The metabolic consequences of evoked spreading depolarization in brain slices.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Spreading depolarization is a wave of neuronal and glial depolarization that propagates through brain tissue, triggering neuropeptide release and altered blood flow. It has been observed in ischemic stroke, traumatic brain injury, subarachnoid haemorrhage, epilepsy, and migraine aura. Spreading depolarization imposes a high energetic demand, and recovery impaired under metabolic substrate deficiency. Despite its clinical relevance, metabolic responses remain poorly understood, limiting therapeutic progress. We investigated metabolic effects of spreading depolarisation using an ex vivo brain slice model, aiming to characterise changes in intracellular calcium signalling, mitochondrial function, and central carbon metabolism, and to assess the impact of glucose deprivation. We further tested whether coenzyme Q10 could improve recovery under metabolically compromised conditions. Spreading depolarization increased mitochondrial activity and shifted metabolism toward anaerobic respiration and glycolysis. Glucose deprivation impaired recovery, inducing mitochondrial dysfunction and accumulation intermediates indicative of tricarboxylic acid cycle stalling and disrupted central carbon metabolism. Supplementing glucose-deprived brain slices with coenzyme Q10 shortened spreading depolarization repolarization duration, indicating enhanced metabolic recovery. These findings demonstrate that spreading depolarization imposes a significant metabolic burden, particularly under glucose limitation, and that mitochondrial-targeted interventions such as coenzyme Q10 may enhance tissue resilience in neurological disorders.
