Neuropeptides
What are neuropeptides in bipolar disorder?
Neuropeptides are a class of signalling molecules. They are protein-like molecules that are used by neurons to communicate with each other. Different neuropeptides are involved in different brain functions such as reward, food intake, metabolism, reproduction, social behaviours, and learning. For example, the neuropeptides oxytocin and vasopressin have specific effects on social behaviours.
What is the evidence for neuropeptides in people with bipolar disorder?
Moderate to low quality evidence finds no differences in oxytocin or vasopressin between people with bipolar disorder and controls without bipolar disorder.
No other neuropeptides were assessed via systematic review.
