Serum BDNF Levels

Meaning

Serum BDNF Levels refer to the quantifiable concentration of Brain-Derived Neurotrophic Factor measured in the peripheral blood circulation, serving as a widely used clinical biomarker for neuroplasticity and overall brain health. BDNF is a critical protein that supports the survival, growth, and differentiation of neurons and synapses in the central nervous system. While the serum level is an indirect measure of brain BDNF, it is highly correlated with lifestyle factors and is used in clinical research to track the impact of exercise, diet, and hormonal interventions. Maintaining adequate serum levels is a key objective for promoting cognitive longevity.
