Glymphatic system and Spaceflight Associated Neuro-Ocular Syndrome

, 2022
A spectrum of ophthalmic abnormalities, including optic disc edema, globe flattening, chorioretinal folds, and hyperopic refractive error shifts, has been observed in astronauts during and after long-duration spaceflight.

Neurosurgery and the glymphatic system

Acta Neurochirurgica
Abstract The discovery of the glymphatic system has fundamentally altered our comprehension of cerebrospinal fluid transport and the removal of waste from brain metabolism. In the past decade, since its initial characterization, research on the glymphatic system has surged exponentially.

Glymphatic system and aquaporin‑4 in epilepsy

Acta Neurobiologiae Experimentalis, 2023
Over the past decade glymphatic concept has gained more and more interest. Despite some lacking data regarding structural and functional aspects, glymphatic system is widely considered the main mechanism of water and solutes transport in brain parenchyma, as well as waste clearance from the brain.

Neurotrophic Signaling, Sleep Physiology, and Retinal Neuroprotection: Integrative Mechanisms and Therapeutic Implications for Glaucoma

Sensory Neuroscience, EarlyView.
Glaucoma is increasingly understood as a neurodegenerative disorder shaped by sleep and circadian physiology, not intraocular pressure alone. Sleep loss and obstructive sleep apnea suppress BDNF–TrkB neurotrophic signaling, impair sleep‐dependent glymphatic clearance, and trigger microglial neuroinflammation and vascular insult at the optic nerve head,

Interplay between the glymphatic system and neurotoxic proteins in Parkinson's disease and related disorders: current knowledge and future directions

Neural Regeneration Research
Parkinson's disease is a common neurodegenerative disorder that is associated with abnormal aggregation and accumulation of neurotoxic proteins, including α-synuclein, amyloid-β, and tau, in addition to the impaired elimination of these neurotoxic ...

Phase coupling between eye and brain pulsations is bidirectional and modulated by the parasympathetic system – An fMREye study

Acta Ophthalmologica, EarlyView.
Abstract Purpose Physiological pulsations driven by cardiac, respiratory, and vasomotor activity are essential for solute transport within perivascular and perineural cerebrospinal fluid (CSF) pathways that support brain and eye clearance systems. Previous studies have shown that parasympathetic blockade significantly reduces ocular pulsation power and

Wasteosomes accumulate in periventricular white matter hyperintensities and exhibit complex relationships with mixed pathology, sclerotic index, and perivascular space

Brain Pathology, EarlyView.
In a mixed diagnostic cohort of pathologically diagnosed Alzheimer's disease, cerebrovascular disease, mixed pathology, and control tissue, we connected the histopathological wasteosome profile in periventricular (PV) brain sections to 7T FLAIR‐MRI confirmed PV white matter hyperintensities (WMHs), vascular stenosis and perivascular space size ...

Alteration of the glymphatic system in Alzheimer disease compared to non-Alzheimer dementia: a single center PET/MRI study [PDF]

openBackground: The glymphatic system clears brain waste via cerebrospinal fluid (CSF) perivascular routes, maintaining homeostasis, but its function is disrupted in neurological disorders such as Alzheimer disease (AD).

Non‐Alzheimer Aβ deposits in the human CNS: Implications with hypoxia and related conditions

Brain Pathology, EarlyView.
An Aβ deposit in a non‐Alzheimer's brain from an individual who experienced hypoxia/energy failure. Abstract We recently reported the deposition of Aβ in the frontal cortex of individuals who died of acute coronavirus disease 2019 (COVID‐19), or who did not have COVID‐19 but had respiratory distress, or infants with severe cardiac malformations.
