Term
disorders of awareness - confusional state:
Definition
the inability to maintain coherent line of thought.
Term
inattention
Definition
right unilateral inattention might be found
Term
inintention
Definition
motor neglect
Term
motor disorders
Definition
hemiparesis, dysarthria, extraocular motor paresis, pseudobulbar palsy, apraxia
Term
hemiparesis - usually associated w/:
Definition
broca's aphasia - defect in right motor body... sometimes it's severe soemtimes it's mild - affects the hand and face (less severe: leg), damage of UMN so it's spastic. (thus, usually spastic dysarthria)
Term
hemiparesis in conduction:
Definition
common to find initial hemiparesis but it tends to go away or at least decreases in severity
Term
hemiparesis in extrasylvian motor type II (aphasia of supplementary motor area)
Definition
right leg hemiparesis is found and unusual gait
Term
wernicke's or extrasylvian motor defects
Definition
none really noted... really depends on the extension of the pathology
Term
extrasylvian motor aphasia I don't present with hemiparesis but may present with
Definition
deficits in controlling the eye movements and defects in visual scanning
Term
dysarthria is:
Definition
a neurologic speech disorder that is charactcterized by slow, weak, imprecise and/or uncoordinated movements of speech musculature.
Term
3 movement systems
Definition
pyramidal, basal ganglia, cerebellum
Term
damage to pyramidal:
Definition
UMN - spasticity
LMN - flacidity
Term
damage to basal ganglia:
Definition
hypo/hyperkinesia
Term
damage to cerebellum
Definition
ataxia
Term
thus, there are # many types of dysarthria
Definition
5 - spastic, flaccid, hypo/hyperkinetic, ataxia
Term
extraocular motor palsies
Definition
brain damage involving frontal eye field (brodmann 8) will result in in impairments in eye movement, especially upon request. common in extrasylvian motor aphasia I
Term
pseudobulbar palsy
Definition
is the paralysis that results from bilateral UMN lesions of the pyramidal tract (same kind of paralysis as in bulbar palsy)
Term
what % of aphasics present ideomotor apraxia?
Definition
40%
Term
conduction aphasia is assocaited with
Definition
ideomotor aphasia
Term
if you find ideomotor apraxia in wernicke's aphasia, this suggests...
Definition
a lesion that extends to the parietal lobe
Term
pt with broca's aphasia present with a __________ apraxia.
Definition
sympathetic. this means that the apraxia is only in the left lobe...
Term
apraxia of speech
Definition
is an impairment in the planning and programming of sequences of movements required for speech production (that and agrammatismo underlie broca's)
Term
in apraxia of speech, errors are:
Definition
inconsistent.
Term
in apraxia, which type of lang is best?
Definition
automatic language
Term
aprax of speech also coocurs with
Definition
buccofacial or oral apraxia
Term
2 types of verbal apraxia. 1st type is PRE ROLANDIC this corresponds to
Definition
"apraxia of speech" found in Broca's aphasia
Term
the 2nd type of verbal apraxia is POST ROLANDIC is associated with
Definition
conduction aphasia (it has been suggested that verbal apraxia and conduction aphasia are the same disorder.)
Term
SENSORY DISORDERS - 2 types
Definition
somatosensory and visual
Term
somatosensory defects
Definition
are more evident in conduction aphasia bc of the parietal damage. can be found in a lesser degree in broca's and wernicke's depending on the extent of the lesion
Term
in conduction aphasia it is common to find:
Definition
hypoesthesia, difficulties in two point discrimination, and tactile extinction
Term
right homonymous hemianopia is almost invariable in:
Definition
alexia without agraphia
Term
in wernicke's aphasia, it is common to find (think visual)
Definition
a right upper quadrantopsia
Term
extrasylvian sensory
Definition
occasionally some visual field defects
Term
parietal aphasia sometimes has (visual)
Definition
inferior quadrantanopsia if the damage extends deeply in the brain
Term
DISORDERS OF COGNITIVE FUNCTION
Definition
Term
amnesia
Definition
difficulties in memorizing verbal info, a sub-type of wernicke's has been interpreted as specific verbal amnesia (anterograde and retrograde)
Term
a broader amnesia can be found if aphasia damage extends to:
Definition
prefrontal areas, hippocampus, etc.
Term
3 types of agnosia
Definition
visual, auditory, somatic
Term
visual agnosia
Definition
associated with aphasia - difficulties in revisualization of objects - a sort of temporal/occipital detatchment
Term
visual agnosia can be assocaited with..
Definition
alexia. alexia without agraphia (agnosic agraphia)aka achromatopsia
Term
auditory agnosia:
Definition
aka WORD DEAFNESS. also appears in acoustic-agnosic aphasia - wernicke's aphasia type 1 (the aphasia part also includes stuff such as paraphasias).
Term
Gerstmann's syndrome
Definition
finger agnosia, right-left disorientation, acalculia and agraphia.
Term
acalculia
Definition
primary (anarithmetia) and secondary
Term
primary acalculia
Definition
difficult to find, left posterior parietal damage. conduction aphasia is most frequently associated with anarithmetia
Term
aphasic acalculia
Definition
calculation difficulties correlated with language defects
Term
alexic acalculia
Definition
can be correlated with reading difficulties. alexia for numbers
Term
agraphic acalculia
Definition
calculation errors can appear as an inability to write quantities. specific difficulties will be correlated with the specific type of agraphia
Term
frontal acalculia
Definition
pts can count, compare quantities, and perform simple arithmetic operations if they can work with a pencil and paper. can't do things in their head.. can be found in extrasylvian motor I
Term
gerstmann syndrome
Definition
finger agnosia, acalculia, agraphia, right left disorientation - aka angular gyrus syndrome - no supposed aphasia - but there is debate of whether or not to replace agraphia with semantic aphasia or simply add it as a descriptor.
Term
dementia
Definition
progressive decline in cognition due to damage or disease in the brain- (degeneritive conition, multiple infarcts, etc.) beyond what is expected in normal aging. Areas affected: MEMORY, langauge, attention and executive function
Term
gerstmann syndrome
Definition
finger agnosia, acalculia, agraphia, right left disorientation - aka angular gyrus syndrome - no supposed aphasia - but there is debate of whether or not to replace agraphia with semantic aphasia or simply add it as a descriptor.
Term
alzheimer's (progression)
Definition
initially dementia, then extra sylvian sensory, and semi/mutism at the end - 2/3 of total # of dementia cases
Term
vascular dementia
Definition
2nd most common dementia - produces focal or diffuse effects, causes cognitive decline.
Term
progressive aphasia
Definition
subtype of alzheimer's
