Research indicates clues to early detection and prevention of Alzheimer's disease

  • The proportion of cells releasing neuropeptides was significantly lower in Alzheimer’s brains than in healthy brains.
  • Neurons with the most neuropeptide activity—those releasing higher levels and greater diversity of neuropeptides—were disproportionately absent in Alzheimer’s brains.
  • Increased age coincides with decreased neuropeptide activity in the hippocampus of Alzheimer’s brains, affecting an area of the brain that plays a major role in learning and memory.
