Neglect syndromes where in brain?
R parietal
argyll-robertson
accommodation reflex present
PSP areas affected?
brainstem, subthalamic nucleus, BG, cortical areas, dentate n
Richardson syndrome - what is it? how does it present?
clinical phenotype of PSP
vertical supranuclear gaze palsy (particularly downwards)
postural instability
subcortical frontal dementia
pathology in PSP?
tau
visual field defect FND
tunnel vision
prosopagnosia brain location
bilateral occipito-temporal
Anton syndrome
cortical blindness with denial (anosagnosia)
confabulation
bilateral occipital (PCA) most common cause
aka anton babinksi
Gertmann syndrome
R-L disorientation
Agraphia
Acalculia
Finger agnosia
dominant parietal
Kluver-Bucy syndrome
hyperorality
hypersexuality
bulimia
simultagnosia
placidity
hypermetamorphosis
bilat temporals (esp hippocampus + amygdala)
what is naming apples as oranges?
semantic paraphrasia
PPA subtypes
semantic variant - impaired comprehension and word finding ++. FTLD-TDP
non-fluent/agrammatic - difficulty pronouncing, speech apraxia, poor inflection but good comprehension. FTLD-Tau
logopenic - impaired word repetition and impaired comprehension++. AD.
progressive decline, retains insight into difficulties
vascular
finger-nose ataxia lesion?
inf olivary nucleus
these ns go into cerebellar cortex
Alexia without agraphia
lesion: LEFT occipital or associated corpus callosum (splenium)
symptoms: unable to READ but able to communicate perfectly well and write down their thoughts
R sided homonymous hemianopia
PCA
graphesthesia
able to detect letters written onto skin
parietal lobe function
forced utilisation which lobe?
orbitofrontal
which part of WAIS-R is used for assessing cognitive decline in aging?
block design
hayling test?
test of inhibition
asked to complete sentences initially with words that fit and then that do not fit at all
seashore musical aptitude test
tests R temporal lobe for auditory attention
loss of verbal fluency lesion
Left frontal - Brocas
carotid bruit risks what symptom
amorosis fugax when clots go to opthalmic artery
how to differentiate psychogenic from organic coma?
caloric testing. put cold water into ear and visualise nystagmus
temporal order of memory is disturbed leading to out of context retrieval
confabulation. you see misordering and fusion of real memories to generate out of context memories
