patterns in neurology

Question 1

broca’s aphasia

Answer 1

inferior frontal gyrus
nonfluent aphasia
comprehension good
assciated with contralateral hemiparesis if motor strip is involved

Question 2

wernicke’s aphasia

Answer 2

superior temporal gyrus
speech fluent but nonsensical
poor comprehension and awareness

Question 3

symptoms if CNS affected

Answer 3

increased spasticity/tone and reflexes

pyramidal pattern - arms have extensors weaker than flexors
legs have flexors weaker than extensors

opposite side of brain involved
same side of spine involved

brain- hemisensory and sensory level of spinal cord

Question 4

peripheral nervous system symptoms

Answer 4

decreased tone and reflexes

peripheral neuropathy- distal weakness
root/plexus/mononeuropathy- dependant on innervated muscles

plantar response- none/flexor= normal

Question 5

NMJ symptoms

Answer 5

ptosis/opthalmoplegia

decreased/normal tone and reflexes
fatiguablity

normal plantar response

Question 6

muscle symptoms

Answer 6

proximal wasting symmetrical

decreased/normal tone and reflexes

normal plantar response

Question 7

NMJ diffrential diagnosis

Answer 7

lambart- eaton- pre synaptic - autonomic features

Myaestenia gravis- post synaptic - occular

Question 8

peripheral neuropathy diffrentials

Answer 8

acute- GBS Guillain-Barré syndrome

chronic- diabetes/alcohol
