Select phytoestrogen pharmaceutical compositions and methods of use for promoting neurological health and prevention of age-related
neurodegeneration, such as AD, have been developed. These select phytoestrogen formulations are composed of a number of
plant-derived estrogenic molecules and / or their structural analogues and exhibit binding preference to ERβ over ERα and
agonist activity in the brain. These ERβ-selective phytoestrogen formulations cross the blood-brain-barrier and promote
estrogen-associated neurotrophism and
neuroprotection mechanisms in the brain, without activating proliferative mechanisms in the reproductive tissues and are therefore devoid of other
estrogen-associated problematic aspects. The select phytoestrogen formulations are therapeutically useful to both women and men for sustaining neurological health and preventing age-related
cognitive decline and neurodegenerative disorders, such as AD. These are administered enterally, transdermally, transmucosally, intranasally or parenterally, in a dosage effective to prevent or alleviate
neuronal damage, effect
neuronal regeneration or sustain viability, increase expression of anti-apoptotic proteins, and / or decrease indicators of Alzheimer's
Disease. The formulations preferably contain combinations of compounds, and can be formulated for daily, sustained, delayed or weekly / monthly administration. In a preferred embodiment, these are administered to women who are in
menopause or
post menopausal, most preferably early in menopausal.
