右侧垂突的存在与行为变异前性痴呆症 (bvFTD) 的晚期发病有关. 然而,它也表明bvFTD患者每年死亡风险显著增加.
科学领域:
- 神经科学是一个神经科学.
- 神经学 神经学
- 放射学 放射学是一门学科.
背景情况:
- 前性痴呆症 (FTD) 是早期痴呆症的常见原因,行为变体FTD (bvFTD) 是主要亚型.
- 前带带皮质是bvFTD中受影响的关键区域.
- 神经发育标记物Paracingulate sulcal的存在,在妊娠第三个三个月后是稳定的.
研究的目的:
- 为了研究右侧状的存在对偶发性bvFTD的临床表现和预后的影响.
- 探索这种神经发育标志物与疾病进展,发病时的年龄和bvFTD的存活率之间的关系.
主要方法:
- 从美国和荷兰的记忆诊所 (2000-2022) 追溯分析了186名零星bvFTD患者.
- 评估T1-MRI数据的两个盲目评定者,以确定右侧状突的存在.
- 结果措施包括发病时的年龄,生存率,皮质厚度和临床疾病进展,使用FTD修改的临床痴呆症评级.
主要成果:
- 患有右侧柱的个体在发病时年龄较晚 (平均差异为2.44年,P=0.02).
- 右侧状的存在与每年83%的死亡风险增加有关 (HR1.83,P<0.02).
- 没有发现右侧状的存在与基线皮质厚度或死亡时的平均年龄之间有显著的关联.
结论:
- 右侧状的存在对零星bvFTD的疾病表现和生存有影响.
- 研究结果表明,神经发育大脑储备在bvFTD中起着作用.
- 这对设计未来的bvFTD临床试验和治疗策略有影响.
