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.

Depression: Overview

505
Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...

Stress and Mental Health01:30

Stress and Mental Health

296
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...

Panic Disorder

273
Panic disorder is an anxiety disorder characterized by recurrent and sudden minutes-long episodes of intense fear, known as panic attacks. These attacks may feel like heart attacks and often happen without warning or a specific cause. They can include symptoms such as rapid heart rate, shortness of breath, chest pain, trembling, sweating, dizziness, and a sense of helplessness. During a panic attack, individuals may feel as though they are experiencing a heart attack or are in a...

Area of Science:

  • Psychiatry
  • Public Health
  • Epidemiology

Background:

  • The COVID-19 pandemic and associated lockdowns have significantly impacted mental health globally.
  • Understanding the specific risk factors for suicidal ideation during prolonged public health crises is crucial for targeted interventions.

Purpose of the Study:

  • To identify predictive factors for suicidal ideation during the second lockdown in Greece.
  • To compare the prevalence of suicidal ideation between the first and second lockdown periods.

Main Methods:

  • A longitudinal study design was employed.
  • Data on suicidal ideation, anxiety, depression, and living conditions were collected.
  • Statistical analyses controlled for demographic factors and mental health history.

Main Results:

  • Suicidal ideation prevalence was 4.32% during the second lockdown, not significantly different from the first (4.81%).
  • Significant risk factors included anxiety, depression, prior suicidal ideation, and living with a vulnerable individual.
  • Depression emerged as the sole significant prognostic factor for suicidal ideation incidence.

Conclusions:

  • Mental health conditions like depression and anxiety are key predictors of suicidal ideation during pandemic lockdowns.
  • The persistence of suicidal ideation suggests ongoing mental health challenges requiring sustained support.
  • Targeted mental health strategies are essential for vulnerable populations during extended public health crises.
