Personalized Depression Treatment

For many suffering from depression, traditional therapy and medication isn't effective. Personalized treatment could be the solution.

Cue is an intervention platform that converts sensor data collected 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 features that deterministically change mood as time passes.

Predictors of Mood

Depression is a leading cause of mental illness across the world.1 Yet the majority of people suffering from the condition receive treatment. To improve outcomes, clinicians need to be able to recognize and treat patients with the highest likelihood of responding to certain treatments.

A customized depression treatment is one method of doing this. Using sensors on mobile phones as well as an artificial intelligence voice assistant and other digital tools researchers at the University of Illinois Chicago (UIC) are developing new methods to predict which patients will benefit from which treatments. Two grants worth more than $10 million will be used to determine biological and behavioral indicators of response.

So far, the majority of research into predictors of depression treatment effectiveness (Read A great deal more) has been focused on sociodemographic and clinical characteristics. These include demographic factors such as age, gender and education, clinical characteristics including symptom severity and comorbidities, and biological markers like neuroimaging and genetic variation.

A few studies have utilized longitudinal data to determine mood among individuals. Many studies do not consider the fact that moods can vary significantly between individuals. It is therefore important to develop methods that permit the determination and quantification of the personal 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 enables the team to create algorithms that can systematically identify various patterns of behavior and emotions that are different between people.

In addition to these modalities the team created a machine learning algorithm to model the changing predictors of each person's depressed mood. The algorithm combines these personal characteristics into a distinctive "digital phenotype" for each participant.

This digital phenotype has been associated with CAT DI scores, a psychometrically validated symptom severity scale. However the correlation was tinny (Pearson's r = 0.08, adjusted BH-adjusted P-value of 3.55 x 10-03) and varied widely among individuals.

Predictors of symptoms

Depression is the leading reason for disability across the world1, but it is often misdiagnosed and untreated2. In addition the absence of effective treatments and stigmatization associated with depression treatment plan cbt disorders hinder many people from seeking help.

To aid in the development of a personalized treatment plan, identifying patterns that can predict symptoms is essential. However, the current methods for predicting symptoms depend on the clinical interview which is not reliable and only detects a limited number of features that are associated with depression.2

Machine learning can be used to integrate continuous digital behavioral phenotypes captured by sensors on smartphones and an online tracker of mental health (the Computerized Adaptive Testing Depression Inventory, CAT-DI) with other predictors of symptom severity can improve the accuracy of diagnosis and treatment efficacy for depression. Digital phenotypes can provide continuous, high-resolution measurements as well as capture a wide range of distinctive behaviors and activity patterns that are difficult to record through interviews.

The study comprised University of California Los Angeles students who had mild depression treatments to severe depression symptoms who were enrolled in the Screening and Treatment for Anxiety and Depression program29 developed as part of the UCLA Depression Grand Challenge. Participants were routed to online support or in-person clinical care in accordance with their severity of depression. Participants who scored a high on the CAT DI of 35 65 were assigned to online support via an online peer coach, whereas those who scored 75 patients were referred to psychotherapy in person.

At baseline, participants provided the answers to a series of questions concerning their personal demographics and psychosocial features. These included sex, age and education, as well as work and financial situation; whether they were partnered, divorced or single; the frequency of suicidal thoughts, intentions, or attempts; and the frequency at which they drank alcohol. Participants also rated their degree of depression symptom severity on a scale ranging from 0-100 using the CAT-DI. The CAT-DI test was carried out every two weeks for those who received online support, and weekly for those who received in-person assistance.

Predictors of Treatment Response

Research is focusing on personalization of depression treatment. Many studies are aimed at identifying predictors, which will aid clinicians in identifying the most effective drugs to treat each patient. Pharmacogenetics, for instance, is a method of identifying genetic variations that affect the way that our bodies process drugs. This enables doctors to choose the medications that are most likely to be most effective for each patient, reducing the time and effort required in trial-and-error treatments and eliminating any side effects that could otherwise hinder advancement.

Another approach that is promising is to build models of prediction using a variety of data sources, combining the clinical information with neural imaging data. These models can then be used to identify the best combination of variables that is predictive of a particular outcome, such as whether or not a drug is likely to improve symptoms and mood. These models can be used to determine the patient's response to a treatment they are currently receiving which allows doctors to maximize the effectiveness of the current therapy.

A new type of research utilizes machine learning techniques, such as supervised learning and classification algorithms (like regularized logistic regression or tree-based methods) to combine the effects of multiple variables and increase predictive accuracy. These models have shown to be useful for forecasting treatment outcomes, such as the response to antidepressants. These models are getting more 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 research into the underlying mechanisms of depression is continuing. Recent findings suggest that depression is connected to the dysfunctions of specific neural networks. This theory suggests that an individualized treatment for depression will be based on targeted therapies that restore normal functioning to these circuits.

Internet-delivered interventions can be an option to accomplish this. They can provide a more tailored and individualized experience for patients. One study found that a program on the internet was more effective than standard treatment in alleviating symptoms and ensuring a better quality of life for people with MDD. A randomized controlled study of a customized treatment lithium for treatment resistant depression depression found that a significant percentage of participants experienced sustained improvement and fewer side negative effects.

Predictors of side effects

In the treatment of depression, a major challenge is predicting and identifying which antidepressant medications will have no or minimal negative side negative effects. Many patients take a trial-and-error method, involving a variety of medications being prescribed before settling on one that is effective and tolerable. Pharmacogenetics offers a fascinating new avenue for a more effective and precise method of selecting antidepressant therapies.

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. However, identifying the most reliable and reliable predictive factors for a specific treatment is likely to require randomized controlled trials with much larger samples than those that are typically part of clinical trials. This is because the identifying of interaction effects or moderators may be much more difficult in trials that focus on a single instance of treatment per person instead of multiple episodes of treatment over a period of time.

Additionally the prediction of a patient's reaction to a particular medication is likely to need to incorporate information regarding symptoms and comorbidities as well as the patient's previous experience with tolerability and efficacy. Presently, only a handful of easily measurable sociodemographic and clinical variables appear to be reliably associated with response to MDD factors, including age, gender, race/ethnicity and SES BMI, the presence of alexithymia and the severity of depression symptoms.

The application of pharmacogenetics to depression treatment is still in its early stages and there are many obstacles to overcome. First, a clear understanding of the underlying genetic mechanisms is essential and an understanding of what is a reliable predictor of natural treatment for depression response. In addition, ethical issues such as privacy and the responsible use of personal genetic information must be carefully considered. Pharmacogenetics can eventually, reduce stigma surrounding mental health natural treatment for anxiety and depression and improve treatment outcomes. As with all psychiatric approaches it is essential to take your time and carefully implement the plan. At present, it's best to offer patients various depression medications that are effective and encourage them to speak openly with their doctor.
