Although loneliness does not itself have the status of a clinical disease, it is associated with a range of negative health outcomes, including sleep disturbances, depressive symptoms, cognitive impairment, and stroke.
For the study, the team examined data involving cognitively normal adults. Specifically, they investigated whether persistent loneliness more strongly predicted the future development of dementia and AD than transient loneliness.
They also wanted to see whether this relationship was independent from depression and established genetic risk factors for AD, such as the Apolipoprotein e4 (APOE e4) allele.
These results motivate further investigation of the factors that make individuals resilient against adverse life events and urges to tailor interventions to the right person at the right time to avert persistency of loneliness, promote brain health and AD prevention, the team said.
