Non-fluent aphasia in deaf user of Indian Sign Language
A case study
The current study describes aphasia in a deaf user of Indian Sign Language (ISL). One congenitally deaf adult with LHD was evaluated for signs of aphasia. The tools used were Aphasia Diagnostic Battery in Indian Sign Language (ADB in ISL), Magnetic Resonance Imaging (MRI) investigation, linguistic, and neurobehavioral profile. The results of all investigative procedures revealed signs and symptoms consistent with non-fluent aphasia specifically Broca’s aphasia. The data from ISL in brain damaged individual further emphasize the role of left hemisphere in sign language processing.
