A common nutrient deficiency may be silently harming young brains

Scientists studying young adults with obesity discovered early indicators of brain stress that resemble patterns seen in cognitive impairment. The group showed higher inflammation, signs of liver strain and elevated neurofilament light chain, a marker of neuron injury. Low choline levels appeared closely tied to these changes. The results hint that early metabolic disruptions may quietly influence the brain long before symptoms emerge.
