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.

Wolfram syndrome (WFS) is characterized by youth-onset insulin-dependent diabetes and neurological deficits. Brain white matter deficiency has been reported, but its trajectory remains unclear. Applying diffusion basis spectrum imaging models longitudinally in 29 individuals with WFS (baseline ages, 5.2 to 25.8 years; maximum 7 visits) and 52 matched controls, we found that WFS is associated with microstructural alterations suggesting diminished axonal integrity, myelin content, and cellularity. These changes were present and stable early in the disease progression in visual and auditory-related regions, whereas abnormalities in the corpus callosum appeared later in adolescence and adulthood. Our results support developmental hypomyelination as a neurophenotype of WFS.

Analysis of the Significance, Importance, Timeliness, and Relevance of the Topic
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.

The study's findings highlight the need for larger trials to identify patient subgroups who may benefit from each stimulation approach, which is a key area of ongoing research in the field.
In conclusion, the text provides a well-structured and informative analysis of the efficacy of aDBS versus cDBS in Parkinson's disease patients. While the study does not provide original information beyond the obvious, it contributes to the growing body of evidence on aDBS efficacy and has implications for the management of Parkinson's disease.
ImportanceLittle is known about the impact of returning Alzheimer disease (AD) biomarkers to cognitively unimpaired (CU) research participants.
ObjectiveDoes return of research results (RoRR) negatively impact longitudinal symptoms of depression and cognition.
DesignRandomized, noninferiority, delayed-start clinical trial, 2021-2025
SettingAD biomarker research results offered to CU participants in a longitudinal study of aging
ParticipantsCU participants age [≥]65 were offered research AD biomarker results (APOE genotype and either plasma A{beta}42/40 or amyloid PET and MRI hippocampal volume) with an estimated 5-year risk of symptomatic AD.
Intervention(s) (for clinical trials) or Exposure(s) (for observational studies)147 participants were randomized to receive results either soon after consent (RoRR arm, N=73) or one year later (delayed-start arm, N=74).
Main Outcome(s) and Measure(s)Longitudinal change in Geriatric Depression Scale (GDS), Clinical Dementia Rating(R) sum of boxes (CDR-SB), and global cognitive composite. Outcomes were measured at annual assessments for a longitudinal study of aging.
Results187 participants received results: 70 in RoRR arm (average age 75, 60% female), 66 in delayed-start arm (average age 73, 53% female). The observed changes in annual measures did not differ between arms in both those with elevated amyloid (A{beta}+) and in those without elevated amyloid (A{beta}-) for GDS (A{beta}+ difference 0.7, 95% CI 0.0-1.3; A{beta}-difference -0.1, 95% CI -0.7-0.5; clinically significant decline >4.0), CDR-SB (A{beta}+ difference 0.0, 95% CI -0.1-0.1; A{beta}-difference 0.0, 95% CI 0.0-0.1; clinically significant decline >0.5), and cognitive composite (A{beta}+ difference -0.10, 95% CI -0.25-0.06; A{beta}-difference -0.05, 95% CI -0.17-0.07; clinically significant decline < -0.26). Secondary analyses found no evidence of association between RoRR and proximity to follow-up testing.
Conclusions and RelevanceIn the first randomized, delayed-start clinical trial of returning AD research results to CU older-adult participants, no effect was seen on longitudinal changes in symptoms of depression or cognition. This supports evidence that there are no harms to returning AD research results, although the results may not apply to more diverse populations not included in this study.

BackgroundPatients in socioeconomically disadvantaged neighborhoods face barriers to care. Missing BP documentation may signal gaps in risk-factor management, a crucial component of primary and secondary prevention of intracerebral hemorrhage (ICH). We tested whether neighborhood deprivation was associated with absent electronic health record (EHR) blood pressure (BP) documentation surrounding ICH and whether absent documentation predicted subsequent uncontrolled BP.
MethodsWe conducted a case-only study within the NIH All of Us Research Program. We included ICH survivors (ICD-10 I61.x, surviving >=1 year) with available ZIP3-based Deprivation Index. Deprivation was categorized as Privileged, Intermediate, or Deprived using cohort-based tertiles. We excluded BP measurements collected by All of Us. Outcomes were (1) absent EHR-derived BP documentation and (2) uncontrolled BP (mean systolic BP >=140 mmHg) during three windows: 1-365 days before ICH; 30-365 days and 1-5 years after ICH. Multivariable logistic regression tested associations adjusting for age, sex, and race/ethnicity.
Results1,474 ICH survivors were included (mean age 60.1, 50.4% female). Compared to privileged neighborhoods, those living in deprived neighborhoods had higher odds of absent EHR BP documentation in the year prior to ICH (OR 2.10, 95% CI 1.60-2.76; p<0.001), 30-365 days post-ICH (OR 2.82, 95% CI 2.14-3.73; p<0.001) and 1-5 years post-ICH (OR 2.81, 95% CI 2.13-3.71; p<0.001). Absence of EHR BP documentation in the year before ICH predicted uncontrolled BP 30-365 days (OR 1.97, 95% CI 1.36-2.85; p<0.001; N=888) and 1-5 years (OR 1.83, 95% CI 1.24-2.69; p=0.002; N=814) after ICH. Absence of BP documentation 30-365 days post-ICH also predicted uncontrolled BP 1-5 years post-ICH (OR 1.66, 95% CI 1.10-2.50; p=0.017; N=814).
ConclusionsNeighborhood deprivation is associated with persistent gaps in EHR BP documentation surrounding ICH, and absent documentation before or soon after ICH predicts subsequent uncontrolled BP. These findings highlight the need for community-level strategies that ensure equitable BP monitoring for socioeconomically disadvantaged populations.
