50 million people suffer from dementia worldwide, numbers to triple by 2050. Dementia or the loss of memory will become the principal health hazard in the next century, keeping in view the rising incidences of the disease, a leading neurologist said. Talking to Anadolu Agency, Gokhan Erkol from Koc University Hospital estimated that after every three seconds, someone in the world is getting affected by dementia. Currently 50 million people in the world suffer from the disease. “Almost one out of every two people, between the ages of 85-90 suffers from dementia,” Erkol said. As number of incidences of the disease is doubling after every five years, researchers estimate that by 2050, it will affect a whooping population of 150 million.
