概括

童年不良经历 (ACE) 可能会影响大脑健康. 这项试点研究表明,ACE可能与中年女性较低的亲脑衍生神经营养因子 (BDNF) 和更高成熟的BDNF有关.

科学领域:

神经科学是一个神经科学.
心理学心理学心理学
内分泌学在内分泌学.

背景情况:

儿童不良经历 (ACE) 与长期健康结果有关.
执行功能 (EF) 和来自大脑的神经营养因子 (BDNF) 是神经认知表现和大脑健康的关键指标.
了解ACE,EF和BDNF之间的关系对于确定潜在干预措施至关重要.

研究的目的:

调查ACE史和当前EF表现之间的关联.
检查ACE史和当前血清BDNF水平 (proBDNF和成熟的BDNF) 之间的关系.
探索当前EF性能与BDNF水平之间的联系.

主要方法:

试点研究涉及37名中年女性.
评估了ACEs史,EF性能,以及proBDNF和成熟BDNF的血清水平.
统计分析的重点是效应大小,以探索潜在的关系.

主要成果:

较高的ACE与EF得分没有直接关联.
ACEs显示了与proBDNF的潜在负相关性以及与成熟的BDNF的积极相关性.
EF评分显示与proBDNF和成熟的BDNF都有非显著的积极关系.

结论:

在这项对中年妇女超重的试点研究中,较高的ACE可能与改变的BDNF配置文件 (较低的proBDNF,更成熟的BDNF) 有关.
这些发现表明ACE和肥胖的潜在神经认知影响.
需要进行更大规模的研究来证实这些初步关联及其对大脑健康的影响.

Obesity

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Attention-Deficit/Hyperactivity Disorder

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Gut-Brain Axis

Gut-Brain Axis

The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such...
