Many studies have been performed on different mammals (rats, dogs, humans, …) and have shown that mental stimulation helps fight against the aging of the brain. In both traditional and holistic medicine mental stimulation is carried out as part of specific care for the elderly (for instance to fight against Alzheimer’s), but also for young children, or even infants, to overcome some growth and/or development concerns.
It is known, scientifically and internationally, that the brain becomes and remains active by being regularly used and trained: “use it or lose it”, to quote a famous maxim. What is true for humans is also true for any species with a similar nervous system, including our dogs.
A recent scientific study (Cornell University) analyzed the impact that a stimulating environment can have on mice with cancer: mice that benefited from this enriched environment seem to have been protected against the development of cancer.
