Outline of Final Research Achievements

Postpartum depression (PPD) is thought to be caused by endocrine changes during pregnancy and the puerperium that lead to emotional changes, but the neuroscientific mechanism has not been elucidated. In this study, we will observe the brain changes that occur in PPD patients using diffusion kurtosis imaging (DKI) and compare it with the Edinburgh Postnatal Depression Scale (EPDS), a standard screening method for PPD, to verify whether DKI can be a new diagnostic method for PPD. Case accumulation will take the form of a prospective cohort study, and a comparison will be made between the normal group and the PPD group. In addition, for cases in which PPD was not diagnosed, we will examine whether there is a correlation between the results of EPDS and DKI findings.

Academic Significance and Societal Importance of the Research Achievements

産後うつ(PPD)は重症化すると幼児虐待、ネグレクト、自殺企図などに発展することもあり、早期発見と適切なケアが必要とされる。2020~2022年度の妊産婦死亡の原因も自殺が第1位と報告されている。妊産婦の自殺は母体のみならず、子供の健康も著しく阻害する可能性があり、PPDの克服は緊急課題である。
PPDの早期発見の手段として広く用いられている手法がエジンバラ産後うつ質問票(EPDS)である。EPDSは簡便で侵襲がなく、医療コストもかからないという利点がある反面、自己評価のため客観性が欠けるという欠点がある。そこでより客観性と感度に優れ、PPDの病勢を反映すると予想するMRIに着目した。
