The World Health Organization has updated its guidance on dementia prevention as the condition continues to affect millions of families worldwide. According to the latest figures cited in the report, more than 57 million people are living with dementia globally, with nearly 10 million new cases diagnosed each year.
The revised advice highlights a newly recognized risk factor for dementia, signaling that prevention guidance is continuing to evolve as research develops. While the update points to ways people may reduce risk, it does not change the broader reality that there is still no cure for dementia.
The guidance also warns people not to rely on certain supplements as a way to prevent cognitive decline. Instead, the focus remains on evidence-based steps that support brain health, rather than products that may be marketed with stronger claims than the science supports.
One of the clearest messages in the updated recommendations is the importance of addressing hearing loss. The WHO stresses that managing hearing problems should be part of dementia risk reduction, reinforcing the link between hearing health and long-term cognitive well-being.
