Schizophrenia: Overview and Dopamine Dysfunction
Abstract
Article AbstractSchizophrenia is a chronic, often disabling illness that affects approximately 24 million people worldwide. Unfortunately, while the majority of first-episode schizophrenia patients respond well to initial antipsychotic treatment, less than 1 in 5 will maintain recovery over 2 to 5 years, and most will experience at least 1 relapse. Dopamine dysfunction helps to explain the positive symptoms experienced by patients with schizophrenia, and targeting these pathways has made current antipsychotics effective treatments for this condition. However, these agents primarily manage the positive symptoms of the disorder, while negative and cognitive symptoms can persist. More treatments are needed that comprehensively address all presentations of the disorder.From the Division of Translational Imaging, Department of Psychiatry, Columbia University and New York State Psychiatric Institute, New York.

Prairie voles show strong OXTR expression in MLR regions, a conserved reward-processing network implicated in depression, addiction, and schizophrenia.
“Prairie voles strongly express OXTR in regions of the MLR, a conserved neural network (75) involved in reward processing and implicated in numerous human psychiatric disorders including depression (76), addiction (77), and schizophrenia (78).”

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.
