The Six Dimensions of Wellness: Protecting Cognition in Aging
A growing body of evidence shows that wellness, across six interconnected dimensions, may be one of the most powerful tools we have for supporting cognitive health in older adults. Here is what the research says, and how we are designing EngAGE Beverly around it.

When most people think about protecting cognitive health as we age, they think about puzzles. Maybe a daily crossword. Maybe a memory app on a phone. The cultural script around dementia prevention is narrow, individualistic, and according to the evidence, incomplete. The research on what actually protects cognition in older adults paints a far more interesting picture: it is the breadth and depth of someone's engagement with life across multiple dimensions, sustained over time, that appears to matter most.

A 2012 review in the Journal of Holistic Nursing by Strout and Howard synthesized evidence across six dimensions of wellness (occupational, social, intellectual, physical, emotional, and spiritual) and the results were striking. Wellness in even one dimension may protect cognition in aging. Wellness across multiple dimensions appears to compound that protective effect. Critically, strength in one dimension may compensate for weakness in another, meaning that no single program or intervention captures the whole picture (Strout & Howard, 2012).
The original Six Dimensions framework was developed by Dr. Bill Hettler, co-founder of the National Wellness Institute, in 1976. What Strout and Howard contributed nearly four decades later was a careful mapping of the framework onto the gerontological evidence base, translating decades of disparate research findings into a coherent, holistic model for thinking about aging. For anyone designing care or community for older adults, particularly those experiencing memory loss or early cognitive changes, it is a model worth taking seriously.
This is the framework that shapes how we are designing EngAGE Beverly. Below, each of the six dimensions, what the research says, and how we are translating it into the rhythm of an actual day.
Wellness in two or more dimensions appears to protect cognition more than wellness in any single dimension alone, and strength in one dimension may compensate for weakness in another.
Dimension One: Occupational Wellness
The word "occupational" can be misleading. In Hettler's framework, occupational wellness is not about employment in a narrow sense; it is about the contribution of one's unique skills and talents to meaningful work, paid or unpaid, that benefits the well-being of a community. The research is nuanced and important. Karp and colleagues (2009) followed 931 adults aged 75 and older in a population-based longitudinal study and found that those who had worked in complex occupations involving people and data showed stronger cognitive performance in older age than those whose primary work involved things. A separate co-twin study found that higher complexity of work with people was associated with reduced risk of dementia and Alzheimer's disease, independent of age, gender, and education (Andel et al., 2005).
Among adults with fewer years of formal education, those whose work involved self-direction had less risk of cognitive impairment than peers in low-complexity roles. The protective factor, in other words, was not the prestige of the job; it was the genuine engagement of one's mind and judgment in service of something beyond oneself.
In our home: Everyone has a role, and every role contributes to the workings of the morning. The occupational dimension is woven through every gathering at EngAGE Beverly in the form of Montessori-inspired meaningful work: gathering the mail when it arrives, watering the plants, filling the bird feeders, folding cloth napkins for our shared lunch, kneading bread dough that rises during the morning, arranging garden flowers in vases for the table, decorating place cards. These are not crafts or busywork; they are contributions to a household. Our friends know that the meal would not happen, the birds would not be fed, and the table would not be set without them.
Dimension Two: Social Wellness
Social wellness, defined as positive personal and community relationships built on mutual respect, appears in the literature as one of the most consistently protective factors in cognitive aging. Hakansson and colleagues (2009) found in a population-based longitudinal study that adults who lived without a partner at midlife had nearly twice the risk of cognitive impairment in older age compared with those living with a partner; for those who lived alone in both midlife and older age, the risk was three times higher.
Perhaps the most striking finding in this dimension comes from work by Bennett and colleagues (2006), who studied older adults in the Rush Memory and Aging Project. Their longitudinal clinical-pathological study found that even among participants with severe levels of disease pathology in the brain, cognitive performance remained higher when social network sizes were larger, meaning that strong social connection did not just delay cognitive decline; it appeared to help the brain function above what its underlying biology would predict.
In our home: The social dimension shapes everything from arrival rituals (every friend greeted by name) to the shared lunch on Tuesdays, where caregivers join for the final half-hour to build connection across families. On Thursdays, our three daughters are home for homeschool and spend the morning with our friends, layering in genuine intergenerational connection. Eight people maximum at full scale means everyone knows everyone.
