NMS IV test 1 Flashcards
What are the functions of the posterior column
vibration, conscious proprioception, 2 point and light touch
What are the functions of the lateral spinothalamic tract
pain and temp (crosses at level)
What are the functions of the vestibular system
balance and spatial orientation
What are the functions of the cerebellar system
motor control coordinating voluntary movements
What are the functions of the Motor system - corticospinal tract
Carries motor and crosses in the brain stem
What are some characteristics of confusional states
Decreased level of consciousness, often reversible example head injury
What are some characteristics of dementias
Cognitive function and intellectual decline often irreversible example hemmorage or stroke
What would the patient complain of with a brain lesion
Mental status changes, HA, seizures, ICP visual compalaints
What would the patient complain of with a brainstem lesion
Crainial nerve deficitis
What would the patient complain of with a Pyramidal system lesion
uncoordinated voluntary actions
What would the patient complain of with an extrapyramidal system lesion
alterations in involuntary movements (athetosis, resting tumor, tics, dystonia)
What would the patient complain of with a cerebelllar lesion
uncoordinated motor movements; gait stance
What would the patient complain of with a spinal cord lesion
dissocation of sensory loss there may be LMN deficits if anterior horn or nerve root is also involved
What would the pt complain of with a peripheral NS lesion
dermatomal distrubution complaints, NTW
What neuro exam findind would be present with a brain lesion
mental status changes, motor/sensory deficits CONTRALATERAL to side of lesion (neuro signs/sx are dependent on where the lesion is located)
What neuro exam finding would be present with a brainstem lesion
CN deficits are usually IPSILATERAL, and motor/sensory deficits are CONTRALATERAL to the lesion (classical cross pattern)
What neuro exam finding would be present with an extrapyramidal lesion
resting tremors, chorea, athetosis, tics
What neuro exam finding would be present with a cerebellar lesion
ataxia and intention tremor Deficits are IPSILATERAL to the lesion past pointing, dysmentria
What neuro exam finding would be present with a spinal cord lesion
UMN signs, motor/sensory deficits IPSILATERAL to the lesion, pain/temp CONTRALATERAL to the lesion
What neuro exam finding would be present with a peripheral NS lesion
LMN signs flacid weakness, atrophy, fasculations hyporeflexia in dermatomal or plexus pattern
What are the 4 types of Aphasia
Brocca’s (poor speaking/caveman speech); Wernicke’s (poor comprehension), Conductive (pt has intact comprehension but can’t explain what they understood), Global (poor speaking and comprehension)
Anomia
inability to use or recognize names
Confabulations
the attempt to fill in memory gaps with false recollections
Dysarthria
disturbance of articulation
Dysphonia
inability/dysfunction of phonation; hoarseness
Dysmetria
disturbance of movement towards a target
Dysesthesia
disturbance of sensation
Paresthesia
sensation of tingling, pricking of numbmess
Ataxia (cerebella)
staggering, clumsy, drunken; seen in cerebellar disease, alcohol intoxication, and MS
Ataxia (Sensory)
Slappin foot gait, tabetic; commonly seen in posterior column diseases, tabes dorsalis, polyneuropathy
Ataxia (vestibular dysfunction)
broad based, festinating gait (parkinsons) Swining gait (hemiplegic/stroke)
Apraxia
inability to perform previously learned task
Agnosia
inability to recognize common stimuli (objects, colors, sound, etc.)
Astereognosis
inability to identify an object by touch
