A new study by American scientists has shown that older people who have cats and dogs show better results when passing cognitive tests, than those without pets.
Scientists believe that pets can improve brain function, especially when it comes to memory. Researchers believe that the aging brain can stay healthy longer, which reduces the risk of developing such a dangerous disease as dementia.
According to the study, the most beneficial effect of the presence of pets on the brain in people over 65 years old, when serious disturbances in the functioning of this organ can appear. Scientists have found that people who own cats or dogs for more than 5 years have better short-term and long-term memory than those who do not have pets.
But scientists warn that this study does not prove a direct link between pet ownership and a reduced risk of dementia. This may be one of the factors that can influence this process, due to constant communication with pets.
At the same time, the study combines previous data that show that having dogs and cats at home is good for human health. If there are no other contraindications, such as allergies. Although these studies are only theories that explain the potential positive impact of pets on the life and health of the human brain, they have not yet been proven.
According to one theory, having a dog, for example, may mean that their owners forced to get up early and move more, and daily movement is strongly associated with brain health.
Another theory suggests that pets bring new bacteria that can improve human gut health. It has already been proven that there is an important link between gastrointestinal health and brain health.
Given the fact that the risk of dementia increases with physical inactivity, when there are cardiovascular diseases, depression and chronic stress, then theoretically home pets can have a positive effect on human health, especially on brain health, scientists say.
Focus has already written that scientists have named the number 1 factor that affects the occurrence of Alzheimer's disease. This disease is the most dangerous manifestation of dementia.
