Researchers at Murdoch University’s Center for Healthy Aging found that physical activity can offset some of the negative effects of insufficient sleep on memory and thinking. The results of the study were published in the journal Behavioral Brain Research.
The study included 349 elderly people, approximately 73 years old. The scientists tested their thinking skills and memory, and tested the participants’ brains for the presence of the toxic brain protein beta-amyloid, an early sign of Alzheimer’s disease.
Among the participants, poor sleep was generally associated with poorer memory and thinking skills. However, brain function was less impaired in more physically active people with sleep disorders. Additionally, adequate sleep and physical activity have been associated with lower levels of beta-amyloid in the brain.
“Overall, our results suggest that physical activity may offset some of the negative effects of poor sleep on memory and thinking in older people. However, due to the novelty of this study, more testing is needed to confirm our findings,” he said.
Alzheimer’s disease is the most common form of senile dementia. It usually takes years or even decades to develop. It is believed that a healthy diet, avoidance of bad habits, and adequate physical activity can reduce the likelihood of developing Alzheimer’s disease or delay the onset of symptoms.
ancient scientists discoveredthat high muscle mass may protect against Alzheimer’s disease.
