Activity interventions for cognitive problems.

Cancer and its life-saving treatments often result in long-term impairments in neurocognitive functions. These neurocognitive impairments are not only problematic, but they also limit the ability to perform meaningful everyday activities critical to independence in the home, school, and community. The "bottom-up" and "top-down" models inherent in many neurological rehabilitation interventions provide a gross framework for describing interventions designed to address neurocognitive functions. Activity interventions show promise for improving performance of everyday activities, as well as improving underlying neurocognitive functions. However, additional empirical examination is warranted. Future studies examining activity interventions should clearly specify the active ingredient of the intervention, and evaluate the impact of the intervention on neurocognitive as well as activity-based outcomes.
