Abstract: Aging induces physical deterioration, loss of the blood brain barrier, neuronal loss-induced mental and neurodegenerative diseases. Hypotalamus-hypophysis-gonad axis aging precedes symptoms of menopause or andropause and is a major determinant of sensory and cognitive integrated function. Sexual steroids support important functions, exert pleiotropic effects in different sensory cells, promote regeneration, plasticity and health of the nervous system. Their diminution is associated with impaired cognitive and mental health and increased risk of neurodegenerative diseases. Then, restoring neuroendocrine axes during aging can be key to enhance brain health through neuroprotection and neuroregeneration, depending on the modulation of plasticity mechanisms. Estrogen-dependent transient receptor potential cation channel, subfamily V, member 1 (TRPV1) expression induces neuroprotection, neurogenesis and regeneration on damaged tissues. Agonists of TRPV1 can modulate neuroprotection and repair of sensitive neurons, while modulators as other cognitive enhancers may improve the survival rate, differentiation and integration of neural stem cell progenitors in functional neural network. Menopause constitutes a relevant clinical model of steroidal production decline associated with progressive cognitive and mental impairment, which allows exploring the effects of hormone therapy in health outcomes such as dysfunction of CNS. Simulating the administration of hormone therapy to virtual menopausal individuals allows assessing its hypothetical impact and sensitivity to conditions that modify the effectiveness and effciency.
