The Clinical Status of Patients With Lumbar Spinal Stenosis Reflects Their Individual Decision to Undergo or Defer Lumbar Spinal Surgery.

Objective: To evaluate whether functional, clinical, and self-reported tests reflect lumbar spinal stenosis patients' decisions to undergo or defer surgery.

Methods: Among 108 participants, 77 chose surgery (SG), and 31 opted to wait and see (WaSG) whether they got better spontaneously. Both groups were assessed at baseline (t0) and 3 months (t1), with additional self-reported measures at 6 (t2) and 12 months (t3).

Homonymous hemi-macular atrophy in multiple sclerosis.

Background: Retrograde trans-synaptic degeneration (TSD) following retro-chiasmal pathology, typically retro-geniculate in multiple sclerosis (MS), may manifest as homonymous hemi-macular atrophy (HHMA) of the ganglion cell/inner plexiform layer (GCIPL).

Objective: To determine the frequency, association with clinical outcomes, and retinal and radiological features of HHMA in people with MS (PwMS).

Methods: In this cross-sectional study, healthy controls (HC) and PwMS underwent retinal optical coherence tomography scanning.

Distinct cognitive and functional connectivity features from healthy cohorts can identify clinical obsessive-compulsive disorder.

Improving diagnostic accuracy of obsessive-compulsive disorder (OCD) using models of brain imaging data is a key goal of the field, but this objective is challenging due to the limited size and phenotypic depth of clinical datasets. Leveraging the phenotypic diversity in large non-clinical datasets such as the UK Biobank (UKBB), offers a potential solution to this problem. Nevertheless, it remains unclear whether classification models trained on non-clinical populations will generalise to individuals with clinical OCD.

Spotlight on Trans-Synaptic Degeneration in the Visual Pathway in Multiple Sclerosis.

A putative mechanism of neurodegeneration in multiple sclerosis (MS) is trans-synaptic degeneration (TSD), whereby injury to a neuron leads to degeneration of synaptically connected neurons. The visual system is commonly involved in MS and provides an ideal model to study TSD given its well-defined structure. TSD may occur in an anterograde direction (optic neuropathy causing degeneration in the posterior visual pathway including the optic radiations and occipital gray matter) and/or retrograde direction (posterior visual pathway lesions causing retinal degeneration).
