R hemisphere brain damage
related mostly to perceptual and attentional deficits
Tx of aphasia concerned with
verbal expression
aud comp
reading, writing, nonverbal modes of communication
ischemic strokes
caused by blocked or interrupted blood supply to brain
thrombosis or embolism
thrombus
collection of blood material that blocks the flow of blood
hermorrhagic strokes
bleeding in brain due to ruptured blood vessels.
more than X % of stroke survivors have aphasia
50%
% of strokes are ischemic
87%
nonfluent aphasias (GMBTm)
limited agrammatic effortful halting slow speech
impaired prosody
Broca’s supplied by
posterior inferior frontal gyrus of left hemisphere
supplied by upper MCA
Transcortico motor TMA impacted areas
nonfluent
anterior cerebral artery and anterior branch of MCA
TMA patients have seriously impaired
writing skills are seriously impaired in these pts
distinguishing feat in TMA patients
intact rep. skills can repeat long complex sentences without errors
Mixed transcortico MTA lesions located in X
nonfluent
lesions in watershed regions
distinguish feat. of Mixed transcortico
severe echolalia- parrotlike of what is heard
and mostly UNimpaired auto. speech like numbers
global- lesions in X areas
MOST SEVERE NONFLUENT APHASIA
lesions in all lagnuage areas- perisylvian
FLUENT APHASIAS (WTsCA)
intact fluency and meaningless speech
speech is relatively easily initiated and well articulated in these aphasias
in fluent aphasia (WTsCA)
