The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Delays in cancer diagnosis persist for young people with certain tumors

A new study, led by experts at the University of Nottingham, has found that young people suffering from certain types of cancer, such as bone tumors, are experiencing lengthy times to diagnosis.

Alzheimer’s blood biomarkers predict faster muscle strength loss in older adults

A large Swedish cohort study found that elevated blood biomarkers associated with Alzheimer’s disease—including p-tau217, p-tau181, neurofilament light chain, and GFAP—predict accelerated muscle strength decline over 12 years in dementia-free older adults. These findings suggest that early identification of Alzheimer’s-related biomarkers could help clinicians intervene sooner to prevent sarcopenia and related adverse outcomes in aging populations.
