It’s as good as new. An asthma drug has rejuvenated rat brains, making old rats perform as well as young rats in tests of memory and cognition. The drug also encouraged the birth of new brain cells.
As we get older, most of us will experience some kind of brain degeneration. Typically, we lose the ability to make new neurons. Another problem is chronic, low-grade inflammation in the brain, which is implicated in many age-related brain disorders.
A drug called montelukast (Singulair), regularly prescribed for asthma and allergic rhinitis, blocks these receptors, so Aigner and his colleagues tried it on young and old rats. The team used oral doses equivalent to those taken by people with asthma.
