The updated guidance expands the total list of recognized risk factors to 19 conditions and environmental exposures.
The short version
- The World Health Organization updated its cognitive decline guidelines to include seven new health conditions and environmental factors.
- The newly listed factors are stroke, sleep apnea, vision impairment, traumatic brain injury, air pollution, untreated HIV, and considerations regarding menopausal hormone therapy.
- Health officials noted that evidence remains limited on whether interventions for certain conditions, such as vision treatment or hormone therapy, directly prevent dementia.
Key facts

- The newly added risk factors include stroke, sleep apnea, untreated HIV, air pollution, vision impairment, traumatic brain injury, and considerations regarding menopausal hormone therapy.[Fox News]
- The WHO stated that evidence is insufficient to recommend vision treatment or menopausal hormone therapy specifically for the purpose of dementia prevention.[Fox News]
- Effective antiretroviral therapy has substantially decreased the incidence of severe dementia related to HIV, according to the guidance context.[Fox News]
What remains uncertain
- The WHO characterizes the research evidence linking air pollution exposure to cognitive decline as low to very low certainty, and notes uncertainty regarding how menopausal hormone therapy affects dementia risk in younger women.[Fox News]
