传染性疾病传染性疾病
神经科学是一个神经科学.
公共卫生公共卫生

背景情况:

疟疾是由虫寄生虫引起的,是全球重要的健康问题.
大脑疟疾是一种严重的形式,在幸存者中具有高死亡率和神经认知后果.
新出现的证据表明,即使在非脑性和无症状疟疾中也会出现损伤.

研究的目的:

审查与疟疾相关的神经认知和行为障碍不断扩大的证据.
挑战目前的大脑疟疾的定义,并提出更广泛的概念化.
突出非严重疟疾对全球神经病发率的潜在影响.

主要方法:

关于疟疾患者神经认知和行为结果的最新研究的综述.
对严重和不严重疟疾的神经成像发现的分析.
观察到的后果与当前世界卫生组织 (WHO) 对脑性疟疾的定义进行比较.

主要成果:

在严重的非脑性疟疾,非严重的疟疾和无症状的Plasmodium感染中报告了神经认知和行为障碍.
在非脑性疟疾病例的神经成像中观察到轻度血管性.
全球疟疾发病率的很大一部分可能源于非严重疟疾的后果.

结论:

疟疾引起的全身性炎症,无论大脑是否受到影响,都会损害大脑功能,并导致长期的后果.
目前的大脑疟疾的定义不足以捕捉与疟疾相关的神经损伤的全部范围.

Symbiosis

Symbiosis

Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...
