Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

725
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....

Operant Conditioning Intervention01:24

Operant Conditioning Intervention

441
Operant conditioning serves as a foundational principle in therapeutic interventions aimed at modifying maladaptive behaviors. Central to this approach is the notion that behaviors, both adaptive and maladaptive, are learned through reinforcement. By analyzing the environmental factors that reinforce problematic behaviors, clinicians can design interventions to weaken these reinforcements and replace maladaptive behaviors with healthier alternatives.
In operant conditioning, behaviors that are...

Antidepressant Drugs: MAOIs and Other Agents

784
Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...

Regression Toward the Mean01:52

Regression Toward the Mean

6.8K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Timing and Consequences on Behavior01:08

Timing and Consequences on Behavior

343
In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective. 
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant...

科学领域:

  • 神经科学是一个神经科学.
  • 精神病学是一个精神病学.
  • 神经调节是一种神经调节.

背景情况:

  • 青少年心理健康障碍,如主要抑郁症 (MDD) 和行为成 (BAs),涉及到受损的奖励处理和抑制控制.
  • 重复性跨磁刺激 (rTMS) 在成年人中显示出针对这些神经回路的前景,但青少年数据有限.
  • 了解rTMS在青少年中的神经生理影响对于开发有效干预措施至关重要.

研究的目的:

  • 研究高频rTMS对MDD和BA青少年神经生理学标记和临床症状的急性,短期和中期影响.
  • 评估rTMS对奖励处理,皮质刺激性和暗示反应性的影响,使用EEG衍生事件相关潜能.
  • 评估rTMS的安全性和有效性,作为这些青少年群体的潜在治疗方法.
