Article Abstract

Purpose: To investigate the cognitive and psychological aspects of acromegaly and to assess how disease activity may affect these outcomes.

Methods: This prospective study included patients with acromegaly who consecutively admitted to Pituitary Center between June 2021 and July 2023. Cognitive functions were assessed using a series of standardized tests targeting memory, attention, executive function, verbal fluency, and visuospatial skills. Additionally, Beck Depression Inventory (BDI), Beck Anxiety Inventory, and Acromegaly Quality of Life Questionnaire (AcroQoL) assessments were conducted. These evaluations were performed preoperatively and at the 9th month postoperatively following transsphenoidal surgery (TSS) to assess the anticipated changes in neuropsychological functions based on disease activity.

Results: A total of 19 patients with acromegaly were included. Remission was achieved through TSS alone in 9 patients, while 10 patients required postoperative somatostatin receptor ligands. Cognitive functions (Montreal Cognitive Assessment Test) were better in the remission phase compared to the initial active disease phase (23.36 ± 3.46 vs 24.93 ± 3.73; p = 0.035). Cognitive flexibility and selective attention (Stroop Test) were impaired during the active period of the disease (17.79 ± 12.31 vs 12.29 ± 8.23; p = 0.016). Memory functions (Wechsler Memory Scale-Logical Memory Test: immediate recall, delayed recall, recognition) showed improvement from the active phase to remission (p = 0.016, p = 0.003, p = 0.008; respectively). BDI scores were significantly higher in the active phase compared to remission (7.36 ± 3.48 vs 5.43 ± 3.03; p = 0.009). Additionally, AcroQoL scores were lower during the active disease phase than in the remission phase (65.30 ± 17.75 vs 80.43 ± 13.61; p = 0.007).

Conclusion: Acromegaly may impair cognitive and psychological functions, which appear to improve with effective treatment.

Go/no-go successive matching (GNG-matching) tasks are one of several procedures used to establish conditional discriminations. This study presents a systematic review aimed at comparing procedures and outcomes of empirical studies using GNG-matching tasks for the emergence of symmetry, transitive, and global equivalence relations in humans and non-humans. A total of 22 articles were analyzed-nine with nonhumans and thirteen with humans.

Objective: Although traditionally associated with mild head trauma, post-concussive symptoms are commonly reported across both healthy and other clinical populations. Existing research indicates that individuals with depression report high levels of post-concussive symptoms, though the underlying causes of this association remain unknown. The current study aimed to explore potential factors underlying this relationship: specifically, how maladaptive and adaptive self-focused cognitive coping styles, namely, rumination and reflection, respectively, differentially contribute to post-concussive symptoms.

This mixed methods study explores the relationships among mindfulness, grit, self-regulation, and L2 boredom in Chinese undergraduate English majors. Using structural equation modeling (SEM) with a sample of 516 students from various universities, the quantitative phase found that mindfulness and grit were negatively related to L2 boredom, with self-regulation partially mediating these relationships. Mindfulness and self-regulation were the strongest predictors of reduced boredom, while grit had a smaller yet significant impact.

Background: Although exercises and physical activities are beneficial for overall health, it can unfortunately result in a musculoskeletal injury that requires a surgical intervention in physically active youth. One of the major injures young athletes sustain is anterior cruciate ligament (ACL) tear, which often requires a surgical intervention. Following the ACL reconstruction (ACLR) surgery, athletes need to participate in rehabilitation and often perform return-to-sport (RTS) testing.

Introduction: This study utilized electroencephalography (EEG) to compare brain functional and effective connectivity patterns in children with reading difficulties (RD) and math difficulties (MD) during specific tasks. The aim was to identify neurophysiological distinctions between these two learning disorders, which often exhibit high comorbidity.

Methods: Data from a publicly available dataset of 28 children (11 RD, 17 MD) aged 7-13 years were analyzed.
