A study found that “slowly expanding lesions” in the brain of people with multiple sclerosis show a distinct pattern of microstructural damage, detectable by diffusion MRI, which is strongly linked to disability progression that occurs without relapse. This damage signature, measured as a decline in fractional anisotropy, could serve as a predictor for identifying patients at risk of long-term worsening, helping doctors tailor more aggressive treatments earlier.

Researchers validated the Lumipulse G plasma p-tau217 blood test, showing it can reliably detect Alzheimer’s disease pathology by measuring a specific protein linked to the disease. The test proved to be highly accurate and reproducible, supporting its use as a less invasive and more accessible tool for diagnosing Alzheimer’s in clinical settings.

A new analysis reveals that specific environmental factors, such as weather changes and air pollution, can act as acute triggers for migraine attacks leading to emergency room visits. Understanding these modifiable triggers offers a pathway for individuals to better manage their condition and potentially reduce the frequency of severe migraine episodes requiring urgent care.
