CN VII deficits?
facial paralysis
loss of taste
hyperacusis (sensitivity to certain freq)
Receptive aphagia vs expressive aphagia?
Receptive - deficit in Wernicke’s area, can’t understand but can speak fluently
Expressive - deficit in Broca’s, can understand but can’t speak.
Lower motor neuron vs upper motor neuron deficit?
LMN: hypotonia, fasciculations (spontaneous flicker of movment), atrophy
UMN: spasticity (tightness), lack of atrophy
