A new study has provided the strongest evidence yet that a balanced diet, regular exercise, and social activity can improve cognition and slow down memory loss in older adults at risk of dementia. The research, which included 2,100 participants, found significant improvements in cognitive function among those who engaged in regular moderate to high-intensity physical exercise, adhered to a healthy diet, and participated in social activities.
According to Dr. Jessica Langbaum, senior director of research strategy at the Banner Alzheimer’s Institute, the study demonstrates that these interventions can “slow down memory and thinking problems” in adults at risk for cognitive impairment and dementia. The researchers also found that both structured and self-paced interventions showed an effect, with the high-intensity, structured group showing more improvement.
While there are many reasons to be hopeful about tackling dementia, Dr. Langbaum emphasizes the importance of finding scalable solutions that can be implemented in communities. “Interventions like this one are not sustainable for most people,” she notes. However, even self-paced interventions with some guidance showed an effect.
For individuals looking to protect their cognitive function, Dr. Langbaum recommends finding activities they enjoy and sticking to them, whether it’s exercise classes or socializing with others. A balanced diet rich in leafy greens, low in saturated fats, and other nutritious foods is also key. By incorporating these habits into daily life, people can take a proactive approach to reducing their risk of dementia.
