Week 5: Language Disorders and Therapy Flashcards
Conduction aphasia
Inability to repeat words or phrases
Typically caused by damage to: supramarginal gyrus and arcuate fasciculus
Aphasics…
retain the underlying semantic and phonological representations of words,
but show impairments in accessing them
Aphasia incidence and prevalence
Incidence: 0.05% / year
Prevalence: 0.1-0.3%
Treatments
- Naming, word-to-picture mapping
- Linguistic tasks (e.g. sentence completion, semantic categorisation)
- Melodic intonation therapy (e.g. singing)
- rTMS
- tDCS
- Drugs (e.g. glutamate inhibitor memantine)
High frequency principle
Do as much therapy as possible
Focusing principle
Control of language use by constraints and guidance to avoid learned non-use (less you use something, the less likely you will be to use it in the future)
Behavioural relevance principle
Practice language in relevant action contexts
Therapy should utilise links between language and action areas (Hebb’s law)
e.g. naming vs requesting need different practice
ILAT
Intensive language-action therapy
Aims to use three principles
Language games (naming, requesting etc. around a table)
Seems to work, as long as it’s intensive
