1562-Cellular Landscapes of Cognitive Decline in ALS

This research utilizes multimodal spatial profiling to examine the biological factors behind cognitive decline in Amyotrophic Lateral Sclerosis (ALS). By integrating single-nucleus sequencing and spatial transcriptomics, the authors identified that different cognitive impairments arise from distinct cellular dysfunctions in the prefrontal cortex. Specifically, language deficits are linked to a broad, pan-regional response involving glial and vascular abnormalities. In contrast, executive dysfunction is associated with more localized changes in synaptic and mitochondrial activity within deep-layer neurons. The study concludes that ALS cognitive heterogeneity is driven by complex multicellular interactions that are not fully explained by traditional protein pathology. These findings provide a comprehensive cellular atlas that maps clinical symptoms to specific regional and molecular changes in the brain.References:Petrescu J, Roque C G, Jackson C A, et al.
