Taste test?

Scientists have noted that otherwise healthy persons taking selective serotonin reuptake inhibitors--antidepressants such as Prozac and Lexapro--become extra sensitive at detecting sweet and bitter tastes. On the other hand, volunteers taking selective norepinephrine reuptake inhibitors like Effexor improved their detection of sour and bitter tastes.

These neurotransmitters, serotonin and norepinephrine, are known to be involved in taste signaling as well as mood control. Physiologist Lucy Donaldson of the University of Bristol felt this connection might be useful in the treatment of depression. She concluded:

It may be feasible to use a simple taste test to see what kind of medication people should be given.
