Hippocampal Neurogenesis Life-Long (BBC News / Nature Medicine)

Summary Contrary to popular belief, the creation of new brain cells persists throughout life (in the hippocampus at least); although the rate of neurogenesis may decline with old age, and fall massively in Alzheimer’s Disease. Full Text Link Reference Gallagher, … Continue reading

Memories Lost in Alzheimer’s Disease: Potentially Retrievable? (NHS Choices / Nature)

Summary Research on transgenic mice suggests that memories are not destroyed irretrievably by Alzheimer’s Disease; there appears to be problems recalling these lost memories. Lost memories may be retrievable, under experimental conditions, by exposing “Engram Cells” with bright blue light … Continue reading

Exposure of Aged Mice to Young Blood Plasma Improves Age-Related Cognitive Impairment? (BBC News / NHS Choices / Nature Medicine / Science)

Summary Researchers at Stanford University believe they might have discovered a novel method of slowing, or even reversing, a range of ageing processes (mental and physical). Their work, based on mice so far, involved injecting the blood of young mice … Continue reading

Protein Involved in Old-Age Memory Loss? (BBC News / Science Translational Medicine)

Summary US researchers working with the donated brains of eight dead people and also performing experiments on mice have discovered indications that low levels of a protein in the brain (called RbAp48) may be responsible for memory loss. This discovery might, one day, lead to treatments … Continue reading
