Stress and Mental Health

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...

This period is marked by an increased ability to adapt to others' perspectives and a more nuanced understanding of others' mental states, a skill that is foundational for social problem-solving and conflict avoidance. The development of cognitive empathy relies heavily on the theory of mind — the...

Deleterious Substances in Aggregate

561
Deleterious substances in aggregates can be detrimental to the quality and durability of concrete. These substances include organic impurities like loam, which interfere with cement hydration and are usually present in the sand. These prevent a good bond between aggregate and cement paste. Organic impurities can be detected using the colorimetric test, where the darkness of a solution after agitation indicates the level of organic content.
Another type of impurity is clay and fine material that...

Higher Mental Functions of the Brain: Language

3.9K
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Settings providing this type of healthcare include physician offices, public health clinics, school nursing, and community health nursing.
In 1978, international leaders convened in Alma-Ata, Kazakhstan, for what would be a pivotal event in global health. The Alma-Ata Declaration was the first to call...

Area of Science:

  • Adolescent health
  • Mental health research
  • Substance use studies

Background:

  • Early adolescence is a critical period for mental health and substance use development.
  • Understanding the interplay between substance use and mental health problems in youth is crucial for effective intervention.
  • School-based samples provide a valuable opportunity to assess population-level trends in adolescent health.

Purpose of the Study:

  • To investigate the relationship between substance use and mental health problems in early adolescents.
  • To examine mental health service utilization among adolescents with substance use and mental health concerns.
  • To identify risk factors and patterns of co-occurring disorders in a school-based population.

Main Methods:

  • A survey was administered to 1,360 grade 7 and 8 students across four regions in Ontario, Canada.
  • The study adapted measures from the Ontario Student Drug Use and Health Survey for demographics, substance use, and service utilization.
  • Mental health problems were assessed using the Global Assessment of Individual Needs - Short Screener, with distress defined as fair or poor self-rated mental health.

Main Results:

  • Over 30% of students exceeded thresholds for internalizing and/or externalizing problems, yet fewer than half received mental health services.
  • Substance use, particularly cannabis, was significantly associated with increased odds of mental health problems and distress.
  • A strong association was found between substance use problems and concurrent mental health problems, especially in girls.

Conclusions:

  • Early adolescent substance use is strongly associated with concurrent mental health problems in non-clinical settings.
  • Low rates of mental health service utilization underscore the need for enhanced early identification and intervention strategies.
  • Addressing substance use and mental health concurrently is essential to prevent the development of more severe, long-term disorders.
