Personalized Depression Treatment
Traditional therapies and medications are not effective for a lot of people suffering from depression. Personalized treatment may be the answer.
Cue is a digital intervention platform that transforms passively acquired smartphone sensor data into personalized micro-interventions designed to improve mental health. We examined the most effective-fitting personalized ML models to each person using Shapley values, in order to understand their characteristic predictors. This revealed distinct features that changed mood in a predictable manner over time.
Predictors of Mood
Depression is among the leading causes of mental illness.1 However, only about half of people suffering from the condition receive treatment1. To improve outcomes, doctors must be able to identify and treat patients who have the highest chance of responding to certain treatments.
A customized depression treatment is one method of doing this. Researchers at the University of Illinois Chicago are developing new methods for predicting which patients will benefit the most from certain treatments. They make use of sensors for mobile phones and a voice assistant incorporating artificial intelligence and other digital tools. Two grants were awarded that total more than $10 million, they will employ these tools to identify biological and behavioral predictors of response to antidepressant medications and psychotherapy.
To date, the majority of research on predictors for depression treatment effectiveness has been focused on clinical and sociodemographic characteristics. These include demographics such as gender, age and education, as well as clinical aspects like severity of symptom and comorbidities, as well as biological markers.
While many of these aspects can be predicted from information available in medical records, few studies have employed longitudinal data to study the causes of mood among individuals. A few studies also consider the fact that moods can vary significantly between individuals. Therefore, it is important to develop methods which permit the determination and quantification of the individual differences in mood predictors, treatment effects, 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 create algorithms that can identify different patterns of behavior and emotions that vary between individuals.
The team also devised a machine-learning algorithm that can create dynamic predictors for the mood of each person's depression. The algorithm blends these individual variations into a distinct "digital phenotype" for each participant.
The digital phenotype was associated with CAT DI scores, a psychometrically validated severity scale for symptom severity. The correlation was not strong however (Pearson r = 0,08, BH adjusted P-value 3.55 10 03) and varied widely among individuals.
Predictors of symptoms
Depression is among the world's leading causes of disability1 but is often untreated and not diagnosed. Depressive disorders are often not treated because of the stigma attached to them and the absence of effective treatments.
To assist in individualized treatment, it is essential to identify predictors of symptoms. However, the current methods for predicting symptoms rely on clinical interview, which has poor reliability and only detects a limited number of features that are associated with depression.2
Machine learning is used to blend continuous digital behavioral phenotypes captured by smartphone sensors and a validated online mental health tracker (the Computerized Adaptive Testing Depression Inventory, CAT-DI) along with other indicators of severity of symptoms can increase the accuracy of diagnostics and the effectiveness of electromagnetic treatment for depression for depression. Digital phenotypes can provide continuous, high-resolution measurements as well as capture a wide variety of distinctive behaviors and activity patterns that are difficult to record using interviews.
The study included University of California Los Angeles students who had mild to severe depression symptoms who were taking part in the Screening and Treatment for Anxiety and Depression program29, which was developed as part of the UCLA Depression Grand Challenge. Participants were routed to online support or in-person clinical treatment depending on their depression severity. Those with a CAT-DI score of 35 65 were allocated online support via a peer coach, while those who scored 75 were routed to in-person clinical care for psychotherapy.
Participants were asked a series of questions at the beginning of the study about their demographics and psychosocial traits. The questions included education, age, sex and gender and marital status, financial status as well as whether they divorced or not, current suicidal ideas, intent or attempts, as well as the frequency with which they consumed alcohol. The CAT-DI was used to assess the severity of depression-related symptoms on a scale from 100 medicines to treat depression. CAT-DI assessments were conducted every week for those that received online support, and weekly for those receiving in-person care.
Predictors of the Reaction to Treatment
A customized treatment for depression is currently a major research area and a lot of studies are aimed to identify predictors that enable clinicians to determine the most effective drugs for each patient. Pharmacogenetics in particular identifies genetic variations that determine how the body's metabolism reacts to drugs. This lets doctors select the medication that are most likely to work for every patient, minimizing time and effort spent on trial-and error treatments and avoid any negative side effects.
Another promising approach is to build prediction models combining information from clinical studies and neural imaging data. These models can be used to identify which variables are the most predictive of a particular outcome, like whether a drug will improve symptoms or mood. These models can be used to determine a patient's response to an existing treatment, allowing doctors to maximize the effectiveness of the current therapy.
A new generation employs machine learning techniques like the supervised and classification algorithms, regularized logistic regression and tree-based techniques to combine the effects from multiple variables and improve predictive accuracy. These models have been demonstrated to be useful in predicting treatment outcomes for example, the response to antidepressants. These methods are becoming popular in psychiatry, and it is likely that they will become the norm for the future of clinical practice.
In addition to prediction models based on ML The study of the mechanisms that cause depression continues. Recent findings suggest meds that treat anxiety and depression the disorder is linked with dysfunctions in specific neural circuits. This theory suggests that a individualized treatment for depression will depend on targeted therapies that restore normal function to these circuits.
One method to achieve this is to use internet-based interventions which can offer an personalized and customized experience for patients. For example, one study found that a program on the internet was more effective than standard treatment in alleviating symptoms and ensuring an improved quality of life for people with MDD. Furthermore, a randomized controlled study of a personalised magnetic treatment for depression for perimenopause depression treatment demonstrated sustained improvement and reduced adverse effects in a significant number of participants.
Predictors of side effects
A major challenge in personalized depression treatment is predicting the antidepressant medications that will have minimal or no side effects. Many patients are prescribed various medications before finding a medication that is effective and tolerated. Pharmacogenetics is an exciting new avenue for a more efficient and targeted approach to choosing antidepressant medications.
A variety of predictors are available to determine which antidepressant is best to prescribe, including genetic variants, phenotypes of patients (e.g. sexual orientation, gender or ethnicity) and the presence of comorbidities. However, identifying the most reliable and accurate predictors for a particular treatment is likely to require randomized controlled trials with much larger samples than those normally enrolled in clinical trials. This is because it may be more difficult to determine interactions or moderators in trials that only include one episode per participant rather than multiple episodes over a period of time.
Additionally the estimation of a patient's response to a specific medication will likely also require information on comorbidities and symptom profiles, in addition to the patient's previous experience with tolerability and efficacy. Currently, only a few easily identifiable sociodemographic variables and clinical variables are reliably related to response to MDD. These include gender, age, race/ethnicity, SES, BMI and the presence of alexithymia.
The application of pharmacogenetics in treatment for depression is in its infancy, and many challenges remain. First is a thorough understanding of the underlying genetic mechanisms is essential and a clear definition of what is a reliable predictor of treatment response. Ethics like privacy, and the responsible use genetic information are also important to consider. In the long term pharmacogenetics can be a way to lessen the stigma that surrounds mental health electric treatment for depression and improve treatment outcomes for those struggling with depression. However, as with any other psychiatric treatment, careful consideration and application is essential. The best method is to provide patients with various effective depression medication options and encourage them to talk openly with their doctors about their experiences and concerns.
