368. Brains and Hormones
Dementia is preventable through early brain protection
Dementia’s decline is a network failure driven by stress-related biology, not inevitable aging; prevention must start in midlife before irreversible injury, with hormones, sleep, and inflammation control central.
Amyloid may be a protective response marker
Amyloid beta is framed as an antimicrobial, immune-surveillance peptide that becomes harmful mainly by interfering with neuron connectivity; removing amyloid alone failed to improve cognition, shifting focus.
Hormone timing may decide brain outcomes
Estrogen receptor density is presented as the key mechanism: starting hormone therapy during perimenopause/early menopause may preserve glucose metabolism and reduce tau hyperphosphorylation, unlike later synthetic use.
