The paper you linked mentions the diet twice, and both mentions are positive: > Early diagnosis of the GLUT1 deficiency syndrome is important because adherence to a ketogenic diet (Glossary) [15] is an effective treatment for most patients [83]; in general, ketogenic diet efficiently suppresses epileptic seizures in childhood drug-resistant epilepsy [87]. Regarding your quote, please read the sentence right before it: > A thromboembolic occlusion of a brain-supplying artery leads to an acute disruption in blood supply to a specific brain territory, causing cerebral ischemia (Figure 1b). Within minutes, glucose depletion and associated compromised bioenergetic pathways cause extensive neuronal death in the core of the infarction, and over time in the surrounding tissue [90, 91]. The sentence you quoted is in the context of a fucking stroke and has absolutely nothing to do with diet. Are you aware of that? And again, the brain still has glucose readily available (and uses it) when on a ketogenic diet. Please do try to inform yourself and/or read more carefully before judging others' views.
