This trial will compare two approaches to cognitive rehabilitation in adults with stroke and persistent mild to moderate cognitive impairment. One approach will add in-lab training on everyday activities and procedures to transfer improvements to daily life; the other approach will add in-lab training on relaxation, healthy nutrition, and healthy sleep with procedures to promote integration of lifestyle changes into everyday life. Both interventions will involve 35 hours of training. Testing will happen before and after treatment, and at 6- and 12-month follow-ups.
