Neuropeptides

What are neuropeptides in PTSD? Neuropeptides are a class of molecules that can modulate the activity of neurotransmitters to increase or decrease the strength of synaptic signalling. Different neuropeptides are involved in different brain functions such as reward, food intake, metabolism, reproduction, social behaviours, and learning. Peripherally, they function like peptide hormones and modulate many bodily functions. What is the evidence for neuropeptides in people with PTSD? Moderate quality evidence found a large effect of lower neuropeptide Y levels in people with PTSD compared to controls without PTSD. This effect was also found in non-medicated samples. High quality evidence found…

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….

Hormonal changes

What are hormones and how do they relate to schizophrenia? Hormones are chemical messengers secreted by the endocrine glands. Hormones travel through the bloodstream to tissues and organs, and control most of the body’s major systems including heart rate, metabolism, mood, sexual function, and growth and development. Neuroactive steroids, including testosterone, dehydroepiandrosterone and its sulphide ester, are important for brain development as they influence synaptic connectivity and neuronal differentiation. Thyroid hormones also play a role in neurodevelopmental processes, such as differentiation of neural cells, synaptogenesis, and myelination. Prolactin is involved in many biological functions including reproduction, pregnancy and lactation, and…
