-neurofibrillary tangles
s/s of alzheimers

-visuospatial problems
-language impairment
-behavior changes
diagnosis of alzheimers
clinical
-cerebral atrophy on imaging
treatment of alzheimers disease

rivastigmine
memantine
s/s of bells palsy
acute onset facial weakness
loss of taste
hyperacusis
bells palsy vs stroke
bells palsy: forehead does NOT wrinkle with raising eyebrows
stroke: forehead DOES wrinkle with raising eyebrows
diagnosis of bells palsy

types of stroke
-ischemic: thrombotic or embolic (MC d/t afib)
-hemorrhagic: intracerebral or subarachnoid
etiology of intracerebral hemorrhage
prolonged uncontrolled hypertension
s/sx of stroke
-facial drooping
-hemiparesis

-aphasia
-ataxia
-HA
-LOC
most important piece of info for stroke
last known normal
stroke workup
CT w/o contrast
treatment of ischemic stroke
-determine tpa eligibility
-bp less than 185/110 before tpa can be administered
-if not eligible for tpa, cant treat until bp is 220/120
IV nicardipine, IV clevidipine, IV labetalol
DO NOT LOWER MORE THAN 15% in 24HRS
treatment for intracerebral hemorrhage
SBP 150-220: reduce SBP to 130-140
If >220, not enough evidence to provide specific recommendations
Elkins slides
treatment of subarachnoid hemorrhage
reduce bp to 160
labetalol, nicardipine, or enalapril
Prevent vasospams w/ Nimodipine PO or NG for 3 weeks
TIA
stroke like symptoms that resolve in 1-2 hours
workup and treatment of TIA
same as stroke
s/s of vascular dementia
white matter lesions on MRI
management of vascular dementia
same as alzheimers
