["To assess the effects of a picture colouring activity on the wandering (and constructive engagement) of a man with severe Alzheimer's disease.", 'The colouring activity was compared with a music listening condition and a baseline/control condition. A choice phase involving the colouring activity and the music condition was also implemented.', 'Wandering was constant during the baseline condition, but it was reduced to low or virtually 0% levels during the music condition and picture colouring activity. Moreover, the patient regularly selected the colouring activity (which also promoted constructive engagement) during the choice phase.'] Does a man with severe Alzheimer 's disease stop wandering during a picture colouring activity?
