Stress and Mental Health01:30

Stress and Mental Health

348
Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.
Individuals with depression often experience challenges in both their personal and professional...

Substance Use Disorders Affecting Sleep

281
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

Diagnostic and Statistical Manual of Mental Disorders (DSM)

532
The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...

Classification of Illness01:17

Classification of Illness

8.3K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

Area of Science:

  • Psychiatry and Mental Health
  • Health Informatics
  • Machine Learning in Healthcare

Background:

  • Learning health systems aim to use data for improved clinical care.
  • Leveraging patient-reported mental health and substance use data for personalized predictions remains underexplored.

Purpose of the Study:

  • To develop and validate a general Bayesian prediction algorithm for forecasting patient-specific mental health symptoms and substance use.
  • To assess the algorithm's performance in predicting depression, anxiety, mania, and alcohol, heroin, and cocaine use.

Main Methods:

  • Developed a Bayesian prediction algorithm utilizing self-reported psychiatric symptoms and substance use data.
  • Validated the algorithm on 2444 participants across two clinical cohorts (National Network of Depression Centers and Johns Hopkins HIV Clinical Cohort).
  • Compared algorithm predictions against observed symptoms and substance use outcomes.

Main Results:

  • Achieved high predictive accuracy for mental health symptoms: AUCs ranging from 0.77 to 0.85 for depression, anxiety, and mania.
  • Demonstrated strong performance in predicting substance use: AUCs of 0.90-0.92 for alcohol, heroin, and cocaine use.
  • Individual predictions showed significant accuracy in both clinical cohorts.

Conclusions:

  • The developed Bayesian algorithm offers a robust, mathematically grounded method for patient-specific predictions.
  • This approach can be adapted for various psychiatric symptoms and substance use, enhancing learning health systems.
  • The algorithm has the potential to provide real-time, patient-specific guidance at the point of care.
