Background: Unexplained neurological dysfunction, which used to be known as conversion disorder, is rare following general anaesthesia. This phenomenon is difficult to identify in this situation because medically induced dysfunction (anaesthesia) turns into unexplained dysfunction.
Case Description: A 58-year-old man remained unresponsive to any stimuli for longer than expected following uncomplicated surgery under general anaesthesia, although his vital functions were normal. It was 2 hours after the operation before a slight eyelid response was shown. He then lay motionless in bed for several hours. Complete recovery of spontaneous movement and motor functions took 12 hours. No explanation was found.
Conclusion: Unexplained neurological dysfunction can also occur following general anaesthesia. The diagnosis is made by neurological assessment. A wait-and-see approach is the management policy because the neurological dysfunction disappears spontaneously.

Subtle gait and cognitive dysfunction are common in Parkinson's disease (PD), even before most evident clinical manifestations. Such alterations can be assumed as hypothetical phenotypical and prognostic/progression markers. To compare spatiotemporal gait parameters in PD patients with three cognitive status: cognitively intact (PD-noCI), with subjective cognitive impairment (PD-SCI) and with mild cognitive impairment (PD-MCI) in order to detect subclinical gait differences.

Diabetes mellitus (DM), a chronic metabolic disorder that adversely affects the blood-brain barrier (BBB) and microglial function in the central nervous system (CNS), contributing to neuronal damage and neurodegenerative diseases. However, the underlying molecular mechanisms linking diabetes to BBB dysfunction and microglial dysregulation remain poorly understood. Here, we assessed the impacts of diabetes on BBB and microglial reactivity and investigated its mechanisms.

Nowadays, intracerebral hemorrhage (ICH) is the main cause of death and disability, and motor impairment is a common sequel to ICH. Electroacupuncture (EA) has been widely used for functional recovery after ICH. However, its role and associated regulatory mechanisms in rehabilitation after ICH remain poorly understood.

Background: Type A aortic dissection (TAAD) remains a significant challenge in cardiac surgery, presenting high risks of adverse outcomes such as permanent neurological dysfunction and mortality despite advances in medical technology and surgical techniques. This study investigates the use of quantitative electroencephalography (QEEG) to monitor and predict neurological outcomes during the perioperative period in TAAD patients.
Methods: This prospective observational study was conducted at the hospital, involving patients undergoing TAAD surgery from February 2022 to January 2023.

Resveratrol, a natural polyphenol, has shown promising neuroprotective effects in several in vivo and in vitro experimental models. However, the mechanisms by which resveratrol mediates these effects are not fully understood. Glutamate is the major excitatory neurotransmitter in the brain; however, excessive extracellular glutamate levels can affect neural activity in several neurological diseases.
