What is BDNF?

BDNF, or Brain-Derived Neurotrophic Factor, is a protein that plays a crucial role in the brain's ability to remodel and reorganize itself through neuroplasticity. This remodeling is based on experiences, behaviors, and genetic factors. BDNF supports the growth of new neurons and the survival of existing ones, which is essential for maintaining and improving cognitive functions. Additionally, BDNF is involved in response to stress and the progression of mental health disorders such as depression. Various factors including stress can decrease BDNF levels, while activities like physical exercise can significantly increase its presence in the brain, contributing to improved mental health and cognitive functions 1.
