Even moderate amounts of walking may help protect brain function and slow changes linked to Alzheimer’s disease. New research reveals a modest amount of daily movement may help protect the brain from Alzheimer’s disease, but the apparent benefit does not involve the biological target researchers expected. Using pedometers, researchers followed nearly 300 older adults with [...]

A negative scan does not always mean recurrent prostate cancer is nowhere to be found. Sometimes, the disease may simply be too small or too faint to appear yet. New research suggests that repeating a PSMA PET scan later can reveal cancer that was missed the first time. Among patients with rising prostate-specific antigen (PSA) [...]

Aging appears to alter how key cerebellar neurons fire, with measurable effects on movement and coordination. Aging often brings slower movement, weaker balance, and reduced agility, but the brain changes behind these losses have been difficult to identify. McGill University researchers have now directly linked declining activity in Purkinje cells, an important type of neuron [...]
