Agraphia Flashcards
what are the 2 types of agraphias
-central
-peripheral
what are the types of central agraphias
- phonological
-deep
-lexical
-surface
what are types of peripheral agraphias
-allographic disorders
-apraxic agraphia
define phonological agraphia
difficulties in sounding out words with relative preservation of ability to write real words
central agraphias are associated with damage to
perisylvian lang areas (broca’s area, wernickes, area, and supramarginal gyrus)
deficits in lexical semantic or non-lexical spelling routes, grapheme buffer
central agraphia
T/F peripheral agraphia is lang based
FALSE
more about physical writing
T/F central agraphia is lang based
true
which agraphia has deficits in both phonological and lexical skills, more deficits for abstract nouns, grammatical functor words
deep agraphria
deep agraphia is more severe than
phonological agraphia
which agraphia has difficulties in visaulizing spelling of words with relative preservation of sounding them out
lexical agraphia
which agraphia has more erros for uncommon words, grammar and sentence writing tend to be preserved, seen in lesions of left extrasylvian temporo-parietal regions
lexical agraphia
which agraphia is a written counterpart of surface dyslexia
surface agraphia
is central or peripheral agraphia characterized by losss of orthographic rules and spelling is performed based on phonological knowledge
central agraphia
phonetic spelling errors may be common in
central agraphia
allographic disorders is associated with damage to
left parieto-occipital region
people with allographic disorders may have inability to
active or select appropriate letter shapes with relatively intact oral spelling
clients with allographic disorder have difficulties with
writing upper or lowercase letters or they may produce case-mixing errors
T/F client with allographic disorders may produce well-formed letter substitution errors with physical similarity to the target sounds
TRUE
A PERIPHERAL diosrder due to damage to graphic motor program
apraxic agraphia
characterized by poor letter formation that cannot be explained by sensorimotor impairment or damage to basal ganglia or cerebellum
apraxic agraphia
T/F oral spelling will not be preserved in apraxic agraphia
FALSE
it can be preserved
what are typical errors of apraxic agraphia
spatial distortion, illegible handwriting
list agraphia assessments
-graphomotor tasks
(tasks involving writing with a pen/pencil): check about errors, letter formation, self-correction attempts
-Linguistic writing tasks: picture description, language tasks
-Automatic writing: signing name, writing name and address
-Propositional writing: writing about a topic, picture description
-Written confrontation naming: writing name of an object/picture when represented
-Writing to dictation
-Narrative writing
-Functional writing: check writing, emails, text messages, notes
treatment for central agraphias
-retraining of lexical-semantic processes
-Retraining of nonlexical spelling processes
-Lindamood Phoneme Sequencing (LiPS) program
-Copy and Recall Treatment
-Tactile-Kinesthetic approach
-Semantic Feature analysis
treatment for peripheral agraphia and apraxic agraphia
-Focus on retraining of graphic motor programs
-Focus on retraining ability to hold a pen/pencil to write effectively, letter formation, ability to draw, copy and write figures, numbers, and other symbols
