WHO adds seven dementia risk factors, widening prevention focus
The World Health Organization updated its dementia risk-reduction guidelines, adding seven new factors—stroke, traumatic brain injury, vision impairment, sleep problems, HIV, air pollution, and menopausal hormone therapy—joining the existing 12 and reinforcing a lifelong emphasis on brain health through learning, social activity and managing vascular risks; some factors have limited evidence and menopausal hormone therapy is not recommended solely for dementia prevention.
