Chronic exposure to high-sugar foods may alter these systems, leading to heightened cravings and a dependence on sugar. Appetite is regulated by complex neural pathways, including those in the prefrontal cortex, amygdala, and hypothalamus. Therefore, dysfunction of these areas may lead to excessive sugar intake and impulsivity. Sugar addiction also negatively affects physical health, with high-sugar intake strongly associated with obesity, diabetes, cardiovascular diseases, and other health problems. Sugar addiction can lead to weight gain and metabolic disorders, which in turn increase the risk of developing these diseases. Pharmacological and psychological interventions are the primary treatment for sugar addiction. Certain medications can reduce sugar cravings and dependence; however, their long-term efficacy and side effects require further investigation. Cognitive behavioral therapy can also help individuals change their attitudes and behaviors toward sugar, thereby enhancing their self-control.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>In summary, sugar addiction is an increasingly prevalent problem involving multiple aspects of the nervous system, behavior, and health.

Antibodies against surface-exposed antigens associated with AE were tested using cell-based assays; antibodies against intracellular antigens in PNS were detected by immunoblot and tissue-based assays.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>A total of 87 of 4347 samples and 29 of 3393 samples tested for AE- and PNS-associated antibodies, respectively, were positive. A spike in the incidence of AE-associated antibodies was observed in 2020 at 4.92 (95% CI, 3.05–7.53) per 1,000,000 person-years, coinciding with the first year of the COVID-19 “pandemic outbreak.” The cumulative incidence in the “pre-pandemic” period from 2017 to 2019 was 2.44 (95% CI, 1.66–3.46) per 1,000,000 person-years (<i>p </i>= 0.034, vs. “pandemic outbreak”), and in the “mid to late pandemic” period from 2021 to 2023, this was 2.74 (95% CI, 1.91–3.82) per 1,000,000 person-years (<i>p </i>= 0.086, vs. “pandemic outbreak”).

The subsequent decline in incidence in the “mid to late pandemic” period may be attributable to widespread vaccination and the emergence of new viral variants with less potential to induce autoimmunity. The incidence of PNS-associated antibodies was stable throughout, reinforcing its primary association with malignancy.</p>\u0000 </section>\u0000 </div>","PeriodicalId":9081,"journal":{"name":"Brain and Behavior","volume":"15 7","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/brb3.70630","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144589923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
