A Blood Test Can Predict Dementia. Trouble Is, There’s No Cure
Nobel prizewinner Koichi Tanaka says the predictive blood test for Alzheimer’s disease he and colleagues spent almost a decade developing is a double-edged sword.
Without medications to stave off the memory-robbing condition, identifying those at risk will do nothing to ease the dementia burden and may fuel anxiety. But used to identify the best patients to enroll in drug studies, the minimally invasive exam could speed the development of therapies for the 152 million people predicted to develop the illness by 2050.

Adopting a healthy lifestyle helps reduce the risk of dementia
New WHO Guidelines recommend specific interventions for reducing the risk of cognitive decline and dementia
14 May 2019 – People can reduce their risk of dementia by getting regular exercise, not smoking, avoiding harmful use of alcohol, controlling their weight, eating a healthy diet, and maintaining healthy blood pressure, cholesterol and blood sugar levels, according to new guidelines issued by the World Health Organization (WHO) today.
“In the next 30 years, the number of people with dementia is expected to triple,” said WHO Director-General Dr Tedros Adhanom Ghebreyesus. “We need to do everything we can to reduce our risk of dementia. The scientific evidence gathered for these Guidelines confirm what we have suspected for some time, that what is good for our heart, is also good for our brain.”
