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.

Regional Terms

15.4K
Regional terms describe anatomy by dividing the body parts into different regions that contain structures involved in contributing similar functions. Using these terms helps increase the accurate description and identification of the particular region of interest or region affected by the disease.
Primarily, the human body has two major regions, the axial and appendicular regions. The axial region comprises regions from the head to the abdomen and makes up the central body axis. In contrast,...

Long-Term Memory

673
Long-term memory is a relatively permanent type of memory, capable of storing vast amounts of information over extended periods. Its storage capacity is generally considered unlimited.
Long-term memory can be categorized into two primary types: explicit and implicit memory. Explicit memory, also known as declarative memory, involves the conscious recollection of information that we deliberately try to remember, recall, and articulate. This type of memory encompasses specific facts, events, and...

Summary
This summary is machine-generated.

Hyperprolactinemia, often caused by prolactinomas, is effectively managed with dopamine-agonist (DA) drugs like cabergoline. Long-term DA therapy shows promise for disease remission, with surgery and radiotherapy as alternative treatments.

Area of Science:

  • Endocrinology
  • Neuroscience
  • Oncology

Background:

  • Hyperprolactinemia is the most common hypothalamic-pituitary dysfunction.
  • Prolactinomas are the primary cause, with microprolactinomas being more prevalent than macroadenomas.
  • Macroadenomas affect men and women equally, while microprolactinomas are more common in women.

Purpose of the Study:

  • To review the current understanding and treatment of hyperprolactinemia, focusing on prolactinomas.
  • To highlight the efficacy of dopamine-agonist therapy for macroprolactinomas.
  • To discuss alternative treatment modalities for refractory cases.

Main Methods:

  • Review of existing literature on hyperprolactinemia and prolactinoma management.
  • Analysis of treatment outcomes for dopamine-agonist therapy, surgery, and radiotherapy.
  • Discussion of emerging therapeutic strategies.

Main Results:

  • Dopamine-agonist (DA) drugs, particularly cabergoline, effectively control over 80% of macroprolactinoma cases.
  • Long-term DA therapy is associated with disease remission in a significant number of patients.
  • Pituitary surgery is a successful option for enclosed tumors, and radiotherapy is reserved for drug-resistant, non-surgically cured cases.

Conclusions:

  • Hyperprolactinemia management, especially for macroprolactinomas, is highly effective with current therapies.
  • Dopamine-agonist therapy offers a high success rate and potential for remission.
  • Further research into novel therapies is needed for refractory macroprolactinoma cases.
