Chapter 7 Flashcards
Describes the types of communication deficits seen in people who have sustained damage to the brain in one way or another.
Neurological Impairments
Related to linguistic programming, speech motor programming, and the production of expressive speech and language.
Broca’s Area
Primarily responsbile for the comprehension of speech and language and the formulation of language concepts.
Wernicke’s Area
Language that is formulated in Wernicke’s Area is transmitted (via the arcuate fasciculus) to…
Broca’s Area for speech to be programmed and transmitted to the muscles for speech.
The loss of the ability to comprehend or formulate language typically associated with neurological damage.
Aphasia
A disorder that results from damage to the parts of the brain that contain language
Aphasia
Causes problems with any or all of the following: speaking, listening, reading, and writing
Aphasia
What causes damage to the brain that results in Aphasia?
Typically caused by a stroke (Cerebrovascular Accident CVA)
What causes strokes?
- blockage in a blood vessel supplying blood to brain (ischemic)
- Or bleeding in or around the brain (hemorrhagic)
Says, “A disturbance of one or more aspects of language comprehension, one or more aspects of language form and expression. The disturbance is caused by newly acquired disease of the CNS.”
Damasio (1981)
Types of Strokes (CVA)
- Ischemic
2. Hemorrhagic
Blockage in the artery that supplies blood (oxygen) to the brain.
Ischemic Stroke
“Gradual blockage”
Thrombosis
“Clot gets lodged in artery causing blockage”
Embolism
A bleed in the brain caused by an aneurysm
Hemorrhagic Stroke
A bubble in the artery. Over time it gets weak and bursts
Aneurysm
Difficult with retrieving and producing words
Anomia
Sound and word substitutions that are often found in the speech of aphasic patients whose speech and language is fluent
Paraphasias
Words made up by patients with aphasia. They use them as though everyone understands them
Neologisms
Using normal intonation, prosody, and fluent speech and language while stringing together a series of meaningless words that don’t make sense to the listener.
Jargon
Deficit where articles, conjunctions, and grammatical morphemes might be left out. Effortful; short sentences tend to leave in nouns and/or verbs
Agrammatism
Leaving out most nouns and verbs, leaving in only non-content words.
Paragrammatism
Unintentional repetition of a word, sound or movement.
Perseveration
- Varies in severity
- Depends on extend and location of damage
- Damage associated with Wernicke’s Area and surrounding tissue
- Perhaps like hearing another language
Deficits of Comprehension associated with Aphasia
May be able to understand simple conversation, but not complex
Aphasia
May be able to follow simple commands, but nothing more
Aphasia
Verbal anosia- “pure word deafness”- unable to comprehend any verbal language
Aphasia
Difficulty identifying sensory information.
Agnosias
Client is able to perceive the sensation, but unable to interpret what is it
Agnosias
Can be evident in all senses: visual, tactile, auditory, taste, and smell
Agnosias
Able to read words, but can’t explain, doesn’t know what they have read.
Visual Agnosias
Patient can read fluently, but has no idea what the word means
Visual Agnosias
