Personalized Depression Treatment For a lot of people suffering from depression, traditional therapies and medication are ineffective. Personalized treatment could be the answer. Cue is an intervention platform that transforms sensor data collected from smartphones into personalized micro-interventions for improving mental health. We parsed the best-fit personalized ML models for each subject using Shapley values to identify their feature predictors and reveal distinct characteristics that can be used to predict changes in mood over time. Predictors of Mood Depression is a major cause of mental illness in the world.1 Yet only half of those suffering from the condition receive treatment. In order to improve outcomes, clinicians need to be able to recognize and treat patients who have the highest likelihood of responding to particular treatments. Personalized depression treatment can help. Researchers at the University of Illinois Chicago are developing new methods to predict which patients will gain the most from specific treatments. They use sensors for mobile phones and a voice assistant incorporating artificial intelligence, and other digital tools. Two grants worth more than $10 million will be used to identify biological and behavioral indicators of response. The majority of research on factors that predict depression treatment effectiveness has been focused on sociodemographic and clinical characteristics. These include factors that affect the demographics such as age, sex and education, clinical characteristics such as the severity of symptoms and comorbidities and biological indicators such as neuroimaging and genetic variation. While depression therapy of these factors can be predicted from the information in medical records, very few studies have utilized longitudinal data to explore predictors of mood in individuals. Few studies also take into consideration the fact that mood can differ significantly between individuals. Therefore, it is crucial to develop methods that allow for the recognition of the individual differences in mood predictors and the effects of treatment. 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 create algorithms that can detect various patterns of behavior and emotions that vary between individuals. In addition to these modalities, the team also developed a machine-learning algorithm that models the dynamic factors that determine a person's depressed mood. The algorithm combines these personal differences into a unique “digital phenotype” for each participant. This digital phenotype was correlated with CAT DI scores which is a psychometrically validated symptom severity scale. The correlation was low however (Pearson r = 0,08, P-value adjusted for BH = 3.55 x 10 03) and varied greatly between individuals. Predictors of symptoms Depression is a leading cause of disability in the world1, but it is often not properly diagnosed and treated. Depressive disorders are often not treated because of the stigma that surrounds them and the lack of effective interventions. To aid in the development of a personalized treatment plan, identifying factors that predict the severity of symptoms is crucial. Current prediction methods rely heavily on clinical interviews, which aren't reliable and only detect a few features associated with depression. Machine learning can be used to blend continuous digital behavioral phenotypes captured by smartphone sensors and an online mental health tracker (the Computerized Adaptive Testing Depression Inventory CAT-DI) along with other indicators of severity of symptoms has the potential to improve diagnostic accuracy and increase treatment efficacy for depression. Digital phenotypes permit continuous, high-resolution measurements. They also capture a wide range of distinctive behaviors and activity patterns that are difficult to document with interviews. The study included University of California Los Angeles (UCLA) students who were suffering from moderate to severe depressive symptoms. enrolled in the Screening and Treatment for Anxiety and Depression (STAND) program29, which was developed under the UCLA Depression Grand Challenge. Participants were sent online for support or to clinical treatment according to the severity of their depression. Participants who scored a high on the CAT-DI scale of 35 65 were allocated online support via the help of a peer coach. those who scored 75 patients were referred for psychotherapy in person. At the beginning, participants answered a series of questions about their personal demographics and psychosocial characteristics. These included sex, age and education, as well as work and financial situation; whether they were divorced, married or single; the frequency of suicidal ideation, intent or attempts; and the frequency at that they consumed alcohol. Participants also rated their level of depression symptom severity on a scale ranging from 0-100 using the CAT-DI. The CAT-DI assessment was conducted every two weeks for participants who received online support, and weekly for those who received in-person assistance. Predictors of Treatment Response Research is focused on individualized depression treatment. Many studies are aimed at finding predictors that can help clinicians identify the most effective drugs to treat each patient. Pharmacogenetics, in particular, uncovers genetic variations that affect the way that our bodies process drugs. This lets doctors select the medication that will likely work best for each patient, reducing the amount of time and effort required for trials and errors, while avoiding any side effects. Another approach that is promising is to create predictive models that incorporate information from clinical studies and neural imaging data. These models can be used to determine which variables are the most likely to predict a specific outcome, like whether a medication can help with symptoms or mood. These models can be used to determine the response of a patient to a treatment, allowing doctors to maximize the effectiveness. A new generation of machines employs machine learning methods such as algorithms for classification and supervised learning such as regularized logistic regression, and tree-based methods to integrate the effects of several variables to improve the accuracy of predictive. These models have been proven to be useful for the prediction of treatment outcomes like the response to antidepressants. These models are getting more popular in psychiatry, and it is expected that they will become the norm for future clinical practice. Research into depression's underlying mechanisms continues, in addition to ML-based predictive models. Recent findings suggest that depression is related to the malfunctions of certain neural networks. This suggests that the treatment for depression will be individualized based on targeted therapies that target these circuits in order to restore normal function. Internet-based interventions are an effective method to achieve this. They can offer an individualized and tailored experience for patients. A study showed that an internet-based program helped improve 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 as well as fewer side consequences. Predictors of side effects A major obstacle in individualized depression treatment involves identifying and predicting the antidepressant medications that will have very little or no side effects. Many patients are prescribed various medications before finding a medication that is effective and tolerated. Pharmacogenetics provides a novel and exciting method of selecting antidepressant medicines that are more effective and specific. A variety of predictors are available to determine the best antidepressant to prescribe, including gene variants, patient phenotypes (e.g. sexual orientation, gender or ethnicity) and co-morbidities. To identify the most reliable and valid predictors for a specific treatment, controlled trials that are randomized with larger sample sizes will be required. This is due to the fact that it can be more difficult to detect the effects of moderators or interactions in trials that contain only one episode per participant instead of multiple episodes spread over a long period of time. Additionally the estimation of a patient's response to a particular medication will likely also need to incorporate information regarding symptoms and comorbidities in addition to the patient's prior subjective experience of its tolerability and effectiveness. There are currently only a few easily measurable sociodemographic variables as well as clinical variables appear to be consistently associated with response to MDD. These include gender, age, race/ethnicity, BMI, SES and the presence of alexithymia. The application of pharmacogenetics to depression treatment is still in its beginning stages, and many challenges remain. First is a thorough understanding of the genetic mechanisms is required as well as an understanding of what constitutes a reliable predictor for treatment response. In addition, ethical concerns such as privacy and the appropriate use of personal genetic information should be considered with care. In the long term pharmacogenetics can provide an opportunity to reduce the stigma associated with mental health care and improve treatment outcomes for those struggling with depression. As with any psychiatric approach it is essential to take your time and carefully implement the plan. For now, it is best to offer patients a variety of medications for depression that work and encourage patients to openly talk with their doctor.
