Abstract

Neuropsychiatric disorders (i.e., mood disorders and schizophrenia) and inflammation are closely intertwined, and possibly powering each other in a bidirectional loop. Depression facilitates inflammatory reactions and inflammation promotes depression and other neuropsychiatric disorders. Patients with neuropsychiatric disorders exhibit all cardinal features of inflammation, including increased circulating levels of inflammatory inducers, activated sensors, and inflammatory mediators targeting all tissues. Inflammation may contribute to the pathophysiology and clinical progression of these disorders. Of note, proinflammatory cytokines modulate mood behavior and cognition by reducing brain monoamine levels, activating neuroendocrine responses, promoting excitotoxicity (increased glutamate levels), and impairing brain plasticity. What are the sources of this chronic inflammation? Increasing evidence indicates that changes in neuroendocrine regulation, metabolism, diet/microbiota, and negative health behaviors are important triggers of inflammation. Finally, recent data indicate that early‐life stress is associated with overt inflammation prior to the development of neuropsychiatric disorders.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
