Depression links to chronic headaches through weight and diet, not physical activity alone

Depression was associated with a higher likelihood of chronic headaches in Iranian adults, with statistical models identifying body mass index and dietary iron intake as partial mediators. Physical activity was linked to depression but did not independently mediate headache outcomes, highlighting interconnected, non-causal pathways.

Small shifts in blood sodium may influence human brain excitability

This exploratory study in healthy young adults found that plasma sodium levels within the normal clinical range are significantly associated with resting motor threshold, an indirect measure of corticospinal excitability. Lower sodium concentrations were linked to lower thresholds, suggesting subtle physiological variation in electrolytes may relate to interindividual differences in brain excitability.
