Social isolation is directly associated with later dementia: Study

According to a study by the University of Warwick, Social isolation is directly linked with changes in the brain structures associated with memory, making it a clear risk factor for dementia, scientists have found.

Setting out to investigate how social isolation and loneliness were related to later dementia, researchers at the University of Warwick, University of Cambridge and Fudan University used neuroimaging data from more than 30,000 participants in the UK Biobank data set.

Socially isolated individuals were found to have lower gray matter volumes of brain regions involved in memory and learning.
