A new study indicates that medication can reverse many of the defining symptoms of fragile X syndrome in mice, a finding which could have implications for people with other developmental disabilities too.
The development reported Thursday in the journal Neuron is significant, scientists say, because the treatment brought about major changes even in adult mice with fragile X, the most common form of inherited intellectual disability.
For the study, researchers looked at a new drug intended to target a protein in the brain that’s been linked to fragile X. Mice given the medication began exhibiting fewer symptoms of the condition, researchers said. Improvements were seen in learning and memory capabilities as well as behavioral areas, with the mice becoming less sensitive to sound, for example.
