Brain Training May Help Clear Cognitive Fog Caused by Chemotherapy

Klint Finley

I’ve linked to research before casting doubt on the efficacy of “brain training” games and software (other than double n-back). But some new research reported by the MIT Technology Review is more promising:

Cancer survivors sometimes suffer from a condition known as “chemo fog”—a cognitive impairment caused by repeated chemotherapy. A study hints at a controversial idea: that brain-training software might help lift this cognitive cloud.

Various studies have concluded that cognitive training can improve brain function in both healthy people and those with medical conditions, but the broader applicability of these results remains controversial in the field.

In a study published in the journal Clinical Breast Cancer, investigators report that those who used a brain-training program for 12 weeks were more cognitively flexible, more verbally fluent, and faster-thinking than survivors who did not train. […]

“This is a well-done study—they had not just one transfer test but several,” says Hambrick, who notes that many studies of cognitive training depend on a single test to measure results. “But an issue is the lack of activity within the control group.” Better would be to have the control group do another demanding cognitive task in lieu of Lumosity training—something analogous to a placebo, he says: “The issue is that maybe the improvement in the group that did the cognitive training doesn’t reflect enhancement of basic cognitive processes per se, but could be a motivational phenomenon.”
