What can we learn from the resilience of senior citizens? A lot can be learned from older generations whose wisdom has been shaped by life’s challenges. See highlights below or read the full article in Psychiatric Times here.

Senior citizens sit at the center of life’s oldest paradox. For many, the closer they come to death, the more their emotional well-being seems to increase. After a lifetime of losing loved ones, suffering defeats, and experiencing physical decline, older adults still manage to take life’s punches in stride.  

Resilience with aging is what gives seniors an edge. How they have adapted to the aging process speaks to their incredible resilience. And it begs the question: What can the rest of us learn from them? 

The Neurobiology of Resilience

Resilience is the ability to quickly recover from stress, whether physical, mental, or emotional. 

Efforts by neuroscience to study why some people are more resilient than others have generally led to elusive answers. For example, a study observed brain images of people who had suffered abuse as children. The intent was to compare brain changes between those who went on to develop psychopathology as adults and those who developed resilience.1 Surprisingly, brain changes associated with maltreatment were noticed equally in both groups of people, whether or not they exhibited psychiatric symptoms. The authors speculated that there may be other molecular alterations or neurobiological changes that helped them adapt to stress.1 

Resilience is thought to involve 3 main brain regions: the prefrontal cortex, the hippocampus, and the amygdala. Research indicates that resilient people have greater connectivity between areas of the prefrontal cortex to the areas of the brain linked to emotions. Their hippocampi and amygdalae are less stimulated.2 

The prefrontal cortex is involved in decision-making and emotional control. Activity in the orbitofrontal network especially plays a role, particularly as it involves reward-related memories. One study suggested that activating this system can improve the body’s stress response and lead to greater psychological resilience.3 

In the hippocampus, gray and white matter volume is larger in resilient adults, with more connectivity between the limbic system and central executive network.4 

As part of the brain’s limbic system, the amygdala plays a huge role in decision-making by helping us process information and rewards, assess threats, and regulate emotions.5 It also ties emotions into certain memories. Resilience is higher when there is less connectivity between the amygdala nuclei and the ventral default-mode network.5 

Resilience involves several neurotransmitters. These include norepinephrine, neuropeptide Y, galanin, corticotropin-releasing hormone, dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEA-S), dopamine, serotonin, abrineurin (BDNF), and allopregnanolone (ALLO).6 

Resilience does not imply a reduction in the response to stress. Rather, more of our brain is involved in adapting to it. As described in 1 article, it is an “active process that implies ongoing adaptive plasticity without external intervention.”7 

Of the mice subjected to stress in 1 study, those with higher levels of resilience engaged 3 times the numbers of genes in their stress response than those with lower resilience.8 Researchers also identified a potassium channel in the Ih channel gene in the brain, which experienced increased activity in the brains of mice with higher resilience.8 

In addition to neurobiology, genetics, and environment, resilience is shaped by other factors including personality, temperament, physical fitness, and social support. All of this can shape how we react to stress and whether we view it as challenging or threatening. Manageable stress can hone and improve our performance, while situations experienced as threatening may significantly impact one’s physical and mental health. 

The Lifecycle of Resilience

With an inheritance range of 33% to 53%, resilience appears to be passed down the generations.9 It is strongest when nurtured at an early age and modeled by parents and caregivers.9  

Because of their fragility, children exposed to higher levels of stress are more susceptible to psychiatric vulnerability, which explains why most mental illnesses are established by age 24.9 The stronger the social network and access to resources at an early age, the better children can stock up on valuable coping skills for adulthood. 

Today’s senior citizens were born at the beginning of an era of unprecedented technology, global connection, and warfare. Those born in the 1920s were the first to enjoy cars, telephones, and movies. Many endured financial insecurities during the Great Depression, and everyone watched as Hitler drew the world into madness and World War II. 

As the United States recovered, the Baby Boomer generation grew up. Born between 1946 and 1964, they would go on to become the largest living adult generation in the United States, influencing everything from the Civil Rights Movement to Social Security reform.10  

They witnessed the Korean and Vietnam wars, the assassination of a president, and a Cold War that hung a shadow of fear over everyday life. The fact that they have seen and experienced so much explains why 90% of seniors have experienced at least 1 traumatic event during their lives.11 It also helps explain their impressive resilience. 

To make it this far in life means seniors have accumulated a lifetime of experiences ranging from challenging to traumatic. Their ability to understand the big picture, see the silver lining, and not sweat the small stuff allows them to feel more content and less psychopathologic than other population groups.12 

Attaining Wisdom

And yet, even with this rich experience, a senior’s resilience can become brittle. Negative perspectives and a resistance to growing old can work against them. They may become overwhelmed with loneliness and sorrow. Losing spouses and friends, seeing family members less and less, and disengaging from activities can be discouraging experiences for anyone. 

What is interesting about the COVID-19 pandemic are indications that many older adults adapted to the isolation of lockdown better than expected, especially in the beginning. Knowing their isolation protected them against COVID-19 contributed to lower anxiety levels among seniors. Technology made it easier than ever to connect with family, strengthening important social bonds. And the confines of social distancing encouraged seniors to value and savor the social connections they did have.13 

Keeping the brain engaged is key to building resilience. By seeking out new challenges and activities, seniors can take their resilience to the next level by developing wisdom. 

Wisdom is more strongly associated with life satisfaction than physical health, finances, socioeconomic status, social involvement, physical environment, or age. Among older hospice patients and nursing home residents, wisdom is more connected to their sense of well-being than it is among other, healthier seniors.14 

One way to understand wisdom is to observe it as a 3-dimensional model that incorporates cognition, reflection, and compassion. The cognitive dimension refers to a person’s need to understand the deeper truths of life, including its positive and negative aspects.  

The reflective dimension paves the way to this understanding by pondering events from many perspectives rather than blaming others or circumstances. The compassionate dimension brings a broad awareness of human nature and suffering that motivates people to help others with sympathy and compassion.14 

The reflective dimension has an especially strong effect on a person’s well-being. This is what allows seniors to be more aware of their feelings and exert greater control over negative emotions, especially those who seek to blame others for their own unhappiness. In short, reflective wisdom allows people to understand and, more importantly, accept their reality.14 

Ultimately, wisdom is what allows seniors to make sense of their paradox. It guides and protects them through the fear and hardship of life, comforting to the very end.
