Personalized Depression Treatment
Traditional treatment and medications don't work for a majority of people who are depressed. A customized treatment could be the solution.
Cue is a digital intervention platform that converts passively collected sensor data from smartphones into personalised micro-interventions designed to improve mental health. We analyzed the most effective-fit personal ML models for each subject using Shapley values to identify their feature predictors and uncover distinct characteristics that can be used to predict changes in mood with time.
Predictors of Mood
untreatable depression is a major cause of mental illness across the world.1 Yet the majority of people suffering from the condition receive treatment. To improve the outcomes, healthcare professionals must be able to identify and treat patients who have the highest probability of responding to certain treatments.
Personalized depression treatment near me treatment is one method of doing this. 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. With two grants totaling more than $10 million, they will employ these technologies to identify biological and behavioral predictors of responses to antidepressant medications as well as psychotherapy.
So far, the majority of research on factors that predict depression treatment effectiveness has been focused on sociodemographic and clinical characteristics. These include demographics such as age, gender and education as well as clinical characteristics like severity of symptom and comorbidities as well as biological markers.
While many of these aspects can be predicted from the information in medical records, only a few studies have used longitudinal data to determine the factors that influence mood in people. Many studies do not consider the fact that mood can be very different between individuals. Therefore, it is crucial to develop methods that permit the recognition of individual differences in mood predictors and treatment effects.
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 develop algorithms that can detect distinct patterns of behavior and emotions that are different between people.
The team also created an algorithm for machine learning to identify dynamic predictors of the mood of each person's depression. The algorithm blends the individual characteristics to create an individual "digital genotype" for each participant.
This digital phenotype was associated with CAT DI scores that are a psychometrically validated symptoms severity scale. However, the correlation was weak (Pearson's r = 0.08, BH-adjusted P-value of 3.55 x 10-03) and varied widely among individuals.
Predictors of symptoms
Depression is one of the leading causes of disability1 but is often not properly diagnosed and treated. Depression disorders are usually not treated because of the stigma that surrounds them and the absence of effective interventions.
To assist in individualized treatment, it is essential to identify predictors of symptoms. However, current prediction methods depend on the clinical interview which is unreliable and only detects a tiny number of symptoms related to depression.2
Machine learning can increase the accuracy of diagnosis and treatment for depression by combining continuous, digital behavioral phenotypes collected from smartphone sensors with a validated mental health tracker online (the Computerized Adaptive Testing Depression Inventory CAT-DI). Digital phenotypes can be used to capture a large number of distinct behaviors and activities that are difficult to record through interviews and permit continuous, high-resolution measurements.
The study included University of California Los Angeles students with moderate to severe psychotic depression treatment symptoms who were taking part in the Screening and Treatment for Anxiety and Depression program29 that was developed as part of the UCLA Depression Grand Challenge. Participants were routed to online support or in-person clinical treatment according to the severity of their depression. Patients who scored high on the CAT-DI scale of 35 or 65 were assigned online support via a coach and those with scores of 75 patients were referred to psychotherapy in-person.
Participants were asked a series of questions at the beginning of the study regarding their demographics and psychosocial characteristics. The questions asked included age, sex and education as well as marital status, financial status as well as whether they divorced or not, the frequency of suicidal thoughts, intentions or attempts, and the frequency with which they consumed alcohol. Participants also scored their level of depression severity on a 0-100 scale using the CAT-DI. The CAT-DI test was conducted every two weeks for participants who received online support, and weekly for those who received in-person support.
Predictors of Treatment Response
A customized treatment for depression is currently a research priority, and many studies aim to identify predictors that allow clinicians to identify the most effective medication for each person. Pharmacogenetics, in particular, is a method of identifying genetic variations that affect how the human body metabolizes drugs. This allows doctors to select the medications that are most likely to work best for each patient, while minimizing the time and effort in trial-and-error treatments and eliminating any side effects that could otherwise hinder progress.
Another promising method is to construct prediction models using multiple data sources, such as clinical information and neural imaging data. These models can be used to determine the variables that are most likely to predict a specific outcome, like whether a medication will help with symptoms or mood. These models can be used to predict the response of a patient to a treatment, allowing doctors maximize the effectiveness.
A new generation of machines employs machine learning methods such as the supervised and classification algorithms, regularized logistic regression and tree-based methods to integrate the effects from multiple variables and increase the accuracy of predictions. These models have been proven to be useful in the prediction of treatment outcomes like the response to antidepressants. These approaches are becoming more popular in psychiatry, and are likely to be the norm in future treatment for panic attacks and depression.
The study of depression's underlying mechanisms continues, as well as predictive models based on ML. Recent research suggests that the disorder is connected with neural dysfunctions that affect specific circuits. This suggests that an individualized treatment for depression will be based upon targeted therapies that restore normal function to these circuits.
One method of doing this is by using internet-based programs which can offer an individualized and personalized 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 personalized treatment for depression found that a substantial percentage of patients saw improvement over time and had fewer adverse effects.
Predictors of Side Effects
In the treatment of depression the biggest challenge is predicting and determining the antidepressant that will cause very little or no adverse effects. Many patients are prescribed various drugs before they find a drug that is both effective and well-tolerated. Pharmacogenetics offers a new and exciting method to choose antidepressant drugs that are more efficient and targeted.
Many predictors can be used to determine which antidepressant is best to prescribe, such as gene variations, phenotypes of patients (e.g. gender, sex or ethnicity) and co-morbidities. However finding the most reliable and valid predictors for a particular treatment is likely to require randomized controlled trials of considerably larger samples than those normally enrolled in clinical trials. This is due to the fact that the identification of moderators or interaction effects could be more difficult in trials that only take into account a single episode of treatment per participant instead of multiple sessions of treatment over a period of time.
Furthermore, predicting a patient's response will likely require information on comorbidities, symptom profiles and the patient's personal perception of effectiveness and tolerability. There are currently only a few easily identifiable sociodemographic variables and clinical variables appear to be reliable in predicting the response to MDD. These include gender, age, race/ethnicity as well as BMI, SES and the presence of alexithymia.
Many issues remain to be resolved in the use of pharmacogenetics in the treatment of depression. It is crucial to have a clear understanding and definition of the genetic mechanisms that cause depression, as well as an accurate definition of a reliable predictor of treatment response. Additionally, ethical issues like privacy and the responsible use of personal genetic information should be considered with care. Pharmacogenetics can, in the long run reduce stigma associated with mental health treatment and improve treatment outcomes. As with any psychiatric approach it is crucial to give careful consideration and implement the plan. For now, it is ideal to offer patients an array of depression medications that are effective and encourage them to speak openly with their physicians.
