Researchers found that semaglutide and tirzepatide were associated with reduced risks of dementia, stroke, and all-cause mortality in patients with type 2 diabetes and obesity.
A new study identified human pegivirus in the brains and blood of patients with Parkinson’s disease, revealing virus-linked immune and gene expression changes that varied by genetic background.
Once used for coughs, ambroxol is being investigated for Parkinson disease dementia. A new trial shows it is safe and biologically active, though cognitive benefits remain unproven.
In a long-term cohort study, researchers found that specific retinal changes—thinner photoreceptor layers and thicker retinal pigment epithelium—were linked to a higher risk of developing amyotrophic lateral sclerosis, suggesting potential noninvasive biomarkers for early detection.
A study of patients with REM sleep behavior disorder found that lower heart rate variability during sleep may indicate early signs of neurodegenerative disease, particularly Parkinson’s.
A large Swiss study found that nighttime heart rate patterns may predict future risk for brain and psychiatric disorders, while traditional sleep structure measures were less informative.
New study reveals that epigenetic age predictions fluctuate significantly throughout the day, emphasizing the need to consider timing in aging assessments.
