For many people gripped by depression, traditional therapy and medication isn't effective. Personalized treatment could be the solution.
Cue is an intervention platform that transforms sensors that are passively gathered from smartphones into personalized micro-interventions to improve mental health. We analyzed the best-fitting personalized ML models for each individual using Shapley values, in order to understand their characteristic predictors. This revealed distinct features that deterministically changed mood over time.
Predictors of Mood
Depression is among the leading causes of mental illness.1 However, only half of those who have the condition receive treatment1. In order to improve outcomes, healthcare professionals must be able to recognize and treat patients who have the highest chance of responding to certain treatments.
A customized depression treatment is one way to do this. Using sensors for mobile phones, an artificial intelligence voice assistant and other digital tools researchers at the University of Illinois Chicago (UIC) are working on new ways to determine which patients will benefit from the treatments they receive. 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 conducted to so far has focused on sociodemographic and clinical characteristics. These include demographics such as gender, age, and education, and clinical characteristics such as symptom severity and comorbidities as well as biological markers.
A few studies have utilized longitudinal data to predict mood in individuals. Many studies do not consider the fact that mood can vary significantly between individuals. Therefore, it is essential to develop methods that allow for the determination of the individual differences in mood predictors and the effects of treatment.
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 will then create algorithms to identify patterns of behavior and emotions that are unique to each individual.
The team also created an algorithm for machine learning to model dynamic predictors for each person's mood for depression. The algorithm combines these individual differences into a unique "digital phenotype" for each participant.
This digital phenotype was correlated with CAT-DI scores, a psychometrically validated symptom severity scale. The correlation was low, however (Pearson r = 0,08; BH adjusted P-value 3.55 x 10 03) and varied significantly between individuals.
Predictors of symptoms
Depression is a leading reason for disability across the world1, however, it is often untreated and misdiagnosed. Depression disorders are rarely treated because of the stigma attached to them and the lack of effective treatments.
To aid in the development of a personalized treatment plan in order to provide a more personalized treatment, identifying predictors of symptoms is important. However, current prediction methods rely on clinical interview, which is not reliable and only detects a tiny number of symptoms related to depression.2
Machine learning can increase the accuracy of the diagnosis and treatment of mild depression treatment by combining continuous, digital behavioral phenotypes collected from smartphone sensors along with a verified mental health tracker online (the Computerized Adaptive Testing Depression Inventory CAT-DI). Digital phenotypes can be used to are able to capture a variety of distinct actions and behaviors that are difficult to capture through interviews, and allow for continuous and high-resolution measurements.
The study included University of California Los Angeles students with moderate to severe depression symptoms who were taking part in the Screening and Treatment for Anxiety and Depression program29 developed as part of the UCLA Postnatal depression treatment Grand Challenge. Participants were referred to online support or to clinical treatment according to the degree of their depression. Participants with a CAT-DI score of 35 or 65 were assigned to online support with an online peer coach, whereas those with a score of 75 were routed to clinics in-person for psychotherapy.
At the beginning of the interview, participants were asked an array of questions regarding their personal characteristics and psychosocial traits. These included sex, age education, work, and financial status; whether they were divorced, partnered, or single; current suicidal ideation, intent or attempts; and the frequency at that they consumed alcohol. The CAT-DI was used to assess the severity of depression symptoms on a scale from zero to 100. The CAT DI assessment was conducted every two weeks for participants who received online support and weekly for those who received in-person assistance.
Predictors of Treatment Reaction
Personalized depression treatment is currently a research priority and many studies aim at identifying predictors that help clinicians determine the most effective drugs for each patient. Particularly, pharmacogenetics can identify genetic variations that affect how the body metabolizes antidepressants. This allows doctors to select the medications that are most likely to be most effective for each patient, reducing the time and effort in trial-and-error procedures and avoiding side effects that might otherwise slow advancement.
Another promising approach is building models of prediction using a variety of data sources, including clinical information and neural imaging data. These models can be used to determine the most effective combination of variables that are predictive of a particular outcome, such as whether or not a drug is likely to improve mood and symptoms. These models can also be used to predict the response of a patient to first line treatment for anxiety and depression that is already in place, allowing doctors to maximize the effectiveness of their treatment currently being administered.
A new generation employs machine learning methods such as supervised and classification algorithms, regularized logistic regression and tree-based methods to combine the effects of several variables to improve the accuracy of predictive. These models have proven to be effective in predicting treatment outcomes such as the response to antidepressants. These approaches are becoming more popular in psychiatry, and are likely to become the standard of future treatment.
Research into the underlying causes of depression continues, as do ML-based predictive models. Recent findings suggest that depression is linked to the malfunctions of certain neural networks. This theory suggests that a individualized treatment for depression will be based upon targeted therapies that restore normal functioning to these circuits.
One way to do this is to use internet-based interventions that can provide a more personalized and customized experience for patients. For instance, one study found that a program on the internet was more effective than standard care in improving symptoms and providing an improved quality of life for people with MDD. A controlled, randomized study of an individualized treatment for depression revealed that a significant percentage of patients saw improvement over time as well as fewer side negative effects.
Predictors of Side Effects
In the treatment of depression a major challenge is predicting and determining which antidepressant medication will have no or minimal side negative effects. Many patients are prescribed various medications before finding a medication that is both effective and well-tolerated. Pharmacogenetics provides a novel and exciting method of selecting antidepressant medicines that are more efficient and targeted.
Many predictors can be used to determine which antidepressant to prescribe, including genetic variants, patient phenotypes (e.g. gender, sex or ethnicity) and co-morbidities. To identify the most reliable and valid predictors of a specific treatment, randomized controlled trials with larger sample sizes will be required. This is because it could be more difficult to detect interactions or moderators in trials that contain only a single episode per person instead of multiple episodes over a period of time.
Additionally, predicting a patient's response will likely require information on the comorbidities, symptoms profiles and the patient's subjective experience of tolerability and effectiveness. Currently, only some easily assessable sociodemographic and clinical variables are believed to be reliably associated with the severity of MDD factors, including gender, age race/ethnicity, SES, BMI, the presence of alexithymia, and the severity of depressive symptoms.
The application of pharmacogenetics in treatment for depression treatment residential is in its infancy, and many challenges remain. first line treatment for anxiety and depression, a clear understanding of the underlying genetic mechanisms is needed, as is an understanding of what constitutes a reliable predictor for treatment response. Ethics, such as privacy, and the responsible use of genetic information are also important to consider. Pharmacogenetics can eventually help reduce stigma around treatments for mental illness and improve the quality of treatment. Like any other psychiatric treatment it is crucial to give careful consideration and implement the plan. At present, it's recommended to provide patients with a variety of medications for depression that are effective and urge them to talk openly with their physicians.
