Conflicting study results on HRT

Some studies indicate that hormone replacement therapy has no impact on brain health in older women. Other research suggests the treatment might increase the risk of dementia for certain groups. The debate continues regarding whether these treatments preserve brain health or fail to protect against cognitive decline.

Timing and formulation matter

New investigations point to specific factors that determine the outcome of hormone therapy use. Researchers emphasize that when a woman starts treatment and which type she takes are critical variables. These key factors could explain why previous studies reached different conclusions about dementia prevention.
