Exercise and cognitive training may have a positive impact on seniors with mild cognitive impairment (MCI), according to a study published in JAMA Network Open.
The study, conducted by researchers at the Gait and Brain Lab in Ontario, Canada, involved 175 older adults with MCI. The participants were divided into different intervention groups, including aerobic-resistance exercises, computerized cognitive training, and vitamin D supplementation. The results showed that those who participated in aerobic-resistance exercises with cognitive training experienced a significant improvement in cognition, as measured by the Alzheimer Disease Assessment Scale Cognitive 13 (ADAS-Cog-13) score. On the other hand, vitamin D supplementation did not show a significant effect on cognition. This multidomain intervention may potentially delay the onset of dementia in individuals with MCI.
The Bottom Line:
A combination of aerobic-resistance exercises and cognitive training can improve cognition in older adults with mild cognitive impairment, potentially delaying the onset of dementia.
Exercise Plus Cognitive Training: A Winning Combination for Seniors with Mild Cognitive Impairment
Mild cognitive impairment (MCI) is a condition characterized by a decline in cognitive abilities that is greater than expected for an individual’s age and education level but does not interfere significantly with their daily functioning. It is often considered a precursor to dementia. In recent years, researchers have been exploring various interventions that may help slow down the progression of MCI and delay the onset of dementia. This study focused on the combined effects of aerobic-resistance exercises and cognitive training in individuals with MCI.
The study involved 175 older adults, aged 65 to 84 years, who were diagnosed with MCI. The participants were divided into different intervention groups, including:
1. Aerobic-Resistance Exercises: This group engaged in a combination of aerobic exercises, such as walking or cycling, and resistance exercises, such as weight lifting or using resistance bands. This type of exercise has been shown to have many benefits for overall health and fitness.
2. Cognitive Training: This group participated in computerized cognitive training programs that targeted various cognitive functions, including memory, attention, and problem-solving. These programs typically involve engaging in mental exercises and games.
3. Vitamin D Supplementation: This group received vitamin D supplementation, as previous research has suggested that a deficiency in vitamin D may be linked to cognitive decline.
The study found that the participants in the active intervention arms, which included aerobic-resistance exercises, showed a significant improvement in cognition compared to the control group. The addition of cognitive training to the exercise regimen also resulted in a further improvement in cognition. However, vitamin D supplementation did not have a significant effect on cognition.
The findings of this study suggest that a combination of aerobic-resistance exercises and cognitive training may be beneficial for individuals with MCI. These interventions target both physical and cognitive health, potentially delaying the onset of dementia. It is important to note that the results were not consistent across all outcomes measured, indicating the need for further research in this area.
Key Points:
– Aerobic-resistance exercises combined with cognitive training can improve cognition in individuals with mild cognitive impairment (MCI).
– Adding cognitive training to an exercise regimen may lead to further improvement in cognition compared to exercise alone.
– Vitamin D supplementation did not have a significant effect on cognition in this study.
– This multidomain intervention has the potential to delay the onset of dementia in individuals with MCI.
