8 March 2021	New citation required and conclusions have changed	The body of evidence for the effectiveness of occupational therapy interventions for cognitive impairment poststroke has improved since the original review. However the effectiveness remains unclear. The original review found no difference between groups for the two relevant outcomes that were measured: improvement in time judgement skills and improvement in basic activity of daily living (BADL). In this update, we found that the potential benefits of occupational therapy interventions on BADL performance and global cognitive function for people with cognitive impairment after stroke have some support based on the evidence, albeit of low certainty. Only the difference on global cognitive function was of a clinical importance. There is also some support of moderate certainty for such interventions to improve visual attention slightly after the intervention, although if this is of clinical importance and maintained in the longer term is unclear. There may be little to no difference on other cognitive domains of attention, memory and executive function.
2 September 2020	New search has been performed	We reran the searches to September 2020 and revised the text as appropriate. We included 24 trials involving 1142 participants in this update compared with 1 trial with 33 participants in the original version of the review from 2010.
