Background: The widespread use of digital media by young people has generated speculations that their excessive use may have deleterious cognitive effects. Previous studies examining the association between screen time and cognitive deficits in youth have yielded mixed conclusions. We study this association using a nationally representative sample of school going adolescents in the United States.
Methods: We queried data from the 2017 and 2019 Youth Risk Behavior Survey. An analytic sample of 17,076 adolescents was analyzed using binary logistic regression. Outcome variable was cognitive difficulties (difficulty in concentrating, remembering, or making decisions), and the explanatory variable was excessive screen-time behaviors.
Results: Of the 17,076 adolescents, about one in three (34.1%) had cognitive difficulties, and 45% of adolescents engaged in excessive screen-time behaviors on an average school day. After adjusting for covariates, the odds were 1.28 times higher for adolescents who engaged in excessive screen-time behaviors to report serious cognitive difficulties compared to adolescents who did not engage in excessive screen-time behaviors (AOR = 1.28, p < .001, 95% CI = 1.18-1.40).
Conclusion: Study results support the association between excessive screen behaviors and cognitive difficulties in adolescence. Findings of this study are discussed with implications for practice and research.

Postural instability and gait disturbance are associated with abnormal stereopsis in Parkinson's disease.

Background: Visual dysfunction, including abnormal stereopsis, is a significant non-motor symptom in Parkinson's disease (PD) that can reduce quality of life and appears early in the disease. Abnormal stereopsis is associated with worsening of bradykinesia and freezing of gait, though the exact pathways linking stereopsis to motor symptoms remain unclear. Furthermore, in PD patients, the pedunculopontine nucleus and laterodorsal tegmental complex play an active role in sensorimotor control, and these areas provide cholinergic projections.

Background: Health misinformation undermines responses to health crises, with social media amplifying the issue. Although organizations work to correct misinformation, challenges persist due to reasons such as the difficulty of effectively sharing corrections and information being overwhelming. At the same time, social media offers valuable interactive data, enabling researchers to analyze user engagement with health misinformation corrections and refine content design strategies.

Purpose: This paper aims to develop a three-dimensional (3D) Alzheimer's disease (AD) prediction method, thereby bettering current predictive methods, which struggle to fully harness the potential of structural magnetic resonance imaging (sMRI) data.
Methods: Traditional convolutional neural networks encounter pressing difficulties in accurately focusing on the AD lesion structure. To address this issue, a 3D decoupling, self-attention network for AD prediction is proposed.

Introduction: Dysarthria is a motor speech disorder frequently associated with subcortical damage. However, the precise roles of the subcortical nuclei, particularly the basal ganglia and thalamus, in the speech production process remain poorly understood.
Methods: The present study aimed to better understand their roles by mapping neuroimaging, behavioral, and speech data obtained from subacute stroke patients with subcortical lesions.

Variation exists in our attitude and behaviour towards food and exercise, resulting in different degrees of health and ill health. Cultural and economic factors contribute to this, alongside personal choices, leading to a spectrum from normative eating, through disordered eating to the extremes of eating disorders (EDs). Understanding the intricate interplay between biological, psychological, and sociocultural factors to eating, exercise and body image is paramount to understand the current state regarding EDs and to deliver/develop multifaceted and individualised treatments.
