Executive deficits characterize the initial phases of Alzheimer disease (AD) and mild cognitive impairment (MCI), and are clinically correlated to neuropsychiatric symptoms and functional loss. The aim of this study was to determine the accuracy of the Behavioral Assessment of the Dysexecutive Syndrome test (BADS) for comparing the performance between patients with amnestic MCI (aMCI) and mild AD and for detecting early signs of alterations in executive functions. BADS was performed on 60 healthy controls, 20 patients with aMCI, and 40 mild probable AD patients (20 early-onset AD patients and 20 late-onset AD patients). Significant differences in battery performance were found among groups on the BADS subtests Rule Shift Cards, Program of Action, Zoo Map, 6 Modified Elements, and 3 total scores. Early changes in executive functions were detected in both AD (irrespective of age of onset) and aMCI patients. The BADS proved useful for differentiating between these patient groups. Our results confirmed the presence of early alterations in executive functions among aMCI and mild AD patients.

Background: Concurrent exercise (CE), an emerging exercise modality characterized by sequential bouts of aerobic (AE) and resistance exercise (RE), has demonstrated acute benefits on executive functions (EFs) and neuroelectric P3 amplitude. However, the effect of acute CE on inhibitory control, a sub-component of EFs, and P3 amplitude remains inconclusive. Moreover, exploring the mechanisms underlying the effects of acute exercise on EFs contributes to scientific comprehension, with lactate recognized as a crucial candidate positively correlated with EFs.

This study investigated the single and combined effects of environmental heat stress and physical exercise on executive function (EF) performance, prefrontal cortex oxygenation, thermoregulatory responses and subjective perceptions. Sixteen subjects participated in four experimental sessions: two under moderate environmental conditions (23 °C), with and without physical exercise (R23, E23), and two under hot environmental conditions (35 °C), with and without physical exercise (R35, E35). In each session, participants completed EF tasks before and after 1 h of passive rest or 45 min of moderate-intensity cycling followed by 15 min of rest.

This study examined the interplay of psychopathic traits, executive functioning, and antisocial behavior among adjudicated youth, with a focus on the potential moderating role of executive function. The current study uses data from the Pathways to Desistance dataset was examined, utilizing the Psychopathy Checklist: Youth Version (PCL-YV) and the Stroop Color-Word Task to measure psychopathic traits and executive functioning, respectively. Violent and property offending frequencies were self-reported.

Objectives: The oldest old adults (90+) constitute the fastest growing demographic at highest dementia risk among older adults. Depression, a common risk factor, inherently presents with heterogeneous clinical manifestations. Here, we explored the associations of the predominant depression dimensions with cognition in the LifeAfter90 study.
View Article and Find Full Text PDFExecutive functions, including working memory, are typically assessed clinically with neuropsychological instruments. In contrast, computerized tasks are used to test these cognitive functions in laboratory human and animal studies. Little is known of how neural activity captured by laboratory tasks relates to ability measured by clinical instruments and, by extension, clinical diagnoses of pathological conditions.
