Are people with O negative blood protected from getting dementia?

There is currently no conclusive evidence to suggest that individuals with O negative blood are specifically protected from developing dementia. Research on blood type and its potential links to various health conditions, including cognitive decline, is ongoing, but findings are often inconsistent. Other factors, such as genetics, lifestyle, and overall health, play a more significant role in dementia risk. It's essential to focus on a healthy lifestyle and regular medical check-ups for cognitive health.
