New research from University College London has found that jobs that are more mentally demanding are linked to a lower risk of dementia during old age. The survey was based on the analysis of seven studies conducted in the United Kingdom and other countries, involving more than 100,000 people.
According to research by scientists, it was found that professions that demand greater mental stimulation have lesser chances of developing dementia than undemanding professions. The decreased risk of dementia was related to low levels of some compounds, such as SLIT2, CHSTC and AMD proteins. According to the researchers, the relationship was even closer when the dementia in question was Alzheimer’s disease.
A hypothesis developed in the study, therefore, is that the drop in the rates of these proteins may prevent neurons from forming new connections. Thus, long-term brain functioning would be impaired, enabling the development of dementias.
Research can be important in reinforcing the relevance of practicing mental exercises and continuing to challenge the mind. It is already known, for example, that hobbies that stimulate the brain can have many long-term benefits. Now, the new survey reinforces the advantages of living with this type of stimulation of brain activity.
