Abstract
PURPOSE
Individuals with non-traumatic subarachnoid haemorrhage (SAH) are often excluded from studies of stroke populations due to differing pathophysiology and treatment pathways. Thus, aphasia presentation in the non-traumatic SAH population is potentially under-represented within existing research evidence.
MATERIALS AND METHODS
Five databases were systematically searched with terms related to "aphasia" and "subarachnoid haemorrhage." Studies were included if aphasia was attributed to non-traumatic SAH or its associated complications, and where at least one language assessment measure used determined the presence or absence of aphasia. Study quality was evaluated using the Mixed Methods Appraisal Tool (MMAT).
RESULTS
Following deduplication, 2726 articles were identified for title and abstract screening. Full text screening for 162 articles occurred, with 18 articles selected for inclusion. Aphasia incidence ranged from 5 to 24%, and was influenced by assessment measure, timing of assessment, subgroup studied, and classifications of aphasia. Many studies excluded participants with poorer clinical outcome, intracerebral complications, or severe aphasia. Few studies used comprehensive language assessment measures to examine across language domains.
CONCLUSIONS
Aphasia presentation is highly heterogenous following non-traumatic SAH. Future research using comprehensive language assessments at multiple time points post onset is required to better understand aphasia presentation and management needs for this population.
