Personalized Depression Treatment
Traditional therapies and medications don't work for a majority of people suffering from depression. Personalized treatment could be the answer.
Cue is a digital intervention platform that converts passively collected smartphone sensor data into personalized micro-interventions that improve mental health. We examined the most effective-fitting personalized ML models to each subject, using Shapley values, in order to understand their feature predictors. This revealed distinct features that changed mood in a predictable manner over time.
Predictors of Mood
Depression is a major cause of mental illness across the world.1 Yet, only half of those suffering from the condition receive treatment. To improve outcomes, clinicians need to be able to identify and treat patients who have the highest likelihood of responding to particular treatments.
Personalized depression treatment is one method to achieve this. By using mobile phone sensors as well as an artificial intelligence voice assistant and other digital tools researchers at the University of Illinois Chicago (UIC) are working on new ways to predict which patients will benefit from the treatments they receive. Two grants were awarded that total more than $10 million, they will use these technologies to identify the biological and behavioral factors that determine response to antidepressant medications and psychotherapy.
The majority of research to date has focused on clinical and sociodemographic characteristics. These include demographic factors such as age, gender and education, clinical characteristics such as symptoms severity and comorbidities and biological markers such as neuroimaging and genetic variation.
A few studies have utilized longitudinal data to predict mood of individuals. Few also take into account the fact that mood varies significantly between individuals. Therefore, it is important to develop methods that permit the determination and quantification of the personal 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. This allows the team to create algorithms that can systematically identify various patterns of behavior and emotions that differ between individuals.
The team also created a machine-learning algorithm that can create dynamic predictors for the mood of each person's depression. The algorithm combines 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. The correlation was not strong however (Pearson r = 0,08, P-value adjusted by BH 3.55 x 10 03) and varied significantly between individuals.
Predictors of symptoms
Depression is the leading cause of disability around the world1, however, it is often untreated and misdiagnosed. In addition an absence of effective interventions and stigma associated with depression disorders hinder many people from seeking help.
To help with personalized treatment, it is crucial to identify predictors of symptoms. However, the current methods for predicting symptoms depend on the clinical interview which is not reliable and only detects a limited number of symptoms related to depression treatment residential.2
Machine learning can enhance the accuracy of diagnosis and treatment for depression by combining continuous, digital behavioral phenotypes gathered from smartphones with a validated mental health tracker online (the Computerized Adaptive Testing Depression Inventory CAT-DI). Digital phenotypes permit continuous, high-resolution measurements and capture a variety of unique behaviors and activity patterns that are difficult to document through interviews.
The study involved University of California Los Angeles students with moderate to severe depression symptoms who were enrolled in the Screening and Treatment for Anxiety and Depression program29 that was developed as part of the UCLA depression treatment exercise Grand Challenge. Participants were referred to online support or in-person clinical treatment depending on their depression severity. Patients with a CAT DI score of 35 65 were assigned to online support via the help of a peer coach. those who scored 75 were sent to in-person clinical care for psychotherapy.
At baseline, participants provided the answers to a series of questions concerning their personal characteristics and psychosocial traits. The questions included age, sex and education as well as marital status, financial status, whether they were divorced or not, current suicidal thoughts, intent or attempts, as well as how often they drank. The CAT-DI was used for assessing the severity of alcohol depression treatment-related symptoms on a scale ranging from zero to 100. The CAT-DI test was conducted every two weeks for those who received online support and weekly for those who received in-person care.
Predictors of Treatment Reaction
Research is focused on individualized treatment for depression. Many studies are focused on identifying predictors, which will help clinicians identify the most effective medications for each person. Particularly, pharmacogenetics can identify genetic variants that influence the way that the body processes antidepressants. This allows doctors to select the medications that are most likely to be most effective for each patient, while minimizing the time and effort involved in trial-and-error procedures and eliminating any side effects that could otherwise hinder the progress of the patient.
Another promising approach is to create prediction models that combine the clinical data with neural imaging data. These models can then be used to identify the best combination of variables predictive of a particular outcome, such as whether or not a medication is likely to improve mood and symptoms. These models can also be used to predict a patient's response to an existing treatment which allows doctors to maximize the effectiveness of their treatment currently being administered.
A new generation of studies uses machine learning methods like supervised learning and classification algorithms (like regularized logistic regression or tree-based techniques) to blend the effects of several variables and improve the accuracy of predictive. These models have been proven to be useful in predicting the outcome of treatment, such as response to antidepressants. These methods are becoming more popular in psychiatry, and are likely to become the standard of future clinical practice.
Research into the underlying causes of depression continues, in addition to predictive models based on ML. Recent research suggests that the disorder is associated with dysfunctions in specific neural circuits. This theory suggests that individualized depression treatment will be based on targeted therapies that target these circuits in order to restore normal function.
One method of doing this is to use internet-based interventions which can offer an individualized and tailored experience for patients. For example, one study found that a web-based program was more effective than standard treatment in reducing symptoms and ensuring the best quality of life for people with MDD. A randomized controlled study of a personalized treatment for depression treatment cbt (peatix.Com) found that a significant percentage of patients saw improvement over time and fewer side negative effects.
Predictors of Side Effects
A major challenge in personalized depression treatment involves identifying and predicting which antidepressant medications will cause very little or no side effects. Many patients have a trial-and error approach, with several medications being prescribed before settling on one that is safe and effective. Pharmacogenetics offers a new and exciting method of selecting antidepressant drugs that are more effective and specific.
A variety of predictors are available to determine which antidepressant is best to prescribe, including genetic variants, patient phenotypes (e.g., sex or ethnicity) and co-morbidities. However finding the most reliable and valid predictive factors for a specific treatment will probably require randomized controlled trials of significantly larger numbers of participants than those typically enrolled in clinical trials. This is because it could be more difficult to detect interactions or moderators in trials that contain only one episode per participant instead of multiple episodes over time.
Furthermore to that, predicting a patient's reaction will likely require information about the severity of symptoms, comorbidities and the patient's personal perception of effectiveness and tolerability. Presently, only a handful of easily assessable sociodemographic and clinical variables seem to be reliable in predicting response to MDD like age, gender race/ethnicity, SES, BMI, the presence of alexithymia and the severity of depressive symptoms.
Many issues remain to be resolved when it comes to the use of pharmacogenetics for depression treatment. First, a clear understanding of the genetic mechanisms is essential as well as an understanding of what is a reliable predictor of treatment response. Ethics such as privacy and the responsible use of genetic information must also be considered. Pharmacogenetics could, in the long run help reduce stigma around treatments for mental illness and improve the outcomes of treatment. But, like any approach to psychiatry careful consideration and implementation is required. For now, the best course of action is to offer patients an array of effective depression medications and encourage them to speak openly with their doctors about their experiences and concerns.
