Parkinson’s disease to surge to 3.15 million worldwide by 2033: Report

Parkinson’s disease is expected to increase to 3.15 million in 2033 from 2.64 million in 2023, at an annual growth rate (AGR) of 1.94 per cent, said a report on Monday.

The report by GlobalData, a data and analytics company, showed the rise in prevalence of diagnosed cases of the progressive brain disorder will specifically be seen in the seven major countries — the US, France, Germany, Italy, Spain, the United Kingdom and Japan.

It showed that the US is predicted to have the highest number of diagnosed prevalent cases of Parkinson's (1.24 million). Italy, with nearly 0.16 million cases, will have the lowest number.

“In 2023, adults aged 60 and older accounted for over 90 per cent of diagnosed prevalent cases of PD, while adults ages 18-39 made up less than 1 per cent. This age distribution aligns with findings showing higher PD prevalence among older populations,” said Rahul N Ravi, senior epidemiologist at GlobalData.

“There is a slight predominance of sex-specific diagnosed prevalent cases favouring men. Differences across the sexes and markets may be mostly attributed to differences in the underlying demographic differences in each market, as well as the significant differences in sex-specific diagnosed prevalence,” he added.

Parkinson’s is an incurable neurodegenerative disease clinically categorised as a movement disorder with prominent motor symptoms, including tremors, rigidity and bradykinesia. It is the second most common chronic progressive neurodegenerative disorder in the elderly, after Alzheimer's disease.

While current treatments provide symptomatic relief, there is no cure available to halt or slow the progression of the disease.
