Neuro Flashcards
What is MS?
Chronic auto-immune
demyelination of the white matter, brain and spinal cord
20-40
Women more common
ALS (Lou Gerigs)
Paralysis of voluntary muscles
40-60
Men more common
Tx is symptomatic, no cure
Guillain-Barre’
Reversible ascending paralysis that happens gradually
Acute inflammation disorder
Medications: steroids, plasmapheresis- immunoglobulin, analgesics
Myasthenia Gravis
Nerve impulses fail to cross the myoneural junction
Loss of acetylcholine (ACh) receptors
Autoimmune
Interventions: meds- anticholinesterases to increase amount of acetylcholine (pyridostigmine, nesternone), steroids,
Get things done in the morning bc fatigue gets worse throughout the day
Spinal shock
Temporary, sudden loss of reflex activity below the level of injury after spinal cord injury, temporary inflammatory response
Neurogenic shock
Massive vasodilation –> Above T6, venous pooling, extreme hypotension
All blood is going to extremities and not getting pumped back to the heart, causing hypotension
Treatment: fluids, vasoactive drugs to increase BP
Autonomic Dysreflexia
Exaggerated sympathetic response to noxious stimuli
It is characterized by paroxysmal HTN (the sudden onset of severe high blood pressure) associated with throbbing HEADACHE, profuse SWEATING, nasal stuffiness, flushing of the skin above the level of the lesion, BRADYCARDIA, anxiety, and sometimes by cognitive impairment
check bladder–>bladder scan
Autonomic dysreflexia is caused by an irritant below the level of injury, usually related to bladder or bowel
MS: clinical manifestations and Tx
Limited mobility, with fatigue, and visual disturbances, weakness, numbness, dysarthria (difficulty speaking), dysphagia, ataxia (unsteady gait) , sexual dysfunctions, nystagmus, spastic bladder
Tx: no cure or specific treatment - corticosteroids for symptomatic relief, immunosuppressants, baclofen for muscle spasticity
ALS: Clinical manifestations
Fatigue, cramps, twitching, loss of coordination
Slurred or nasal speech with dysarthria
Death occurs from failure of the respiratory system.
Myasthenia Gravis: Clinical manifestations
Drooping eye
Vision, breathing, swallowing, chewing, head control- most affected
Respiratory failure is the primary challenge.
fatigue increases as the day progresses
Tensilon test for diagnosis
Brain requirements
Glucose
O2
Blood (regulated by CO2)
Low ICP (
Migraine
chronic, throbbing 4-72 hours Auras may precede Women want to be in a dark room and not move Triptan meds
Cluster headache
seasonal (4-12 weeks) non-throbbing (usually around eye) 30 min-2 hours Men 20-50 yrs old Feels better with movement, oxygen and calcium channel blockers
What to note during a seizure
Order of activity, when it started, how long it lasted
Acute seizure meds
Lorazepam (IV) ativan
Diazepam (IV) valium
Diastat (Rectal)
Phenytoin (dilantin) or Fosphenytoin (IV)
