Keeping active can slow down the progression of memory loss in people with Alzheimer's disease, a study has shown.
The Nottingham team, led by Dr Marie-Christine Pardon in the School of Biomedical Sciences, has discovered that the stress hormone CRF — or corticotrophin-releasing factor — may have a protective effect on the brain from the memory changes brought on by Alzheimer’s disease.
CRF is most associated with producing stress and is found in high levels in people experiencing some forms of anxiety and depressive diseases. Normal levels of CRF, however, are beneficial to the brain, keeping the mental faculties sharp and aiding the survival of nerve cells. Unsurprisingly then, studies have shown that people with Alzheimer’s disease have a reduced level of CRF.
