In patients with early multiple sclerosis starting interferon beta-1a, serum neurofilament light chain levels predicted progression before MRI findings were considered, but did not provide independent long-term prognostic value after adjustment for baseline imaging.

In a retrospective memory-clinic cohort, greater MRI-derived brain age was associated with dementia progression among patients with subjective cognitive decline, although its incremental predictive value was limited and external validation remains necessary.

Among 29 CPAP-adherent men with severe obstructive sleep apnea, residual objective sleepiness was associated with white-matter diffusion differences, although the cross-sectional findings do not establish causality or support routine imaging.

Baseline activity in the left dorsolateral prefrontal cortex and right precuneus during working memory and emotion-regulation tasks was associated with depression severity one year later in young adults at elevated risk for affective disorders, but not with future mania symptoms.

Individuals with psychiatric disorders demonstrated reduced flexibility in brain network reconfiguration across cognitive states in a transdiagnostic neuroimaging study. The findings linked dynamic brain patterns with symptom profiles but did not establish causality or clinical applicability.

A supervised random forest classifier trained on 330 features derived from nocturnal polysomnography achieved areas under the ROC curve approaching or exceeding 0.8 for distinguishing narcolepsy type 2, idiopathic hypersomnia, and controls in a national French reference database.
