Long-term Depression01:03

Long-term Depression

2.6K
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.

Depressive Disorders: MDD and Dysthymia

205
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...

Depression: Overview

327
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,...

Depressive Disorders: Etiology

162
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...

Summary

Depression symptoms increase years before and after a stroke occurs. These mood and fatigue symptoms in stroke survivors require long-term attention.

Area of Science:

  • Neuroscience
  • Gerontology
  • Psychiatry

Background:

  • Stroke is a leading cause of long-term disability.
  • Depressive symptoms are common after stroke but their trajectory before and after is less understood.

Purpose of the Study:

  • To investigate the longitudinal changes in depressive symptoms before and after incident stroke.
  • To identify specific symptom clusters associated with stroke.

Main Methods:

  • Analysis of 10,797 participants from the English Longitudinal Study of Ageing.
  • Propensity score matching to compare 425 incident stroke cases with stroke-free controls.
  • Multilevel models to analyze depressive symptom trajectories.

Main Results:

  • Individuals who experienced a stroke showed increased depressive symptoms before the event compared to controls.
  • Stroke survivors experienced a sustained increase in depressive symptoms post-stroke.
  • Mood and fatigue-related symptoms were most significantly different between stroke survivors and controls.

Conclusions:

  • Incident stroke is linked to persistent increases in depressive symptoms.
  • Pre-stroke increases in depressive symptoms may indicate early pathological changes.
  • Long-term care for stroke patients should address depressive and fatigue symptoms.
