From the article:

Researchers are attempting to identify those who are most vulnerable to financial exploitation in order to help protect older adults. Recent research from the Keck School of Medicine at USC suggests a connection between financial generosity and the early stages of Alzheimer’s disease. These results were recently published in the Journal of Alzheimer’s Disease.

From the article:

People who are organized, with high levels of self-discipline, may be less likely to develop mild cognitive impairment as they age, while people who are moody or emotionally unstable are more likely to experience cognitive decline late in life, according to research published by the American Psychological Association.

From the article:

Two groups from the Bolivian Amazon were studied: the Tsimane and the Moseten people. Dementia rates among older people were found to be around just 1 percent, compared with 11 percent of those 65 and older in the United States.  

 

"Something about the pre-industrial subsistence lifestyle appears to protect older Tsimane and Moseten from dementia," says psychologist Margaret Gatz, from the University of Southern California (USC).

From the article: 

Alzheimer's is an insidious brain disease marked by a slow mental decline that can develop unnoticed for decades before symptoms arise, but hidden signs of the condition might exist much sooner.  New research suggests that the thinning of a person's retina – the light-sensitive tissue that lines the back of the eye – in middle age is linked to cognitive performance in their early and adult life.

Abstract: 

Importance:  The retinal nerve fiber layer (RNFL) and ganglion cell layer (GCL) have been proposed as potential biomarkers for Alzheimer disease (AD). Although a number of studies have shown that knowing the thickness of RNFL and GCL can help differentiate between patients with AD and healthy controls, it is unclear whether these associations are observable earlier in life.  

 

Objective:  To examine whether RNFL and GCL thickness was associated with global cognitive performance in middle age and in childhood and with a decline in cognitive performance from childhood to adulthood and whether RNFL and GCL thickness was associated with decline in specific cognitive domains over the same period.
