Diabetes mellitus (DM) affects about 422 million people and is one of the leading causes of death worldwide (World Health Organization). More importantly, the burden of type 2 diabetes (T2D) has been rising relentlessly in all countries in the past three decades. However, it is estimated that a significant percentage of cases of T2D remain undiagnosed. DM is one of the major modifiable risk factors for stroke. In addition, it has been associated with adverse outcomes after stroke, including higher mortality, poorer neurological and functional outcomes, longer hospital stay, higher readmission rates, and stroke recurrence. Another outcome, the post-stroke cognitive function, and its relationship with DM, are being evaluated in the STROKOG collaboration study.
Lo et al. for the STROKOG collaboration present a meta-analysis of individual participant data (IPD) derived from seven international post-stroke cohorts with the aim to investigate the relationship between T2M and prediabetes with cognitive impairment after stroke.
