Summary
Aphasic patients post-stroke frequently exhibit sensorineural hearing loss. Their comprehension deficits challenge traditional speech audiometry, necessitating adapted evaluation methods for accurate audiological findings.
Area of Science:
- Audiology
- Neurology
- Speech-Language Pathology
Background:
- Cerebrovascular accidents (CVAs), or strokes, can lead to aphasia, affecting communication abilities.
- Auditory processing and hearing function may be impacted following a stroke.
Purpose of the Study:
- To characterize the audiological findings in patients diagnosed with aphasia subsequent to a cerebrovascular accident.
- To identify hearing loss prevalence and specific audiological test results in this patient group.
Main Methods:
- A cross-sectional study involving 43 aphasic patients (27 male, mean age 54.48) evaluated between March 2011 and August 2012.
- Standard audiological assessments including pure tone audiometry, speech audiometry, immittance measures, and otoacoustic emissions were conducted.
Main Results:
- Sensorineural hearing loss was a significant finding, present in 78.6% of the participants.
- Challenges were encountered in obtaining speech audiometry results (Speech Recognition Threshold, Word Recognition Score) due to patients' comprehension and oral production difficulties.
- Hearing loss is a common comorbidity in aphasic individuals post-stroke.
Conclusions:
- Aphasia resulting from stroke complicates conventional speech audiometry due to impaired comprehension and/or oral emission.
- Modified audiological evaluation procedures are required to accurately assess hearing in aphasic patients.
- These findings highlight the importance of comprehensive audiological assessment in stroke survivors with aphasia.
