Depressive Disorders: Etiology01:27

Depressive Disorders: Etiology

182
Depressive disorders result from a complex interplay of biological, psychological, and sociocultural factors, each contributing uniquely to the development and persistence of the condition. Understanding these factors provides critical insight into the multifaceted nature of depression.
Biological Factors in Depression
Biological predispositions significantly influence the risk of developing depressive disorders. Genetic studies highlight the role of variations in the serotonin transporter...

Antidepressant Drugs: MAOIs and Other Agents

429
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...

Introduction To Survival Analysis01:18

Introduction To Survival Analysis

431
Survival analysis is a statistical method used to study time-to-event data, where the "event" might represent outcomes like death, disease relapse, system failure, or recovery. A unique feature of survival data is censoring, which occurs when the event of interest has not been observed for some individuals during the study period. This requires specialized techniques to handle incomplete data effectively.
The primary goal of survival analysis is to estimate survival time—the time...

Introspection01:29

Introspection

26
Introspection, long upheld as a reliable route to self-knowledge, involves examining one's thoughts, emotions, and mental processes. It underpins many psychological practices, from mindfulness meditation to psychotherapy and self-help strategies. However, empirical evidence challenges the accuracy of introspection as a means of understanding oneself.Limitations of Introspective InsightSeminal work by Nisbett and Wilson demonstrated that individuals are frequently unaware of the true causes...

Long-term Depression01:03

Long-term Depression

2.7K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Area of Science:

  • Psychiatry and Behavioral Sciences
  • Mental Health Research

Background:

  • Growing interest in real-time understanding of suicidal thoughts and behaviors.
  • Proliferation of studies using intensive time sampling methods.

Purpose of the Study:

  • Synthesize the feasibility of daily-level suicidal ideation capture.
  • Examine study factors influencing suicidal ideation detection.
  • Guide future research in intensive longitudinal designs.

Main Methods:

  • Systematic search of online databases (PsychINFO, ERIC, PubMed, MEDLINE).
  • Inclusion of articles assessing suicidal ideation at the daily level through December 2020.

Main Results:

  • Twenty-six articles from sixteen datasets met criteria.
  • Suicidal ideation detection varied widely (1-92% of surveys, 18-100% of participants).
  • Participant characteristics (e.g., baseline suicide risk) were key predictors, not assessment factors.

Conclusions:

  • Participant characteristics, particularly baseline suicide risk, are crucial for detecting daily suicidal ideation.
  • Targeting participants with elevated suicide risk at enrollment enhances study yield.
