Abstract Objectives Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a significant medical challenge, with no indisputable pathophysiological mechanism identified to date. Methods Based on clinical clues, we hypothesized that 5-hydroxytryptamine (5-HT) hyperactivation implicated in the pathogenic causes of ME/CFS and associated symptoms. We experimentally evaluated this hypothesis series mouse models. Results High-dose selective serotonin reuptake inhibitor (SSRI) treatment...

Central fatigue, which is neuromuscular dysfunction associated with neurochemical alterations, an important clinical issue related to pathologic fatigue. This study aimed investigate the anti-central fatigue effect of Korean red ginseng (KRG) and its underlying mechanism. Male BALB/c mice (8 weeks old) were subjected periodic sleep deprivation (SD) for 6 cycles (forced wakefulness 2 days + 1 normal day per cycle). Simultaneously, administered KRG (0, 100, 200, or 400 mg/kg) ascorbic acid...
