Patterns of neuro dysfunction* Flashcards
upper motor neurone symptoms
increased tone
brisk reflexes
weak extensors in the arms
weak flexors in the legs
LMN signs
wasting fasciculations decreased tone decreased or absent reflexes flexor plantars
muscle disease
proximal wasting, normal or decreased tone
normal tendon reflexes
no sensory symptoms
NMJ
fatigue weakness normal or decreased tone normal tendon reflexes no sensory symptoms
functional weakness
no wasting normla tone normal reflexes erratic power non anatomical loss
UMN causes
acute stroke
SOL
spinal cord problems
hemiparesis UMN
contralateral pyramidal weakness in the face, arms and legs
flexors in the upper limb are stronger than the extensors
pyramidal weakness UMN
pyramidal weakness LMN
flexors are stronger
extensors are stronger
parasagittal frontal lobe lesion (UMN)
paraparesis - partial paralysis of the lower limbs
spinal cord lesion (UMN)
pyramidal weakness below the lesion
cervical - arms and legs
lumbar - legs
flexors are stronger
LMN lesions - summer polyneuropathy
weakness and sensory symptoms
complication of DM, alcohol, metabolic, genetic
LMN - mononeuropathy
nevre compression
mononeuritis multiplex (assym polyneuropathy)
DM
vasculitis
length dependent neuropathy leads to what
storing and later glove sensory loss
dissociated sensory loss
loss of spinothalmic but preservation of dorsal column - hemicord damage (brown squared)
