Background: The many studies revealing a connection between serum uric acid (SUA) and dementia have reported conflicting results. This study sought to investigate the relations between SUA and cognitive function in older adults.
Materials And Methods: The sample was 2,767 American adults aged ≥60 years from the National Health and Nutrition Examination Survey 2011-2014. Cognitive performance was evaluated by the Consortium to Establish a Registry for Alzheimer's Disease test, animal fluency test, digit symbol substitution test, and composite z-score. Multivariate linear regression analyses were conducted to estimate the association between SUA and cognitive function.
Results: SUA level and cognitive function were significantly, positively correlated. Age significantly correlated with the association between SUA and cognitive function.
Conclusion: These findings support a connection between SUA and cognition, showing a positive link between SUA and cognitive scores among older American adults. We contend that a slight rise in uric acid within the normal range is advantageous for enhanced cognition. To confirm the precise dose-time-response relation, more tests will be needed.

Background: Serum uric acid (SUA) was a predictor of cognitive function. The association of SUA/serum creatinine ratio (Scr), which represents renal function-normalized SUA and cognitive function is unknown.
Objective: This study investigated the association of the SUA/Scr with cognitive function and the potential mediation effect of inflammation in the above relationship.
Functional identification of soluble uric acid as an endogenous inhibitor of CD38.

Article Synopsis
- - Excessive or insufficient levels of soluble uric acid (sUA) are linked to various health issues, while sUA at normal levels appears to be important for overall health, though its specific functions are not well understood.
- - This study shows that sUA can inhibit the enzyme CD38, which is involved in the breakdown of NAD, through a reversible non-competitive mechanism, particularly affecting purine metabolism.
- - At physiological levels, sUA may help to reduce systemic inflammation and peritonitis in mice, suggesting a significant role in regulating NAD availability and supporting the immune system by interacting with CD38.
Hippocampal recording with a soft microelectrode array in a cranial window imaging scheme: a validation study.

The hippocampus has a crucial role in the formation, consolidation and recall of memories as well as in navigation related processes. These functions are in the focus of neuroscience and different disciplines have contributed to this research field for decades. Two-photon imaging in awake animals is a valuable new aspect for these observations, especially when it is supported by electrophysiology.

Article Synopsis
- * 249 patients were evaluated using cognitive tests (MMSE and MoCA) alongside measurements of their SUA and lipid levels (triglycerides, LDL-C, HDL-C, and total cholesterol).
- * Findings revealed that higher SUA levels are associated with a lower risk of MCI in both PD and MSA, while lower total cholesterol levels might increase this risk in PD, underscoring the complex relationship between cognitive function and serum biomarkers in neurodegenerative diseases
