Suicide is a very real risk for young people who suffer from clinical depression. In fact during the past two years suicide has increased among youths between the ages of 10 and 19, but there aren’t treatments that can help. Researches show that the most effective treatment is the combination of anti-depression and talk therapy. Anti-depressants work by increasing chemical which facilitate communications between neurons in the brain. "Anti-depressants are the most effective treatment for most adults. But when it comes to teenagers, it’s not enough." Says Doctor Richard, a psychiatrist in university medical center. 13 age years are full of turmoil, emotions and changes. And there are family conflicts and conflicts with relationship that can contribute to distress in adolescents", Richard says. And anti-depressant medications may not be able to deal with all of those problems. "Psycho therapy, specifically problem-behavioral therapy need to be combined," he says. In his recent major study, with the therapy in use along with anti-depressants., 75% of kids are reported feeling better and less suicidal after 3 month probably because the problem-behavioral therapy tackle thinking and feeling in a very particular way that medicines may not. And in particular suicidal case, "It intervenes in a positive way " Say doctor Finland, a psychiatrist with Richard in the medical college.
