Ch. 2 Neurologic Assessment Flashcards
True or False:
Most pts have received a neurological exam conducted by a neurologist before they get to the SLP.
True
Which are the parts of a Neurological Exam?
- Cranial Nerves
- Visual Field Assessment
- Motor System Evaluation
- Somesthetic Sensation
- Eval. equilibrium (dizziness, and vertigo)
- Conscioussness and Mental Status
- Laboratory Tests
In visual field assessment, information from the right side visual space goes to the ______ of each retina.
Left side
The _______ of each retina connects to the ______ in the _________.
Left side, visual cortex, left hemisphere
Info from the left-side visual space goes to the ______ of each retina
right side
loss of vision in one-half of the visual field is called:
hemianopia
HEMIANOPIA means
Half vision/ half blindness
When the same part of the visual field is affected in each eye is called:
Homonymous Hemianopia (Hemianopsia)
When/where does the lesion for HOMONYMOUS hemianopia occurs? C
if a lesion destroys the OPTIC TRACT POSTERIOR to the OPTIC CHIASM
When/where does the lesion for HEMIANOPIA occurs? B
if a lesion destroys the CROSSING FIBERS AT the OPTICAL CHIASM
Lesions in the optic nerve causes:
blindness
HOMONYMOUS means
the same part of the visual field is affected in each eye
MOTOR SYSTEM evaluation includes:
evaluating movement, reflexes, muscle tone & range of motion, muscle strength, volitional movements, gait, somesthetic sensation, equilibrium, including dizziness & vertigo, consciousness and mental status.
SOMESTHETIC SENSATION refers to:
sensory awareness of body
When Evaluating Consciousness & Mental Status, you are also looking at:
confusion, attention & concentration, mood, orientation
Name some of the different types of RADIOLOGIC IMAGING STUDIES
Cerebral Angiography and Computerized tomography (CT Scan)
The study where die is injected into veins and arteries – usually carotid artery to detect occlusions in blood vessels is called:
Cerebral Angiography
TRUE OR FALSE…. Can CEREBRAL ANGIOGRAPHY also see narrowed, but not occluded, vessels as they fill slowly?
TRUE
What is STENOSIS?
The narrowing of vessels is called stenosis (of any structure-not just arteries).
The narrowing of vessels is called?
Stenosis
It allows visualization of soft tissue that can’t be seen on regular x-rays. Main disadvantage is that pt is exposed to radiation
Computerized tomography (CT Scan)
Main disadvantage of CT Scans
Pt is exposed to RADIATION
MAIN disadvantage of RADIOLOGIC IMAGING STUDIES
PT Expose to RADIATION
Name some NON-RADIOLOGIC IMAGING STUDIES
Magnetic Resonance Imaging (MRI) and Positron emission tomography (PET) scans,
