Depression Treatment Breakthroughs Scientists are taking on depression from more angles than before. These strategies will help you locate the right drugs and prevent relapses. Psychotherapy is an option if antidepressants do not work. This includes cognitive behavioral therapy as well as psychotherapy with others. Deep Brain Stimulation Deep brain stimulation is a surgical technique that involves the use of electrodes within the brain are placed to target specific areas of the brain that can cause conditions and diseases such as depression. The electrodes are connected to a device which emits electric pulses to treat the disease. The DBS device, also referred to as a neurostimulator, can be used to treat other neurological conditions like epilepsy and Parkinson's disease. The DBS device's pulsing can “jam up” circuits that trigger abnormal brain activity during depression, leaving other circuits unaffected. Clinical trials of DBS have shown significant improvements in patients with treatment resistant depression (TRD). Despite the positive results however, the path to a stable recovery from TRD looks different for every patient. Clinicians must rely on subjective self-reports from interviews with patients and ratings scales for psychiatric disorders, which can be difficult to interpret. Researchers from the Georgia Institute of Technology, Emory University School of Medicine, and the Icahn School of Medicine at Mount Sinai, have developed an algorithm that can detect subtle changes in brain activity patterns and can distinguish between stable and depressive recovery states. The research of the scientists was published in Nature Human Behaviour, exemplifies the importance of combining neuroscience, medicine and computer engineering disciplines to develop potentially life-changing treatments. In DBS procedures, doctors insert a thin wire-like lead into the brain through a tiny hole in the skull. The lead has a series of electrodes at its tips that transmit electrical impulses to the brain. It is then connected to an extension wire that extends from the brain, through the neck and behind the ear, all the way to the chest. The extension wire and the lead are connected to a battery-powered stimulator implanted beneath the skin of the chest. The programmable neurostimulator produces electrical impulses to regulate abnormal brain activity in areas targeted by DBS devices. In the study, researchers utilized DBS to target a specific region of the brain called the subcallosal cingulate cortex (SCC). Scientists found that stimulation of the SCC resulted in an increase in dopamine, which could help alleviate depression symptoms. Brain Scanners A doctor can use a variety methods and tools to diagnose depression, however brain scans are the most effective one. The technology employs imaging to track changes in brain activity on both the structural and functional levels. It can be utilized by a patient to determine the affected regions of their brain and determine the state of these regions in real-time. Brain mapping can also be used to determine which treatment is most efficient for a particular person. For example, some people are more responsive to antidepressant medication than others, but this isn't always the case. By using MRI to assess the effectiveness of a drug, psychologists and physicians can be more precise in prescribing it to their clients. Knowing how their treatment is going can help aid in ensuring better compliance. Despite its widespread prevalence and prevalence, research into mental health has been hindered by the difficulty of assessing it. Although there is a wealth of data regarding depression and anxiety, as well as other conditions, a complete understanding of what causes these disorders has been difficult. Technology is now uncovering the causes of these disorders. For example, a recent study published in Nature Medicine sorts depression into six distinct biological subtypes. This will lead to personalized treatment. Researchers utilized fMRI to study brain activity in 801 people with depression and 137 without. They looked at the activity and connectivity of brain circuits that are affected by depression, such as those that regulate emotions and cognition. They examined a person's brain scan at relaxation and when they completed specific tasks. The results were that a combination of resting state and task-based tests were able to determine if a person would react to SSRIs. This is the first time that a predictive test has been developed in psychiatry. The team is now developing an automated instrument that can make these predictions. This is especially beneficial for those who aren't responding to the typical form of treatment, like therapy and medication. Up to 60% of people with depression do not respond to their initial treatment. Some of those patients are classified as treatment-resistant and can be difficult to treat with a standard regimen However, there is hope that the advancement of technology will allow to improve treatment options. Brain Implants Sarah was suffering from an uncontrollable depression that she described as a black hole that pulled her down to a gravity force so strong she could not move. She tried a variety of medications but none gave her an enduring boost. She also had undergone other treatments, such as ketamine infusions and electroconvulsive therapy however, they failed to work. She decided to undergo surgery to implant electrodes in her brain to send her a targeted shock when she was about have a depressive attack. Deep brain stimulation is a technique that is used extensively in the treatment of Parkinson's disease. It has also been proven to be helpful for some patients who are not able to receive treatment. It is not an effective treatment, but it assists the brain to cope. It is based on a device that places small electrodes into specific areas of the brain. It's like a pacemaker for the mind. In the study published in Nature Medicine on Monday, two researchers at the University of California at San Francisco describe their experience using the DBS to customize the treatment for depression for a specific patient. They called it an “revolutionary” new method that could pave the way for a more flexible DBS treatments for other patients. For Sarah the team traced her brain's circuitry and found that her amygdala is the source of depression episodes. They discovered that a region deep in her brain —– the ventral striatum — was responsible for soothing her amygdala's overreaction. They then implanted the matchbox-sized device in Sarah's brain and attached its electrode legs that resembled spaghetti to the two brain regions. When a symptom of depression is observed, the device signals Sarah's brain to send a small electrical charge to the amygdala as well as to the ventral striatum. This jolt is intended to prevent the onset of depression and to help guide her to a more positive state of mind. It's not a cure for depression, but it makes a big difference for those who need it most. In the future it could be used to identify an indicator of a biological sign that a depression is imminent and allow doctors to prepare by boosting the stimulation. Personalized Medicine The concept of personalized medicine allows doctors to customize diagnosis, prevention and treatment strategies to individual patients, based on the information gathered through molecular profiling. Medical imaging, lifestyle data, etc. This is different from conventional treatments, which are developed to meet the needs of an average patient. Recent research has revealed several factors that cause depression in various patients. These include genetic variation neurocircuitry dysfunctions biomarkers and psychosocial markers among others. Personalized psychiatry aims to integrate these findings in the clinical decision-making for optimal treatment. stay with me is also intended to facilitate the development of individualized treatment approaches for psychiatric disorders such as depression, with the aim of achieving more efficient use of resources and improving patient outcomes. The field of individualized psychiatry continues to grow but there are a few obstacles still hindering its use in clinical settings. For instance, many psychiatrists lack familiarity with the various antidepressants as well as their profile of pharmacology, which can cause a poor prescribing. It is also important to take into consideration the cost and the complexity of the integration of multiomics into healthcare systems as well as ethical concerns. Pharmacogenetics is a promising method to advance the field of personalized psychiatry. It makes use of the genetic makeup of a patient order to determine the correct dosage of medication. It has been suggested that this could aid in reducing drug-related side effects and increase treatment efficacy, especially for SSRIs. However, it is important to emphasize that this is only an option and requires more research before being adopted. Additionally, other factors like environmental influences and lifestyle choices are crucial to consider. The integration of pharmacogenetics into depression treatment should therefore be carefully balanced. Functional neuroimaging is another promising method for guiding the choice of antidepressants and psychotherapy. Studies have shown that the pretreatment levels of certain neural circuits (e.g. ventral and pregenual anterior cingulate cortex) determine the response to psychotherapeutic and pharmacological treatments. Moreover, some clinical trials have already used these findings to help select participants, focusing on those who have greater levels of activation and thus having more favorable responses to treatment.
