Double-edged effects of mitochondrial stress on cognitive function / 中国医师杂志

ABSTRACT

As the populations are aging, concerns about cognitive decline are becoming a common topic in medical consultations. The occurrence of postoperative cognitive change involves many factors such as their own situation and perioperative period. Alzheimer′s disease (AD) is the main concern about postoperative cognitive change. For years it was widely believed that cognitive dysfunction caused by anesthesia, some studies suggest that anesthetics may cause mitochondrial damage, while most studies suggest that mitochondrial dysfunction may affect AD. But it is rarely noticed, that cells can maintain the stability following mitochondrial stress by a series of integrated stress responses (ISR) and alleviate mitochondrial stress in progeny. We reviewed the research progress of mitochondrial stress in AD.
