Dementia is a growing concern in the US, with nearly 7 million Americans aged 65 and older currently living with memory loss. The number of cases is predicted to almost double by 2060, while the amount of available caregivers is expected to decrease. Researchers are now exploring lifestyle factors that could help reduce the risk of developing dementia.
Sleep has been identified as a crucial factor in preventing dementia, but its poorly understood nature makes it difficult to pinpoint the best approach. While sleep apnea, insomnia, and circadian rhythm disorders can increase the risk of Alzheimer’s disease, scientists are trying to differentiate between normal aging processes and pathological issues.
Exercise, on the other hand, has been found to temper the progression of dementia by interrupting inflammatory cell death from necroptosis. Studies have shown that mice with a four-month exercise regimen had less inflammation and cognitive decline than their control group.
Cognitive workouts can also reduce the risk of memory loss. Practicing a foreign language, learning new information, or taking on challenging puzzles can protect neuroplasticity – the ability for neurons to connect, reorganize, and rewire. Socializing and avoiding isolation are also essential in maintaining cognitive health.
Pharmaceuticals such as GLP-1 drugs may also hold promise in treating dementia. Researchers are currently studying whether these weight-loss medications could be used to slow a person’s digestion and drive to eat, potentially reducing the risk of memory loss.
While more research is needed, experts emphasize that taking brain health seriously through proper sleep, exercise, and socialization can make a significant difference. It’s never too late to start making healthy lifestyle choices, and small actions in our daily lives may have a beneficial impact.
