Article Abstract
Background: Functional cognitive disorder (FCD) may be common after a concussion, and no evidence-based treatment options are available. The current study evaluated the feasibility of a novel cognitive-behavioural therapy (CBT) protocol tailored to FCD after concussion.
Methods: Participants were randomised to CBT (n=11) or the current standard of care, cognitive rehabilitation (n=13). Both interventions consisted of eleven 50 min manualised videoconference sessions. CBT involved cognitive reappraisal and exposure-based strategies. Cognitive rehabilitation involved traditional memory compensation strategy training. Prespecified feasibility criteria were set for recruitment, perceived credibility, patient adherence, therapist protocol compliance and retention. The primary efficacy outcome was the Multifactorial Memory Questionnaire-Satisfaction (MMQ-S). The first five CBT completers completed a semistructured interview about their experience with the intervention.
Results: Most feasibility benchmarks were met, as 86% of invited patients consented, 96% of participants rated their intervention as credible, participants attended 96% of sessions, therapists covered all essential content in 94% of sessions and 100% of participants completed the post-treatment evaluation. Both groups improved on the MMQ-S. Post-treatment MMQ-S scores were similar between groups (Cohen's d=-0.05 (95% CI [-0.86, 0.75])). Two themes resulted from the qualitative data analysis, which highlighted aspects of the CBT interventions that participants valued.
Implications: This pilot trial supports the feasibility of CBT tailored to FCD after concussion and suggests that patients with FCD may benefit from either CBT or standard cognitive rehabilitation. A larger trial is needed to evaluate the efficacy of these interventions for FCD after concussion and potentially FCD in other clinical contexts.

Background: Survivors of critical illness frequently face physical, cognitive and psychological impairments after intensive care. Sensorimotor impairments potentially have a negative impact on participation. However, comprehensive understanding of sensorimotor recovery and participation in survivors of critical illness is limited.

The global surge in the population of people 60 years and older, including that in China, challenges healthcare systems with rising age-related diseases. To address this demographic change, the Aging Biomarker Consortium (ABC) has launched the X-Age Project to develop a comprehensive aging evaluation system tailored to the Chinese population. Our goal is to identify robust biomarkers and construct composite aging clocks that capture biological age, defined as an individual's physiological and molecular state, across diverse Chinese cohorts.

Visceral adiposity has been proposed to be closely linked to cognitive impairment. This cross-sectional study aimed to evaluate the predictive value of Chinese Visceral Adiposity Index (CVAI) for mild cognitive impairment (MCI) in patients with type 2 diabetes mellitus (T2DM) and to develop a quantitative risk assessment model. A total of 337 hospitalized patients with T2DM were included and randomly assigned to a training cohort (70%, n = 236) and a validation cohort (30%, n = 101).

Measurable neuromotor control deficits during functional task performance could provide objective criteria to aid in concussion diagnosis. However, many tools which measure these constructs are unidimensional and not clinically feasible. The purpose of this study was to assess the classification accuracy of a machine learning model using features measured by a clinically feasible movement-based assessment system (Mizzou Point-of-care Assessment System (MPASS) between athletes with and without concussion.
