Gastroenterology:乳糜泻患者会出现认知缺陷及脑白质变化

2020-07-02 MedSci原创 MedSci原创

目前,科学家对于腹腔疾病患者是否存在脑损伤存在争议。为了验证以前的结论,本项研究调查了英国国家生物库中所包含的乳糜泻患者神经心理功能障碍的患病率,以验证此结论。

背景与目标

目前,科学家对于腹腔疾病患者是否存在脑损伤存在争议。为了验证以前的结论,本项研究调查了英国国家生物库中所包含的乳糜泻患者神经心理功能障碍的患病率,以验证此结论。

方法

研究人员对患有腹腔疾病的参与者(n = 104;平均年龄; 63岁; 65%女性)与健康个体(对照组,n = 198;平均年龄:63岁; 67%女性)按照年龄,性别,受教育程度,体重指数和高血压进行了相匹配,所有参与者均健康。研究人员使用t检验和卡方分析比较了5组认知测验和多项选择题对6个心理健康问题的得分。磁共振成像脑数据的分组分析包括对扩散张量成像指标(平均扩散率,分数各向异性,径向扩散率,轴向扩散率)。

结果

与对照组相比,患有腹腔疾病的参与者的脑反应时间明显不足(P= .004),并且有焦虑状况的人的比例明显增高(P= .025),抑郁也增高(P= .015),自残思想的迹象(P= .025)和与健康相关的不快乐(P= .010)也明显增高。基于行径的空间统计分析表明,在广泛的位置,轴向扩散性显着增加,表明患有腹腔疾病的参与者大脑中的白质发生了变化。各组之间基于体素的形态学和Fazekas等级分析无显着差异。

结论

根据对大脑图像的分析,研究人员发现患有乳糜泻的参与者患有轻度的认知缺陷,精神健康恶化的迹象以及白质变化。这些发现支持了乳糜泻与神经和心理特征有关的概念。
