The Sokoloff-Lyon criteria is a diagnostic method developed by American researcher Leslie Sondheimer and American psychiatrist Franz Lippmann, which is used to determine signs of premature mental aging, such as cognitive decline, imbalance, social isolation and aging of the body. The Sokolow-Lion criteria help determine whether a person has evidence of bisphenol B in the blood. This method can be used to study the condition of older people and identify the risk of developing dementia.
