Older adults with emotional stress could be at a greater risk for dementia.
Researchers say stress such as anxiety and depression seems to make people more susceptible to the disorder.
It is unclear exactly what might cause the link.
Researchers from Rush University Medical Center in Chicago found that older adults who had higher levels of distress were more likely than others to develop dementia before they died.
Distress was not related, however, to plaques in the brain that can be related to alzheimer’s and dementia.
