Prevent Cognitive Decline with Social Connection

Perhaps you have already seen the popular TED talk by Robert Waldinger. As a director of the Harvard Study of Adult Development, he discusses how following 268 Harvard sophomores since 1938 helped them understand how to live healthy and happy lives. In this blog post, we will discuss how social isolation leads to cognitive impairment, how social connections improve cognitive function, and what ways to have social connections that boost cognitive function.

Social Isolation Leads to Cognitive Impairment

Centers for Disease Control and Prevention states that loneliness is a perceived feeling of being alone, regardless of the social connections that they have. Social isolation is a lack of social connection. Some people may feel lonely even while having a lot of social relationships.

In 2022, the American Heart Association published a statement based on their systematic review of loneliness, social isolation, and their effects on heart health and cognitive function. They reported little and less robust evidence suggesting an association between social isolation and loneliness with dementia and cognitive impairment. However, they reported higher incidences of stroke and other cardiovascular diseases among those with a higher likelihood of experiencing loneliness/social isolation risk factors for dementia. Social isolation can also lead to depression, which is another element that increases the risk of dementia.

One of the exciting findings from the 2022 AHA report is that those in Generation Z (aged between 19-23 as of 2023) have the highest likelihood of experiencing loneliness. Some suggest that this may be due to the use of social media and/or having experienced social isolation during the COVID-19 pandemic. A survey conducted by the Henry J. Kaiser Family Foundation, Association for Advancement of Retired People, and Cigna noted that the prevalence of loneliness among >65 years of age ranges between 22% and 47% in the United States.

Social Connection Leads to Improved Cognitive Function

On the other hand, having a genuine social connection can lead to improved cognitive function. A 2022 Lancet commentary suggests that engaging in social activities may promote the use of neural pathway that protects against age-related neurodegenerative effects and life stressors. Another 2021 study suggests that “social connectivity may increase cognitive reserve, improve resiliency, and promote neuronal networks.”

Ways to Get Deep Social Connection to Boost Cognitive Function

So what are some ways that we can stay connected with others to have a higher-quality life, including improved cognitive function? Here are some suggestions:

  1. Reconnecting with Old FriendsKelly Bilodeau suggests that because old friends have shared past experiences, they are more likely to reconnect with you. You can try reconnecting with your friends you’ve lost touch with through social media, email, or text messages. A 2022 study suggests that unexpected emails to reconnect friendships are appreciated.
  2. Think about Why You Want to Reach Out: Knowing why we reach out can help us be authentic and manage our expectations. Think about whether you can be vulnerable and honest with the person if you are prepared to share your sensitive information, given the history of your past relationship, and have an idea of what you hope to get out of the rekindling of the relationship.
  3. Prioritize the Quality of the Relationship, Not the Quantity: A 2021 study suggests that having stressful relationships can lead to more harmful effects on your health than social isolation. Robert Waldinger also mentions that having a long-term relationship with someone you don’t connect with can have more harmful effects than being alone. Think about what kind of traits of a person you connect with and reach out for connections.
  4. Participate in Sports, Social Clubs, or Group Activities: Having a shared activity that you and others enjoy will help you connect with others better! A 2022 study suggests that experiencing generalized shared reality helps build a solid social connection.

Remember, not only do social interactions in persons help improve your feeling of connectedness, but also electronically reaching out to people alleviates the sense of loneliness. A 2021 study suggests that electronically connecting with others helped prevent mental illnesses such as depression. during COVID-19 pandemic.

Conclusion

There is a high prevalence of social isolation and loneliness, exacerbated by inefficient use of social media and COVID-19. Proactively engaging in activities to build/rebuild relationships can protect against the degenerative effects of loneliness on cognitive function. We highlighted a few simple activities we can engage in to build high-quality relationships. We hope this blog has encouraged you to build your social connections for improved quality of life!

How to Improve Cognitive Level

While many people resign to the fact that cognitive function level declines with age, there are small changes in daily life we can do to reduce its effect. These lifestyle changes will not only improve your cognitive function level but also reduce the likelihood of dementia and Alzheimer’s disease. This post will pinpoint small changes we can embrace to improve our cognitive level.

Why Do We Forget As We Age?

Anyone who has looked for where they had put their keys will be familiar with how easily we can forget things. Older people tend to experience this forgetfulness much more frequently. So why do we forget as we age?

We forget with the reduction of neurons, a major type of brain cells. Although we form millions of neurons in the early years of life, it is said that we start to lose them in our 30s and 40s. A reason why the number of neurons decreases as we age could be because of reduced blood flow to the brain. This may lead to changes in chemicals in the brain, such as reduced epinephrine or blood glucose. Shrinkage of the hippocampus, a brain region that plays an important role in learning and memory, may lead to forgetfulness.

What Is The Difference Between Normal Aging And Neurodegenerative Disease?

Once we start noticing forgetfulness, we may begin to have this worrying thought: “What if I have dementia?”

Memory loss of normal aging involves infrequent forgetfulness. Perhaps once in a while, you will forget about a meeting, a bill payment, or a person’s name. But severe memory loss that makes it difficult to do everyday things like driving, being confused with time, people, and places, or finding your way home, might be a good indication for you to start planning a visit to your doctor.

If you suspect yourself of having a neurodegenerative disease, talk to your doctor. If you are aged over 65 years old and had Medicare Part B for longer than 12 months, you may be eligible for an Annual Wellness Visit to develop a free personalized plan to help prevent dementia. Your doctor may be able to assess your cognitive level with questionnaires like Mini-Mental State Examination.

Such memory-related questionnaires can help differentiate between different stages of dementia. Mild Cognitive Impairment is the stage between the expected decline in memory due to normal aging and the more serious decline due onset of dementia.

What Is My Chance Of Dementia?

Measuring the prevalence of dementia is difficult to measure, especially since the early onset of cognitive impairment is difficult to differentiate from memory loss from normal aging.

With increasing age, the chance of having dementia increases. In 2019, approximately 2% of those aged 70-75 years old had dementia, while 27.7% of individuals aged more than 90 years old had dementia.

There are conditions and activities that may lead to a higher chance of memory loss and neurodegenerative diseases. Excessive drinking of alcohol, smoking cigarettes, and having depression may lead to memory loss. Having chronic illnesses such as diabetes, hypertension, high cholesterol level, and depression may lead to an increased likelihood of dementia. Even hearing impairment could increase the likelihood of cognitive impairment.

What Can I Do To Improve My Cognition?

  • Getting enough daily sleep (7-8 hours) is recommended to improve your cognitive function level.
  • A healthy diet, such as eating fruits that have a lot of antioxidants and omega-3-rich foods such as fatty fish and walnuts can improve brain health.
  • Regular aerobic physical exercises, such as tai chi and walking, for 150 minutes each week is recommended.
  • Social engaging activities, such as volunteering or hobbies, that make you happy interacting with others can have protective effects by improving memory and self-esteem.
  • Journaling and creative writing have been shown to improve the quality of life and well-being of older adults.
  • Relaxation techniques, such as meditation or yoga, can help you reduce stress levels, blood pressure levels, and muscle tension, which can help improve your memory function.

Summary

There’s no worry if you are experiencing memory loss. If it is infrequent, it may be a temporary event. However, if you would like to proactively increase your cognitive level and also prevent the later chances of having neurodegenerative disease, consider taking the lifestyle change actions recommended above. With small incremental efforts each day, you can find tremendous improvement in your quality of life.
