The aim of this study is to test the efficacy of a nature-based cognitive intervention to restore cognitive function among women treated for breast cancer.
Cognitive dysfunction is a kind of cluster of commonly reported neurotoxic symptoms following cancer diagnosis and treatment, especially chemotherapy. Our previous studies found that breast cancer patients and survivors had greater difficulties in performing attention, working memory, and executive function tasks and had persistent neural inefficiency of an executive network of the brain than disease and treatment counterparts.
The aim of this study is to test the efficacy of a nature-based cognitive intervention to restore cognitive function among women with cognitive complaints after breast cancer treatment. All participants will receive the initial screening to verify their cognitive status and then will be randomly assigned to the experimental or control group. The experimental group will receive a 4-week cognitive intervention by using a VR headset. Each VR content includes 10-12 video scenes with visual and auditory stimuli that were generated from nature.

| Virtual reality-based cognitive intervention | Behavioral | This intervention consists of 12 different VR contents that were developed for this trial. Each content includes 10-12 scenes with visual and auditory stimuli generated from nature. Participants will view 3D nature videos using a VR headset for 20 minutes every other day, three times per week for one month. |
