BEIJING, Aug. 16 (Xinhuanet) --Brain diseases have been on a steady increase in the past two decades and researchers believe they have found a link between these diseases and the environment.

    A report on brain disease in Australia, Canada, France, Germany, Italy, Japan, the Netherlands, Spain, the U.K. and the U.S. , finds that dementia rates have tripled in men and increased by about 90 percent among women over two decades. China Radio International reported Monday.

    Researchers indicate that higher levels of pesticides, industrial effluents, car exhausts, domestic waste and other pollutants are responsible for increases in Alzheimer's disease, Parkinson's disease and motor neurone disease.
