A new meta-analysis of data from individuals at high risk for schizophrenia finds no evidence for the dopamine hypothesis. (madinamerica.com)
The authors found no significant differences between high-risk populations and control groups when analyzing neuroimaging studies from 1960 to 2020, putting the dopamine hypothesis of the cause of "schizophrenia" in question. (madinamerica.com)
Findings indicate that dopamine and glutamate dysfunction occurs in schizophrenia but raise the question of whether it predates the onset of the disorder. (madinamerica.com)
Although there has long been criticism of the dopamine hypothesis of "schizophrenia" as the cause of the condition, including a previous meta-analysis that found no support for the hypothesis after analyzing relevant neurochemical processes, the hypothesis continues to maintain prominent status in psychiatry. (madinamerica.com)
In addition, the authors state that comparing high-risk individuals against a control sample will help determine whether dopaminergic and glutaminergic factors precede the onset of "schizophrenia," which could grant or reduce legitimacy to the causal dopamine hypothesis. (madinamerica.com)
