Personalized Depression Treatment
For many people gripped by depression, traditional therapy and medication isn't effective treatments for depression. A customized treatment may be the solution.
Cue is an intervention platform for digital devices that translates passively acquired normal 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 understand their feature predictors and reveal distinct characteristics that can be used to predict changes in mood with time.
Predictors of Mood
Depression is a major cause of mental illness in the world.1 Yet the majority of people with the condition receive treatment. In order to improve outcomes, doctors must be able to identify and treat patients who have the highest likelihood of responding to specific treatments.
The treatment of depression can be personalized to help. By using sensors on mobile phones and an artificial intelligence voice assistant, and other digital tools researchers at the University of Illinois Chicago (UIC) are developing new methods to determine which patients will benefit from which treatments. With two grants awarded totaling more than $10 million, they will employ these techniques to determine the biological and behavioral factors that determine the response to antidepressant medication and psychotherapy.
The majority of research conducted to date has focused on clinical and sociodemographic characteristics. These include demographics like gender, age and education, as well as clinical characteristics like symptom severity and comorbidities, as well as biological markers.
While many of these variables can be predicted by the information available in medical records, few studies have employed longitudinal data to determine predictors of mood in individuals. Many studies do not take into consideration the fact that mood can vary significantly between individuals. Therefore, it is 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. This enables the team to create algorithms that can detect distinct patterns of behavior and emotions that differ between individuals.
In addition to these modalities, the team created a machine learning algorithm to model the dynamic factors that determine a 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. The correlation was low however (Pearson r = 0,08; P-value adjusted by BH 3.55 x 10 03) and varied widely between individuals.
Predictors of symptoms
depression and treatment is a leading cause of disability around the world, but it is often misdiagnosed and untreated2. In addition, a lack of effective interventions and stigma associated with depressive disorders stop many from seeking treatment.
To assist in individualized treatment, it is crucial to identify predictors of symptoms. The current methods for predicting symptoms rely heavily on clinical interviews, which are unreliable and only detect a few symptoms associated with Menopause depression Treatment.
Using machine learning to combine continuous digital behavioral phenotypes that are captured by smartphone sensors and a validated online tracker of mental health (the Computerized Adaptive Testing Depression Inventory, CAT-DI) with other predictors of symptom severity can improve diagnostic accuracy and increase treatment efficacy for depression. Digital phenotypes can be used to capture a large number of distinct behaviors and activities, which are difficult to record through interviews and permit continuous and high-resolution measurements.
The study involved 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 that was developed as part of the UCLA Depression Grand Challenge. Participants were referred to online assistance or medical care based on the degree of their depression. Patients with a CAT DI score of 35 or 65 were allocated online support via the help of a peer coach. those who scored 75 patients were referred for psychotherapy in-person.
Participants were asked a series questions at the beginning of the study about their psychosocial and demographic characteristics as well as their socioeconomic status. These included sex, age education, work, and financial status; whether they were partnered, divorced or single; their current suicidal ideation, intent, or attempts; and the frequency at which they drank alcohol. Participants also scored their level of depression severity on a 0-100 scale using the CAT-DI. The CAT DI assessment was carried out every two weeks for participants who received online support, and weekly for those who received in-person care.
Predictors of Treatment Reaction
A customized treatment for depression is currently a major research area and a lot of studies are aimed at identifying predictors that enable clinicians to determine the most effective drugs for each patient. In particular, pharmacogenetics identifies genetic variants that determine how to treat depression and anxiety without medication the body metabolizes antidepressants. This lets doctors select the medication that are likely to be the most effective for every patient, minimizing the amount of time and effort required for trial-and-error treatments and avoiding any side consequences.
Another promising approach is to create prediction models that combine clinical data and neural imaging data. These models can then be used to determine the most appropriate combination of variables predictive of a particular outcome, such as whether or not a particular medication will improve mood and symptoms. These models can also be used to predict a patient's response to treatment that is already in place and help doctors maximize the effectiveness of their current therapy.
A new generation of studies utilizes machine learning techniques, such as supervised learning and classification algorithms (like regularized logistic regression or tree-based techniques) to combine the effects of many variables and improve the accuracy of predictive. These models have been shown to be useful in predicting treatment outcomes for example, the response to antidepressants. These models are getting more popular in psychiatry and it is likely that they will become the standard for future clinical practice.
In addition to ML-based prediction models, research into the mechanisms behind depression is continuing. Recent findings suggest that depression is related to dysfunctions in specific neural networks. This theory suggests that a individualized treatment for depression will be based on targeted therapies that restore normal functioning to these circuits.
One way to do this is through internet-delivered interventions which can offer an personalized and customized experience for patients. One study found that a web-based program improved symptoms and led to a better quality of life for MDD patients. 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 adverse effects
A major issue in personalizing depression treatment is predicting which antidepressant medications will have very little or no side effects. Many patients are prescribed various medications before finding a medication that is effective and tolerated. Pharmacogenetics is an exciting new way to take an efficient and specific method of selecting antidepressant therapies.
There are several predictors that can be used to determine the antidepressant to be prescribed, including gene variations, phenotypes of the patient such as gender or ethnicity, and the presence of comorbidities. However, identifying the most reliable and accurate predictors for a particular treatment is likely to require randomized controlled trials of much larger samples than those normally enrolled in clinical trials. This is because the detection of interaction effects or moderators may be much more difficult in trials that consider a single episode of treatment per participant, rather than multiple episodes of treatment over time.
Furthermore, the prediction of a patient's response to a specific medication is likely to require information on symptoms and comorbidities as well as the patient's previous experience with tolerability and efficacy. There are currently only a few easily measurable sociodemographic variables as well as clinical variables are reliable in predicting the response to MDD. These include age, gender and race/ethnicity, BMI, SES and the presence of alexithymia.
The application of pharmacogenetics to depression treatment is still in its early stages and there are many hurdles to overcome. First it is necessary to have a clear understanding of the underlying genetic mechanisms is required, as is a clear definition of what treatment is there for depression is a reliable predictor of treatment response. Ethics like privacy, and the responsible use of genetic information should also be considered. Pharmacogenetics can be able to, over the long term, reduce stigma surrounding mental health treatment and improve treatment outcomes. However, as with all approaches to psychiatry, careful consideration and planning is essential. At present, the most effective option is to provide patients with a variety of effective depression medications and encourage them to speak with their physicians about their experiences and concerns.
