Shattered expectations, distance from dear ones, incapability to match pace with the fast running life are some conditions that can throw a person into the abyss of depression. Depression is the result of this fast moving world. Studies have shown that some people are born with the Major Depressant Disorder. According to statistics, approximately 120 million people suffer from severe depression. Studies have shown that 20% depression cases are unresponsive to treatment of depression like psychotherapy, medication and shock therapy. Nearly 15% such cases end their lives.

A recent study done by the doctors of Toronto Western Hospital has shown that the severe depression cases could be treated with deep brain stimulation (DBS).Under DBS, electrodes are implanted into the brain, through which electrical impulses known as subcallosal cingulate gyrus (SCG) are delivered.

Under this study, 20 patients with major depressant disorder (a form of severe depression) were treated with this technique.60% patients showed improvement in their condition. The study showed that the patients treated with DBS showed improvement in their eating habits, moods, anxiety levels and sleeping patterns.
 
Lead author of the study, Dr. Andres Lozano, a neurosurgeon at Toronto Western Hospital said, “The procedure is well tolerated and no patient suffered a permanent serious adverse effect." He added that as compared to the previously utilized ablative neurosurgical procedures for depression, DBS is adjustable and stimulation is reversible. He claimed that these features increase the safety and offer advantages for both the efficacy of the therapy and its acceptance in the patient, medical, and psychiatric community.

The researchers said that the patients didn’t suffer from any kind of permanent side effects after DBS treatment. They claimed that this method is absolutely safe for the people. This method can save many lives. This method has brought a hope of life for those people who suffer from severe depression.
