Long-term Depression

27.3K
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.

Transient Ischemic Attack l: Introduction

18
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms.

Summary
This summary is machine-generated.

Acute depression episodes in a patient were linked to relapsing paramedian thalamic infarctions. These brain lesions may explain the transient depressive symptoms and associated neurological deficits.

Area of Science:

  • Neurology
  • Neuropsychiatry

Background:

  • Depression is increasingly linked to central nervous system (CNS) lesions.
  • Cerebral hemisphere infarctions are commonly associated with depression.
  • The role of specific brain regions, like the thalamus, in depression requires further investigation.

Purpose of the Study:

  • To report a case study linking relapsing paramedian thalamic infarctions to episodes of acute depression.
  • To explore the potential causal relationship between thalamic lesions and depressive symptoms.

Main Methods:

  • Case report detailing a patient with recurrent depression.
  • Clinical observation of neurological and neuropsychological deficits.
  • Neuroimaging to identify brain lesions, specifically in the thalamus.

Main Results:

  • The patient experienced two distinct episodes of acute depression.
  • Both depression episodes correlated with relapsing paramedian thalamic infarctions.
  • Associated symptoms included transient neuropsychological deficits, hypersomnia, and left facial sensory disturbance.

Conclusions:

  • Paramedian thalamic infarctions can manifest with diverse neurological and psychiatric symptoms.
  • Thalamic lesions, similar to hemispheric strokes, may cause higher functional deficits.
  • The study suggests paramedian thalamic infarctions may be responsible for transient depression in this patient.