Dimension Three: Intellectual Wellness
Intellectual wellness is the commitment to lifelong learning, the continuous, self-directed acquisition and creative use of new skills and ideas. The evidence is robust. Multiple studies have established that twelve or more years of formal education correlates with stronger cognitive performance in older age (Koster et al., 2005; Lievre et al., 2008; Plassman et al., 2007). Formal education, however, is only part of the story, and it is the rest of the story that interests us most.
Gilhooly and colleagues (2007) found that older adults who deliberately engaged in intellectual activities (reading, puzzles, computer games) demonstrated significantly lower levels of cognitive impairment, and that adults perceived intellectual activities as more beneficial than social or physical activities for maintaining cognition. Lachman and colleagues (2010) extended this finding in an important way: people with fewer years of formal education who engaged in intellectually stimulating activities at least once a week showed stronger cognitive performance than those with the same education levels who did not. Intellectual wellness, in other words, can compensate for educational disadvantage, and it is never too late to begin.
In our home: Intellectual wellness anchors our Tuesday morning rhythm through Reading Roundtable, Dr. Cameron Camp's evidence-based group reading methodology designed for adults with memory changes, alongside a Montessori choice station with sorting and matching activities, current-events reading, and puzzles. On Thursdays, our daughters lead Junior Great Books Shared Inquiry, a discussion-based reading practice that invites everyone at the table, regardless of age, to bring their own questions and interpretations to a short story or essay. Our daughters also produce a "Weekly News" as part of their homeschool curriculum and read it aloud with our friends. Both practices build literacy on both sides of the table.
Dimension Four: Physical Wellness
Physical wellness includes both regular movement and healthy nutrition, and the research connecting both to cognitive aging is extensive. Larson and colleagues (2006) followed 1,704 randomly selected adults age 65 and older without cognitive impairment at baseline. Among those who exercised three or more times per week, the incidence rate of dementia was 13 per 1,000 person-years; for those who exercised less than three times per week, it was 19.7 per 1,000 person-years. Middleton and colleagues (2010) followed nearly 10,000 women and found that physical activity at any stage of life was associated with reduced odds of cognitive impairment. Activity in the teenage years showed the strongest protective effect, though women who became active in midlife after sedentary teenage years still showed significantly lower odds of impaired cognition.
On nutrition, Scarmeas and colleagues (2009) studied 1,393 adults across more than a decade and found that those with the highest consumption of healthy foods (fruits, vegetables, legumes, cereals, and fish) demonstrated 28 percent less risk for cognitive decline than those with low consumption. Laitinen and colleagues (2006) found that moderate consumption of polyunsaturated and monounsaturated fats in midlife was associated with decreased risk for dementia, while diets very low in fat or high in saturated fat were associated with increased risk.
In our home: Physical wellness shows up in our morning movement rotation: chair yoga, tai chi, seated dance, partner stretching. On Thursdays in gross motor games: balloon volleyball, cornhole, parachute play, ring toss, and a walk to Hurley Park (less than a block away) for nature gathering. Movement also happens naturally in the rhythm of the home itself. Members move from the kitchen to the dining room to set the table, from the living room to the porch to fill the bird feeders, from the entryway to the kitchen to bring in the mail. This is intentional, but it is not always a structured activity. People with dementia move best when movement has a purpose, and a home that is genuinely lived in offers purpose at every turn. Our shared lunch is simple, home-cooked, and seasonal: recognizable to our friends' generation, easy to chew and swallow when needed, and built around the kinds of foods the research supports.
Dimension Five: Emotional Wellness
Emotional wellness reflects the capacity to acknowledge and manage one's feelings, take responsibility for one's choices, form interdependent relationships built on trust, and approach challenges with stability. The evidence on this dimension is particularly important and underdiscussed. Wilson and colleagues (2007) followed 1,256 older adults for twelve years and found that those high in neuroticism (emotional distress, anxiety, depressive symptoms) were forty-two percent more likely to develop cognitive impairment than peers with low neuroticism. The risk of mild cognitive impairment increased by six percent for each depressive symptom reported.
The flip side is just as compelling. Forstmeier and Maercker (2008), studying 147 community-dwelling adults aged 60 to 94, found that lifetime motivational reserve (the ability to choose among alternative goals and persist toward them) protected cognition in older age, even after controlling for age, education, and intelligence. People with stronger motivational ability and higher psychological well-being demonstrated stronger cognitive performance. Wang and colleagues (2009) added a critical nuance: adults with low neuroticism and high extraversion had the lowest incidence of dementia, and even adults with low neuroticism who lived socially isolated lives showed reduced dementia risk relative to their more anxious peers.
