✓ Peer-reviewed alzhub usefulness score 50 out of 100. Brain tissue and pathology

Topic: Brain proteins, microglia and lab models

Hippocampal volume shrinks in late adulthood, but the neuromolecular factors that trigger hippocampal decay in aging humans remains a matter of speculation. In rodents, brain-derived neurotrophic factor (BDNF) promotes the growth and proliferation of cells in the hippocampus and is important in long-term potentiation and memory formation. In humans, circulating levels of BDNF decline with advancing age, and a genetic polymorphism for BDNF has been related to gray matter volume loss in old age.

Key findings

Why it matters

This study tested whether age-related reductions in serum levels of brain-derived neurotrophic factor are related to shrinkage of the hippocampus and memory deficits in older adults. In rodents, BDNF promotes growth and proliferation of cells in the hippocampus and is important in long-term potentiation and memory formation.
