Personalized Depression Treatment
For many suffering from depression, traditional therapies and medication isn't effective. A customized treatment could be the solution.
Cue is an intervention platform that transforms passively acquired sensor data from smartphones into personalised 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 with time.
Predictors of Mood
Depression is the leading cause of mental illness across the world.1 Yet the majority of people with the condition receive treatment. In order to improve outcomes, clinicians need to be able to identify and treat patients who have the highest probability of responding to certain treatments.
Personalized depression treatment can help. Researchers at the University of Illinois Chicago are developing new methods for predicting which patients will benefit most from specific treatments. They are using sensors for mobile phones, a voice assistant with artificial intelligence and other digital tools. Two grants were awarded that total over $10 million, they will make use of these techniques to determine biological and behavioral predictors of responses to antidepressant medications as well as psychotherapy.
The majority of research on factors that predict depression treatment effectiveness has been focused on clinical and sociodemographic characteristics. These include factors that affect the demographics such as age, sex and education, clinical characteristics including symptoms severity and comorbidities and biological indicators such as neuroimaging and genetic variation.
While many of these aspects can be predicted from information in medical records, only a few studies have used longitudinal data to determine the causes of mood among individuals. They have not taken into account the fact that moods vary significantly between individuals. Therefore, it is essential to create methods that allow the recognition of the individual differences in mood predictors and treatments effects.
The team's new approach uses daily, in-person evaluations of mood and lifestyle variables using a smartphone app called AWARE, a Cognitive treatment for depression evaluation with the BiAffect app and electroencephalography -- an imaging technique that monitors brain activity. This allows the team to develop algorithms that can detect various patterns of behavior and emotion that differ between individuals.
In addition to these methods, the team also developed a machine-learning algorithm to model the changing factors that determine a person's depressed mood. The algorithm combines these personal variations into a distinct "digital phenotype" for each participant.
This digital phenotype has been correlated with CAT DI scores, a psychometrically validated symptom severity scale. However the correlation was tinny (Pearson's r = 0.08, the BH-adjusted p-value was 3.55 1003) and varied widely across individuals.
Predictors of symptoms
seasonal depression treatment is among the world's leading causes of disability1 yet it is often untreated and not diagnosed. In addition an absence of effective treatments and stigmatization associated with depressive disorders prevent many people from seeking help.
To assist in individualized treatment, it is important to identify predictors of symptoms. However, the methods used to predict symptoms depend on the clinical interview which has poor reliability and only detects a tiny number of features related to depression.2
Using machine learning to combine continuous digital behavioral phenotypes that are captured by sensors on smartphones and a validated online tracker of mental health (the Computerized Adaptive Testing Depression Inventory, CAT-DI) with other predictors of symptom severity could improve the accuracy of diagnosis and the effectiveness of treatment for depression. Digital phenotypes can provide continuous, high-resolution measurements and capture a variety of distinct behaviors and patterns that are difficult to document through interviews.
The study involved University of California Los Angeles students who had mild to severe depression treatment private symptoms who were taking part in the Screening and Treatment for Anxiety and Depression program29 developed as part of the UCLA Depression Grand Challenge. Participants were referred to online support or in-person clinical care in accordance with their severity of depression. Patients who scored high on the CAT-DI scale of 35 65 were given online support by an instructor and those with a score 75 patients were referred to in-person clinical care for psychotherapy.
At the beginning, participants answered the answers to a series of questions concerning their personal demographics and psychosocial features. The questions asked included age, sex, and education and financial status, marital status, whether they were divorced or not, current suicidal thoughts, intentions or attempts, and how often they drank. Participants also rated their level of depression symptom severity on a 0-100 scale using the CAT-DI. CAT-DI assessments were conducted each week for those that received online support, and every week for those who received in-person treatment.
Predictors of Treatment Reaction
The development of a personalized depression treatment is currently a research priority, and many studies aim to identify predictors that help clinicians determine the most effective medication for each individual. Pharmacogenetics, for instance, is a method of identifying genetic variations that affect how the body's metabolism reacts to drugs. This allows doctors to select the medications that are most likely to be most effective for each patient, while minimizing the time and effort required in trial-and-error procedures and avoid any adverse effects that could otherwise slow the progress of the patient.
Another approach that is promising is to build predictive models that incorporate information from clinical studies and neural imaging data. These models can be used to determine the most appropriate combination of variables that are predictors of a specific outcome, such as whether or not a medication will improve mood and symptoms. These models can also be used to predict a patient's response to a treatment they are currently receiving and help doctors maximize the effectiveness of the current treatment.
A new generation of studies uses machine learning methods like supervised learning and classification algorithms (like regularized logistic regression or tree-based methods) to combine the effects of many variables to improve predictive accuracy. These models have been proven to be useful in predicting treatment outcomes like the response to antidepressants. These techniques are becoming increasingly popular in psychiatry and will likely become the norm in the future clinical practice.
Research into the underlying causes of depression pharmacological treatment continues, as well as ML-based predictive models. Recent research suggests that the disorder is connected with dysfunctions in specific neural circuits. This theory suggests that individualized bipolar depression treatment treatment will be built around targeted treatments that target these circuits to restore normal functioning.
One method of doing this is by using internet-based programs that offer a more personalized and customized experience for patients. For example, one study found that a web-based program was more effective than standard care in reducing symptoms and ensuring an improved quality of life for patients suffering from MDD. In addition, a controlled randomized trial of a personalized approach to depression treatment showed sustained improvement and reduced side effects in a significant number of participants.
Predictors of side effects
A major issue in personalizing depression treatment involves identifying and predicting which antidepressant medications will have very little or no side effects. Many patients take a trial-and-error approach, with a variety of medications being prescribed before settling on one that is effective and tolerable. Pharmacogenetics provides a novel and exciting way to select antidepressant drugs that are more efficient and targeted.
Several predictors may be used to determine which antidepressant to prescribe, including gene variants, patient phenotypes (e.g. sexual orientation, gender or ethnicity) and the presence of comorbidities. However, identifying the most reliable and accurate factors that can predict the effectiveness of a particular treatment will probably require randomized controlled trials with much larger samples than those typically enrolled in clinical trials. This is because it could be more difficult to identify the effects of moderators or interactions in trials that comprise only a single episode per person rather than multiple episodes over time.
In addition, predicting a patient's response will likely require information on the comorbidities, symptoms profiles and the patient's own perception of the effectiveness and tolerability. Currently, only some easily identifiable sociodemographic and clinical variables appear to be reliable in predicting response to MDD like gender, age race/ethnicity BMI and the presence of alexithymia and the severity of depression symptoms.
Many challenges remain in the use of pharmacogenetics for depression treatment. First, it is essential to have a clear understanding and definition of the genetic mechanisms that underlie depression, and an understanding of a reliable predictor of treatment response. Additionally, ethical issues like privacy and the appropriate use of personal genetic information must be considered carefully. Pharmacogenetics could, in the long run reduce stigma associated with mental health treatment and improve the quality of treatment. But, like any other psychiatric treatment, careful consideration and planning is required. For now, the best course of action is medicine to treat anxiety and depression provide patients with a variety of effective depression medication options and encourage them to talk openly with their doctors about their concerns and experiences.
