Neighborhood Design Help Seniors Maintain Cognitive Health

A neighborhood’s “walkability” can be a key factor for maintaining physical and cognitive health among older adults.

Researchers from the University of Kansas presented evidence at the annual meeting of the Gerontological Society of America that neighborhoods which motivate walking can stave off cognitive decline in older adults.

“People can walk either to get somewhere or for leisure,” said Amber Watts, Ph.D., an assistant professor of clinical psychology.

“Depending on which type of walking you’re interested in, a neighborhood might have different characteristics,” she said.

“Features of a neighborhood that encourage walking for transportation require having someplace worth walking to, like neighbors’ houses, stores, and parks.”

Watts said neighborhoods that inspire walking for leisure also are full of pleasant things to look at, like walking trails or shade provided by trees. Also, such neighborhoods should make people feel secure on foot.

“For older adults, safety is a key issue in walkability,” she said. “That includes things like traffic lights that give ample time to cross, sidewalks that are in good repair, and benches to stop and rest.”

The researcher judged walkability using geographic information systems — essentially maps that measure and analyze spatial data.

“GIS data can tell us about roads, sidewalks, elevation, terrain, distances between locations, and a variety of other pieces of information,” Watts said.

“We then use a process called Space Syntax to measure these features, including the number of intersections, distances between places, or connections between a person’s home and other possible destinations they might walk to.

We’re also interested in how complicated a route is to get from one place to another. For example, is it a straight line from point A to point B, or does it require a lot of turns to get there?”

Watts said easy-to-walk communities resulted in better outcomes both for physical health — such as lower body mass and blood pressure — and cognition (such as better memory) in the people she tracked.

Watts compared 25 individuals with mild Alzheimer’s disease and 39 older adults without cognitive impairment.

She believes that older adults, health care professionals, caregivers, architects, and urban planners could benefit from the findings.

Researchers used the space syntax data to estimate a “walkability score” for subjects’ home addresses. Then they estimated the relationship between people’s neighborhood scores and their performance on cognitive tests over two year.

Scientists controlled for issues including age, gender, education, and wealth, which might influence people’s cognitive scores independently of neighborhood characteristics.

Some study results were surprising as researchers discovered intricate community layouts appeared to help keep cognition sharp, rather than being a source of confusion.

“There seems to be a component of a person’s mental representation of the spatial environment, for example, the ability to picture the streets like a mental map,” Watts said.

“Complex environments may require more complex mental processes to navigate. Our findings suggest that people with neighborhoods that require more mental complexity actually experience less decline in their mental functioning over time.”

Watts said that older adults, just like all people, tend to choose the easiest available route or the path of least resistance. “If there is an elevator immediately available, why would we choose the stairs?” she said.

“When the environment presents challenges that are reasonable and within a person’s ability level, it keeps our bodies and minds healthy,” Watts said.

“We need that stimulation. With regard to the complexity of neighborhood street layouts — for example, the number of turns required getting from point A to point B — our results demonstrate that more complex neighborhoods are associated with preserved cognitive performance over time.

“We think this may be because mental challenges are good for us. They help keep us active and working at that optimal level instead of choosing the path of least resistance.”

Cognitive testing of the research subjects focused on three categories: attention, or mentally rearranging patterns of letters and numbers; verbal memory, or recalling words immediately and after a delay; and mental status, a screening test for symptoms of dementia.

The work builds on Watts’ longstanding interest in health behaviors, prevention strategies, and bio-behavioral processes associated with cognitive decline and dementia.

“I’ve always been interested in why people choose to engage in healthy behaviors or not,” she said.

“I had been very focused around issues of the individual until I met and started working with architects who study how the physical world around us influences our choices. I found that fascinating, and I wanted to incorporate that into my work about health behaviors.”
