WERNICKE'S APHASIA have no difficulty perceiving
words, but cannot associate the words with their
underlying meaning; they appear unable to comprehend
spoken or written language
8. CONSTRUCTIONAL DYSPRAXIA is the impaired ability
to deal with spatial relationships either in a two or three
dimensional framework
9. Damage to the association cortex of
the occipital lobes may cause VISUAL
AGNOSIA which is a difficulty in the
recognition of drawings, objects, or faces
10. Executive functions are
substantially, but not
exclusively, underwritten in the
frontal lobes
Although it is true that disturbances in
executive functions can arise from a
variety of neurological conditions, in the
vast majority of cases the frontal lobe
is implicated
11. One of the most widely used fixed batteriesthe
HALSTEAD-REITAN NEUROPSYCHOLOGICAL BATTERY is a
set of tests that include the finger-tapping test, seashore
rhythm test, trail making, tactile form recognition, category test,
and more
12. The INTERMEDIATE VISUAL AND AUDITORY
CONTINUOUS PERFORMANCE TEST is normed on 781 people
ranging from 5-90 years of age and screened for attention deficit,
learning difficulties, emotional problems, and medication use
13. the WECHSLER MEMORY
SCALE III - 10 primary subtests are
described in Table 10.6, and these
constitute the basis for obtained
age-adjusted scaled scores
14. A clinical examination for
aphasia has the advantages of
simplicity, flexibility, and brevity
Certain elements are assessed: 1.
Spontaneous speech (word-finding
difficulty or neologisms), 2. Repetition of
sentences and phrases, 3.
Comprehension of spoken language, 4.
Word finding, 5. Reading, 6. Writing and
copying, 7. CALCULATION
These tasks are so simple that normal
subjects almost never fail them
15. APRAXIA refers to a
variety of dysfunctions
characterized by a
breakdown in the direction or
execution of complex motor
acts
16. Many neuropsychologists analyze executive functioning
by using the clinical method to evaluate executive functions
instead of administering formal test; they use interview and
observations to fill out the structured checklist on executive
functions
17. Normative
expectation is that the
nondominant hand will
yield a tapping rate of
only 90% of the dominant
hand
18. The CAGE questionnnaire is a
short screening tool that consists of
asking the client CAGE; have they
thought about 1. Cutting down on
drinking 2. becoming Annoyed by
criticism of drinking, 3. felt Guilty
about drinking, or 4. had an
Eye-opener drink in the morning
19. The MENTAL STATUS
EXAMINATION is a loosely structured
interview that usually PRECEDES
other forms of psychological and
medical assessment
The purpose is to provide an accurate
description of the patient's functioning in
the realms of orientation, memory,
thought, feeling, and judgment; equivalent
of the general physical examination
Most commonly
assessed are elderly,
especially those who
might have AD
20. Mini mental state exam is the most widely used
mental status tool; the reliability of this instrument is
excellent; 23 or below is abnormal; it is about 80-90%
accurate in identifying those suspected to have AD
