Anxiety Disorder Research
Anxiety disorder is a mental sickness on which many of research and studies are still being performed to fully comprehend how it works and how to treat it. We have grown by leaps and bounds since anxiety disorder was first noticed and recorded hundreds of years ago and yet, we are still perhaps at the tip of the iceberg in terms of fully understanding what goes on in the brains of people who suffer from this illness. Here are some of the the bulk recent studies and researches being done for the treatment of anxiety disorder: What are the recent studies or findings regarding medications used for anxiety disorder? Generally, anxiety disorder is treated with medication, psychotherapy (behavioral or cognitive) or a combination of both. Some researchers are performing a clinical trial that tries to examine how effective these treatments are when used either separately or together against obsessive-compulsive behavior, one of the average forms of anxiety disorder. Researchers also hope to determine how to alleviate the relapse rate that rises when drug therapy is stopped. On medications, a new drug called buspirone has featured promise as an anti-anxiety medication. However, research is still ongoing on whether it will perform better if used with anti-depressant drugs that have an effect on serotonin. How do hormones influence anxiety disorders? To a certain degree, some hormones seem to influence certain forms of anxiety disorder, such as post-traumatic stress disorder or PTSD. People diagnosed with the sickness have featured to have low levels of cortisol, a stress hormone. On the other hand, they have extremely high levels of norepinephrine, epinephrine. Researchers believe the levels of these hormones in the body causes a person to feel anxiety even after some period of time has passed since the occurrence of the stressful event. High levels of CRF or corticotropin releasing factor might also be the reason why it's so easy to startle people with PTSD. Researchers hope to find methods to regulate the imbalances in the hormones and manage symptoms. What about brain imaging technology? Brain imaging technology together with techniques using neurochemical tests, have been used to treat anxiety disorder. NIMH (National Institute of Mental Health) has used the same technology to be able to see a living brain and note modifications in its parts such as the cortex and the amygdala. Through controlled observation, scientists would be able to determine whether activity in the brain is abnormal and how certain areas are affected by therapies or medication. Brain imaging technology has figured significantly recently. Recent studies conducted on the brains of people with obsessive-compulsive behavior using magnetic resonance showed that their brains contained considerably less white matter than common subjects. This indicates that the abnormality in the brains of OCD patients is more widely distributed than it was earlier believed. Is it possible to predict or prevent the occurrence of mental illness? Part of research conducted in the field of psychiatry involves prevention efforts. This focuses on trying to comprehend how mental traumas such as anxiety illnesses develop and how they can be impeded at certain points. By knowing how mental traumas begin, researchers hope to be able to perform interventions at significant points during the course of the disorder. They also hope to use the newest advances in research performed in the fields of biomedicine, cognitive and behavioral sciences to help in their efforts for prevention. Is there a possible genetic pre-disposition for anxiety disorder? A 2001 study made by the American Journal of Psychiatry seems to express that anxiety disorder in the form of depression and panic disorder sprint in families. Children whose parents have been diagnosed or are suffering from anxiety disorder are more likely to develop the disorder themselves. The study also displays that children may be laid bare to specific illnesses that produce clear cut risks. For example, parents who suffer from a panic disorder may increase the risk of their children developing not only panic disorder but also agoraphobia. Parents who suffer from depression increase the risk of their children developing social anxiety disorder, disruptive behavior and depression. While the study displays that children in households where parents have some form of anxiety disorder are at risk, it doesn’t prove whether they are genetically pre-disposed to the sickness itself. However, the study of whether anxiety disorder and other mental traumas are affected by genetics does not end there. A project called the Human Genetics Initiative hopes to be able to find the genes responsible for mental traumas by compiling a registry of all families with a history of bipolar disorder, schizophrenia and other mental illnesses. By finding a average gene, they may be able to find out whether mental sickness can be passed on genetically or not. How does this study influence treatment? This study reiterates the importance of early diagnosis and treatment of anxiety disorder. People in the initial stages of an anxiety disorder must be treated before the sickness becomes chronic. By then, there is a likelihood that it would be too advanced to react to treatments. Through this study, researchers and psychiatrists hope to be able to develop newer ways and processes to prevent anxiety illnesses in children before they even begin. |
