Scientists have found exciting evidence that combining diet, exercise, and brain training can really help improve thinking and memory in older adults. A recent study involving over 2,100 sedentary individuals in their 60s and 70s showed that sticking with this routine for two years led to noticeable benefits in mental abilities, almost equivalent to individuals one or two years younger.
Laura Baker, a gerontology expert at Wake Forest University and one of the study’s leaders, said, “These participants are scoring cognitive function levels comparable to those younger than them.” Jessica Langbaum from the Banner Alzheimer’s Institute remarked, “This research indicates we can actually change people’s cognitive trajectories over time.”
These promising results came from the POINT study, shared at the Alzheimer’s Association International Conference and published in the Journal of the American Medical Association. They align with earlier findings, like a smaller study in Finland, that suggested even simple lifestyle changes, such as exercising, could positively influence brain health.
The POINTER study focused on folks aged 60 to 79 who had normal memory but were at higher risk for cognitive decline. Participants had to be sedentary and maintain a less-than-optimal diet. Half of them followed a structured program that included aerobic exercises, a heart-healthy Mediterranean diet, online brain training, social activities, and regular health monitoring. The other half had to create their own eating and exercise plans.
Both groups showed improvements in memory and cognition tests, but the intensive group fared much better. Baker described the adjustments made by participants as “life-changing.” Many adopted new habits due to close coaching and encouragement.
However, translating these habits into broader community practices presents its own challenges. The Alzheimer’s Association is investing an additional $40 million to further implement the findings from the POINTER study. They plan to explore how to effectively motivate individuals, whether through healthcare providers, apps, or other technology.
One key to success is the collaboration of healthcare professionals. Langbaum noted that lifestyle interventions should be treated like medical prescriptions, including efforts to motivate people at risk of dementia.
Encouragingly, as more Americans seek ways to improve their brain health, there’s a growing desire for guidance. Many individuals express concern about cognitive issues in their families, prompting them to seek effective strategies.
For those already living healthily, Langbaum suggests ramping up efforts. If you usually do easy puzzles, try more challenging ones. Engaging in exercise with others can also enhance brain health, as social interactions are known to keep minds youthful.
This study underscores the powerful impact of intentional lifestyle changes on cognitive health as we age. Small adjustments made regularly can lead to significant improvements over time.
