Study Notes
Aphasia Recovery
- Lesion volume and integrity of perilesional areas are the strongest predictors of recovery from aphasia.
- Age, gender, handedness, stroke type, and aphasia type are not consistently demonstrated to influence recovery.
- Right hemisphere homologue region recruitment is important for recovery, particularly in the subacute phase.
- The interaction between brain-internal processes and behavioral intervention require further exploration.
Aphasia Impacts
- Aphasia has significant impacts on identity, overall health, relationships, and participation in society.
- People with aphasia are more likely to experience depression following stroke.
- Depression can negatively impact rehabilitation, exacerbating the effects of aphasia.
- People with aphasia are less likely to return to paid work, with only 28% returning compared to 45% of stroke survivors without aphasia.
- When they do return to work, it's often in a modified capacity or a different role.
- People with aphasia have fewer social contacts and reduced social networks, putting them at risk of isolation.
- Aphasia can transform relationships, introducing dependency not present before stroke.
- Aphasia has a significant negative impact on quality of life, exceeding the impact of cancer, dementia, and conditions affecting motor functioning.
Aphasia Aetiology and Comorbidity
- Haemorrhagic strokes are more likely to cause death than ischemic strokes.
- Those who survive haemorrhagic strokes tend to have better outcomes than survivors of ischemic strokes.
- Haemorrhages caused by AVMs often occur in younger, otherwise healthy individuals.
- The majority of people with aphasia experience milder symptoms.
- About 20% of people with aphasia are younger than 65.
- Motor impairments often accompany aphasia, especially with ischemic strokes causing expressive aphasia.
- Around 60% of stroke survivors experience aphasia, dysarthria, and/or dysphagia.
- Dysarthria and dysphagia are more common than aphasia and often co-occur.
- A small proportion (around 10%) experience all three conditions.
- 20-30% of people with communication impairments following stroke experience both aphasia and dysarthria.
- This is more common than aphasia alone or dysarthria alone.
- People with this profile often have significant aphasia and dysarthria.
Aphasia Recovery Continued
- Tissue re-profusion is the primary mechanism for recovery in the days and weeks following stroke onset.
- This is achieved through brain-internal processes and medical intervention.
- Spontaneous recovery, natural improvement without intervention, can persist for months after onset, with the greatest improvement around 1 month post-stroke.
Aphasia Prevalence and Incidence
- Around a third of stroke survivors will develop aphasia, potentially ranging from 25% to 40%.
- Aphasia is associated with increased mortality, higher rehabilitation costs, more frequent depression, and poorer functional outcomes.
- Aphasia severity typically decreases over time for most individuals.
- Aphasia is most severe at onset, following the stroke.
- 50-60% of people who initially present with aphasia will continue to experience it.
- Conversely, the remainder show substantial recovery.
- Some studies suggest that fewer than 25% experience complete recovery.
Aphasia
- Aphasia is an acquired language disorder caused by brain damage.
- It affects communication skills, impacting daily life.
- Not using "aphasic" as a noun to avoid stigma.
Prevalence & Incidence
- Approximately 1 in 3 people who experience a stroke develop aphasia.
- Aphasia is associated with increased mortality, higher rehabilitation costs, increased depression, and poorer functional outcomes.
- Aphasia severity typically decreases over time for most individuals.
- Around 50% of individuals with aphasia experience persistent symptoms.
- The remainder show significant improvement.
- It's estimated that around 80,000 individuals in Australia live with aphasia.
Aetiology (Causes)
- Brain damage in areas responsible for language processing (primarily left hemisphere).
- Stroke is the most common cause, disrupting blood supply to the brain.
- Other causes include traumatic brain injury, tumors, infections, and degenerative conditions.
- Hemorrhagic strokes are more fatal than ischemic strokes but have better outcomes if the individual survives.
- Motor impairments, including hemiplegia, hemiparesis, and dysarthria (speech motor control), are common in people with aphasia.
