Poor maternal mental health negatively impacts cognitive development from infancy to childhood, affecting both behavior and brain architecture. In a non-western context (Thimphu, Bhutan), we demonstrate that culturally-moderated factors such as family, community social support, and enrichment may buffer and scaffold the development of infant cognition when maternal mental health is poor. We used eye-tracking to measure early building blocks of cognition: attention regulation and social perception, in 9-month-old Bhutanese infants (N = 121). The cognitive development of Bhutanese infants in richer social environments was buffered from poor maternal mental health, while for infants in environments with lower rates of protective social environment factors, worse maternal mental health significantly predicted greater costs for infant attention, a fundamental building block cognition. International policies and interventions geared to improve maternal mental health and child health outcomes should incorporate each regions' unique family, cultural, and community support structures.

We assessed whether the negative association between maternal postpartum depression (PPD) and infants' development of joint attention (gaze following) generalizes from WEIRD (Western, Educated, Industrialized, Rich, and Democratic) to Majority World contexts. The study was conducted in Bhutan (N = 105, M = 278 days, 52% males) but also draws from publicly available Swedish data (N = 113, M = 302 days, 49% males). We demonstrate that Bhutanese and Swedish infants' development follows the same trajectory. However, Bhutanese infants' gaze following were not related to maternal PPD, which the Swedish infants' were. The results support the notion that there are protecting factors built into the interdependent family model. Despite all the benefits of being raised in a modern welfare state, it seems like Swedish infants, to an extent, are more vulnerable to maternal mental health than Bhutanese infants.

Lithium induced primary hyperparathyroidism is an uncommon endocrine side effect of long term lithium therapy. We studied the case of a 67-year-old female patient on long term lithium therapy for bipolar affective disorder, who developed resistant hypercalcaemia and parathyroid adenoma which required parathyroidectomy. Furthermore, the effect of chronic lithium therapy on parathyroid glands and serum calcium levels, its pathogenesis, and management were reviewed. Periodic monitoring of serum calcium levels in patients on long term lithium therapy should be practiced. Surgical removal of the affected parathyroid gland is an effective treatment modality in selected patients with resistant hypercalcaemia and parathyroid adenoma and/or hyperplasia. However, regular post-operative follow up is needed for early identification of recurrence in such patients.
