Strategies to preserve brain health – AHA

Life’s Simple 7 focuses on seven lifestyle targets to achieve ideal cardiovascular health:

managing blood pressure
maintaining healthy cholesterol levels
reducing blood sugar
increasing physical activity
eating a healthy diet
maintaining a healthy weight
not smoking

The new statement suggests primary care professionals also consider assessing additional risk factors to address cognitive health. The six risk factors to consider along with Life’s Simple 7 that have an impact on optimal brain health are:

depression
social isolation
excessive alcohol use
sleep disorders
less education
hearing loss

“Scientists are learning more about how to prevent cognitive decline before changes to the brain have begun. We have compiled the latest research and found Life’s Simple 7 plus other factors like sleep, mental health and education are a more comprehensive lifestyle strategy that optimizes brain health in addition to cardiovascular health,” said Lazar, who is also a professor of neurology and neurobiology at UAB.

The statement uses cognition to define brain health, referring to the spectrum of intellectual-related activities, such as memory, thinking, reasoning, communication and problem solving, that enables people to thrive and navigate the world on an everyday basis. The ability to think, solve problems, remember, perceive and communicate is crucial to successful living; their loss can lead to helplessness and dependency.

Lazar says that five components of Life’s Simple 7 have formal screening tools in place that will aid in early recognition of cognitive decline. The other two, diet and physical activity, have guidelines already in place to aid in their adoption.

“Studies have shown that these domains are impacted by factors that are within our control to change,” said Virginia Howard, Ph.D., co-chair of the statement writing group and Distinguished Professor in the Department of Epidemiology at the School of Public Health at UAB. “Prevention and mitigation are important because, once people have impaired cognition, the current treatment options are very limited.”

The authors say that screening and observation need to begin at an early age. A growing body of evidence suggests that making changes in early adulthood can have a significant effect on cognitive decline in older age.

“The time when we need to pay attention to these factors is sooner than we thought,” Lazar said. “Now we understand that attention to these factors even as young as the 30s can make a major difference in the onset of cognitive decline.”

Howard says access to primary care is a hurdle to be addressed, as an estimated 15 percent of American adults still lack health insurance, and 25 percent of Americans do not have a source of primary care.

“The need for more practitioners in the primary care fields will become even more acute as the population ages,” Howard said. “Improved access, more clinicians, better practice models and improved reimbursement will help integrate these preventive measures into daily primary care practice, with the goal of preventing cognitive decline.”

“

Advanced practice practitioners could be vitally important in this effort, along with the use of new technology such as telehealth and apps to help with reminders and motivation to engage in positive behaviors,” Lazar said. “For example, many people already wear a device on their wrist for this purpose. It’s about maintaining our quality of life as we get older.”

Lazar noted the leadership role of UAB in the effort, as he and Howard served as leaders of the AHA writing group. Howard pointed to the close collaborative relationship between the university’s School of Medicine and School of Public Health.

“Alabama is an at-risk state, with a large medically underserved population, positioning UAB to be a real leader in this field,” she said. “We have the tools, the incentive and the will to make a difference.”

Lazar called this work one of the most important efforts that he has undertaken in his career.

“This can be life-changing,” he said. “This is a national health care problem that affects all people, with a particular emphasis on the medically underserved. It will require a combined effort from all of us, including the general public, medical community and policymakers; but we know what we need to accomplish, we know the steps we need to take, and we know what will happen if we succeed.”