- Around 60% of individuals who experience a stroke present with aphasia, dysarthria, or dysphagia, with dysarthria and dysphagia being more prevalent than aphasia.
Recovery
- Primary mechanism of recovery is tissue reperfusion, through internal brain processes and medical intervention.
- Spontaneous recovery is most significant within the first month after the event.
- Factors influencing recovery include lesion volume, integrity of perilesional areas, age, gender, handedness, stroke type, and aphasia type.
- Recruitment of right hemisphere homologue regions might be important for recovery.
- The interaction between internal brain processes and behavioral intervention is not fully understood.
- While most improvement occurs in the early stages of recovery, even individuals living with chronic aphasia can improve language function.
Lifelong Effects
- Aphasia has a significant impact on mental health, with depression being a common concern.
- Individuals with aphasia are less likely to return to work, even if they do, their work capacity might be modified.
- Reduced social networks and contacts increase the risk of isolation.
- Aphasia has been found to have a larger negative impact on quality of life compared to other illnesses for those in long-term care.
Public Knowledge and Advocacy
- Public awareness of aphasia is low despite affecting a similar number of people as Parkinson's Disease.
- The lack of awareness is a barrier to improved services for individuals with aphasia.
Aphasia Syndromes
- Classified based on affected brain structures, reflecting the "classical connectionist model" (Wernicke).
- Syndromes are characterized by clusters of symptoms, often linked to lesion locations.
- This approach is commonly used but rarely questioned .
Critiques of Syndrome Approach to Differential Diagnostic of Aphasia
- Limited basis in theories of language processing.
- Does not differentiate between surface signs and symptoms with different causes.
- Inconsistent predictions of lesion location.
- Heterogeneity of presentation among individuals with the same syndrome classification.
- Doesn't offer clear guidance for intervention recommendations.
Current Speech Pathology Practice
- Employs the International Classification of Functioning, Disability and Health (ICF) framework, which highlights the relationship between individual and contextual factors surrounding a health condition.
- Different intervention approaches are used depending on the stage of recovery:
Acute Stage
- Focus on medical intervention.
- Assessment uses flexible strategies to diagnose and make preliminary judgments.
- Consultative activities for information sharing with individuals with aphasia, their families, and other healthcare professionals.
- Establishing robust communication for individuals with aphasia to interact with loved ones and healthcare providers.
- Direct aphasia intervention is often infrequent and complex.
Rehab Stage
- Transition from higher-level to lower-level inpatient care.
- Extensive testing and behavioral interventions target specific impairments.
- Emphasis on communicative efficacy with a focus on context-specific and practical skills.
- Team-based management to address multifaceted needs.
- Impairment-focused interventions to improve language processing.
- The rehab stage can be brief depending on severity, home support, and other factors.
Community Stage
- Shift from medical to community-oriented support.
- Reduced multidisciplinary care, primarily involving speech pathologists.
- Emphasis on self-support through accessible group activities, stroke recovery groups, and community resources.
- Individuals with aphasia seek services that offer hope for returning to preferred activities, increasing communication skills, understanding their condition, and supporting others.
Constraints and Influences
- Caseload of people with aphasia can be challenging to manage effectively.
Acute Setting
- Medical professionals face difficulty communicating with individuals with aphasia.
- Early psychosocial support is crucial for improving aphasia care in acute settings.
Rehab Setting
- Insufficient resources in hospitals for aphasia rehabilitation.
- High stress levels and potential resistance to testing among individuals with aphasia.
- Healthcare professionals sometimes feel unprepared to handle communication challenges with individuals with aphasia.
Community Setting
- The chronic and complex nature of aphasia is often poorly understood by healthcare systems.
- Limited access to NDIS support for individuals with aphasia.
- Individuals with aphasia are susceptible to isolation and disengagement.
- Creating a more accessible society for individuals with aphasia is essential.
- Speech pathologists haven’t been given sufficient tools and recognition
