Week 1-3 Review (neuro) Flashcards
agnosia
inability to recognize familiar objects with one sense (ex: sight)
akinesia
inability to initiate movement (common in Parkinson’s)
apraxia
inability to perform previously learned task (ideational = doesn’t get it, ideomotor = cannot do the task)
asynergia
inability to move muscles together in a coordinated manner
athetosis
slow, worm-like, twisting motions (common in CP)
causalgia
painful, burning sensations common in CRPS type 1
chorea
rapid, involuntary, jerky movements (common in Huntington’s)
decorticate rigidity
contraction of UE flexors and LE extensors (damage of motor tracts above red nucleus in midbrain)
dysdiadochokinesia
impaired rapid alternating movements (common in cerebellar disorders)
dysmetria
inability to judge distances (common in cerebellar dysfunction)
Horner’s syndrome
drooping of eyelid, constriction of pupil, lack of sweating (damage to sympathetic tract)
somatagnosia
lack of awareness of relationship of one’s own body parts or the body parts of others
homonymous hemianopsia
damage to optic TRACT (loss of half of visual FIELD)
bitemporal hemianopsia
damage to optic CHIASM (loss of peripheral vision), tunnel vision
monocular blindness
damage to the optic NERVE (loss of vision in one eye)
MCA stroke deficits
- MOST COMMON STROKE
- contralateral sensory/motor deficits in FACE and UE
- aphasia (dominant)/perceptual problems (non-dom)
- contralateral homonymous hemianopsia
- main branch –> global aphasia
ACA stroke deficits
- sensory/motor deficits in LE
- urinary incontinence
- mental deficits (confusion, amnesia, apathy, short attention span)
PCA stroke deficits
- visual deficits (HH, visual agnosia, prosopagnosia)
- aphasia
- thalamic pain syndrome
- hemiplegia if cerebral peduncle involved
vertebral-basilar stroke deficits
- locked-in syndrome (quadriparxsis and bulbar palsy) or death from edema
- other symptoms: vertigo, coma, diplopia, nausea, dysphagia, ataxia, cranial nerve impairments
anterior inferior cerebellar stroke deficits
- Horner’s syndrome, lateral gaze deficits, unilateral deafness
- contralateral loss of pain and temperature
- vertigo, ataxia, nystagmus
superior cerebellar stroke deficits
- severe ataxia
- contralateral loss of pain and temperature
- dysarthria, dysmetria
posterior inferior cerebellar stroke deficits
- Wallenberg’s syndrome (vertigo, nausea, hoarseness, dysphasia, ptosis)
- impairment of sensation in ipsilateral face and contralateral torso and limbs
- possible Horner’s syndrome
flexion synergy UE
scapular elevation and retraction
shoulder abduction and external rotation
elbow flexion
forearm supination and wrist/finger flexion
flexion synergy LE
hip flexion, abduction, external rotation
knee flexion
ankle dorsiflexion and inversion
great toe extension
