Social isolation linked to lower brain volume, higher dementia risk
Social isolation is linked to lower brain volume in areas related to cognition and a higher risk of dementia, according to a recent study. The study found that social isolation was associated with a 26% increased risk of dementia, separately from risk factors like depression and loneliness.

Alcohol abuse starting over age 40 could signal dementia
Individuals who start abusing alcohol later in life - after age 40 - may be doing so secondary to an underlying neurologic condition, such as frontotemporal dementia, according to a recent study. Overall, 1.7% of US older adults meet the definition of alcohol abuse - defined as when alcohol consumption negatively impacts work or social life or leads to legal ramifications. While lifelong alcohol abuse is a known risk factor for dementia, it has been unknown whether older adults who begin abusing alcohol late in life have an underlying neurodegenerative disease.

Stats: Hispanics 1.5 times more likely to get dementia than Whites
In the United States, the Latino population is projected to have the steepest increase in Alzheimer's disease over the next 40 years, compared to other ethnic groups. Countries in Latin America and the global community of Latinos will also experience substantial increases in dementia in the near future.

Stats: Comorbidities at age 55 tied to 2.4-fold higher dementia risk
Having two or more chronic conditions (i.e., multimorbidity) in middle age is associated with an increased risk of dementia later in life, according to a longitudinal study of more than 10,000 men and women in the UK. Common chronic conditions included high blood pressure, diabetes, coronary heart disease, depression, and chronic lung disease (COPD). Thirteen such conditions were considered in the study. The results show that dementia risk is greater when these sorts of conditions develop at a younger age (mid-50s) rather than later in life. It's a message for senior living's youngest customers, as well as staff.

Reducing frailty could help prevent dementia
Frailty is a strong risk factor for dementia, even among people who are at a high genetic risk for dementia, and it might be modified through a healthy lifestyle, a recent study suggests. The findings provide more motivation to intervene early with members and residents at risk.

Clutter-free environment may not help people with dementia
While it is generally assumed that a person with dementia will be better able to carry out daily tasks such as making tea when their home space is tidy and clutter free, "there has been very little research to really test this hypothesis," says Dr. Eneida Mioshi, principal author of a recent study from the University of East Anglia, Norwich, UK. The findings challenge the assumption that people with dementia function better in clutter-free environment, and active aging professionals might want to test the results in their own communities to better inform programming and environmental strategies.
