Abstract

We investigated cerebral small vessel disease (SVD) in patients with incidental retinal vein occlusion (RVO). This retrospective, case-control, observational trial included 125 patients with RVO who underwent brain magnetic resonance imaging (MRI) and 1105 age-matched controls who underwent comprehensive medical interviews and MRI. Underlying cardiovascular diseases and MRI findings were investigated in the patients with RVO according to age (<60 or ≥60 years) and RVO occlusion level (central or branch). The characteristics of underlying cardiovascular disease and MRI findings were compared between the younger patients with RVO and age-matched controls. The cerebrovascular burden also was assessed in the younger patients with RVO. The mean age of the patients with RVO was 63.9 ± 12.1 years and the predominant underlying disease was hypertension (72/125, 58%). The older RVO group had a longer history of hypertension and less smoking history. The prevalence of cerebral SVD in the RVO group was 54% (68/125), and was significantly higher in older than in younger patients with RVO (62% [53/86] vs. 38% [15/39], P = 0.016). However, the latter had a significantly higher prevalence of cerebral SVD than their age-matched controls (38% [...Continue Reading

Aging-Associated Metabolic Disorders

Age is associated with many metabolic disorders including cardiovascular diseases, type 2 diabetes, stroke and heart disease. The mediators in aging process have been suggested to play a part in the cellular processes responsible for these metabolic disorders. Here is the latest research on aging-associated metabolic disorders.
