ICF consists of two main parts

1. The functioning or disability of the person with the health condition 2. contextual factors that can affect the person to either improve or worsen the disability a.) impairments b.)communication activity limitations (convesation difficulties, diff using the phone, diff reading a newspaper) c.) participation restrictions (employment, relationship)

Experience-Dependent Plasticity

1. Use it or lose it 2. Use it and improve it 3. Specificiity 4. Repetition Matters (find different opportunities) 5. Intensity Matters 6. Time Matters-first 7-10 days, don't want to do too much. 7. Salience matters- importance of task to them 8. Age matters 9. Transference 10. Interfere

3 other domains besides impairment to be considered by afrom

1. greater participation in life activities 2. increased feelings of confidence 3. whether environmental barriers are reduced

5 steps of therapy

1. information gathering and sharing 2. collaborative goal setting 3. pretherapy assessment 4. therapy 5. reassessment

why discourse sampling

1. not examined by many aphasia batteries 2. inofmration involving activity and participation levels 3. Turn taking and topic management only assessed thrhough this

5 theories for restoring brain function

1. regression/resolution of diachisis 2. Restoration: reactivation of brain areas 3. recruitment: using brain areas that weren't being used 4. Retraining: certain brain areas perform additional/new functions 5. functional take over: undamaged areas take over functions

4 domains of AFROM

1.Environmental barriers or aids to communication 2. personal identify, attitudes and feelings 3. severity of aphasia (language impairments from aphasia) 4. participation in life situations (activities, roles and responsibilities, relationships i.e. job)

biopsychosocial approach to therapy (ICF)

therapy should take into account the biological impairment based factors and the psycholinguistic and cognitive processes of language and communication within the social context of the person with aphasia and his/her family

supplementary motor cortex

ability to initiate spontaneous utterances impaired by lesions in this area

aphasia is

an acquired neurogenic language impairment that can result in loss of a previous held ability to understand or produce speech and/or the ability to read or write

anosognosia

unaware of their condition

occiptal lobe

vision higher order analysis takes place in the visual association cortex (medial and lateral surfaces of occiptal lobe)

temporal lesion that extends posteriorly

visual connections are disrupted, more difficulty understanding written language and language in context but relatively less difficulty with isolated words

Extrapyramidal system

voluntary control of motor behavior

Frontal Lobes

voluntary control of movement throughout the body

hemiparesis

weakeness on one side of the body

informal assessment seeks to answer

what is the extent of problem where does behavior break down what helps the behavior what are the underlying mechanisms for the behavior

conduit d' approche

when repeated attempts come closer and closer to the target word

conduit d'ecart

when repeated attempts move further from the target word

anomic aphasia

word finding problems across tasks that require retrieval of specific substantive words -average phrase length is within normal ranges auditory comprehension and repetition are relatively or entirely intact -nonspecific phrases and circumlocution -paraphasias are rare "putting my words together. I can't seem to get 'em together. I can steem to get 'em together, that's what it is. The words that dno't appear in front of em yhou know. Like the words

primarily temporal lesion produces

word-deaf variant in which reading may be less affected may have difficulty understanding individual spoken words but can understand in context

conduction aphasia

anomia fluent output with normal average phrase length but may be interrupted by word finding pauses or attempts to self correct -auditory comprehension good repetition is worse -phonemic paraphasias very obvious (which they recognize and attempt to crrect" -circumlocitions may be produced -Reading aloud is impaired -deficits in naming and writing "I know the exact pert, part of it" i had a falve, a verve ah..it was being played, placed in the orta, the ...."

Broca's aphasia

anomia short phrase length good auditory comprehension poor ability to repeat words and phrases -agrammatism -phonemic paraphasias are common -articulation is effortful -automated verbal sequences are usually preserved -right hemiplegia -writing abilities are limited - can't read aloud, but can read andu nderstand. "April...twenty four. Europe. Mymother, my father, my husband. Go to airport. I hand ticket and fall down. At airport. I fall down.. and empulin...amalance...came."

types of informal assessment

attention, writing, reading, short term memory, social diagram

subcortical aphasias

borderline fluent aphasias -hypophonia semantic paraphasic -severe reduction of spontaneous speech

transcortical motor aphasia

characterized by impaired initiation of verbal output, anomia, short phrase length, good auditory comprehension and unlike Broca's aphasia good repetition relative to speech output- short utterances with grammatical words but incomplete sentences produced without articulatory effort. Inability to generate full sentences. -good reading comprehension "cabbie...cab driver...yes...for about seven years...ahtel worki, worked with hotels..bell captain mainly.. then sales."

embolism

clost that breaks free and travels around the body

Parietal lobes

damage to this area can produce a loss of sensation of touch and an impaired recognition of one's own body (asomatognosia) and a loss of the ability to appreciate spatial concepts

a-from

diagrammatic representation of the parts of the ICF that are relevant to aphasia- therapy can intervene in any component of this process Direct therapy can achieve this by : improving language function, everyday communication activities or social participation -can also be helped by optimizing contextual factors

Lesions for transcortical motor aphasia caused by

disruption of blood flow in the anterior cerebral artery or in the anterior most branches of the middle cerebral artery -infarction in the border zone territory between the anterior and middle cerebral arteries is the most common cause

Temporal lobes

hearing and analysis of auditory signals -posteriorportion of the superior temporal gyrus (Wernicke's) is auditory association areas- analyzes auditory stimuli to the point of comprhenesion -medial temporal lobes- important for memory

2 types of neuroplasticiity

Transcortical Sensory aphasia caused by

posterior lesions in the border zone between the middle and posterior cerebral arteries, in parieto-occiptal regions sparing Wernicke's area' -frequently associated with bilateral lesions in the border-zone territory (often seen with alzheimers)

comprehensive exam should include

procdures for determing the integrity of other cognitive skills (attention, memory and executive functions) discourse sampling

General Aphasia Treatment Approaches: 1. Impairment level

process oriented-medical rehab model -stimulation approach -drills, such as point to, answering questions, following directions, confrontation naming -CIAT, MIT,TAP,VAT -"clinician centered" with person with aphasia being dependent, passive patient -treatment focuses on the impairment

paraphasia
