Long-term Depression01:05

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.
Regression Toward the Mean01:52

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...
Depressive Disorders: Etiology01:27

Depressive Disorders: Etiology

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...
Kaplan-Meier Approach01:24

Kaplan-Meier Approach

The Kaplan-Meier estimator is a non-parametric method used to estimate the survival function from time-to-event data. In medical research, it is frequently employed to measure the proportion of patients surviving for a certain period after treatment. This estimator is fundamental in analyzing time-to-event data, making it indispensable in clinical trials, epidemiological studies, and reliability engineering. By estimating survival probabilities, researchers can evaluate treatment effectiveness,...
Depressive Disorders: MDD and Dysthymia01:27

Depressive Disorders: MDD and Dysthymia

Depressive disorders are a group of mental health conditions characterized by pervasive feelings of sadness, diminished pleasure in life, and a significant impact on daily functioning. These conditions are most prevalent in individuals during their 30s and affect women at twice the rate of men. Contrary to popular belief, younger individuals are generally more susceptible to these disorders than older adults. Two key types of depressive disorders include Major Depressive Disorder (MDD) and...
Survival Curves01:18

Survival Curves

Survival curves are graphical representations that depict the survival experience of a population over time, offering an intuitive way to track the proportion of individuals who remain event-free at each time point. These curves are widely used in fields such as medicine, public health, and reliability engineering to visualize and compare survival probabilities across different groups or conditions.
The Kaplan-Meier estimator is the most common method for constructing survival curves. This...

Summary
This summary is machine-generated.

Research on depression and suicide has surged since 1990. Despite increased publications, the growth rate for depression and suicide research is slower than for other conditions like psoriasis.

Area of Science:

  • Bibliometrics
  • Psychiatry
  • Public Health

Background:

  • Depression is a leading global cause of suicide.
  • Numerous studies link depression and suicide, yet a comprehensive overview of global research is lacking.

Purpose of the Study:

  • To analyze long-term trends and recent developments in global research on depression and suicide.
  • To evaluate research activities and publication patterns in this field.

Main Methods:

  • Utilized scientometric methods and density-equalizing calculations.
  • Analyzed publications on depression and suicide from 1900 to 2007.
  • Searched the Web of Science database.

Main Results:

  • Publications dramatically increased between 1990 and 2007.
  • Archives of General Psychiatry showed the highest average citation rate.
  • Country publications correlated with Gross Domestic Product and Purchasing Power Parity; Russia had the highest male suicide rate among G8 countries despite low publication output.

Conclusions:

  • Research on depression and suicide has increased significantly since 1990.
  • The growth rate of this research is lower compared to fields like psoriasis and rheumatoid arthritis.
