Does protein hold cure to postnatal depression?
Postnatal depression may be caused by a lack of a certain kind of protein, scientists in the States have discovered.
In what is being heralded as an important breakthrough into this unhappy affliction, experiments on mice have shown that animals lacking a specific protein failed to make nests or connect with their babies.
However, when they were given a drug containing the protein, they switched back to a more normal mood and more of their offspring survived.
Now boffins at the University of California plan to do more research into the chemical, known as gamma aminobutyric acid (GABA), which they believe could be the key to helping woman cope with the hormone changes during and after pregnancy.
