China has world's fastest rise in dementia with up to 115 million cases forecast by 2050
In 1990 the country had about 4 million patients with
dementia , a number that rose to 17 million by 2021 and is projected to reach 115 million by 2050, according to the research published in PLOS One earlier this month.
The study did not highlight a specific reason for this increase, but the country is already grappling with a range of challenges caused by its rapidly ageing population a
nd this trend threatens to compound the problem
'Alzheimer's and other dementias (ADD) are one of the diseases with the heaviest global disease burden. The disease burden of ADD in China and globally has increased year by year from 1990 to 2021,' said co-authors Siyu Liu and Geng Daoying, from Fudan University.
Geng's research team used data from the Global Burden of Disease database – a free resource backed by international bodies such as the World Health Organization – to collect and analyse the incidence and potential risk factors of dementia in individuals aged 40 and over from 204 countries and regions.
They found that the incidence, prevalence and mortality rates of dementia cases had doubled globally between 1990 and 2021, but over the same period the number of cases rose threefold in China.

Mainland Chinese market for weight loss and diabetes drugs to soon be more crowded: report
Competition in the mainland Chinese market for diabetes and weight loss drugs is set to intensify as more than 60 late-stage drug candidates are undergoing clinical trials, according to a recent report. Up to 20 biosimilar or generic copies will vie for market share and add pricing pressure after Denmark-based Novo Nordisk's semaglutide product loses patent protection in China next year, according to Boston-based global consultancy L.E.K. Consulting. Novo Nordisk's patent will expire in 2031 in Japan and Europe and 2032 in the US, according to its latest annual report. 'The landscape in China is expected to become even more competitive than in developed markets, where the GLP-1 category is primarily dominated by leading multinational pharmaceutical companies,' said Helen Chen, L.E.K.'s global healthcare and life sciences co-head, in a report on May 15. GLP-1 drugs mimic natural hormones, which signal the pancreas to release more insulin when blood-sugar levels are high, and also support weight loss by slowing digestion and reducing appetite. 04:12 One reporter's weight-loss journey and what a 'healthy body' means to him One reporter's weight-loss journey and what a 'healthy body' means to him Driven by sales growth of semaglutide, Novo Nordisk became the 10th largest drug company in the world in terms of revenue. London-based consultancy Evaluate said the firm's revenue rose 25 per cent to US$42.1 billion last year.

China boosts research of Southeast Asian populations overlooked in Human Genome Project
For more than two decades, the Human Genome Project (HGP) – a landmark scientific endeavour led by Western nations – mapped humanity's genetic blueprint, yet the rich diversity of Southeast Asia was overlooked. Despite being home to nearly 300 million people, including the world's largest indigenous population, mainland Southeast Asia (MSEA) contributed a mere 1.57 per cent to global genomic databases, with most data derived from diaspora communities rather than local populations. Chinese researchers say they now aim to rectify the omission. Scientists from the Kunming Institute of Zoology, an affiliate of the Chinese Academy of Sciences, have spearheaded a decade-long collaboration with 34 Southeast Asian research teams, culminating in the first comprehensive genomic atlas of the region – the SEA3K data set – which was published in Nature on May 14. 02:43 Nobel Medicine Prize awarded to US duo for 'fundamentally important' discovery of microRNA Nobel Medicine Prize awarded to US duo for 'fundamentally important' discovery of microRNA The study revealed striking insights, including that MSEA populations harbour unique genetic adaptations to tropical challenges as well as distinct Denisovan ancestry linked to Russia's far east. Before China took a role in the research, fewer than 200 indigenous genomes from MSEA existed in global databases, with neighbouring India contributing most via Southeast Asian diaspora samples, according to the paper. Even city state Singapore, a regional sequencing hub, accounted for 92 per cent of the region's limited data, leaving Cambodia, Laos, Myanmar, Thailand and Vietnam virtually invisible in the genomic era. 'For over a decade, we conducted fieldwork in Southeast Asian rainforests, adhering to local ethical protocols, fostering community engagement and documenting indigenous cultural and linguistic contexts,' corresponding author Su Bing said in an interview with China Science Daily on May 19. Researchers collected samples from Southeast Asian populations covering six countries, five prominent language families and 30 ethnic languages. They completed genome sequencing for 3,023 cases, including 40 high-accuracy long-read sequencing data.

Korean influencer suffers horrific bruises from health injection, wins case after 4 years
A South Korean influencer has won a four-year legal battle against a clinic after a so-called 'health injection' left her with horrific bruising all over her body. Advertisement The woman has drawn widespread support online and reignited public criticism of the way some clinics operate. The influencer, known online as Aori, is a former model with 762,000 followers online. Her channel focuses on fashion, lifestyle, and food. In 2021, she posted photos showing severe bruising across her body, revealing that the injuries were caused by a so-called health injection. She said that she had initially sought treatment to improve her overall health and reshape her body. The influencer, who is known online as Aori, has hundreds of thousands of followers on social media. Photo: Instagram/@minyoung_aori However, during a consultation, the clinic strongly encouraged her to undergo a 'health injection,' claiming she had a 'poor physical condition' and a low chance of getting pregnant.
