The research revealed that mice fed an LMN diet, when compared to those fed a control diet, have more cell proliferation in the two areas of the brain where neurogenesis is produced, the olfactory bulb and the hippocampus.

After that, patients would be forced to compensate for the lost function by focusing on their remaining abilities. Although this belief has been refuted, an occupational therapy professor believes that the current health system is still not giving patients enough time to recover.

In order to answer that key question and develop new approaches to preventing the damage, scientists must first understand how amyloid-beta forms the telltale clumps. Researchers have now developed new molecular tools that can be used to investigate the process.

Scientists analyzing this inflammatory response in mice discovered that the types of cells recruited to the site of the injury are dominated within a week by those that promote inflammation. When chronic, inflammation can prevent healing, and these inflammatory cells are believed to remain at the injury site indefinitely.
