Study Notes
Aphasia and Cognitive Disorders
- Acquired neurogenic language disorders (NLDs) are defined
- Four broad categories of NLDs are listed: aphasia, right hemisphere damage, traumatic brain injury, and dementia
- Aphasia: language impairments affecting expressing, understanding, reading, and writing
- Right hemisphere damage: memory impairments, attention problems, impulsivity issues, and visual dysfunction
- Traumatic brain injury: cognitive-communication impairment resulting from brain damage
- Dementia: loss of cognitive and linguistic abilities due to progressive brain disease
- Aphasia is not a developmental disorder; it's acquired following neurological injury
- Language problems are not necessarily linked to motor problems
- People with aphasia often have intact psychosocial abilities, except in some cases
- Aphasia is an impairment in comprehension and formulating language due to recent/acquired central nervous system damage (Rosenbek et al, 1989)
- Literal meaning of aphasia is "without language"
- It's a disturbance in the adult language system after language has been established/learned
- It results from neurological injury to the language-dominant hemisphere of the brain, causing receptive and/or expressive problems with spoken or written language.
- CVA (Cerebral Vascular Accidents) - ischemic (occlusive mechanisms), hemorrhagic, cerebral aneurysm, arteriovenous malformation
- Neoplasms (brain tumors)
- TBI (traumatic brain injury)
- Medications
Classification of Aphasia
- Classification of aphasia syndromes (taxonomy) is agreed upon, but there's disagreement on the best approach
- Classification often considers the cause, site of lesion, language characteristics, and dichotomous deficits, such as motor/sensory, receptive/expressive, anterior/posterior involvement, and fluent/non-fluent categories
- Boston System: a framework for characteristics of language impairment (fluency, auditory comprehension, naming, repetition, reading, writing)
- Specific aphasia types (based on the Boston System) include Broca's, Wernicke's, conduction, global, transcortical motor, transcortical sensory, anomic, and subcortical aphasias
Fluency
- Fluent aphasia: smooth, uninterrupted speech flow, usually resulting from posterior brain damage in the temporal/parietal regions in the brain
- Non-fluent aphasia: reduced phrase length, hesitations, slow/labored speech production, grammatical impairments, and variation in pitch/stress; often linked to anterior brain damage (frontal lobe).
Auditory Comprehension
- Auditory comprehension involves understanding spoken language
- It's a complex process encompassing segmenting sounds, understanding words within a sentence, retaining the message in memory, and formulating responses
- Factors influencing comprehension include the amount of information, frequency of word usage, personal relevance of the information, and part of speech
Repetition
- Repetition involves accurately reproducing verbal stimuli heard
- The process involves receiving, processing, and conveying the stimulus to brain regions for formulating and planning the motor sequence for speech
- Good connecting pathways between Wernicke's and Broca's areas are essential for efficient repetition
Naming
- Naming is the ability to retrieve and produce a target word; it's a complex process entailing recognizing the object, retrieving the semantic label, forming the phonological form of the label, and programming speech movements.
- Anomia is a disturbance in the ability to name; it's a pervasive and persistent deficit.
- Paraphasias are errors in naming, including phonemic (substitution/transposition of a phoneme) and semantic errors (similar/related words used instead).
Reading and Writing
- Fluency in writing typically mirrors fluency in spoken language
- Individuals with auditory comprehension problems also struggle with comprehending written information
- Written language impairments often parallel spoken language deficits
Review of Neuroanatomy
- This section is focused on the anatomy
- Critical brain regions in aphasia are frequently mentioned
- There may be another document or video explaining them
Assessment Characteristics
- A variety of detailed characteristics of specific aphasia types, including Broca's, Wernicke's, conduction, global, transcortical motor, transcortical sensory, anomic, and subcortical, are provided, with factors explaining their characteristics
- Information on areas of damage, effects on language functions, fluency (smoothness/interrupted flow of speech), auditory/receptive/expressive comprehension, naming difficulties, articulation errors, circumlocutions, repetition, reading, and writing abilities.
Course Assessments
- A detailed schedule of class, quizzes, case studies, presentations, a midterm exam, and a final exam/project are provided
