Personalized Depression Treatment Traditional therapy and medication are not effective for a lot of patients suffering from depression. The individual approach to treatment could be the solution. Cue is an intervention platform that transforms sensor data collected from smartphones into personalised micro-interventions that improve mental health. We analyzed the best-fitting personalized ML models to each person, using Shapley values to determine their characteristic predictors. The results revealed distinct characteristics that were deterministically changing mood over time. Predictors of Mood Depression is among the leading causes of mental illness.1 However, only about half of those suffering from the condition receive treatment1. To improve the outcomes, doctors must be able identify and treat patients who are the most likely to benefit from certain treatments. A customized depression treatment plan can aid. Researchers at the University of Illinois Chicago are developing new methods for predicting which patients will benefit most from certain treatments. They use mobile phone sensors, a voice assistant with artificial intelligence as well as other digital tools. With two grants awarded totaling more than $10 million, they will make use of these techniques to determine biological and behavioral predictors of the response to antidepressant medication and psychotherapy. So far, the majority of research on factors that predict depression treatment effectiveness has centered on sociodemographic and clinical characteristics. These include demographic factors such as age, gender and education, clinical characteristics including the severity of symptoms and comorbidities and biological indicators such as neuroimaging and genetic variation. Few studies have used longitudinal data to determine mood among individuals. Many studies do not take into consideration the fact that mood varies significantly between individuals. It is therefore important to develop methods that permit the identification and quantification of individual differences between mood predictors treatments, mood predictors, etc. The team's new approach uses daily, in-person evaluations of mood and lifestyle variables using a smartphone app called AWARE, a cognitive evaluation with the BiAffect app and electroencephalography — an imaging technique that monitors brain activity. This allows the team to develop algorithms that can identify different patterns of behavior and emotions that vary between individuals. The team also devised an algorithm for machine learning to identify dynamic predictors of each person's depression mood. The algorithm blends the individual differences to produce a unique “digital genotype” for each participant. This digital phenotype has been linked to CAT DI scores which is a psychometrically validated symptom severity scale. The correlation was low, however (Pearson r = 0,08, P-value adjusted by BH 3.55 x 10 03) and varied greatly among individuals. Predictors of symptoms Depression is among the world's leading causes of disability1 but is often not properly diagnosed and treated. In addition the absence of effective treatments and stigma associated with depressive disorders prevent many from seeking treatment. To assist in individualized treatment, it is crucial to determine the predictors of symptoms. Current prediction methods rely heavily on clinical interviews, which aren't reliable and only identify a handful of symptoms associated with depression. Machine learning is used to blend continuous digital behavioral phenotypes captured by smartphone sensors and a validated online tracker of mental health (the Computerized Adaptive Testing Depression Inventory, CAT-DI) together with other predictors of severity of symptoms could improve the accuracy of diagnosis and the effectiveness of treatment for depression. Digital phenotypes can be used to capture a large number of unique actions and behaviors that are difficult to record through interviews, and allow for continuous, high-resolution measurements. The study enrolled University of California Los Angeles (UCLA) students who were suffering from mild to severe depression symptoms. enrolled in the Screening and Treatment for Anxiety and Depression (STAND) program29 developed under the UCLA Depression Grand Challenge. Participants were referred to online assistance or in-person clinics in accordance with their severity of depression. Patients who scored high on the CAT-DI scale of 35 or 65 students were assigned online support via a coach and those with scores of 75 patients were referred to in-person clinical care for psychotherapy. Participants were asked a series questions at the beginning of the study regarding their demographics and psychosocial characteristics. The questions included education, age, sex and gender as well as financial status, marital status and whether they were divorced or not, their current suicidal thoughts, intent or attempts, as well as the frequency with which they consumed alcohol. Participants also rated their level of depression symptom severity on a scale of 0-100 using the CAT-DI. The CAT-DI test was conducted every two weeks for those who received online support and weekly for those who received in-person support. Predictors of the Reaction to Treatment Research is focusing on personalized treatment for depression. Many studies are focused on finding predictors, which can help doctors determine the most effective medications to treat each individual. Particularly, pharmacogenetics can identify genetic variations that affect how the body's metabolism reacts to antidepressants. Read the Full Posting enables doctors to choose medications that are likely to be most effective for each patient, while minimizing the time and effort in trial-and-error procedures and avoiding side effects that might otherwise hinder progress. Another promising approach is to develop prediction models that combine clinical data and neural imaging data. These models can then be used to determine the best combination of variables that are predictive of a particular outcome, such as whether or not a medication will improve the mood and symptoms. These models can be used to determine the response of a patient to a treatment, which will help doctors to maximize the effectiveness. A new generation of studies utilizes machine learning techniques, such as supervised learning and classification algorithms (like regularized logistic regression or tree-based techniques) to blend the effects of several variables and increase predictive accuracy. These models have been proven to be useful in predicting outcomes of treatment for example, the response to antidepressants. These approaches are becoming more popular in psychiatry and will likely become the norm in the future medical practice. In addition to ML-based prediction models research into the mechanisms that cause depression is continuing. Recent findings suggest that depression is related to dysfunctions in specific neural networks. This suggests that an individualized treatment for depression will be based on targeted therapies that restore normal functioning to these circuits. Internet-based-based therapies can be a way to accomplish this. They can offer a more tailored and individualized experience for patients. One study found that an internet-based program improved symptoms and led to a better quality of life for MDD patients. A controlled, randomized study of a customized treatment for depression revealed that a significant number of patients saw improvement over time and fewer side effects. Predictors of Side Effects In the treatment of depression the biggest challenge is predicting and identifying the antidepressant that will cause very little or no negative side negative effects. Many patients have a trial-and error method, involving various medications prescribed before finding one that is safe and effective. Pharmacogenetics offers a fresh and exciting method to choose antidepressant medications that is more efficient and targeted. A variety of predictors are available to determine the best antidepressant to prescribe, including genetic variants, phenotypes of patients (e.g. gender, sex or ethnicity) and comorbidities. To identify the most reliable and accurate predictors of a specific treatment, randomized controlled trials with larger numbers of participants will be required. This is due to the fact that it can be more difficult to detect moderators or interactions in trials that comprise only one episode per person instead of multiple episodes over a period of time. Additionally, the estimation of a patient's response to a particular medication is likely to require information on symptoms and comorbidities and the patient's previous experiences with the effectiveness and tolerability of the medication. Currently, only some easily identifiable sociodemographic and clinical variables seem to be reliable in predicting the severity of MDD like gender, age, race/ethnicity and SES, BMI, the presence of alexithymia and the severity of depressive symptoms. The application of pharmacogenetics to treatment for depression is in its early stages and there are many obstacles to overcome. First, a clear understanding of the underlying genetic mechanisms is needed as well as an understanding of what constitutes a reliable predictor for treatment response. In addition, ethical issues such as privacy and the ethical use of personal genetic information must be considered carefully. In the long-term the use of pharmacogenetics could provide an opportunity to reduce the stigma that surrounds mental health treatment and improve the outcomes of those suffering with depression. Like any other psychiatric treatment, it is important to take your time and carefully implement the plan. At present, the most effective course of action is to offer patients an array of effective medications for depression and encourage them to talk with their physicians about their experiences and concerns.
