Recent research and expert commentary have shed new light on early dementia symptoms, revealing that persistent low mood and anxiety are among the most common initial indicators—appearing well before notable memory loss in some individuals. As highlighted by a leading neurologist in a recent interview, these subtle psychological changes are often dismissed as typical signs of ageing or everyday stress, but they may in fact signal the onset of cognitive decline (GetSurrey; Nottinghamshire Live).

New research and expert commentary highlight that lasting low mood and anxiety can be among the first signs of dementia, sometimes appearing before noticeable memory loss. A leading neurologist notes that these subtle emotional changes are often mistaken for normal aging or everyday stress, yet they may indicate developing cognitive decline. In Thailand, with an aging population and rising dementia expectations, recognizing mood-related symptoms is crucial for early intervention.

Data from international studies show mood disturbances in the early stages of dementia. A 2025 study found a strong link between anxiety and depression and early Alzheimer’s disease, even in individuals with mild cognitive impairment. Research into Lewy body dementia also indicates that neuropsychiatric symptoms like anxiety can precede classic memory problems, underscoring how mood and behavior changes reflect underlying brain changes. According to researchers, these findings encourage clinicians to consider dementia when mood shifts occur alongside subtle cognitive clues.

A new research breakthrough has introduced a blood test capable of detecting tumor-derived cell-free RNA with remarkable sensitivity, potentially revolutionizing the approach to cancer diagnosis and monitoring in Thailand and around the globe. The study, recently highlighted in Medical Xpress, outlines how scientists have developed a test that can identify even minuscule traces of RNA released by cancer cells into the bloodstream, leading to the possibility of earlier and less invasive cancer detection.

A new blood test can detect tumor-derived cell-free RNA with notable sensitivity, potentially transforming cancer diagnosis and monitoring for Thai patients and beyond. Researchers describe a method that identifies tiny traces of RNA released by cancer cells into the bloodstream, opening the door to earlier, less invasive detection.

Cancer remains a leading health challenge in Thailand, where late-stage diagnoses often limit treatment options and worsen outcomes. The test targets fragments of tumor-derived RNA, which carry genetic instructions from DNA to cells, offering a chance to spot cancer at its earliest, most treatable moments.
