Long-term Depression01:05

Long-term Depression

33.3K
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.

Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...

Depressants

436
Depressant drugs, including alcohol and sedative-hypnotics, diminish central nervous system activity by enhancing the action of gamma-aminobutyric acid (GABA), a neurotransmitter that reduces brain activity and promotes relaxation. These substances can have various therapeutic uses but also pose significant risks, especially when misused or combined.
Alcohol is a common depressant that can induce a sense of relaxation and reduced inhibition at low doses. Contrary to its occasional...

Psychosis and Antipsychotic Drugs: Overview

904
The term "psychosis" refers to a spectrum of mental disorders characterized by abnormal thoughts, perceptions, and behaviors. It can manifest as mood disorders, dementia, delirium with psychotic features, substance-induced psychosis with psychotic features, brief psychotic disorder, delusional disorder, schizoaffective disorder, and schizophrenia. Among all these disorders, schizophrenia is the most common psychotic disorder, affecting 1% of the worldwide population. Psychotic...

Summary
This summary is machine-generated.

Adjunctive antipsychotics offer a modest benefit for major depressive disorder, particularly short-term for treatment-resistant cases with specific symptoms. Routine use is not supported, and long-term efficacy remains unproven.

Area of Science:

  • Psychiatry
  • Pharmacology

Background:

  • Major depressive disorder (MDD) is a prevalent and debilitating mental health condition.
  • Treatment resistance is a significant challenge in managing MDD, necessitating exploration of adjunctive therapies.

Purpose of the Study:

  • To evaluate the efficacy and safety of adjunctive antipsychotics in patients diagnosed with major depressive disorder.
  • To assess the current evidence for antipsychotic augmentation in antidepressant-refractory depression.

Main Methods:

  • A systematic literature search was conducted for studies published after 2010.
  • Keywords included "adjunct*", "augment*", "antipsychotic", and "depression".
  • Relevant treatment guidelines were also reviewed.

Main Results:

  • Adjunctive antipsychotics demonstrated a small but statistically significant improvement in depressive symptoms.
  • Most studies included patients with inadequate antidepressant response, not strictly treatment-resistant depression.
  • Treatment guidelines offered variable support, cautioning on side effects and lacking specificity on duration.

Conclusions:

  • Routine use of adjunctive antipsychotics for inadequate antidepressant response is not supported by current evidence.
  • Short-term use may benefit treatment-resistant depression patients with specific symptoms like severe ruminations or melancholia.
  • Further research is needed to identify responsive symptom profiles and compare adjunctive antipsychotics with alternative strategies.
