  • Fronto-striato network function is reduced in major depressive disorder

    Open Access•Reoto Kijima, Keita Watanabe et al.•ARTICLE•Frontiers in Psychiatry•2024

    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

    Open Access•Enkhmurun Chibaatar, Keita Watanabe et al.•ARTICLE•Frontiers in Psychiatry•2023

    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: Associations with plasma levels of brain-derived neurotrophic factor and psychiatric symptoms

    Open Access•Tomoya Natsuyama, Naomichi Okamoto et al.•ARTICLE•Frontiers in Psychiatry•2023

    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: Identifying Their Associations With Suicide Risk

    Open Access•Naomichi Okamoto, Atsuko Ikenouchi et al.•ARTICLE•OMEGA - Journal of Death and Dying•2023

    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 …

  • A Metabolomics Study of Serum in Hospitalized Patients With Chronic Schizophrenia

    Open Access•Naomichi Okamoto, Atsuko Ikenouchi et al.•ARTICLE•Frontiers in Psychiatry•2021

    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…
