what TIA symptoms would carotid stenosis cause?
MCA syndrome; aphasia, dysarthria, altered LOC
what TIA symptoms would vertebrobasilar stenosis cause?

why is thiamine given before IV dextrose when wernicke’s encephalopathy suspected for hypoglycemia and seizure activity?
Thiamine is requires for cellular activity for aerobic metabolism. if glucose is given with thiamine deficiency, anaerobic metabolism occurs with increase pyruvate levels leading to lactic acidosis.
pathophysiology for myasthenia gravis
autoimmune disorder
reduction of acetylcholine receptor sites at neuromuscular junction
pathophysiology of multiple sclerosis
autoimmune disease
disruption of myelin sheaths that is crucial for transmission of nerve signals; leads to numbness, weakness, loss of muscle coordination, problems with vision, speech and bladder control
Multiple sclerosis pharmacological management
Steroids for acute relapse recovery
antispasmodics
interferon therapy, immunosuppressive therapy
PLEX
MG pharmacology
Mestinon (pyridostigmine): anticholinesterase drugs: block breakdown of acetylcholine; symptomatic improvement
Gullian Barre CSF results
elevated protein; immunoglobulin G
