A new study found that daily multivitamin supplements improved memory, executive function and cognition in older adults. Some age-related cognitive decline is normal, but older adults are also at risk of developing cognitive disorders such as Alzheimer’s disease and other forms of dementia.
Research is ongoing into factors that affect cognitive health and what may help prevent or slow cognitive decline. A new study found that multivitamin and mineral supplements improved memory, executive function and cognition in older adults who took a daily dose. Older adults who experience cognitive decline are at risk for Alzheimer’s disease and other forms of dementia.
Experts are still working to understand the factors that affect cognitive function and what steps people can take to help prevent cognitive decline. A study published in the journal Alzheimer’s and Dementia investigated whether daily intake of multivitamins or cocoa extract affected cognitive function in older adults. Although the authors found no improvements associated with cocoa consumption, they did find that daily multivitamin and mineral supplementation was associated with improved memory and executive function.
Cognitive decline in the elderly
Many people experience some age-related cognitive decline as they age. Reliable source. For example, occasionally forgetting details or misplacing something may become more common with age. However, severe cognitive decline can lead to Alzheimer’s disease and dementia, which involve significant changes in a person’s ability to remember or make decisions that affect their daily life. Although diseases such as Alzheimer’s disease and other forms of dementia are not common with age, people over the age of 65 are at a higher risk of developing these diseases.
Researchers tend to agree that, in general, aging is associated with changes in cognitive function. Perhaps the most discussed change in brain function associated with aging is long-term memory decline, where general memory decline has sometimes been considered part of “normal aging.” Further deterioration is associated with dementia such as Alzheimer’s disease. The work also shows a general decline in working memory (the temporary storage system in our brains that allows us to work with multiple pieces of information) in older adults, as well as relatively greater difficulty multitasking. Experts are still trying to understand the full impact of age-related changes. Research also focuses on preventive measures that seniors can take to improve and maintain their cognitive function.
Multivitamins and cognitive decline
In the study, researchers examined the effects of a daily cocoa extract or multivitamin-mineral (MVM) supplement on cognitive function compared to a placebo. The authors of this study conducted a randomized clinical trial of more than 2,000 adults aged 65 and older. Participants had to meet specific eligibility criteria to participate in the study. For example, they must not have heart attacks or serious illnesses that would prevent them from participating. They also must not be allergic to cocoa products or caffeine.
The researchers established the baseline of participants’ cognitive function at the beginning of the study. They also looked at the participants’ ability to recall events and memories (episodic memory) and their executive function, which is related to concentration and thinking. They reassessed these components every year for three years.
The results of the study show that cocoa extract did not affect cognition. However, multivitamin use was associated with better cognition, executive function, and episodic memory. Participants with cardiovascular disease benefited the most.
The study author explains: “Daily multivitamin supplementation shows potential to improve (or protect) cognitive performance in older adults. However, further work is needed before a general recommendation can be made. Daily multivitamin supplementation has shown a relatively greater benefit in adults with cardiovascular disease. Given that only 10% of our sample (~200 people) reported significant cardiovascular events (eg, stent placement, congestive heart failure, angioplasty) at the time they entered the study, this result needs to be replicated in a larger sample. including more people. with serious cardiovascular disease. »
The positive correlation between multivitamin use and cognition compared to placebo is notable, and although the overall multivitamin data are less supportive of a clear net benefit in the general population, they do support the idea. micronutrients may benefit long-term brain health in aging populations, particularly those with pre-existing vascular disease. »
