Neuromuscular Part Seven Flashcards
how should status epilepticus be treated
medical emergency
traumatic nerve injuries ranked least to worst
- neurapraxia
- axonotmesis
- neurotmesis
in general, what muscles are affected with myasthenia gravis
proximal
extraocular
facial
muscles of mastication
myasthenia gravis generally affects proximal or distal muscles
proximal
for polyneuropathy:
are arms or legs more affected
proximal or distal more
legs > arms
distal segments involved earlier than proximal
most common gait deviation with cerebellar issues
ataxic
what is asthenia
generalized weakness
describe a temporal lobe seizure
episodic changes in behavior
complex hallucinations
when is canalith repositioning treatment appropriate
horizontal SCC BPPV
posterior SCC BPPV
what is trigeminal neuralgia exacerbated by
stress/cold
what is vestibular neuronitis/labyrinthitis
acute infection with prolonged attack of symptoms (persists for several days or weeks)
what are Brandt-Daroff exercises for
residual or mild vertigo (BPPV)
generalized seizures AKA
grand mal seizures
what is nystagmus
involuntary, cyclical movement of the eyeball
what is Meniere’s disease
recurrent and usually progressive vestibular disease
episodic attacks (minutes-several hours)
for trigeminal neuralgia, are symptoms symmetrical or asymetrical
asymmetrical
what is trigeminal neuralgia relieved by
relaxation
for cerebellar lesions, what would be appropriate to assist decreasing ataxic movements
weighted waist belts
walkers
ankle cuffs, wrist cuffs
for cerebellar lesions, postural control is weakened in what group of muscles
proximal
consistent finding of meniere’s
edema of membranous labyrinth
what is status epilepticus
prolonged seizures/series of seizures lasting over 30 minutes with very little time between attacks
what is Wallerian degeneration
degeneration of the axon and myelin sheath distal to the site of axonal interuption
what should be done in the presence of a seizure
remain with patient
remove potentially harmful nearby objects
loosen restrictive clothing
do not restrain limbs
TURN HEAD TO SIDE/sidelying
what is neuralgia
pain along a nerve
what is epilepsy
recurrent seizures
what is a temporal lobe seizre preceded by
aura
etiology of myasthenia gravis
autoimmune antibody-mediated attack on Ach receptors at NMJ
classic LMN syndrome symptoms
weakness
hyporeflexia
hypotonia
atrophy
fatigue
what is myasthenic crisis
myasthenia gravis with respiratory failure
treat as medical emergency
is fatigue common with myasthenia gravis
YUP
what parts of the brain are involved for partial/focal seizures
only one part (symptoms specific to that area)
what is mononeuropathy
involvement of a single nerve
what is a petit mal seizure
posture is maintained
repetitive blinking or other small movements present
typically brief (last a few seconds)
what is ployneuropathy
bilateral symmetical involvement of peripheral nerves
difference between X1 and X2 paradigm
X1 - side-to-side eyes on stationary target
X2 - side-to-side eyes on moving target
what is radiculopathy
involvement of nerve roots
with cerebellar lesions, what type of tremor is present
intention
what divisions of the trigeminal nerve are most affected by trigeminal neuralgia
mandibular
maxillary
(opthalmic is rare)
what is the liberatory maneuver for
posterior SCC BPPV
what is vertigo
sensation of moving around in space or having objects move around a person
symptoms of generzlied/grand mal seizure
dramatic loss of consciousness
stiffening
rhythmic movement of arms and legs
eyes generally open
how long does a grand mal seizure last
2-5 minutes
do cerebellar lesions produce ipsilateral or contralateral symptoms
ipsilateral
what is myasthenia gravis
neuromuscular junction disorder characterized by
progressive muscular weakness
fatiagability on exertion
what is BPPV
brief attacks of vertigo and nystagmus that occur with certain head positions
symptoms of meniere’s disease
tinnitus
deafness
sensation of pressure/fullness within ear
