Question

Quizplus · Accepted Answer

There is substantial evidence indicating that genetics play a significant role in Alzheimer's disease. Certain genes, such as those related to the APOE allele, have been identified to increase the risk of developing Alzheimer's, while other genetic factors may offer some level of protection or decrease the risk. This complexity reflects the multifactorial nature of the disease, where both genetic predispositions and environmental factors contribute to its development and progression.
