Scientists in Japan have discovered a key molecular change behind the brain fog experienced by many long COVID patients. Using advanced brain imaging, they found increased density of AMPA receptors linked to cognitive impairment. The findings, published on October 1, 2025, could lead to new diagnostics and treatments.

Spotlight on tardive dyskinesia and its management

Tardive dyskinesia remains a significant side effect for patients on long-term antipsychotic medications. Recent medical discussions highlight its symptoms, causes, and emerging treatments. Awareness efforts aim to improve early detection and intervention.

Blood test identifies Parkinson's years before symptoms

October 03, 2025 由 AI 报道

Scientists have developed a blood-based test that detects Parkinson's disease up to seven years before the onset of symptoms. The test targets abnormal alpha-synuclein proteins and shows high accuracy in at-risk individuals. This breakthrough could enable earlier treatments to slow disease progression.

Study associates hearing aids with lower dementia risk

A large-scale study using UK Biobank data has found that adults with hearing loss who regularly use hearing aids face a significantly reduced risk of developing dementia. The research, published in The Lancet Healthy Longevity, highlights hearing loss treatment as a potential modifiable factor in dementia prevention. This comes amid growing evidence linking untreated hearing impairment to cognitive decline.
