Research findings reveal that as much as 40% of globally prevalent dementia cases may be associated with lifestyle factors, providing an opportunity to alter this reality. Hobbies are considered fundamental elements that can help sharpen the mind and strengthen memory, thereby reducing the risk of developing dementia.
Recent studies aim to understand why hobbies are beneficial for the brain and which activities promote brain health. The Lancet Commission on Dementia Prevention compiled data from multiple studies worldwide and identified 14 modifiable risk factors for dementia that can be addressed at various life stages. The results show that avoiding or minimizing these factors decreases the likelihood of developing dementia.
Details of the Findings
According to researchers, the 14 factors include: low education in early stages, hearing impairment, lack of physical activity, obesity, diabetes, high cholesterol, high blood pressure, smoking, excessive alcohol consumption, untreated vision impairment, air pollution, traumatic brain injuries, depression, and social isolation. Researchers explain these findings using the term "cognitive reserve," which means that education and activities that stimulate the mind contribute to creating more neural connections in the brain.
Studies indicate that individuals with high cognitive reserves have better abilities to cope with age-related changes or brain diseases. Furthermore, studies have shown that hobbies and recreational activities enhance this cognitive reserve.
Context and Background
Researchers categorized activities into three groups: physical, such as walking; cognitive, like solving puzzles; and social, such as joining a club. The findings demonstrated that all these activities are associated with a reduced risk of dementia. However, is there a single hobby that can be deemed "magical"? Current research suggests that it is not that simple.
A large-scale Japanese study that followed over 22 thousand individuals without dementia for 11 years revealed that those who engaged in at least one hobby during middle age were 19% less likely to develop debilitating dementia. Those who pursued multiple hobbies achieved even better results, with a 23% reduction in risk.
Implications and Effects
An Australian study conducted in 2023 showed that skills in reading, writing, and critical thinking, such as writing and solving puzzles, are linked to a 9% to 11% decrease in dementia risk. Meanwhile, creative activities like knitting and woodworking were associated with a 7% reduction in risk.
Researchers emphasize that choosing the right hobby is not a prerequisite; it is sufficient to select a hobby that one enjoys and can practice regularly. Research indicates that hobbies help reduce the risk of dementia because they combine elements that support brain health, such as cognitive challenge, physical activity, stress reduction, and social interaction.
Impact on the Arab Region
In the Arab region, where dementia rates are rising due to aging and lifestyle factors, hobbies can play a significant role in promoting health awareness. Encouraging communities to engage in physical and social activities can help mitigate risks.
In conclusion, daily hobbies are an effective means of maintaining brain health and reducing the risk of dementia. It is essential for individuals to recognize the importance of selecting activities that suit them and help enhance their mental and physical well-being.
