精神分裂症患者表现出加速的大脑衰老,早期大脑预测年龄差异 (大脑-PAD) 更高. 导致大脑PAD的大脑异常与疾病持续时间不同,影响认知功能.
科学领域:
- 神经成像是一种神经成像.
- 精神病学是一个精神病学.
- 衰老研究研究 衰老研究
背景情况:
- 精神分裂症与加速衰老和缩短端粒长度有关.
- 使用神经成像来预测大脑年龄显示,在精神分裂症中,大脑预测年龄差异 (大脑-PAD) 增加.
- 大脑-PAD,临床症状和疾病持续时间之间的关联尚未得到充分理解.
研究的目的:
- 在近期发病和慢性精神分裂症中调查大脑预测年龄差异 (大脑-PAD).
- 探索大脑-PAD,临床症状和疾病持续时间之间的关系.
- 识别导致大脑PAD的大脑区域,以及它们在疾病阶段之间的差异.
主要方法:
- 开发了大脑年龄预测模型,使用来自10,938名健康个体的结构性MRI数据.
- 在健康对照,近期出现的精神分裂症和慢性精神分裂症患者的验证模型.
- 通过多重线性回归和SHAP值分析了脑-PAD的临床关联.
主要成果:
- 患有近期发病和慢性精神分裂症的患者表现出脑PAD增加 (分别为1.2年和0.9年).
- 在右侧前额叶皮质中发现了SHAP值的显著差异.
- 在左前额叶皮层观察到分组SHAP值相互作用.
结论:
- 在精神分裂症的早期阶段,大脑-PAD增加更为明显.
- 导致大脑PAD的区域性大脑异常因疾病持续时间而异.
- 需要进行纵向研究来进一步调查这些发现.
