more than doubled, rising from 20.2 million in 1990 to 43.8 million in 2016.The most common form of dementia is Alzheimer’s disease, which accounts for 60-70% of all cases.
As populations age, the prevalence of Alzheimer’s and other forms of dementia is expected to continue rising. Currently, once symptoms occur, they cannot be reversed.
With this in mind, researchers are exploring ways to diagnose the condition years or even decades before it develops, and find drugs to prevent its progress.One promising biomarker of Alzheimer’s is a molecule that circulates in the blood, known as asymmetric dimethylarginine (ADMA).
