A study using advanced brain scans shows that in Alzheimer’s disease, language problems follow a predictable pattern as the disease’s hallmark tau protein spreads. People first report trouble finding words in the earliest stages, then have measurable difficulty naming objects, and finally experience widespread language impairment in later stages. This provides a clear biological roadmap of how Alzheimer’s progresses, which could help doctors detect and stage the disease much earlier.

A new review clarifies the diagnosis and treatment of POEMS syndrome, a rare disorder that often causes severe nerve damage. The condition is frequently misdiagnosed as a more common nerve disease, but key features like high levels of a protein called VEGF in the blood and specific nerve test results can help doctors identify it correctly. Early and accurate diagnosis is critical because specific treatments, like chemotherapy or stem cell transplants, can prevent permanent nerve damage and significantly improve a patient’s long-term outlook.

A large study in South Korea has mapped out how common three major inflammatory nerve diseases are, finding that multiple sclerosis is the most frequent, followed by neuromyelitis optica spectrum disorder and myelin oligodendrocyte glycoprotein antibody disease. This is the first nationwide data to show the relative proportions of these conditions, which can have similar symptoms but require very different treatments. Understanding their true prevalence helps health systems plan resources and ensures patients get the correct diagnosis faster.

A study on a new oral form of the cancer drug paclitaxel (called DHP107) found it to be as effective as the standard intravenous version for treating a type of advanced breast cancer. The oral pill could offer a major convenience benefit, as it avoids the need for lengthy IV infusions in a clinic and reduces the risk of severe allergic reactions. This represents a significant step toward more patient-friendly cancer treatments that can be taken at home.

Research into a severe newborn gut condition called necrotizing enterocolitis has identified a new potential marker: specific small RNA molecules derived from tRNA are expressed differently in affected infants. These molecules could serve as an early warning signal for the disease, which is currently difficult to predict and diagnose. Finding such a biomarker is a crucial first step toward developing tests to identify at-risk babies and intervene before the condition becomes life-threatening.
