Which is a risk factor for developing Alzheimer's disease?

Atherosclerosis is indeed considered a risk factor for developing Alzheimer's disease. This condition, characterized by the thickening and hardening of the arteries due to plaque buildup, can lead to reduced blood flow to the brain. This reduction in blood flow may result in damage to brain cells and affect their ability to function properly, contributing to the cognitive decline associated with Alzheimer's disease. The inflammatory processes and vascular issues related to atherosclerosis can also play a role in the development of neurodegenerative diseases, including Alzheimer's.

In contrast, regular physical exercise is typically associated with improved cognitive function and a lower risk of cognitive decline. Having a pet can provide social support and companionship, which can be protective factors against development of dementia. Consuming a diet rich in Omega-3 fatty acids has also been linked to better brain health and may support cognitive function, potentially reducing the risk of Alzheimer's.
