Depression Treatment Breakthroughs
Scientists are attacking depression in elderly treatment from more angles than ever before. These strategies aim to help you find the right medication and prevent the possibility of relapse.
Psychotherapy is an option when antidepressants do not work. These include cognitive behavioral therapy and psychotherapy with others.
Deep Brain Stimulation
Deep brain stimulation is a surgical procedure that involves the use of electrodes within the brain are placed to target specific areas of the brain that are responsible for disorders and conditions such as depression. The electrodes connect to an instrument that emits pulsing electric pulses to help treat the condition. The DBS device is called a neurostimulator. It can also be used to treat other neurological disorders such as essential tremor, Parkinson's disease epilepsy, and essential tremor. The pulsing of the DBS device could "jam" circuits that are causing abnormal brain activity in depression, while keeping other circuits in place.
Clinical studies of DBS have demonstrated significant improvements in patients with treatment resistant depression treatment without medication (TRD). Despite positive results, TRD recovery looks different for every patient. Clinicians rely on subjective information 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 a method to detect subtle changes in the brain's activity patterns. This algorithm can differentiate between depressive and stable recovery states. The study published in Nature Human Behaviour in Nature, highlights the importance of combining medical and neuroscience disciplines and computer engineering to create potentially life-changing treatments.
In DBS, doctors insert a thin wire-like lead into the brain through a small hole in the skull. The lead is equipped with electrodes that send electrical signals to the brain. The lead is connected to an extension cable that extends from the head, behind the ear and down 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 current pulses to control abnormal brain activity within the areas that are targeted by DBS devices. The team used DBS in the study to target a brain region called the subcallosal cortex (SCC). Researchers found that stimulation of the SCC resulted in an increase in dopamine, which can help alleviate depression symptoms.
Brain Scanners
A doctor may use a variety of tools and techniques to diagnose depression, but the most effective one currently available is a brain scan. This technique uses imaging in order to track changes at the structural and function levels of brain activity. It can be used by a patient to pinpoint the affected areas of their brain, and then determine the state of these regions in real-time.
Brain mapping can help determine the type of treatment will be most effective for a particular person. Some people respond better to antidepressant medications than others. However this isn't always the case. Psychologists and physicians can prescribe medications more accurately if they use MRI to measure the effectiveness. It can also help increase compliance by allowing patients to view how their treatment is progressing.
The difficulty of assessing mental health has hindered research despite the widespread prevalence. There is an abundance of information about depression anxiety, depression, and other disorders. However it's been difficult to pinpoint the causes. The latest technology is revealing the mechanisms behind these disorders.
For instance, a recent study published in Nature Medicine sorts depression into six distinct biological subtypes. This paves the way toward personalized treatment.
Researchers used fMRI technology to study the brain activity of 801 individuals with depression during pregnancy treatment, and 137 others without. They looked at the activation and connectivity of brain circuits affected by depression, such as those that regulate emotions and cognition. They examined a participant's brain scan during relaxation and when they completed specific tasks.
A combination of resting-state and task-based tests could predict whether an individual would respond to SSRIs. This is the very first time a predictive test in the field of psychiatry was developed. The team is currently developing an automated instrument that can make these predictions.
This is especially useful for those who don't respond to conventional treatments like therapy and medication. In fact, as high as 60 percent of those suffering from depression don't respond to the first treatment they receive. Certain patients may be difficult to manage using an established treatment plan.
Brain Implants
Sarah had lived with an uncontrollable depression that she described as a black hole that dragged her down, a force of gravity that was so strong that she was unable to move. She had tried all sorts of medicines, but none had provided a lasting lift. She also tried other treatments such as ketamine injections and electroconvulsive treatments, but they did not work either. Then, she decided to undergo a surgery which would allow researchers to implant electrodes in her brain and give her a targeted jolt whenever she was about to experience a depressive episode.
The method, also called deep brain stimulation is widely used to treat Parkinson's disease and has been shown to help some people with treatment-resistant depression. It's not a cure, but it assists the brain to cope. It utilizes a device that can implant small electrodes in specific brain regions, like a pacemaker.
In the study published in Nature Medicine on Monday, two researchers from the University of California at San Francisco describe their experience using a DBS to customize depression treatment for a particular patient. They described it as an "revolutionary" new approach that could open the way for the development of 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 the ventral striatum, a deep part of her brain was responsible for calming her amygdala's overreaction. They then implanted the matchbox-sized device in Sarah's brain and attached its electrode legs that resembled spaghetti to these two regions.
If a sign of depression occurs, the device signals Sarah's brain to send a tiny electrical charge to the amygdala as well as to the ventral striatum. The intention is to stop depression and motivate her to be more positive. It's not an effective treatment for depression, however it makes a significant difference for the people who require it the most. In the future, it could be used to determine a biological marker that a depression is coming, allowing doctors to prepare by increasing the stimulation.
Personalized Medicine
The concept of personalized medicine refers to adapting diagnosis, prevention and treatment strategies to specific patients based on information obtained through molecular profiling, medical imaging, lifestyle information, etc. This differs from traditional treatments, which are designed to meet the needs of an average patient.
Recent studies have revealed a variety factors that contribute to depression treatment during pregnancy among different patients. These include genetic variations and neural circuitry malfunctions biomarkers and psychosocial markers among others. The purpose of psychiatry that is customized is to incorporate these findings into the decision-making process for clinical care for optimal care. It also intends to assist in the creation and implementation of individualized treatment for psychiatric conditions such as depression.
Personalized psychiatry continues to progress however, there are many obstacles still preventing its clinical application. For example, many psychiatrists lack familiarity with the various antidepressants as well as their chemical profiles, which could result in a suboptimal prescription. Additionally, the complexity and cost of integrating multiomics data into healthcare systems, as well as ethical considerations need to be taken into account.
One promising avenue to advance the personalized psychiatry approach is pharmacogenetics. It aims at utilizing the patient's unique genetic makeup to determine the appropriate dose of medication. It has been suggested that this can aid in reducing drug-related side effects and increase treatment efficacy, especially in the case of SSRIs.
However, it is crucial to note that this is merely an option and requires more research before being implemented. Additionally, other factors such as lifestyle choices and environmental influences are crucial to consider. The integration of pharmacogenetics and lifestyle choices in depression treatment should therefore be carefully balanced.
Functional neuroimaging can also be utilized to aid in the choice of antidepressants or psychotherapy. Studies have demonstrated that the activation levels in specific neural circuits (e.g. The response to pharmacological or psychotherapeutic treatment is determined by the ventral and pregenual anterior cortex. Certain clinical trials have utilized these findings as a basis to select participants. They are targeted at those who have higher activation and, therefore more favorable reactions to treatment.
