Hippocampus Preservation is the clinical and biological strategy focused on maintaining the structural volume, neuronal density, and functional integrity of the hippocampus, a brain region essential for memory consolidation and spatial navigation. Given the hippocampus’s vulnerability to chronic stress, aging, and metabolic dysregulation, preservation efforts are central to preventing cognitive impairment. Successful preservation involves actively supporting neurogenesis and synaptic plasticity within this critical structure. This objective is a cornerstone of modern neuroendocrinology and cognitive longevity protocols.
Origin
The term is derived from the anatomical name of the structure, the ‘hippocampus’ (from the Greek for seahorse, due to its shape), combined with the functional goal of ‘preservation.’ Its clinical significance grew from the observation that hippocampal atrophy is a common neuroimaging finding in conditions associated with cognitive decline and chronic stress. The focus on preservation reflects a proactive, preventative approach to brain health.
Mechanism
Preservation is achieved by mitigating the damaging effects of excessive glucocorticoid exposure, oxidative stress, and excitotoxicity, while simultaneously promoting neurotrophic signaling. Hormones such as estrogen and testosterone exhibit direct neuroprotective effects, supporting mitochondrial function and reducing inflammatory markers in hippocampal cells. Furthermore, physical exercise and complex cognitive engagement are known to stimulate the release of BDNF, directly enhancing the survival and integration of new neurons in the dentate gyrus.
