People who challenge themselves intellectually by writing, reading, doing puzzles and even video gaming may significantly reduce their risk of developing the Alzheimer's.



A new US study provided more evidence suggesting that a lifetime of regular mental or cognitive stimulation is associated with a lower risk of dementia.

Previous findings have suggested that people with higher education, who are mentally active, build up brain reserves that allow them to stay sharp even if deposits of the destructive protein called beta-amyloid, which is a major clinical hallmark of the Alzheimer's disease, forms in their brains.

The new brain study carried out by researchers at the University of California (UC), Berkeley, disclosed that people who engaged in regular cognitively stimulating activities had fewer deposits of beta-amyloid.

During the test, scientists compared brain scans of 65 healthy people with an average age of about 76 with 10 patients suffering from the Alzheimer's and 11 young people whose average age was 25.

Dr. William Jagust and his colleagues also found that the individuals, who were engaged in brain-stimulating activities, particularly the young and middle-aged, had the least amount of beta-amyloid.

Moreover, the older adults who reported the most activity had amyloid levels similar to those of young individuals, while those who engaged in the least number of such activities had amyloid levels similar to the patients suffering from the Alzheimer's, according to the article published in the Archives of Neurology.

“This study suggests that not only does it reduce your risk of Alzheimer's disease, but it may affect the pathological process itself,” Jagust said.

“The environment may affect the amount of amyloid that's deposited,” he added. “This kind of lifetime cognitive activity may make people's brains more efficient. And if your brain is functioning better, it's possible that would result in producing less of this amyloid.”

The scientists concluded that a lifestyle including healthy diet and high physical and mental activity can have a profound effect in preventing the Alzheimer's disease.
