In the new study, 25 people with social anxiety disorder completed 12 weeks of cognitive-behavioral therapy (CBT), a limited type of psychotherapy that aims to change behavior by changing the way people think about their anxiety and triggers. The researchers used electroencephalograms (EEG) to measure the electrical interactions of the brain before treatment, half of the treatment, and after the last session of CBT. These readings were at rest and during an impromptu speech shot, was asked to give the first two people – a task for a lot of anxiety, social phobia.Srini Pillay, MD, Associate Professor of Psychiatry at Harvard Medical School in Boston and author of Life Unlocked: 7 Revolutionary lessons to overcome fear, is not surprised by new discoveries.
Alan Manevitz, MD, clinical psychiatrist at Lenox Hill Hospital in New York, says the new study is to help build a case based on evidence for the positive effects of psychotherapy.
At 12 weeks of speech therapy, when used to treat the disease, produces changes in brain electrical activity, a new study. The results appear in Psychological Science.
The symptoms of social phobia or social anxiety disorder include and self-consciousness in everyday social situations. This anxiety can also have associated physical symptoms such as speaking sweating, nausea and difficulty. In some cases, anxiety is limited to a specific situation, such as public speaking. In others, it becomes so overwhelming and debilitating that they can not leave the house.
Treatment of social anxiety disorder involves a multifaceted approach to therapies targeting the biology, psychology and behavioral aspects of the disease, he said. Social anxiety can be very debilitating, and we have to deal with it at all these levels.
The results of the EEG were compared with those of two control groups composed of people who have not been diagnosed with social anxiety disorder – a group with high levels of social anxiety and another group of low levels of social anxiety.
The researchers say that there has been a considerable amount of research as used for the treatment of social anxiety disorder affecting the brain, but much less research on how the changes in the brain. The study
Some people in the study were also taking medication for social anxiety, which could skew the results, but researchers have attempted to control for this by ensuring that drug doses remained constant throughout the study. Yet it would be ideal for monitoring patients with drug-free with CBT alone in a future study. However, it is important to note that these plans also present significant challenges, as the majority of outpatients seeking treatment for social anxiety disorder have taken drugs, and asking them to stop these would obviously be contrary to ethics, the study authors say. Speech therapy is a part of the treatment of social phobia
Further studies are needed to determine the effects of the drug. We know that psychotherapy and medicine work better together to psychotherapy alone or medication alone, he said.
Talk therapy produces significant changes in the amount of “delta-beta coupling” seen on the EEG. Delta-beta coupling, a particular pattern of brain waves, increases with increasing anxiety. After 12 weeks of therapy, EEG readings of persons who received CBT were similar to those in the control group who had low levels of social anxiety. In contrast, previous models of delta-beta coupling seen before speech therapy was more similar to those with high levels of anxiety, say the researchers, who were led by Vladimir Miskovic, a PhD candidate at McMaster University in Hamilton, Ontario, Canada.
If these results are generalizable to other anxiety disorders or psychological is not known, but it seems likely based on what is already known about the effects of CBT, the researchers say. Future studies will test specifically for people diagnosed with mood disorders and anxiety for others, they say. Limitations of the study
