Attention deficits after incident stroke in the acute period: frequency across types of attention and relationships to patient characteristics and functional outcomes

Attention deficits after incident stroke in the acute period: frequency across types of attention and relationships to patient characteristics and functional outcomes

Topics in Stroke Rehabilitation 17(6): 463-476

Attention deficits are common post stroke and result in poorer functional outcomes. This study examined the frequency of attention deficits after incident stroke and their correlates. Attention of 94 stroke survivors was assessed using the Bells test, Trails Making Test A/B, 2.4- and 2.0-second trials of the Paced Auditory Serial Addition Test (PASAT), and Integrated Auditory Visual Continuous Performance Test (IVA-CPT) within 3 weeks post stroke. Wider functioning was assessed using the Medical Short Form-36 (SF-36) Physical and Mental Component Summary scores (PCS and MCS), London Handicap Scale, Modified Rankin Scale, General Health Questionnaire-28, and Cognitive Failures Questionnaire (CFQ). Most participants were impaired or very impaired on the IVA-CPT (z scores ≯ 3 SDs below normative mean) but not other attention measures. Functional independence and cognitive screening test (Mini-Mental State Examination) performance were significantly related to IVA-CPT, Trails A/B, and Bells tests but not PASAT. Better performance across the Bells test was related to better SF-36 PCS, whereas Trails A and the PASAT were related to SF-36 MCS. Better CFQ naming was related to Trails B, whereas worse CFQ memory was related to better PASAT performance. Attention deficits are common post stroke, though frequency varies widely across the forms of attention assessed, with tests of neglect and speeded attention tasks being linked to quality of life. This variability of performance and linking to wider outcomes suggests the need for comprehensive assessment of attention and that attention is a viable target for rehabilitative efforts.
