Growing evidence suggests that immune dysregulation significantly contributes to the pathophysiology of neurodevelopmental disorders. Specifically, research into the profile of Cytokines in ADHD has identified distinct signatures that distinguish affected adolescents from healthy peers. A recent cross-sectional study analyzed adolescents aged 12 to 18 to explore the balance of T-helper cell subsets and microglial regulatory markers. Furthermore, the findings highlight a shift toward systemic inflammation in those diagnosed with the condition.
The study found that serum levels of several key markers, including IL-12, IL-17, IL-23, IL-4, and IL-10, were significantly higher in the ADHD group. Among these, IL-12 and IL-17 demonstrated the highest diagnostic yield with an AUC of 0.77. Additionally, IL-12 remained a strong independent predictor during multivariate analysis. These results indicate a proinflammatory activation dominated by Th1 and Th17 pathways. However, the elevation of IL-4 and IL-10 suggests a partially compensatory Th2 and Treg response aimed at modulating this inflammation.
Beyond T-cell activity, the study investigated microglia regulatory cytokines like IL-34 and CSF-1. While CSF-1 levels remained stable across groups, IL-34 showed an increase that nearly reached statistical significance. This suggests potential microglial divergence in ADHD pathophysiology. Consequently, these findings underscore the need for multidimensional immunophenotyping in clinical practice. Developing immune-targeted therapeutic strategies could offer a novel approach to managing symptoms in adolescents who do not respond to conventional treatments.
Research has identified significant increases in proinflammatory cytokines such as IL-12, IL-17, and IL-23, alongside compensatory increases in anti-inflammatory markers like IL-4 and IL-10.
Currently, markers like IL-12 and IL-17 show a moderate diagnostic yield (AUC of approximately 0.77). While they are strong predictors, they are not yet used as standalone diagnostic tools in routine clinical practice.
Th1 and Th17 dominance indicates a state of chronic proinflammatory activation, which may impact neural development and neurotransmitter pathways associated with attention and executive function.

An 11-year Swedish registry study of 618 uterine sarcoma patients found that minimally invasive surgery yielded survival comparable to open surgery in early stages. However, adjuvant chemotherapy conferred no survival benefit in localized or advanced disease, highlighting stage and histology as key outcomes.

With World Obesity Atlas data warning that over 41 million Indian children are overweight or obese, ICMR and NIN have unveiled a 10-point policy roadmap. The initiative calls for mandatory front-of-pack labeling, HFSS taxes, strict marketing bans, and healthier school environments to curb non-communicable diseases.
