A recent study involving nearly 7,000 British civil servants revealed that the human brain functions will decline after entering the age of 45 years. These findings argue well as previous research that says that the decreased brain function at the age of 60 years.
Dr. Michael Merzenich, professor emeritus from the University of California, San Francisco United States, said the decline in brain function tends to be slower in women than men due to hormonal differences. But if a woman has been through the menopause, will gradually slow the cognitive decline is equivalent to a man entered the age of 65 years, says Merzenich.
