Depression Treatment Breakthroughs
Researchers are tackling depression from a variety of angles than before. These strategies will help you locate the right drugs and avoid the possibility of relapse.
Psychotherapy is an option when antidepressants don't work. These include cognitive behavior therapy and psychotherapy with others.
Deep Brain Stimulation
Deep brain stimulation (DBS) is an operation where electrodes are implanted inside the brain to target specific brain regions that are responsible for diseases and conditions like depression. The electrodes connect to the device that emits electric pulses to help treat the disease. The DBS device is called a neurostimulator. It can also be used to treat other neurological disorders such as essential tremor, Parkinson's disease, and epilepsy. The pulses of the DBS device can "jam" circuits that cause abnormal brain activity in depression while keeping other circuits in place.
Clinical studies of DBS have shown significant improvements for patients suffering from treatment resistant depression (TRD). Despite these positive results TRD recovery is not the same for every patient. Clinicians must rely on their own subjective reports from patient interviews as well as the psychiatric rating scales that 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 differentiate them from depressive versus stable recovery states. The scientists' research is published in Nature Human Behaviour, exemplifies the importance of combining neuroscience, medical and computer engineering disciplines to develop potentially life-changing therapies.
In DBS procedures, doctors insert a thin, wire-like lead into the brain through a small hole in the skull. The lead is outfitted with electrodes which send electrical signals to the brain. It is then connected to an extension wire that runs from the brain, across the neck and behind the ear, all the way to the chest. The extension wire and the lead are connected to a stimulator powered by batteries implanted beneath the skin of the chest.
The programmable neurostimulator generates electric pulses to regulate abnormal brain activity in areas targeted by DBS devices. In the study, the researchers employed DBS to target a specific region of the brain referred to as the subcallosal cingulate cortex (SCC). Scientists discovered that stimulation of the SCC caused a rise in dopamine, which can help alleviate depression symptoms.
Brain Scanners
A doctor may employ a variety methods and tools to diagnose depression, however the brain scan is the most effective one. This method employs imaging to track changes at the functional and structural levels of brain activity. It can be used by a client to determine the affected regions of their brain and determine the state of these regions in real-time.
Brain mapping can help predict the kind of treatment that is most effective for an person. Some people respond better antidepressant medication than others. However it's not always the case. With the use of MRI to evaluate the effectiveness of a drug psychologists and doctors are more precise in prescribing it to their patients. It can also help to improve compliance by allowing patients to view how their treatment is progressing.
Despite its wide-spread prevalence and prevalence, research into mental health has been hindered by the difficulty in measuring it. There is plenty of information available on depression, anxiety, and other disorders. However it's been difficult to understand what causes them. However, the latest technology is beginning to reveal the mechanisms behind these conditions.
For example, a recent study published in Nature Medicine sorts depression into six distinct biological subtypes. This will lead to individualized treatment.
Researchers employed fMRI technology in order to analyze the brain activity of 801 individuals with depression, and 137 others who were not depressed. Researchers studied the activity of brain circuits that are affected by depression, such as those that regulate emotions or cognition. They examined the brain scans of a person at rest and when completing specific tasks.
The results showed that a combination of resting-state and task-based measures could be used to predict whether or not someone would respond to SSRIs. This is the very first time a predictive test for psychiatry has been developed. The team is currently working on an automated tool that will give these predictive results.
This is especially beneficial for people who are not responding to the typical method of treatment, like therapy and medication. Up to 60% of those suffering from depression don't respond to their first treatment. Some of these patients are referred to as treatment-resistant and can be difficult to treat with standard treatment however, the hope is that new technologies will help to optimize treatment options.
Brain Implants
Sarah was suffering from a severe form of depression. She described it as a black hole that dragged her down. It was a force so powerful that she was unable to move. She tried a variety of drugs but none gave her a lasting boost. She also tried other treatments like ketamine injections or electroconvulsive therapy, but they failed too. Then, she decided to undergo a surgery that would permit researchers to implant electrodes in her brain to send her a specific jolt whenever she was about to experience a depressive episode.
Deep brain stimulation is a method which is extensively used in the treatment of Parkinson's disease. It has also been shown to be helpful for some people who are resistant to treatment. But it's not a cure; it simply assists the brain in coping with the disease. It makes use of a device to implant tiny electrodes into specific areas of the brain like the pacemaker.
In the study published in Nature Medicine on Monday, two researchers from the University of California at San Francisco explain how they utilized a DBS to tailor treatment for depression in a specific patient. They described it as a "revolutionary" method that could allow custom DBS treatments to be offered to other patients.
For Sarah The team mapped the circuits in her brain and discovered that her amygdala is the cause of depression-related episodes. They found that a specific area deep in her brain -- the ventral striatum -which was responsible for calming her amygdala's overreaction. Then, they implanted a matchbox-sized device into Sarah's skull, and then strung its spaghetti-like electrode legs down to those two regions.
When a depression symptom occurs, the device sends an electrical signal to Sarah's amygdala, as well as ventral striatum. This shock is intended to reduce depression and help her to be more positive. It's not an effective treatment for depression, however, it can make a huge difference for the people who require it the most. In the future, it could be used to determine the biological signs that indicates a depression is on the way and allows doctors to prepare by turning up the stimulation.
Personalized Medicine
Personalized medicine is a method to customizing diagnosis, prevention and treatment strategies to specific patients based upon information gathered through molecular profiling, medical imaging, lifestyle data, etc. This differs from traditional treatments, which are designed to be adapted to the needs of a typical patient.
Recent studies have revealed a variety factors that cause depression in a variety of patients. These include genetic variation and neural circuitry malfunctions biomarkers, psychosocial markers and biomarkers among others. The goal of psychiatry that is personalized is to integrate these findings into the decision-making process for clinical care for optimal treatment. It also aims to assist in the creation and implementation of specific treatment plans for psychiatric issues such as depression.
The field of individualized psychiatry continues to grow, but several obstacles are still preventing its clinical application. Many psychiatrists aren't familiar with the pharmacological profiles of antidepressants, which could result in a suboptimal prescription. It is also essential to think about the cost and complexity of integrating multiomics into healthcare systems, as well as ethical considerations.
Pharmacogenetics is a promising way to advance the field of personalized psychotherapy. It utilizes the genetic makeup of a patient order to determine the appropriate dosage of medication. It has been suggested that this can help to reduce adverse effects of drugs and boost the effectiveness of treatment, particularly when it comes to SSRIs.
However, preventive measures for depression is important to note that this is just an option and requires more research before it is widely accepted. Other factors, such as lifestyle choices and environmental influences are also important to consider. Therefore the integration of pharmacogenetics into depression treatment must be and balanced.
Functional neuroimaging is yet another promising method to guide the choice of antidepressants as well as psychotherapy. Studies have shown that the pretreatment levels of certain neural circuitries (e.g. ventral and pregenual anterior cingulate cortex) determine the response to both pharmacological and psychotherapeutic treatments. Additionally, certain clinical trials have already utilized these findings to guide their selection of participants, targeting those with higher activation levels and therefore showing more favorable responses to treatment.
