Crosstalk Between Insulin and Dopamine Signaling: A Basis for the Metabolic Effects of Antipsychotic Drugs

Publication date: Available online 29 July 2016 Source:Journal of Chemical Neuroanatomy Author(s): Abigail I. Nash In the setting of rising rates of obesity and metabolic syndrome, characterized in part by hyperinsulinemia, it is increasingly important to understand the mechanisms that contribute to insulin dysregulation. The higher risk for metabolic syndrome imparted by antipsychotic medication use highlights one such mechanism. Though there is great variation in the number and types of signaling pathways targeted by these medications, the one common mechanism of action is through dopamine. Dopamine’s effects on insulin signaling begin at the level of insulin secretion from the pancreas and continue through the central nervous system. In a reciprocal fashion, insulin also affects dopamine signaling, with specific effects on dopamine reuptake from the synapse. This review probes the dopamine-insulin connection to provide a comprehensive examination of how antipsychotics may contribute towards insulin resistance.

ConclusionsThe findings of this study indicate high prevalence of metabolic risk factors among study population. This study with a large sample size would contribute to establishment of efficient interventions and programs aimed at reducing the prevalence of MetS by health staff, supervisors and policymakers.

ConclusionKappa coefficient showed that the Iranian IDF had a good agreement with International IDF and an intermediate agreement with the ATP-III. Considering more emphasis of international and Iranian IDF on waist circumference (WC), a better agreement between these two criteria is plausible. Regarding the high prevalence of abdominal obesity among Iranian population, applying these criteria to identify high risk persons might be helpful.

(Natural News) Years of research have established a positive collaboration between estrogen and vitamin D to improve bone health. Now, recent research suggests that this dynamic duo could also play a role in staving off metabolic syndrome in postmenopausal women. Metabolic syndrome is described as a cluster of conditions – such as obesity, high blood...

án G Abstract Nowadays, it is well accepted that obesity and metabolic syndrome are diseases that constitute a global public health issue. In consequence, the interest in the study of the effects these pathologies produce in the central nervous system has greatly increased in the last decades. One of the most overlooked topics in the literature is the impact they exert in sensory systems, among which is olfaction. The olfactory system is related to a number of vital functions, like the activation of defense mechanisms, contribution to appetitive and digestive reflexes, recognition of conspecifics, and even ...

Publication date: Available online 13 January 2020Source: Medical Journal Armed Forces IndiaAuthor(s): Rajvir BhalwarAbstractMetabolic Syndrome (MetS) is a clustering of specific risk factors, namely, central obesity, raised blood pressure, impaired fasting glucose, raised triglycerides, and low levels of high-density lipoprotein-cholesterol (HDL-C). This constellation is triggered by insulin resistance and its resultant hyperinsulinemia. The two most important and universally agreed causes of insulin resistance are increased body fat (particularly central obesity) and physical inactivity. Other causes include certain gene...

However, current monotherapies for metabolic syndrome fail to target the multifactorial pathology via multiple mechanisms, as well as resolving the dysfunctionality of the cells and organs of the body. We aimed to provide a comprehensive and ...
