Question

Quizplus · Accepted Answer

Possessing more apolipoprotein (apoE4) genes increases an individual's likelihood of developing neurocognitive disorder due to Alzheimer's disease. The presence of apoE4 is associated with increased levels of beta-amyloid protein in the brain, which plays a key role in the development of Alzheimer's disease. However, having apoE4 does not necessarily increase the risk of developing vascular neurocognitive disorder.
