rapid screen for stroke
BE FAST

Time:
atypical synergies
predictable movement patterns occurring during voluntary OR as associated reactions. Thus, movements become “stereotypical” and restrictive of normal activities.
lumbar puncture diagnoses what conditions?
- inflam/infection: meningitis, encephalitis, MS
- subarachnoid hemorrhage
- pseudotumor cerebri (high opening pressure)
- cancer involving meninges
- INJECTING MEDS (chemo, anesth)
complications of lumbar puncture
post LP headache (positional)
bleeding
infection
back pain
(could rare: herniation, nerve injury)
CT is used for
acute: stroke, trauma
can see skull
vascular structures but NOT BRAINSTEM WELL
*radiation exposure
what is hyperdense and hypodense on CT
hyper: WHITE: bone
hypo: DARK: CSF, fat
BLOOD IS HYPERDENSE WHITE ON CT
what is hypodense on CT
stroke, edema, fluid, air
what is the best test for CNS diseases
MRI
infarcts, hemorrhages, vascular malformations, aneurysms, tumors, degenerative disorders, contusions, demyelination (MS), epilepsy, infections
DWI is what color in acute stroke
BRIGHT
what is myelography used for
visualization of subarachnoid space (via lumbar puncture)
spinal stenosis, cord AVM, tumor, abcess
conventional angiography is used for
occlusions, dissections, angiitis, aneurysms, vascular malformations
injection of thrombolytics
EEG is used for
seizures, brain death, encephalopathy, dementia, coma
VEP, BAEP, SSEP
visual: VEP: alternating checkerboard pattern
auditory: BAEP: auditory clicks through earphones
sensory: SSEP: Electrical stimuli applied to peripheral nerves
evoked potentials are used for
MS to find subclinical demyelination
brain lesions (BAEP)
acoustic neuroma (BAEP)
SCI (SSEP)
what is EMG?
Electromyography (EMG): Insertion of a small needle into individual muscles and recording of motor unit potentials at rest and with activity
