A leading neurologist has pinpointed a single, powerful lifestyle factor common among elderly individuals who possess remarkably youthful and sharp brains. This revelation offers a practical strategy for those aiming to preserve their cognitive function well into their later years.
The Power of Social Connection
In a recent social media video, Dr Baibing Chen, known online as Dr Bing, shared insights from his clinical practice and scientific research. He highlighted a specific group he encounters: 'super agers' – people in their 80s and 90s whose memory and thinking skills rival those of individuals decades younger.
While a good diet and physical exercise are undeniably important, Dr Chen stressed that the standout habit among these super agers is their commitment to staying socially engaged. "The one thing that super agers have in common is that they stay social," he explained.
The Science Behind the Social Brain
Recent studies examining these individuals have found they tend to have a thicker anterior cingulate cortex. This is a crucial brain region linked to emotion, attention, and, significantly, social connection. When researchers compared lifestyles, the most striking difference wasn't related to diet or supplements; it was the strength and depth of their personal relationships.
Dr Chen likens meaningful social interaction to a 'full body workout' for the brain. "Every time you connect with someone, you activate brain networks for memory, empathy, attention, and language," he said. These deep connections help lower stress hormones like cortisol while boosting protective chemicals such as oxytocin and dopamine, which may aid in preserving the brain's very structure.
Combating Dementia Risk Through Community
This advice is strongly supported by leading health charities. The Alzheimer’s Society states that social isolation can increase a person’s risk of dementia by around 60 per cent. They suggest that social contact builds 'cognitive reserve' – the brain's resilience against diseases like Alzheimer's – and promotes healthier behaviours while reducing stress and inflammation.
The charity recommends several socially engaging activities to help bolster brain health:
- Adult education or learning new skills
- Group arts and crafts sessions
- Playing a musical instrument or singing
- Volunteering within the community
Official health guidance also lists loneliness and social isolation alongside untreated depression and hearing loss as key modifiable risk factors for dementia. With nearly one million people in the UK living with dementia, such lifestyle insights are increasingly vital.
Dr Chen's final recommendation is clear: for those wanting to maintain a youthful brain, don't rely solely on puzzles. "Call your friends, join a group, talk, laugh, and stay connected. That is one of the strongest predictors of staying sharp as you get older."
