dr. coppola Flashcards
Rett syndrome
females
genetic disorder but not inherited
around 18 months, the locus coeruleus is not signaling with NE so there is bihemispheric diffuse dysfunction
corticobulbar tract
motor of non-occular CN’s
location of crossing
CST, light touch / proprioception (dorsal column): low medulla
pain / temperature (ALS): spinal cord right away
CN V, corticobulbar tract - pons
sensory cortex (postcentral gyrus) lesion
sensory dysfunction on the contralateral side
not-generalized delirium
look for coritcal lesion
change in level of consciousness
brainstem dysfunction or encephalopathy
Gerstmann syndrome
R-L confusion, finger agnosia, agraphia, acalculia, apraxia
no consciousness, memory, mood, or thought changes
due to lesion in left posterior hemisphere
MMSE
dementia screening
clock drawing
MoCA
more sensitive but longer
internuclear ophthalmoplegia (INO)
lesion of medial longitudinal fasciculus (MLF) that connects CN VI and CN III and allows for conjugate gaze
ipsilateral impaired ADduction, contralateral nystagmus
bell’s palsy
CN VII (peripheral) lesion
dysarthria
CN 7, 9, 10, 12
articulation errors
grading muscles
0 - nothing
1 - twitches but no contraction
2 - weak contraction but cant overcome gravity
3 - can overcome gravity but not resistance
4 - overcome light resistance
5 - full strength
innervation of muscle reflexes
biceps and brachioradialis - C5-C6 triceps - C6-7 patellar - L3-4 hamstring - L5 ankle - S1
dysdiadochokinesis
inability to perform rapid alternating movments
