Study Notes
Acquired Neurogenic Language/Cognitive Disorders
- Four categories exist: aphasia, right hemisphere damage, traumatic brain injury, and dementia.
Aphasia
- Impairment in expressing, understanding, reading, or writing oral and written language.
Right Hemisphere Damage
- Memory impairment, attention and impulsivity problems, and visual dysfunction.
Traumatic Brain Injury
- Cognitive-communication impairment associated with brain damage.
Dementia
- Loss of linguistic and cognitive ability due to a progressive brain disease.
Additional Considerations
- Not a developmental disorder; acquired following neurological injury.
- Language-based, not motor-based, although the two can coexist.
- People with aphasia usually have intact psychosocial skills (though not always)
- Do not confuse language deficits for psychological disturbance.
Definition of Aphasia
- Impairment due to acquired and recent damage to the central nervous system in the ability to comprehend and formulate language (Rosenbek et al, 1989).
- Literally means "without language."
- A disturbance in the adult language system after the language has been established or learned.
- Results from neurological injury to the language-dominant hemisphere of the brain.
- Includes disturbances of receptive and/or expressive abilities for both spoken and/or written language.
What Causes Aphasia?
-
CVA (Cerebral Vascular Accidents):
- Ischemic (occlusive mechanisms)
- Hemorrhagic
- Cerebral aneurysm
- Arteriovenous malformation
- Neoplasms in the brain (tumors)
- TBI (Traumatic Brain Injury)
- Medications
How to Classify Aphasia
- Agreement to classify aphasia syndromes (taxonomy).
- Disagreement on how to classify aphasia.
- Cause (site of lesion).
- Language characteristics (dichotomous based on deficits: motor/sensory, receptive/expressive, anterior/posterior, fluent/non-fluent).
- Boston System (characteristics of language impairment).
Boston System Characteristics of Language Impairment
- Fluency
- Auditory Comprehension
- Naming
- Repetition
- Reading
- Writing
Boston System Types of Language Impairment
- Broca's
- Wernicke's
- Conduction
- Global
- Transcortical Motor Aphasia
- Transcortical Sensory Aphasia
- Anomic
- Subcortical
Fluency
- Fluent Aphasia: Spontaneous speech flow with adequate phrase length; typically posterior brain damage (temporal/parietal regions).
- Non-Fluent Aphasia: Diminished phrase length, hesitations, slowed or labored speech production, grammatical/pitch & stress variation impairments; typically anterior brain damage (frontal lobe).
Auditory Comprehension
- Ability to understand spoken language.
- Complex process involving phonemes, understanding the meaning of within words in a sentence, retaining the message, processing, and formulating a response.
- Influenced by: amount of information, frequency of word usage, personal relevance of information, and part of speech.
Repetition
- Ability to accurately reproduce verbal stimuli one hears.
- Incoming stimuli are received and processed.
- The information is conveyed to regions of the brain for formulating and planning the motor sequence for speech.
- Articulating to reproduce the initial stimulus requires good connecting pathways between Wernicke's and Broca's areas.
- Wernicke's area is crucial for processing and understanding auditory information.
- Broca's area is important for programming & movements for speech production.
Naming
- Ability to retrieve and produce a target word.
- Recognizing the object, retrieving the semantic label for it, developing the phonological form of the label, programming the speech movements to say the word.
- Anomia = disturbance in the ability to name; most pervasive and persistent deficit.
- Paraphasia = substitution or transposition of the targeted phoneme.
- Semantic error = error related to or in the same category as the word, but incorrect.
Reading and Writing
- Written language disturbances typically parallel spoken language impairments.
- Non-fluent speakers will also be non-fluent in writing and reading.
- Individuals with auditory comprehension problems will also have difficulty comprehending written information.

- Not included in the provided content.
What are the characteristics of each type of aphasia?
- Detailed characteristics (location of damage, fluency, agrammatism, naming deficits, paraphasias, repetition issues, comprehension issues, reading issues, writing issues) of each type of aphasia, including:
- Broca's
- Transcortical Motor
- Global
- Wernicke's
- Transcortical Sensory
- Conduction
- Anomic
