This will become a major health challenge, as the disease will grow by 112% globally by mid-century compared to 2021, the study analyzes.

A neurodegenerative disease that causes the death of neurons in one part of the brain, it limits the brain’s availability of dopamine, a key neurotransmitter for controlling movement.

It is the second most common neurodegenerative disease, behind only Alzheimer’s disease, which currently has no cure.

As part of the study, a team of researchers led by Tao Feng of the Chinese Tiantan Hospital in Beijing carried out, using different estimation models, a projection of what will happen in the coming decades with the disease, taking into account data from 195 countries.

The results show that aging will be the main cause (89%) of the increase in the prevalence of the disease, followed by population growth (20%) and that the greatest increases in the number of cases will occur in East Asian countries, in males and in middle-income nations.

The study details that the countries with the most cases in 2050 are expected to be China, India, the United States, Germany, Brazil, Indonesia, France, Spain, Mexico and the United Kingdom.
