Executive function, a domain of cognitive functioning, has been associated with postural control. Impairments in executive function, therefore, may lead to postural instability. Here, we hypothesize that cognitive flexibility may be particularly relevant to postural instability and use specifically selected cognitive assessments to evaluate cognitive flexibility and other key aspects of executive function.</p><p><strong>Objective: </strong>To examine the relationship between postural instability and cognitive flexibility in PD.</p><p><strong>Methods: </strong>We assessed 36 individuals, including 12 with PD and postural instability (PDPI+), 12 with PD without postural instability (PDPI-), and a control group of 12 age-matched individuals without PD. Cognitive assessments included the MoCA and the NIH Toolbox Cognition Battery. We also calculated a clinical balance score (CBS) during clinical evaluation. We used ANOVA, ANCOVA, Pearson correlation, and partial correlation analyses.</p><p><strong>Discussion: </strong>The PDPI+ group exhibited significant cognitive deficits compared to the control group. We observed strong negative correlations between CBS and cognitive flexibility in all participants with PD, suggesting a robust connection between cognitive flexibility and postural control. These associations remained significant after controlling for age, disease duration, and levodopa-equivalent daily dose.</p><p><strong>Conclusions: </strong>Our findings underscore the importance of the relationship between cognitive flexibility and postural control in individuals with PD. These results highlight the potential for targeted interventions to improve cognitive flexibility and, consequently, postural stability in individuals with PD.</p>","PeriodicalId":50671,"journal":{"name":"Cognitive and Behavioral Neurology","volume":"38 4","pages":"197-206"},"PeriodicalIF":1.5,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145670825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While definitions of hate vary, most agree that it can be defined as an aversion to certain others that motivates attempts to expel them through methods ranging from physical violence to passive avoidance. The evolutionary roots of group hate are in the ingroup-outgroup distinction, in which the individual favors ingroup members over outgroup members. Earlier studies on the effects of hate speech and propaganda show that the dehumanization of outgroup members facilitates hate. Although several mechanisms have been proposed, evidence suggests that dehumanization leads to hate due to the perceived failure of outgroup members to meet a moral ideal of right and wrong. As such, hate can be understood as an innate moral sentiment that enhances themes of ingroup loyalty and purity by expelling the offending outgroup. It involves regions of the brain active in social cognition, emotion, empathy, and behavioral regulation, such as the medial prefrontal cortex, inferior frontal gyrus, anterior cingulate cortex, amygdala, insula, and temporoparietal junction. By examining these neurobiological aspects of hate and understanding them in the context of the social and cultural factors that foster hate, we can gain deeper insights into this harmful phenomenon and how best to combat it.</p>","PeriodicalId":50671,"journal":{"name":"Cognitive and Behavioral Neurology","volume":" ","pages":"176-183"},"PeriodicalIF":1.5,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145349714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
