概括
严重精神疾病 (SMI) 中的炎症和认知子组,如精神分裂症和双相情感障碍,随着时间的推移是稳定的. 识别这些跨诊断群体可能有助于为更好的结果量身定制干预措施.
科学领域:
- 神经科学是一个神经科学.
- 精神病学是一个精神病学.
- 免疫学 免疫学 免疫学
背景情况:
- 炎症与严重精神疾病 (SMI) 中的认知障碍有关,但精神分裂症 (SZ) 和双相情感障碍 (BD) 中存在异质性.
- 对SMI中炎症和认知之间的纵向关系的理解有限.
- 怀疑具有不同炎症认知特征的跨诊断子组.
研究的目的:
- 研究第一发精神分裂症和双相情感障碍患者的系统性炎症和认知功能之间的关系的纵向过程.
- 在一年的时间内,在精神分裂症,双相情感障碍和健康对照中确定稳定的跨诊断性炎症认知子组.
主要方法:
- 系统性炎症 (C-反应蛋白,CRP) 和九个认知领域在基线和1年随访时被评估.
- 参与者包括第一次治疗精神分裂症 (SZ),双相情感障碍 (BD) 和健康对照 (HC).
- 使用线性混合模型和层次聚类来分析纵向变化并识别子组.
主要成果:
- 从基线到随访期间,在各组中没有观察到CRP水平的显著变化.
- 在两个时间点的病例 (SZ,BD) 和对照 (HC) 之间,认知表现不同,具有特定领域的稳定性或改善.
- 稳定的跨诊断子组出现了:"较高的炎症-较低的认知"组 (主要是SZ) 和"较低的炎症-较高的认知"组 (主要是BD和HC),前者显示较差的临床结果.
结论:
- 在SMI和健康人群中存在异质和稳定的跨诊断炎症认知子组.
- 这些子组随着时间的推移显示出一致的炎症和认知特征.
- 研究结果表明,基于这些稳定的炎症认知特征,有针对性干预的潜力.

Longitudinal Studies
141
Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Longitudinal Research
11.9K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.
