What are Adult language disorders and how do they differ from developmental language disorders?
Adult language disorders are developed after language is already fully developed! Unlike DLD in which are formed much earlier in life, prior to the full formation of language.
What are the causes of neurogenic language disorders?
Cerebrovascular Accident
TBI
Tumors or neoplasms
Infections
Dementia
Aphasia what is it?
Language disorder that can affect all aspects of language 5 big pillars, phonology, morphology, syntax, semantics, and pragmatics
due to brain damage, left hemisphere, or a stroke
What are the aphasia classifications
naming
fluency
auditory comprehension
repetition
*Specific tasks can mean specific things **
what are the steps to naming
- recognizing what the object is
- retrieving the correct word label
- develop phonological encoding of the word
- plan speech movements to produce word
what is a hallmark of aphasia
naming
what are neologisms
new, nonsense words
verbal/ semantic paraphasia
word that is semantically related to the intended word (dog for cat)
literal paraphasia
transposing/substituting sounds in a word (Ley for Key)
circumlocution
talk around the word that they need, or are trying to say
fluency
effort less production of speech that flows rhythmically with good prosody. doesnt have to be intelligble
non fluent
not complete sentances, slow, halting bad prosody.
what is considered in fluency
rate and intonation
how do we test comprehension
- single words, ask them to identify objects in pictures,
- 1 step directions, point to objects
- multi step directions
- yes/ no questions
- wh questions
repetition
ability to repeat things back, assess pathway, arcuate fasciculus, between broca (speech) and wernickes area (processing speech)
what are non fluent aphasias
brocas, transcortical motor aphasia, global aphasia, mixed transcortical aphasia
characteristics of Broca’s aphasia
non fluent, but good comprehension, poor repetition,. can follow commands, and name objects.
damage to brocas area in the frontal lobe of the left hemisphere
characteristics of transcortical motor aphasia,
non fluent, but good comprehension, good repetition
damage to watershed area in frontal lobe
characteristics of global aphasia
non fluent, poor comprehension, poor repetition
damage is extensive, to frontal lobe, brocas area to parietal lobe, the wernickes area.
damage to the parasylveion region
characteristics of mixed transcortical aphasia
damage to the watershed frontal lobe, and temporal lobes,
non fluent, poor comprehension, some repetition, very preserved.
what are fluent aphasias?
wernickes Aphasia, conduction aphasia, transcortical sensory aphasia
characteristics of Wernickes Aphasia
fluent, but poor comprehension, and poor repetition
neologisms - non exsistent words
paraphasias - incorrectly produces words and syllables
not aware that they do not make sense
damage to wernickes area in the upper and posterior part of the temporal lobe
characteristics of transcortical sensory aphasia
fluent, with poor comprehension, but good repetition
damage to the watershed temporal lobe
characteristics of conduction aphasia
fluent, with good comprehension, but very poor repetition
BROCAS AND WERNICKE ARE INTACT THE ARCUATE FASCICULUS IS NOT, WHAT CONNECTS THESE PARTS.
