- •No family history of mental illness.
Exclusion Criteria
- •Routine MRI before treatment shows abnormal lesions in the hippocampus;
- •Contraindications for magnetic resonance examination;

Outcomes
Primary Outcomes
Incidence of cognitive decline.
Time Frame: 2 years
In a cohort of nasopharyngeal carcinoma patients undergoing intensity-modulated radiotherapy, we will observe the incidence of cognitive decline from baseline, at the end of radiotherapy, and post-treatment. The study will investigate the impact of hippocampal radiation dose on cognitive function in these patients and summarize the patterns of change.
Secondary Outcomes
- The relationship between hippocampal atrophy, radiation dose, and cognitive function after radiotherapy.(2 years)
- The relationship between hippocampal functional impairment, radiation dose, and cognitive function after radiotherapy.(2 years)
- The relationship between hippocampal microstructural damage, radiation dose, and cognitive function after radiotherapy.(2 years)
- The relationship between hippocampal microvascular injury, radiation dose, and cognitive function after radiotherapy.(2 years)
- The impact of different chemoradiation treatment modalities on the occurrence of cognitive decline.(2 years)
- The correlation between cognitive decline after radiotherapy and quality of life.(2 years)
