Lung cancer ranks first in the incidence of malignant tumors in China, which is seriously harmful to people’s life and health. Chemotherapy is an effective treatment for lung cancer, and it is also an important cause of cognitive dysfunction. Cognitive impairment is usually evaluated by subjective assessment, neuropsychological testing and neuroimaging research. The mechanism of cognitive impairment in patients with lung cancer caused by chemotherapy may include the accumulation of a large amount of endogenous tau protein in hippocampus, the induction of hippocampal neuroinflammation, and the direct killing effect of drugs on nerve cells. There is no effective treatment for chemotherapy-related cognitive impairment (CRCI), but current studies have found that cognitive education in the form of mind map, diet regulation, physical exercise and caring therapy may contribute to the improvement of cognitive function of lung cancer patients after chemotherapy. Based on the current research results, this article provides new ideas for the research and treatment of lung cancer patients with CRCI in terms of clinical characteristics, evaluation methods, influencing factors, mechanism and prevention strategies.
