A new modelling study published in The Lancet HIV journal highlights the alarming potential impact of significant reductions in international funding for HIV prevention and treatment programmes. The research estimates that, globally, between 4.4 to 10.8 million additional new HIV infections and 770,000 to 2.9 million HIV-related deaths in children and adults could occur between 2025 and 2030 if funding cuts proposed by the top five donor countries, including the USA and the UK, are not mitigated. The most affected populations will likely be in sub-Saharan Africa, and marginalised groups who are already at a higher risk of acquiring HIV, such as people who inject drugs, sex workers, and men who have sex with men, as well as children.

People living in more disadvantaged neighborhoods may be more likely to develop dementia than people living in neighborhoods with fewer disadvantages, according to a study published on March 26, 2025, online in Neurology^®, the medical journal of the American Academy of Neurology. The study does not prove that neighborhood factors cause dementia; it only shows an association.

People who have early signs of heart problems may also have changes in brain health that can be early signs of dementia, such as loss of brain volume, according to a meta-analysis published on March 26, 2025, online in Neurology^®, the medical journal of the American Academy of Neurology. The meta-analysis does not prove that early heart problems cause loss of brain cells; it only shows an association.
