The Mood Disorders Research Program at St. Luke's Roosevelt Hospital Center in New York performs studies of various psychiatric conditions.

Studies of chronic depression.  In the past decade, it has become clear that many people with depression have symptoms that last for many years.  Dysthymic Disorder (DD) is one form of  chronic depression.  Less severe than Major Depression, DD tends to start in adolescence or earlier, and to last for years, even decades.  Symptoms include low mood (lasting 2 or more years), sadness, listlessness, an inability to enjoy things, low self-esteem, and poor concentration.  Though DD is fairly mild on a day-to-day basis, over a lifetime it is actually a severe disorder—leading to poor work function, relationship problems, and high rates of suicide. 

In recent years, a variety of medication treatments have been shown to be helpful for Dysthymic Disorder.  At the Mood Disorders Research Program, we have studied medications such as Prozac, Zoloft, Wellbutrin, Effexor, and Celexa.  Our studies have shown that for most people, the longstanding symptoms of depression can be relieved in as little as four to eight weeks.  Interestingly, not only do sleep and appetite improve, but many people also are able to work more productively and have better relationships.
