Siblings of people with dementia face an increased risk of shortened lifespan, even when they are not diagnosed themselves with the condition, a new study has revealed.
Based on data from the Swedish Twin Registry, researchers from the University of Southern California (USC) Dornsife College of Letters, Arts and Sciences, in collaboration with researchers from Karolinska Institutet in Sweden, found that a combination of genetics and environmental factors reduce longevity in dementia patients. The same combination may also shorten the life of their siblings even without dementia, according to the study published in Alzheimer's & Dementia: The Journal of the Alzheimer's Association.
