Past studies have identified a loneliness-rumination-depression nexus. Rumination is defined as repetitive and intrusive negative thoughts and feelings, and loneliness as a gap between desired and actual social connections.

Given a widely reported high co-occurrence between loneliness and depression, a research team led by the Director of the State Key Laboratory of Brain and Cognitive Sciences, Professor Tatia M.C. Lee, Chair Professor of Psychological Science and Clinical Psychology and May Professor in Neuropsychology at HKU, sought to understand the underlying mechanisms.

The research team’s hypothesis for their study, entitled “A network analysis of rumination on loneliness and the relationship with depression”, which was recently published in Nature Mental Health, aimed to examine the connections that rumination would mediate the relationship between loneliness and depression, where a higher level of loneliness would be associated with more rumination, which would, in turn, link to a higher severity of depressive symptoms.

CLEVELAND, Ohio (Jan 15, 2025)—Artificial intelligence (AI) is positioned to make a major impact on almost every industry, including healthcare. A new study suggests that machine learning models can more quickly and affordably identify women with severe subjective cognitive decline during the menopause transition, effectively opening the door to better management of cognitive health. Results of the study are published online today in Menopause, the journal of The Menopause Society.

Nearly a third of people in the U.S. have been exposed to unregulated contaminants in their drinking water that could impact their health, according to a new analysis by scientists at Silent Spring Institute. What’s more, Hispanic and Black residents are more likely than other groups to have unsafe levels of contaminants in their drinking water and are more likely to live near pollution sources.
