Understanding Super Agers:
Super agers are individuals aged 80 or older who maintain cognitive health similar to people much younger. This phenomenon is a focal point for researchers aiming to understand and promote brain health.
Role of the Entorhinal Cortex:
The entorhinal cortex, crucial for memory and navigation, is significantly more robust in super agers. Their neurons are larger and healthier than those in both Alzheimer s patients and cognitively healthy peers of the same age.
Healthy Brain Structures:
Super agers brains exhibit fewer neurofibrillary tangles, which are typical in Alzheimer s, and their anterior cingulate, important for memory and attention, is thicker. Additionally, their brains shrink more slowly over time.
Genetic Factors and Beyond:
While genetics may play a role, lifestyle choices and habits significantly impact brain health. Super agers often engage in behaviors that promote cognitive resilience.
Physical Activity:
Regular physical activity is vital for brain health. Activities like walking, climbing stairs, or dancing can provide necessary exercise and help maintain cognitive functions.
Mental Engagement:
Staying mentally active is crucial. Super agers often engage in mentally stimulating activities such as reading, playing chess, or learning new languages to keep their brains sharp.
Social Connections:
Maintaining social connections is essential for cognitive health. Super agers often have a higher density of von Economo neurons, which are involved in social processing. Staying connected with family and friends can be beneficial.
Healthy Lifestyle:
Overall, a combination of physical activity, mental engagement, and social connectivity, alongside maintaining a challenging and stimulating lifestyle, are key components in the path to becoming a super ager.
