http://www.medicalnewstoday.com/healthnews.php?newsid=43776A trial carried out by Dr. Eric Finzi and Dr. Erika Wasserman found that treating clinically depressed patients with botox on the frown lines of their faces actually got rid of their depression.
...
They selected ten patients who had ongoing major depression despite drug and psychotherapeutic treatment. They were evaluated with the Beck Depression Inventory II (BDI-II) before receiving botox treatment on their frown lines.
...
Nine patients were no longer depressed two months after botox treatment on their frown lines. One patient experienced no improvement in mood.
Hmmm. Sounds like what I've heard some other places: "when you feel down, smile. Your mood will change for the better." Seriously, those suffering from long-term depression should seek counseling.
