A new study found significant improvement in cognitive functions in healthy older adults following 6 months of treatment with growth hormone releasing hormone (GHRH). According to the investigators, this is the first clear evidence that GHRH treatment improves cognitive performance in healthy older men and women, and may also hold promise as potential treatment for individuals with mild cognitive impairment (MCI) or Alzheimer's disease (AD).
