Objective: Previous studies at child and youth mental health services (CYMHS) suggest that children with ADHD have poorer outcomes compared to those with other diagnoses. This study investigates this in more detail. Methods: Children with ADHD were compared to those with ASD and those with emotional disorders, on routinely collected outcomes at CYMHS in Australia ( N = 2,513) and the Netherlands ( N = 844). Results: Where the emotional disorders group reached a similar level of emotional symptoms at the end-of-treatment as the ADHD and ASD groups, the latter two groups still had higher scores on ADHD and ASD symptoms (attention and peer problems). The poorer outcomes were mainly explained by higher severity at baseline. In Australia, an ADHD and/or ASD diagnosis also independently contributed to worse outcomes. Conclusion: Those with neurodevelopmental disorders within both countries had poorer outcomes than those with emotional disorders. Services should aim to optimize treatment to ensure best possible outcomes.

Of all tuberculosis (TB) cases, 1% affects the central nervous system (CNS), with a mortality rate of up to 60%. Our aim is to fill the 'key gap' in TBM research by analyzing brain specimens in a unique historical cohort of 84 patients, focusing on granuloma formation. We describe three different types: non-necrotizing, necrotizing gummatous, and necrotizing abscess type granuloma. Our hypothesis is that these different types of granuloma are developmental stages of the same pathological process. All types were present in each patient and were mainly localized in the leptomeninges. Intra-parenchymal granulomas were less abundant than the leptomeningeal ones and mainly located close to the cerebrospinal fluid (subpial and subependymal). We found that most of the intraparenchymal granulomas are an extension of leptomeningeal lesions which is the opposite of the classical Rich focus theory. We present a 3D-model to facilitate further understanding of the topographic relation of granulomas with leptomeninges, brain parenchyma and blood vessels. We describe innate and adaptive immune responses during granuloma formation including the cytokine profiles. We emphasize the presence of leptomeningeal B-cell aggregates as tertiary lymphoid structures. Our study forms a basis for further research in neuroinflammation and infectious diseases of the CNS, especially TB.