The takeaway is that emotional steadiness is not a personality trait we are stuck with. It can be supported and shaped by environment: by predictability, by warmth, by autonomy, and by genuine relationship.
In our home: Our entire model is designed around predictable rhythm and warm consistency, both of which directly reduce the chronic distress associated with elevated cognitive risk. Our friends arrive to a home that is the same shape it was last week, where the day's choices are theirs. The autonomy preserved by Montessori-based activities supports the kind of motivational reserve that Forstmeier and Maercker identified as protective.
Dimension Six: Spiritual Wellness
Spiritual wellness, in Hettler's framework, is not synonymous with religion, though for many people it includes religious practice. It is the broader capacity to find meaning and purpose in life, to develop a coherent value system, and to feel oneself part of something larger. The research on this dimension may be the most striking of all.
Boyle and colleagues (2010) followed 900 community-dwelling older adults across seven years and found that those with high purpose in life were approximately 2.4 times more likely to remain free of Alzheimer's disease than those with low purpose, and 1.5 times more likely to remain free of mild cognitive impairment. Those with greater purpose declined less rapidly when decline did occur. Coin and colleagues (2010) studied 64 older adults already diagnosed with mild-to-moderate Alzheimer's and followed them across a year; the high-religiosity group maintained cognition while the low-religiosity group declined significantly in cognitive performance and showed increased aberrant motor behavior, irritability, apathy, depression, and aggression.
Purpose, in this body of research, is not abstract. It is the daily, embodied sense that one matters, that what one does has meaning to others, that one's existence is part of a coherent whole.
In our home: The spiritual dimension is the soul of our model, even though we name it least often. Everyone has a role, and every role matters. Every contribution our friends make, to the lunch table, to the bird feeders, to the conversation, to the children's lives, is a visible reminder that they are needed here. When Pops teaches his granddaughter how to tie a knot, when a friend tells the story they have told before about Beverly in 1962, when someone arranges flowers and then sits at the table where those flowers are now the centerpiece, purpose is not abstract. It is the morning itself.
Why the Holistic Model Matters
What makes the Six Dimensions framework so useful is that it captures something simpler approaches miss: the dimensions interact. Strout and Howard's review surfaced the consistent finding that wellness in two or more dimensions appears to protect cognition more than wellness in any single dimension alone. They also highlighted the more surprising finding that wellness in one dimension may compensate for weakness in another.
Adults with no social networks but low neurotic personalities had less risk for cognitive impairment than adults with no social networks and high neuroticism (Wang et al., 2009). Adults with fewer years of formal education who held complex, self-directed occupations showed less risk than peers with the same education in low-complexity roles (Karp et al., 2009). Adults who took up exercise in midlife after sedentary teenage years still gained meaningful cognitive protection (Middleton et al., 2010).
If wellness in one dimension can compensate for weakness in another, and if multiple dimensions compound their effects, then care models that focus narrowly, only on physical activity, or only on cognitive games, or only on social activity, leave protective resources on the table. A care model that addresses several dimensions simultaneously, in a sustained way, offers something fundamentally different.
This is what we are building at EngAGE Beverly. Not a series of activities. A genuinely holistic environment in which every morning intentionally addresses occupational, social, intellectual, physical, emotional, and spiritual dimensions of wellness.
What This Means for Our Work
There is a tendency, in well-meaning conversations about dementia care, to imply that any meaningful intervention has to come from a clinician, a pharmaceutical, or a specialized program. The Six Dimensions framework points in a different direction. The protective factors that emerged most consistently in this body of research are: meaningful work, sustained relationships, intellectual engagement, regular movement and good food, emotional steadiness, and a clear sense of purpose. These are not exotic. They are the elements of a well-lived life, and they are what a thoughtful, home-based community can support every single day.
EngAGE Beverly is built on the conviction that this kind of holistic, relationship-centered care is not a luxury or a soft alternative to "real" intervention. It is the intervention. The research is consistent on this point, even if our broader culture has not yet caught up. We are committed to building something that takes the evidence seriously, and that meets older adults, particularly those experiencing memory loss or early cognitive changes, with the dignified, dimensional care the science says works and we all believe they deserve.
