TRANSIENT GLOBAL AMNESIA
בילבול ופגיעה בזיכרון לטווח קצר- רק קצר ובאנטרוגרדי. שואלים שוב ושוב את אותה השאלה!
lacunar stroke
presentation
1 Pure motor stroke/hemiparesis 2 Ataxic hemiparesis - (bailar part of pons, more...) 3 Dysarthria/clumsy hand 4 Pure sensory stroke 5 Mixed sensorimotor stroke
progressive, usually asymptomatic
lacunar stroke
causes
asymptomatic present
ct or mri
result from lipohyalinosis of small resistance vessels, usually CHRONIC HYPERTENSION
found in approximately 10% of brains at autopsy
not seen on CT or MRI
when will you suspect a lacunar infarct?
solated nature of the neurologic
deficit makes the clinical picture of lacunar infarction distinctive
Anosognosia
asomatognosia
types of neglect
SAH LAB DIAGNOSIS METHOD
first - CT. sensetive for the first day (90%)
if negative - LP!!! most sensetive!
levodopa side effects
nausea, vomiting, hypotension, abnormal movements (dyskinesias), restlessness, and confusion. Cardiac arrhythmias
amantadine side effects
for mild parkinsonism
(restlessness, confusion, skin rashes, edema, disturbances of cardiac rhythm
when carbamezapine should be discontinued?
total neutrophil count falls
below 1,500/mL or if aplastic anemia is suspected
cryptococcal clincal findings
headache, confusion, stiff neck, fever, nausea and vomiting, seizures, and CRANIAL NERVE PALSIES
THALAMIC PAIN
כאב שורף בצד קונטרא לטראלי.
מופיע לאחר התאוששות מחסר סנסורי בגלל שבץ.
יכול להיות גם בגלל פגיעה באונה פריאטלית או אחת המסילות הסנסוריות.
טיפול - משככי כאבים, נוגד פרכוס (קרבמזפין/ פניטואין) או נוגדי דיכאון.
Dejerine-Roussy syndrome.
sensory loss, spontaneous pain, and perverted cutaneous sensation has
parietal lobe or the sensory
pathways at any point in the cord (posterior columns or
spinothalamic tract) or in the brainstem. Treatment with
analgesics, anticonvulsants (carbamazepine or phenytoin),
or antidepressants and phenothiazines in combination is
occasionally helpful.
adies pupil
dilated pupil (mydriasis) which does not constrict in response to light, loss of deep tendon reflexes, and abnormalities of sweating
light-near dissociation (no light reaction but accomadation)
damage to the postganglionic fibers of the parasympathetic innervation of the eye, usually by a viral or bacterial infection
status epilepticus treatment
1 diazepam 2 phenytoin 3 more phenytoin 4 phenobarbital 5 phenobarbital - general anesthesia
pupil size
pons herniation vs pons lesion
herniation - midsize
lesion - pin point!
