TL;DR

Marked BW change was associated with subsequent dementia risk in young and middle-aged adults with T2DM and depression, and BW trajectories may serve as clinically observable risk markers, although associations involving extreme BW change should be interpreted cautiously.

Abstract

Type 2 diabetes mellitus (T2DM) and depression are established risk factors for dementia, yet clinically observable markers of neurocognitive vulnerability in younger adults with these comorbidities remain poorly characterized. We examined whether longitudinal body weight (BW) change is associated with incident dementia in young and middle‐aged adults with T2DM and depression.

Association Between Frailty Index and New-Onset Stroke in Middle-Aged and Elderly Chinese Adults with Gastrointestinal or Liver Diseases: A Longitudinal Cohort Study

Background: Although the frailty index (FI) has been reported to associate with stroke risk in older adults, its relationship in those with gastrointestinal (GI) or liver diseases remains unclear. We examined this association in a Chinese cohort with these comorbidities. Methods: Using baseline data from the China Heal...

Long-term risk of incident dementia following documented COVID-19 among older adults with type 2 diabetes: a propensity score-matched cohort study

Background Type 2 diabetes mellitus (T2DM) is a well-established risk factor for dementia, and COVID-19 has been associated with persistent neurological and cognitive sequelae. However, whether this association extends beyond the early post-infection period among older adults with T2DM—a population with compounded vasc...
