Significance of the Topic:
The study of sensory processing in autism spectrum disorder (ASD) is crucial due to its impact on an individual's quality of life. Up to 95% of autistic individuals experience sensory processing differences, which can lead to difficulties in social interactions, communication, and daily functioning. Understanding the complex relationship between hyper- and hyporesponsivity to sensory stimuli in ASD can provide valuable insights into the neural mechanisms underlying this condition.
Importance:
The study's findings have significant implications for the diagnosis, management, and treatment of ASD. By acknowledging the co-occurrence of hyper- and hyporesponsivity, clinicians can develop more comprehensive and targeted interventions that address the individual's unique sensory processing needs. This can improve the quality of life for autistic individuals and their families.
Timeliness:
The study's focus on the complex relationship between sensory hyper- and hyporesponsivity in ASD is especially timely. Recent advances in neuroimaging and computational modeling have enabled researchers to better understand the neural mechanisms underlying sensory processing. This study contributes to the growing body of research in this area, providing new insights that can inform the development of effective treatments and interventions.
Relevance:
The study's findings have relevance beyond ASD, as they may also apply to a broader range of neurological, psychiatric, and developmental conditions characterized by sensory processing difficulties. The "Sensory Paradox" framework proposed by the study offers a new perspective on sensory processing, which can be applied to various conditions, including ADHD, anxiety disorders, and intellectual disabilities.

Traumatic Brain Injury (TBI) triggers an acute systemic inflammatory response, which may contribute to poor long-term outcomes. Additionally, pre-existing factors associated with increased inflammation, such as age, may interact with this acute post-TBI inflammation to influence outcomes. Previous investigations of post-TBI inflammation have typically assessed small numbers of cytokines, but novel high-dimensional proteomic approaches can sensitively detect a broad range of inflammatory markers and more fully characterise post-TBI inflammation.
We analysed plasma from 84 participants in the BIO-AX-TBI cohort [n=37 acute, moderate- severe TBI (Mayo Criteria), n=22 acute non-TBI trauma (NTT), n=28 non-injured controls (CON)] on the Alamar NULISA Inflammation panel, assessing >200 inflammatory markers. The NTT group allowed differentiation of TBI-specific from general injury-related acute inflammatory responses. Inflammatory markers were correlated with plasma levels of NFL (neurofilament light), GFAP, total tau, UCH-L1 (all Simoa(R)) and S100B (Millipore); and subacute (10 days to 6 weeks post-injury) 3T MRI measures of lesion volume and white matter injury (fractional anisotropy).
Differential expression analysis identified 4 markers showing TBI-specific elevations in plasma levels (VSNL1, IL1RN/IL-1Ra, GFAP, IKBKG), whilst derangements in other inflammatory markers likely reflected a non-specific injury response. Higher VSNL1 levels were associated with greater lesion volume (rs=0.53), and higher IL1RN/IL-1Ra levels were associated with more white matter injury (rs=-0.66, both FDR-adjusted p<0.05).
The non-specific injury response was associated with functional outcome at 6-months - higher IL33 levels in those with good (Glasgow Outcome Scale-Extended, GOS-E, 5-8) versus poor (GOS-E 1-4) outcomes (W=47, FDR-corrected p=0.0024). To assess age-related effects, we calculated "inflammation age" by applying an Elastic Net model trained on a public healthy control dataset. The "age gap" ("inflammation age" minus calendar age) was greater in TBI than CON, and also greater in young participants.
In summary, the acute post-TBI inflammatory response is comprised of both TBI-specific and non-specific injury components. These inflammatory responses are associated with structural brain injury measures and overall functional outcome. We additionally find that age influences the acute inflammatory response. Our study highlights VSNL1, IL1RN/IL-1Ra and IL33 as potential inflammatory mediators of post-TBI pathophysiology.

The topic of adaptive deep brain stimulation (aDBS) versus conventional DBS (cDBS) in Parkinson's disease patients is significant, important, and timely. Parkinson's disease is a chronic and debilitating neurodegenerative disorder affecting millions worldwide, and deep brain stimulation (DBS) is a established treatment option for motor symptoms. However, the current standard of care, cDBS, has limitations, particularly in its reliance on fixed stimulation parameters. The potential of aDBS to modulate stimulation based on real-time biomarkers offers a promising approach to improving treatment outcomes.

Frontotemporal Dementia (FTD) is a neurodegenerative disorder characterized by extensive atrophy in the frontal and temporal lobes of the brain as well as high cerebrovascular burden. While anatomical Magnetic Resonance Imaging (MRI) is well established for quantifying brain atrophy in FTD, the variability in (pre-)processing methods limits the generalizability and comparability of findings. This study systematically compared the robustness and sensitivity of multiple widely used neuroimaging approaches, namely Deformation-Based Morphometry (DBM), Voxel-Based Morphometry (VBM), Cortical Thickness (CT), and segmentation-based Volumes, in detecting atrophy across FTD subtypes. We processed 732 T1-weighted MRI scans from 156 participants with FTD and 139 healthy controls from the Frontotemporal Lobar Degeneration Neuroimaging Initiative using our in-house pipeline PELICAN for volumetric measures and FreeSurfer for CT and segmentations. Visual quality control at each step of the pipelines revealed significantly higher failure rates for CT (38.52%) and segmentations (23.63%) relative to volumetric measures (2.04% DBM, 3.05% VBM). We then applied linear-mixed effects models to assess each metrics sensitivity in detecting differences between FTD groups and controls as well as longitudinal anatomical changes. While CT yielded effect sizes comparable to VBM and DBM when analyzing the same subset of successfully processed scans, VBM and DBM demonstrated enhanced power to detect effects due to lower failure rates and higher participant retention in the full sample. Overall, we demonstrate that image processing methodology and pipeline selection profoundly influences effect sizes and statistical power to detect meaningful between-group differences or longitudinal changes. In the FTD cohort examined here, volumetric measures (DBM and VBM) yielded sufficiently robust results to maintain adequate statistical power for capturing atrophy patterns after quality control procedures.
