Another null result from a trial of an intervention to improve outcomes for people with cognitive impairment

In this substantial cluster trial [1] of 1,042 stroke survivors in no less than 228 care homes, occupational therapy was not associated with improved scores for activities of daily living. Do we need a better understanding of the interaction between people and their social and physical environment to design an intervention that really will lift mood and improve the ability of elderly people with failing brains to engage with the world?
