A protein in the brain could help the memories of those with Alzheimer's disease, a new study has revealed.
Scientists from the Mount Sinai School of Medicine in New York found that when they increased the level of IGF-II in rats, they exhibited much improved long term memory in comparison to those who had not received the protein.
In addition, the effects of this protein were shown to last for several weeks.
The Alzheimer's Society said that the research was promising and indicated that IGF-11 is associated with the health of brain cells.
"However, it is early stage work and more research is now needed to see whether this approach could be the basis of a future treatment for dementia," it added.
This comes after research published in the European Journal of Neurology found that there was a higher risk of the development of dementia with Lewy bodies in those who had also experienced symptoms of adult ADHD.
