Postoperative spinal subdural hygroma without incidental durotomy: illustrative cases.
J Neurosurg Case Lessons
December 2021
Background: Spinal subdural hygroma (SSH) is a rare pathological entity occurring as a complication of spinal surgery. It is different from spinal subdural hematoma due to blunt trauma, anticoagulation therapy, spinal puncture, and rupture of vascular malformations.
Observations: The authors presented five patients with SSH who received decompression for lumbar stenosis.
Article Synopsis
- REM sleep behavior disorder (RBD) is linked to dream enactment behaviors and can precede conditions like Parkinson's disease and dementia, indicating potential early neurodegeneration.
- A study comparing visual acuity among patients with RBD, idiopathic RBD (iRBD), and healthy controls found significant differences in contrast sensitivity visual acuity (CSVA) scores, with iRBD patients showing declines over time.
- The results suggest that early visual processing issues in iRBD may mirror changes seen in Parkinson's disease, indicating possible dopaminergic neuron loss in the retina.
