Cognitive enhancement drugs do not help improve cognition or function in the long term for patients with mild cognitive impairment, a new study shows.
Researchers erase drug associated memories in mice and rats without affecting other memories.
Researchers find degeneration of the fornix can identify those at risk of cognitive decline long before clinical symptoms appear.
Researchers describe in detail the underlying neurobiology of the "world's second most famous amnesiac", EP, who suffered profound memory loss after damage to key portions of his brain.
Using the nerve cells of sea snails, researchers reverse memory loss by determining when cells were primed for learning. Retraining cells with the use of an optimized training schedule helped compensate for memory loss.
Fear responses can only be erased when people learn something new while retrieving the fear memory according to a new study.
A new study suggests that blood may hold clues to whether post-menopausal women may have an increased risk for brain damage that can lead to memory problems and an increased risk of stroke.
Scientists have discovered that significantly more neurons are generated in the brains of older animals if the signaling molecule Dickkopf-1 is turned off. The results give rise to the question whether the function of Dickkopf-1 may be turned off using drugs to prevent age related cognitive decline.
When the brain produces too much nitric oxide, it contributes to the severity and progression of stroke and neurodegenerative diseases such as Alzheimer’s. Researchers recently discovered that nitric oxide not only damages neurons, it also shuts down the brain’s repair mechanisms.
