Alzheimer’s Gene Risk Higher For Those Widowed in Mid Life and Stay Without a Partner

Researchers in Sweden found that people who have the APOE Alzheimer's gene and who live alone in middle age after being widowed or separated from a life partner, are at higher risk of developing dementia. The study is the work of Dr Krister Hakannson, a research fellow at the Karolinska Institute in Stockholm, and colleagues, and is published in the 2 July online issue of the BMJ.
