Prefer Reading and Writing Brain Aging

Reading books and playing puzzle has been known to decrease the possibility ofAlzheimer's disease. A recent study may explain why it happened. Apparently these activities to reduce accumulation harmful proteins brain.

In that study senior citizens who confessed to mentally stimulating activities throughout his life has little beta-amyloid deposits, which is typical of proteins that haveAlzheimer's. Findings were irrespective of sex education participants or old.

"The findings suggest that cognitive therapy that stimulates the brain can slow progression this disease, if applied before symptoms appear," said researcherWilliam Jagust, a professor at the University of California, Berkeley's Helen WillsNeuroscience Institute.

Researchers have discovered that Alzheimer's is a complex disease that has morethan one cause. Research was published in journals Archives of Neurology.

Researchers asked 65 healthy adults aged 60 and over mentally to assess how often they engage in activities that sharpen mental abilities such as going to the library, read a book or newspaper and write letters or emails.

Participants were also given tests to assess memory and other mental ability, and receive scan positron emission tomography (PET) using a new compound that was developed to visualize amyloid protein. Brain scan of participants are then comparedwith 10 patients diagnosed with Alzheimer's disease and 11 healthy people in their 20s.

Researchers found a significant between high levels of mental activity during a lifetime with lower levels of PET. Elderly with highest number of lifetime mental activityalso have high levels of amyloid comparable young people. Conversely, adults who reported the lowest level of mental activity have comparable levels of amyloid withAlzheimer's disease patients.

However, researchers say it would not hurt to brain training in later life. Researchers noted that the buildup amyloid can also be influenced by genes and aging. One third of study participants aged 60 years and over have some storage amyloid in their brains, but some of them are still many who can read and write properly.
