Scientists have discovered the effectiveness of Deep Brain Stimulation in curing Alzheimer's, memory disorders and anorexia.
Recently researchers from the Bonn University of Germany have discovered some amazing effects of Deep Brain Stimulation in acute depression. Prof Volker Arnd Coenen and Prof. Thomas E. Schläpfer published their study in the Journal Biological Psychiatry.
The scientists said that both these regions of the brain are concerned with the feelings of euphoria and ecstasy.
The experts said that the therapy is effective when a relatively weak electric current was used.
The scientists from Bonn University have noticed that six out of seven seriously-depressed test subjects revealed a marked lowering in depression symptoms such as anxiety, listlessness, despondence and joylessness within few days of the onset of treatment. After the treatment, experts monitored the volunteers for 18 months.
In past studies, a high current was used for the treatment and the results appeared in few weeks and the treatment was beneficial for only 50 percent of patients. The scientists at UCLA believed that the success rate of the treatment using Stimulation of external Trigeminal Nerve on the foreheads of the depressed volunteers was more effective.
Dr. Rothschild said, "Treatment-resistant depression is a horrible disease. It can result in death, and people who live with it often have very difficult lives." He added, "These impressive findings in the medial forebrain bundle must now be replicated in a double-blind fashion, like the study we're doing with Brodmann Area 25 - that's the way to prove it."
Dr. Rothschild, the Irving S. and Betty Brudnick Endowed Chair and professor of psychiatry mentioned, "Every patient knew they were receiving the treatment, which increases the likelihood of a placebo effect. Studies like these are important first steps but, until you do the double-blind study in which some patients have the device turned on, and some do not, and the patients don't know which group they are in, you can come to inaccurate conclusions."
The scientists concluded that further studies are needed to ascertain the effectiveness of Deep Brain Stimulation (DBS) in treating depression.
