Aging - MCAT Basics (from MedSchoolCoach)

What this episode covers

Aging is an essential topic for the MCAT, and in this episode, we’ll explore it from multiple angles. We start with the biological aspects of aging, including key processes like telomere shortening, cell senescence, and mitochondrial dysfunction—each providing insight into how and why cells age. From there, we dive into how aging impacts the brain, including the types of memory and cognitive functions that either decline or improve with age. Lastly, we’ll cover the sociology of aging, focusing on the life course theory, the social significance of aging, and demographic changes. Expect a comprehensive breakdown of these concepts, with real-world applications and examples to reinforce your understanding. Visit MedSchoolCoach.com for more help with the MCAT.
