概括

m.3243A>G/MT-TL1突变会导致渐进性脑功能障碍,可以通过EEG变化检测到,例如改变背景节律和增加瘤活动,即使没有类似中风的情节 (SLEs).

科学领域:

神经科学是一个神经科学.
遗传学遗传学是一个
线粒体疾病线粒体疾病

背景情况:

m.3243A>G/MT-TL1突变与MELAS综合征和较轻的MELAS谱综合征 (MSS) 有关.
这种突变的个体的纵向EEG变化尚未完全理解.

研究的目的:

系统地分析具有m.3243A>G/MT-TL1突变的个体的纵向EEG变化.
为了研究类似中风的情节 (SLEs) 对EEG模式的影响.

主要方法:

包括具有m.3243A>G/MT-TL1突变和至少两个EEG记录的成年人.
量化脑电图指标:三角形-三角形/α能量比 (ER),希古奇碎形维度 (HD) 和阳活动 (AR).
使用线性混合模型评估早期SLE的影响.

主要成果:

随着时间的推移,EEG能量比率 (ER) 在后面的地区显著增加.
在SLE之后的EEG显示出更高的ER,更低的HD,以及增加的AR趋势.

Hepatic Encephalopathy

Hepatic Encephalopathy

DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...
