Aphasia - etiology

Question 1

Anderson, Olsen, Dehlendorff, & Kammersgaard, 2009

Answer 1

• Overall, strokes are more severe in hemorrhagic compared to ischemic strokes: higher risk of mortality within the first 3 months, even after adjusting for age, sex, initial stroke severity, and cardiovascular risk factors . No specific mention of language

Question 2

Paolucci et al 2003

Answer 2

• When baseline factors including neurological severity, functional severity, age, sex are matching, individuals with hemorrhagic stroke appear to have better functional outcomes than people with ischemic strokes. This is presumably due to better neurological recovery with hemorrhagic stroke – as the hematoma (which caused brain pressure) resolves, neurological functions recover and functional status improves. No specific mention on language

Question 3

Coelho et al (2010)

Answer 3

• PHI, not with aphasia
• Result in discourse deficits that are not due to aphasia, aging, or level of education
• Any type of TBI at risk for discourse impairments that don’t go away with time and have a significant impact on social integration and quality of life
