In recent years, it is becoming apparent that genes may play an important role in the development of late-onset Alzheimer's disease (LOAD), and genetic studies could unravel new clues. Based on a growing vascular hypothesis for the pathogenesis of LOAD and other dementias, there is increasing interest for environmental and genetic vascular factors. Polymorphisms in different susceptibility genes already implicated in vascular disease risk are now also being suggested as possible genetic markers for increased risk of developing LOAD; however, many of these studies have shown conflicting results. Thus far, the apolipoprotein E (APOE) gene seems to be the only vascular susceptibility factor that is agreed to play a role in the multifactorial pathogenesis of AD although emerging genetic and biological evidence is now strengthening the case for additional inclusion of angiotensin I-converting enzyme 1 (ACE1) into this category. This review will focus on the current knowledge on genetic and nongenetic vascular factors likely to be involved in LOAD, with special emphasis placed on the APOE and ACE1 genes.
