Personalized Depression Treatment
Traditional therapies and medications are not effective for a lot of people suffering from depression. A customized treatment could be the answer.
Cue is an intervention platform for digital devices that translates passively acquired normal sensor data from smartphones into personalised micro-interventions to improve mental health. We analyzed the best-fitting personalized ML models to each person, using Shapley values to determine their characteristic predictors. This revealed distinct features that were deterministically changing mood over time.
Predictors of Mood
Depression is a leading cause of mental illness in the world.1 Yet the majority of people suffering from the condition receive treatment. To improve outcomes, healthcare professionals must be able to recognize and treat patients who have the highest likelihood of responding to specific treatments.
Personalized depression treatment is one way to do this. Researchers at the University of Illinois Chicago are developing new methods for predicting which patients will benefit most from certain treatments. They use sensors for mobile phones as well as a voice assistant that incorporates artificial intelligence as well as other digital tools. Two grants were awarded that total over $10 million, they will employ these tools to identify biological and behavioral predictors of the response to antidepressant medication and psychotherapy.
To date, the majority of research into predictors of depression treatment effectiveness has been focused on sociodemographic and clinical characteristics. These include demographics such as age, gender, and education, as well as clinical aspects such as symptom severity, comorbidities and biological markers.
While many of these variables can be predicted by the information available in medical records, few studies have used longitudinal data to study the causes of mood among individuals. A few studies also take into consideration the fact that moods can vary significantly between individuals. It is therefore important to develop methods which permit the identification and quantification of individual differences between mood predictors and treatment effects, for instance.
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. The team is able to develop algorithms to detect patterns of behavior and emotions that are unique to each person.
The team also devised a machine-learning algorithm that can model dynamic predictors for each person's depression mood. The algorithm blends these individual differences into a unique "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 weak, however (Pearson r = 0,08, P-value adjusted for BH = 3.55 10 03) and varied significantly among individuals.
Predictors of symptoms
Depression is the leading reason for disability across the world, but it is often untreated and misdiagnosed. Depression disorders are rarely treated due to the stigma associated with them, as well as the lack of effective interventions.
To help with personalized treatment, it is essential to identify the factors that predict symptoms. However, the current methods for predicting symptoms rely on clinical interview, which has poor reliability and only detects a limited number of symptoms related to depression.2
Machine learning can be used to blend continuous digital behavioral phenotypes of a person 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 could improve the accuracy of diagnosis and treatment efficacy for depression. Digital phenotypes permit continuous, high-resolution measurements. They also capture a wide variety of unique behaviors and activity patterns that are difficult to document using interviews.
The study comprised University of California Los Angeles students with mild to severe depression symptoms who were taking part in the Screening and Treatment for Anxiety and Depression program29 that was developed as part of the UCLA postpartum depression treatment Grand Challenge. Participants were sent online for support or to clinical treatment according to the degree of their depression. Those with a CAT-DI score of 35 65 were given online support with the help of a coach. Those with a score 75 patients were referred for psychotherapy in-person.
At the beginning, participants answered the answers to a series of questions concerning their personal demographics and psychosocial characteristics. The questions covered education, age, sex and gender as well as marital status, financial status as well as whether they divorced or not, current suicidal thoughts, intentions or attempts, and the frequency with which they consumed alcohol. Participants also rated their level of depression symptom severity on a 0-100 scale using the CAT-DI. CAT-DI assessments were conducted each other week for participants who received online support and every week for those who received in-person care.
Predictors of Treatment Response
Personalized depression treatment is currently a top research topic and many studies aim at identifying predictors that will allow clinicians to identify the most effective drugs for each patient. Pharmacogenetics, for instance, uncovers genetic variations that affect the way that our bodies process drugs. This allows doctors to select the medications that are most likely to be most effective for each patient, minimizing the time and effort involved in trial-and-error treatments and avoiding side effects that might otherwise hinder the progress of the patient.
Another approach that is promising is to build prediction models combining information from clinical studies and neural imaging data. These models can be used to determine the best antidepressant for treatment resistant depression combination of variables predictive of a particular outcome, like whether or not a medication is likely to improve symptoms and mood. These models can also be used to predict a patient's response to a treatment they are currently receiving, allowing doctors to maximize the effectiveness of the treatment currently being administered.
A new era of research employs machine learning techniques like supervised learning and classification algorithms (like regularized logistic regression or tree-based techniques) to blend the effects of several variables and increase predictive accuracy. These models have been proven to be effective in predicting treatment outcomes, such as response to antidepressants. These models are getting more popular in psychiatry and it is expected that they will become the norm lithium for treatment resistant depression the future of clinical practice.
Research into the underlying causes of depression continues, as do predictive models based on ML. Recent findings suggest that the disorder is linked with neurodegeneration in particular circuits. This suggests that individualized depression treatment will be based on targeted therapies that target these circuits to restore normal function.
Internet-delivered interventions can be an effective method to accomplish this. They can provide a more tailored and individualized experience for patients. For instance, one study found that a web-based program was more effective than standard treatment in alleviating symptoms and ensuring a better quality of life for patients suffering from MDD. Additionally, a randomized controlled study of a personalised approach to depression treatment showed sustained improvement and reduced adverse effects in a large proportion of participants.
Predictors of side effects
A major issue in personalizing depression treatment is predicting which antidepressant medications will cause very little or no side effects. Many patients experience a trial-and-error method, involving a variety of medications being prescribed before settling on one that is effective and tolerable. Pharmacogenetics is an exciting new method for an efficient and specific approach to choosing antidepressant medications.
There are many variables that can be used to determine which antidepressant should be prescribed, including gene variations, phenotypes of patients like gender or ethnicity, and comorbidities. To identify the most reliable and valid predictors for a particular treatment, controlled trials that are randomized with larger sample sizes will be required. This is because the detection of moderators or interaction effects could be more difficult in trials that focus on a single instance of treatment per participant instead of multiple episodes of treatment over a period of time.
Furthermore, the prediction of a patient's reaction to a particular medication is likely to require information on comorbidities and symptom profiles, as well as the patient's personal experience of its tolerability and effectiveness. Currently, only a few easily identifiable sociodemographic variables and clinical variables seem 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.
The application of pharmacogenetics to depression treatment is still in its early stages, and many challenges remain. First, it is essential to have a clear understanding and definition of the genetic factors that cause depression, as well as a clear definition of an accurate predictor of treatment response. Ethics like privacy, and the ethical use of genetic information should also be considered. Pharmacogenetics could eventually reduce stigma associated with mental health treatment and improve the outcomes of treatment. Like any other psychiatric treatment it is essential to take your time and carefully implement the plan. At present, it's ideal to offer patients a variety of medications for depression that are effective and encourage patients to openly talk with their doctor.
