Physical activity patterns track with thinking and memory problems in newly

A prospective cohort study from Hong Kong reports that within six months of a lung cancer diagnosis, about one in four patients with non-small cell lung cancer (NSCLC) shows measurable cognitive impairment on objective tests, and changes in physical activity track closely with whether cognitive problems appear. The research followed 327 newly diagnosed NSCLC patients monthly for six months, using seven assessment points. Investigators led by Mu-Hsing Ho, with collaborators including Janette Vardy and Chia-Chin Lin, used the Hong Kong version of the Montreal Cognitive Assessment 5-Minute Protocol for objective cognition and a 37-item Functional Assessment of Cancer Therapy-Cognitive Function scale for subjective cognition. Patients with pre-existing cognitive impairment or dementia were excluded.
