概括
初级脑瘤患者的认知概况预测了与放射治疗相关的皮质缩. 治疗前的认知状态有助于识别患有脑结构变化和放射治疗 (RT) 后认知衰退风险较高的个体.
科学领域:
- 神经科学是一个神经科学.
- 在瘤学瘤学.
- 放射学 放射学是一门学科.
背景情况:
- 主要脑瘤的放射治疗 (RT) 可以导致神经毒性.
- 大脑结构的纵向变化,特别是皮质缩,是RT后的一个担忧.
- 了解预先治疗预测缩的因素对于患者管理至关重要.
研究的目的:
- 为了研究在RT之前和之后长达1年的原发性脑瘤患者皮质缩的纵向模式.
- 为了比较不同认知障碍表型之间的缩率.
- 确定RT前的认知概况是否预测RT后皮质缩的程度和位置.
主要方法:
- 这是一项针对85名原发性脑瘤患者 (20-72岁) 的前性观察性研究.
- 分裂,部分大脑RT被管理.
- 皮质缩率在基线,3个月,6个月和RT后12个月使用多级建模分析.
- 在最小的,一般的和口头记忆障碍表型中对缩的比较.
主要成果:
- 最小损伤表型没有显示显著的皮层厚度变化.
- 一般化损伤表型表现出广泛的,双半球缩,特别是在左前中心环,侧皮和前极.
- 语言记忆障碍表型显示左上和上皮层的焦点缩.
- 受影响地区的年均缩率在3.5%至8.7%之间.
结论:
- 在初级脑瘤患者的治疗前认知概况对与RT相关的皮质缩模式和风险有信息.
- 识别不同的认知特征可以帮助确定患有缩和随后认知衰退风险较高的患者.
- 在RT之前的认知评估可以指导个性化治疗策略和监测.

Cognitive Development During Adulthood
45
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Alzheimer's Disease: Overview
429
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...
