Enhanced Environment Restores Memory in Mice with Neurodegeneration

Mice whose brains had lost a large number of neurons due to
neurodegeneration regained long-term memories and the
ability to learn after their surroundings were enriched with
toys and other sensory stimuli, according to new studies by
Howard Hughes Medical Institute researchers. The scientists
were able to achieve the same results when they treated the
mice with a specific type of drug that encourages neuronal
growth. The new studies suggest two promising avenues for
treatment that might alleviate learning deficits and memory
loss in humans with Alzheimer's disease or other
neurodegenerative diseases.

Research published in the April 29, 2007, issue of Nature.
