Oxygen4IndiaClimate change is emerging as a serious threat to brain health, with rising temperatures, humidity fluctuations, and environmental factors like dust and sandstorms increasing the risk of stroke. Experts from the World Stroke Organization highlight the growing link between environmental changes and stroke incidence.
Oxygen4IndiaA new study has identified three distinct trajectories of cognitive decline in Alzheimer’s disease—stable, slow decline, and rapid decline—linked to key biomarkers like amyloid and phosphorylated tau. The findings could improve early detection and help predict disease progression in at-risk individuals.
Oxygen4IndiaChanges in the gut microbiome of individuals carrying Parkinson’s risk genes may help predict disease onset earlier, according to new research. The findings suggest that microbial shifts could act as early biological markers, enabling timely diagnosis and improved management of Parkinson’s disease.
Oxygen4IndiaA new study suggests that a blood-based biomarker could help predict a woman’s risk of developing dementia up to 25 years before symptoms appear. Researchers found that higher levels of phosphorylated tau 217 (p-tau217), a protein linked to Alzheimer’s-related brain changes, were strongly associated with future cognitive decline among older women who were cognitively healthy at the start of the study.
