Study Notes
Language vs. Communication
- Language, combined with sophisticated communication, distinguishes humans from animals.
- Humans utilize language while animals communicate without a structured language system.
Language vs. Speech
- Speech involves verbal communication aspects such as articulation, voice, and fluency, relying on neuromuscular programming.
- Language encompasses social rules for expression, covering semantics, morphology, syntax, grammar, and pragmatic considerations.
Basics of the Nervous System
- Central Nervous System (CNS): Comprises the brain, spinal cord, and brainstem, responsible for language and cognitive functions.
- Peripheral Nervous System (PNS): Includes cranial and spinal nerves, facilitating motor and sensory functions, and controlling autonomic functions.
- CNS is protected by a bony shell, meninges, and cerebrospinal fluid.
- Neurons consist of dendrites, a cell body, an axon, terminal endings, and synapses; glial cells support and provide myelination.
- Gray matter consists of neuron cell bodies and dendrites, while white matter contains myelinated axons.
Divisions of the Central Nervous System
- The Left Hemisphere: Primarily involved in language production and comprehension.
- The Right Hemisphere: Involved in spatial functions, melody, and intonation.
- Major brain lobes: Frontal, Parietal, Temporal, and Occipital, each with specific structural and functional roles.
Types of Stroke (CVA)
- Ischemic strokes occur from artery blockages and include transient ischemic attacks (TIAs), thrombosis, embolism, and lacunar strokes.
- Hemorrhagic strokes divide into intracerebral (bleeding within cranial tissue) and extracerebral (bleeding in the meningeal tissue).
- Treatment focuses on preserving penumbra tissue and may include carotid endarterectomy, stenting, clot retrieval, and tPA administration.
Perisylvian Language Areas
- Broca's Area (BA 44 and 45) in the frontal lobe handles language production, syntax, and morphology.
- Functional MRI (fMRI) assesses brain functionality in response to tasks without the use of radioactive tracers.
Statistics of Neural Injury
- Approximately 795,000 strokes occur annually in the U.S., costing $34 billion yearly.
- Stroke is a leading cause of long-term disability; prompt hospital arrival within three hours reduces disability risks.
- About 2.5 million people sustain traumatic brain injuries (TBI) each year, with children and older adults at higher risk.
- In 2013, 5 million individuals in the U.S. were living with Alzheimer's, a major cause of death.
Social Impact and Recovery
- Recovery and coping are influenced by individual and social networks, including family roles, financial stability, and social integration.
- Rehabilitation leverages neuroplasticity, focusing on long-term reorganization of brain functions following injury through therapy.
Illness Experience Stages
- Stage 1: Uncertainty regarding illness, overwhelming family observations.
- Stage 2: Family assumes responsibility while the patient distracts themselves.
- Stage 3: Regaining self, goal setting for rehabilitation.
- Stage 4: Attaining mastery and closure, family acknowledges new roles.
Comorbidity of Mood Disorders
- Recognizing and treating depression can significantly enhance the quality of life for patients and their families.
- Depression negatively affects well-being and is common with brain injuries; active treatment approaches are preferred.
Chronicity of Illness
- Chronicity refers to the prolonged duration of impairment, with various emotional reactions over time, including shock, denial, and adaptation.
Adaptation and Coping
- Adaptation abilities are influenced by individual factors (age, cognitive ability) and external factors (family, culture).
Quality of Life Assessment
- Quality of life evaluations consider physical health, psychological health, independence, social relationships, and one's connection to the environment.
Understandings of Aphasia
- Aphasia is an acquired neurogenic language disorder resulting from left hemisphere damage; it does not align with sensory, motor, or cognitive deficits.
- Crossed aphasia occurs when impairments arise from the nondominant hemisphere.
Theories and Models of Aphasia
- Classical associative connectionist paradigm classifies aphasia types; central language areas include Broca's and Wernicke's areas.
- Cognitive neuropsychological models use single-word processing studies for hypothesis testing of breakdowns in language processing.
Signs and Symptoms of Aphasia
- Varied paraphasias include verbal semantic errors, literal/phonemic errors, neologisms, and anomia (naming impairment).
- Agrammatism involves reduced function words and reliance on content words, often co-occurring with comprehension impairments.
Classification Systems of Aphasia
- The Western Aphasia Battery (WAB) reliably classifies individuals into categories based on fluency, comprehension, and naming skills, though it may force categorization.
Pros and Cons of Classification
- Classification aids in identifying patterns in aphasia but may oversimplify individual variations.
- Individuals may have unique aphasia patterns that do not fit neatly into established categories.
Best Practices for Intervention
- Develop intervention goals based on each individual's signs and symptoms and consider co-occurring impairments that may impact recovery efforts.
