Peripheral neurologic disorders, palsies Flashcards
what nerves have the ability to heal
PNS nerves
what is CRPS
complex regional pain syndrome
pain that is out of proportion or unprovoked within a region of the body
most commonly in distal limb
what is often associated with abnormal sensation, motor function, vasomotor or atrophy
CRPS
what are the types 1 CRPS
most common
patient has pain but no evidecne of peripheral nerve injury
what is type 2 CRPS
peripheral nerve injury that is evident
what is the presentation of CRPS
typically seen within 4-6 weeks s/p trauma
pain - burning/stinging pain
sensation changes
motor changes
trophic changes (increased hair growth, changes in nails, fibrosis of tissue)
will have patient with increased pain, erythema, swelling of affected area
what is neuropathy
nerve dysfunction that leads to numbness or weakness
what is polyneuropathy
affects multiple distal nerves - nerve dysfunction that leads to numbness or weakness
what is peripheral neuropathy
nerve dysfunction that leads to numbness or weakness but includes radiculopathies and/or mononeuropathies
what is compression neuropathy
compression on the nerve will cause changes in the microvascular function
will ultimately cause structural changes
most common at areas where nerve goes through tight area
what are the different types of radiculopathies
avulsion, stretch and rupture
what is B12 deficiency
present in neurologic symptoms in late findings
B12 helps to maintain the myelin sheath
what is the presentation with B12 deficiency
neuropathy
dementia
neuropsychiatric
optic nerve atrophy
what is Guillain-Barre syndome
post infectious autoimmune demyelinating disease
most common after respiratory or GI illness (4+weeks-ish)
progressive neurologic dysfunction
what is the progression of Guillian - Barre syndrome
tingling/weakness in the legs working its way up - may lead to paralysis of LE and can progress to respiratory compromise
