A large study found that more screen time in late childhood was linked to higher depression scores in early adolescence, with shorter sleep and changes in brain white matter helping explain the connection.
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.
New research links a common metabolic liver condition in older adults to elevated risk of sudden hearing loss, highlighting potential implications for screening and prevention.
A behavioral task asking older adults to recall daily events before sleep was linked to better memory recognition the next morning, showing potential as a low-risk strategy to support cognitive health in aging and early Alzheimer’s disease.
