Depression Treatment Breakthroughs Scientists are taking on depression from different ways than they did before. These strategies aim to help you find the right drugs and prevent repeat relapses. Psychotherapy is an option if antidepressants aren't working. This includes cognitive behavior therapy as well as psychotherapy with others. Deep Brain Stimulation Deep brain stimulation is a surgical technique where electrodes inside the brain are used to target specific areas of the brain that cause conditions and diseases like depression. The electrodes are connected to a device which emits electric pulses in order to treat the disease. The DBS device is called neurostimulator. It is also used to treat other neurological disorders such as Parkinson's disease, essential tremor and epilepsy. The DBS device's pulsing may “jam up” circuits that trigger abnormal brain activity during depression, leaving other circuits unaffected. Clinical trials of DBS for depression have demonstrated significant improvement in patients suffering from treatment-resistant depression (TRD). Despite the positive results, the path to stable recovery from TRD differs for each patient. Clinicians rely on the subjective reports from interviews with patients and psychiatric ratings scales that are difficult for them to interpret. Researchers from the Georgia Institute of Technology and Emory University School of Medicine have developed an algorithm that can detect subtle changes in brain activity patterns. This algorithm can differentiate between depressive and stable recovery states. The researchers' research, published by Nature Human Behaviour in Nature, highlights the importance of combining medical and neuroscience disciplines with computer engineering to develop potentially life-changing treatments. During DBS the doctors insert a thin, wire-like lead into the brain through a small hole in the skull. The lead is equipped with a variety of electrodes on its tip that transmit electrical signals to the brain. The lead is connected to an extension cable that extends from the head, through the ear and down to the chest. The extension and the lead are connected to a stimulator powered by batteries implanted under the skin of the chest. The programmable neurostimulator produces pulses of electricity to control abnormal brain activity in areas that are targeted by DBS devices. In the study, the team employed DBS to target a specific region of the brain called the subcallosal cingulate cortex (SCC). Scientists discovered that stimulation of the SCC resulted in a rise in dopamine, which can aid in the treatment of depression. Brain Scanners A doctor may use various methods and tools to diagnose depression, but the best one currently available is a brain scan. This technique employs imaging to track changes at the functional and structural levels of brain activity. It can be used to determine the regions of a patient's brain that are affected by the disorder and determine what is happening in those regions in real time. Brain mapping can help to predict the kind of treatment that is most effective for a particular person. For example, some people are more responsive to antidepressant medications than others, but this isn't always the case. Psychologists and doctors can prescribe medications more precisely when they utilize MRI to assess the effectiveness. Monitoring how their treatment improving can aid in ensuring better compliance. Despite its widespread prevalence and prevalence, research into mental health has been hindered by the difficulty of assessing it. While there is a plethora of data regarding depression anxiety, depression and other issues, a comprehensive understanding of what causes these conditions has been difficult to come by. New technology is now uncovering the underlying causes of these disorders. For instance, a recent study published in Nature Medicine sorts depression into six distinct biological subtypes. This opens the way to a personalized treatment. Researchers used fMRI technology to examine the brain activity of 801 individuals who suffer from depression, and 137 people who are not. They examined the activity and connectivity of brain circuits affected by depression, such as those that control cognition and emotions. They examined a person's brain scan at rest and while completing specific tasks. The results showed that a combination of resting state and task-based measures could be used to determine whether or not a person would respond to SSRIs. This is the first time a predictive test has been created in psychiatry. The team is currently working on an automated tool that will give these results. This is particularly helpful for those who don't respond to standard treatments such as therapy and medication. About 60% of those suffering from depression are not responding to their initial treatment. Some of these patients could be difficult to manage with the standard treatment regimen. Brain Implants Sarah was suffering from a severe form of depression that was debilitating. She described it as a dark hole that pulled her down. It was a force so powerful that she was unable to move. She had tried all sorts of medicines however none of them had given an indefinite lift. She had also undergone other treatments, such as electroconvulsive therapy and ketamine infusions, but they too failed to work. She decided to undergo surgery to implant electrodes in her brain, which would give her a targeted shock when she was nearing having an attack of depression. The procedure, known as deep brain stimulation is used extensively to treat Parkinson's disease and has been proven to help those suffering from depression that is resistant to treatment. However, it's not a cure, but rather aids the brain in dealing with the condition. It's based on a device that places small electrodes in specific parts of the brain. It's like a brain pacemaker. In a study published in Nature Medicine on Monday, two researchers from the University of California at San Francisco describe their experience using a DBS to create a custom treatment for depression in a specific patient. They described it as an “revolutionary” new method that could open the door for customizable DBS treatments for other patients. For Sarah The team mapped the circuits in her brain and discovered that her amygdala was a cause of depression-related episodes. They found that a spot deep in her brain -the ventral striatum- was responsible for soothing her amygdala's excessive reaction. Then, they implanted a matchbox-sized device into Sarah's skull, and then strung its spaghetti-like electrode legs down to the two brain regions. If depression treatment modalities of depression is observed, the device signals Sarah's brain to send a tiny electrical charge to the amygdala and to the ventral striatum. The intention is to stop depression and motivate her to be more positive. It's not a cure, however, it can make a big difference for those who need it the most. In the future, it could be used to determine an indicator of a biological sign that a depression is imminent, allowing doctors to prepare by boosting the stimulation. Personalized Medicine The concept of personalized medicine refers to adapting diagnosis, prevention and treatment strategies for individual patients based on information gathered through molecular profiling, medical imaging, lifestyle data and more. This differs from conventional treatments, which are developed to be adapted to the needs of a typical patient. Recent research has revealed several factors that cause depression in various patients. These include genetic variations and neural circuitry dysfunctions as well as biomarkers, psychosocial markers and others. The purpose of psychiatry that is customized is to integrate these findings into the clinical decision-making process to ensure the best treatment. It also intends to facilitate the development and implementation of specific treatment plans for psychiatric issues such as depression. Personalized psychiatry continues to progress, but several obstacles are still preventing its clinical application. Many psychiatrists aren't familiar with the pharmacological profile of antidepressants. This can result in a suboptimal prescription. Additionally, the complexity and cost of the integration of multiomics data into healthcare systems as well as ethical considerations have to be considered. Pharmacogenetics could be a promising approach to advance the field of personalized psychotherapy. It uses the patient's genetic makeup in order to determine the correct dose of medication. This could reduce side effects of medications and improve treatment effectiveness, especially with SSRIs. However, it is crucial to emphasize that this is just an option and requires further research before being widely implemented. Additionally, other factors like lifestyle choices and environmental influences are essential to consider. The integration of pharmacogenetics into treatment for depression must be carefully balanced. Functional neuroimaging can also be utilized to aid in the selection of antidepressants or psychotherapy. Studies have proven that pretreatment activation levels of specific neural circuits (e.g. The response to psychotherapeutic or pharmacological treatment is predicted by the ventral and pregenual anterior cortex. Moreover, some clinical trials have already utilized these findings to help select participants, targeting those with greater levels of activation and thus having more favorable responses to treatment.
