Introduction:
The understanding and treatment of major depressive disorder (MDD) have faced challenges due to its heterogeneous clinical presentation and variable treatment outcomes, highlighting that there may exist multiple forms of depression (1). Advancements in neuroimaging have revealed disrupted affective and neurocognitive brain circuitry, offering potential insights into symptom diversity through distinct circuit-based biotypes (e.g., clustering patients based on shared brain dysregulation signatures; 1,2). This emerging approach aims to target specific circuits associated with distinct symptom clusters, such as dysphoric and anxiosomatic, offering a promising avenue for more effective and personalised treatment strategies (3,4). In this meta-analytical study, objectives were two-fold: first, to determine if the same brain pattern observed in MDD populations applies to one known subtype, those experiencing depressive symptoms during the peripartum period (PPD). Second, considering network effects that potentially support specific symptoms.
Methods:
To accomplish this, we conducted a systematic literature search in PubMed, Embase and PsychINFO to identify peer-reviewed original studies in English across brain imaging modalities (functional and structural magnetic resonance imaging [MRI], diffusion tensor Imaging [DTI], positron emission tomography [PET], near‐infrared spectroscopy [NIRS] and magnetic resonance spectroscopy [MRS]). Flow-chart of literature selection is depicted in Figure 1. We then performed a cross-modal coordinate-based meta-analysis using activation likelihood estimation (ALE) to combine peak coordinates from included studies, using GingerALE (cluster-level inference of p<0.05, with 10000 thresholding permutations) for MDD, PPD and MDD female only subtypes, respectively.
Results:
A total of 6624 MDD reports were screened for inclusion. Of these, 369 (11378 participants) were included for the MDD cluster meta-analysis. Regarding subgroup meta-analysis, we included 20 studies with only female MDD participants (318 participants). For the PPD subgroup, 592 reports were screened and 26 studies included (581 participants). Several clusters related to emotional and cognitive processing were found to be disrupted in the MDD full sample, namely right vmPFC, bilateral amygdala, left putamen and right insula (Figure 1). While for MDD female and PPD there was an overlap in the right amygdala, the right putamen and left DLPFC was stronger involved in PPD and the left VMPFC and DLPFC in MDD female (Figure 2). Furthermore, while PPD encompassed similar components as the anxiosomatic depression network, suggested by Cash et al. (4), there was no clear overlap suggesting involvement of other networks. Performing seed-based connectivity analysis from the right amygdala seed in PPD reveals involvement of somatomotor, temporal and prefrontal areas (Figure 2).

Conclusions:
Current classification systems (e.g., 13 subtypes based on symptoms, such as atypical and melancholic) aimed to personalise treatment but fail to improve treatment outcomes (2). The distinct brain patterns differentiating general MDD from PPD sustain the need for tailored treatment approaches that consider MDD subtypes on a fine-grained level. Specifically, better targeting approaches of MDD subtypes might improve non-pharmacological approaches, such as TMS (3,4), considering as well the significance of sex/gender as a biomarker shaping the effects of therapeutic response (5).
