Kubler Ross's Stages of Dying01:21

Kubler Ross's Stages of Dying

Elisabeth Kübler-Ross significantly advanced psychology's understanding of the process of dying with her influential book, On Death and Dying (1969). She focused on studying terminally ill individuals and outlined five stages commonly experienced when coping with death: denial, anger, bargaining, depression, and acceptance.
In denial, individuals reject the reality of their condition, often thinking, "This isn't true; I feel fine," as a way to protect themselves from emotional distress. Anger...
Autophagic Cell Death01:18

Autophagic Cell Death

Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.
Autophagy and Apoptosis
Autophagy can activate apoptosis. In normal conditions, the autophagy activating protein Beclin-1 and pro-apoptotic...
Ending Relationships01:28

Ending Relationships

The dissolution of intimate relationships presents complex emotional and psychological challenges, particularly when emotional bonds are strong, the relationship is long-standing, and perceived alternatives are limited. This distress often intensifies in romantic breakups, where the initiator may experience greater turmoil than the rejected partner. Contributing factors include residual attachment, guilt over causing pain, and uncertainty about how to manage the situation. The stress is further...
Psychosurgery01:30

Psychosurgery

Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
Historical Development of Psychosurgery
In the 1930s, Portuguese neurologist Antonio Egas Moniz introduced a surgical procedure designed...
The Stanford Prison Experiment03:20

The Stanford Prison Experiment

The famous and controversial Stanford Prison Experiment, conducted by social psychologist Philip Zimbardo and his colleagues at Stanford University, demonstrated the power of social roles, social norms, and scripts.
Long-term Depression01:03

Long-term Depression

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:

  • Public Health
  • Epidemiology
  • Mental Health Research

Background:

  • Suicide is a significant global health concern, prompting national prevention strategies.
  • Suicide rates exhibit considerable international variation, disproportionately affecting developing countries.
  • Trends show declining rates in the elderly but rising rates among youth, alongside demographic variations.

Purpose of the Study:

  • To review the global landscape of suicide.
  • To identify key risk factors and demographic variations associated with suicide.
  • To examine current suicide prevention strategies and their challenges.

Main Methods:

  • Systematic review of global suicide data.
  • Analysis of demographic, socioeconomic, and psychiatric factors.
  • Evaluation of existing suicide prevention approaches.

Main Results:

  • Suicide affects men more than women, with notable increases in young populations.
  • Psychiatric disorders (mood, substance-related, anxiety, psychotic, personality) are prevalent in individuals who die by suicide.
  • Risk factors include previous self-harm, family history, upbringing, media exposure, and access to means.

Conclusions:

  • Suicide prevention requires multifaceted approaches targeting high-risk groups and populations.
  • Significant challenges impede large-scale suicide prevention, particularly in developing countries.
  • Addressing psychiatric comorbidities and socioeconomic determinants is crucial for effective intervention.
