How many physical activity sessions are needed to avoid cognitive deterioration?

  • A study ensures that practicing about 12 sessions could begin to obtain some benefits.

Physical activity has been studied for many years to prevent diseases.

For decades, various investigations have affirmed that leading a less sedentary life has beneficial effects, both in the prevention of neurodegenerative diseases such as dementia and Alzheimer's, as well as for the initial phases of these at the level of cognitive function, they expose from Neurodidact.

For this reason, experts recommend practicing physical exercise at least three times a week and in a moderate way, to protect yourself from neurological damage that leads to cognitive deterioration.

In short, leading a healthy life and staying physically and cognitively active can be highly beneficial in preventing the risk of developing cognitive impairment.

But, many people wonder, what is the necessary amount of physical exercise to prevent cognitive decline?

It is true that physical activity, nutrition and cognitive stimulation activities are good ways to prevent diseases such as Alzheimer's and dementia, but until now it was unknown to what extent.

An international team of researchers has recently studied how many exercise sessions are necessary to prevent cognitive decline in people at risk.  The results have determined that with only about twelve sessions the results can already be noticed.

The study, led by Sylvie Belleville, a psychology professor at the University of Montreal in Canada, and published in the journal Alzheimer's & Dementia: The Journal of the Alzheimer's Association, has shown that only 12 and 14 sessions to observe an improvement in cognition.

 As these experts explain, "until now the number of sessions or doses necessary to obtain an optimal effect was unknown."


How is it possible to determine the necessary dosage of exercise?

Belleville explains that, as in pharmacological studies, it is necessary to "define the optimal dose of treatment necessary to observe the expected effects."  However, in studies of prevention of cognitive decline, it is rarely carried out, since "little information is available to identify this dose".

Thus, the experts focused on one of their objectives: "it is crucial to define an optimal number of treatment sessions", explained the doctor, since "proposing very few sessions will not produce appreciable improvement effects, but too many sessions is not desirable either, since these interventions are expensive both for the individual who follows the treatments, and for the organization that offers them".

To obtain the results, they analyzed 749 participants who received a series of interventions aimed at preventing cognitive decline.  These interventions included dietary advice, physical activity, and cognitive stimulation to improve or maintain physical and cognitive abilities.

According to Belleville, it must also be taken into account that the individuality of the people is very important when determining the optimal dose of treatment.

Therefore, the researchers evaluated the effects of the sessions based on the age, gender, educational level and the cognitive and physical state of each participant.  Subsequently, the relationship between the dose received by each one and their cognitive improvement was analyzed.

The main results of this research show that a beneficial effect can be seen with 12 or 14 sessions of physical exercise, but that there were some participants, such as those with lower levels of education or more risk factors for frailty, who needed some session more to get the benefits.

In short, these experts affirm that it is important to "identify and guide an optimal dose and personalize the treatment for each individual."
