Study Finds Healthy Lifestyle Can Slow Cognitive Decline, Even in People with Dementia

Healthy lifestyle choices such as being physically active, eating well, avoiding smoking, and limiting alcohol consumption may help slow cognitive decline, even in people with dementia, according to a new study published in JAMA Neurology. The study looked at data from participants in the Rush Memory and Aging Project and found that those with healthier lifestyle scores had better cognitive function, regardless of brain pathologies like Alzheimer’s disease.

The researchers discovered that a healthier lifestyle was associated with lower levels of beta-amyloid plaque, a protein linked to Alzheimer’s disease. This suggests that lifestyle factors may have a protective effect on brain function in older adults, even those experiencing cognitive decline.

Experts emphasize the importance of leading a healthy lifestyle for overall brain health, with recommendations such as engaging in physical activity, cognitive stimulation, and maintaining social connections. The study provides further evidence that lifestyle factors play a significant role in maintaining cognitive function and may even help prevent or delay the onset of dementia.

While more research is needed to fully understand how lifestyle choices impact cognition, it is clear that incorporating healthy habits into daily life can have a positive impact on brain health. The study underscores the importance of investing in a healthy lifestyle as a key strategy for maintaining cognitive function as we age.
