Fronto-striato network function is reduced in major depressive disorder
The reward system function is decreased in MDD patients, and this decrease may be more pronounced in younger patients, although further research is still needed
Volumetric assessment of individual thalamic nuclei in patients with drug-naïve, first-episode major depressive disorder
This is the first research study to investigate alterations of the various thalamic nuclei volumes in MDD patients compared with HCs. Moreover, we first analyzed the association between individual thalamic nuclei volumes and HAM-D subscale scores. Though our study may be restricted at certain levels, especially by the demographic difference between the two groups, they possibly contribute at a preliminary level to understanding the thalamic struc…
Gyrification patterns in first-episode, drug-naïve major depression
These results suggest that abnormal early cortical neurodevelopment may mediate vulnerability to MDD, independent of plasma BDNF levels and depressive symptoms
Risk Factors in Japanese Drug Overdose Patients
Several suicide attempts presented at the emergency department are due to drug overdose associated with psychiatric disorders. We examined and identified the major risk factors among Japanese drug overdose patients and several close associations of suicide risk. We enrolled 101 patients who attempted suicide by drug overdose between January 2015 and April 2018, assessed their background using the SAD PERSONS scale, and performed association rule …
Associations Between the Kynurenine Pathway, Proinflammatory Cytokines, and Brain-Derived Neurotrophic Factor in Hospitalized Patients With Chronic Schizophrenia
Purpose: The kynurenine (Kyn) pathway may play a role in the pathophysiology of schizophrenia. This pathway shows crosstalk with proinflammatory cytokines, including interleukin-1β (IL-1β), IL-6, and tumor necrosis factor-α (TNF-α), and/or brain-derived neurotrophic factor (BDNF). Moreover, Kyn metabolites affect neurotransmission and cause neurotoxicity. To date, the influence of the Kyn pathway on proinflammatory cytokines and BDNF remains to b…
Association Between Serum Insulin-Like Growth Factor 1 Levels and the Clinical Symptoms of Chronic Schizophrenia
Purpose: Insulin-like growth factor 1 (IGF-1) is a trophic mediator that is regulated by growth hormone and associated with the proliferation, development, and growth of neural cells. IGF-1 may be associated with the pathophysiology of schizophrenia, but this association remains controversial. This study aimed to investigate the relationship between serum IGF-1 levels and psychiatric symptoms in patients with chronic schizophrenia. Patients and M…
A Metabolomics Study of Serum in Hospitalized Patients With Chronic Schizophrenia
Purpose: Metabolomics has attracted attention as a new method for understanding the molecular mechanisms of psychiatric disorders. Current metabolomics technology allows us to measure over hundreds of metabolites at a time and is a useful indicator of the consequences of complex and continuous changes in metabolic profiles due to the execution of genomic information and external factors of biological activity. Therefore, metabolomics is imperativ…
