Personalized Depression Treatment
Traditional therapy and medication don't work for a majority of patients suffering from depression. Personalized treatment may be the answer.
Cue is a digital intervention platform that transforms passively acquired sensor data from smartphones into customized micro-interventions designed to improve mental health. We analysed the best medication to treat anxiety and depression-fit personalized ML models for each subject using Shapley values to discover their feature predictors and reveal distinct features that are able to change mood as time passes.
Predictors of Mood
Depression is one of the most prevalent causes of mental illness.1 Yet, only half of those who have the disorder receive treatment1. In order to improve outcomes, clinicians need to be able to identify and treat depression patients with the highest chance of responding to certain treatments.
Personalized depression treatment can help. Researchers at the University of Illinois Chicago are developing new methods for predicting which patients will gain the most from certain treatments. They make use of mobile phone sensors as well as a voice assistant that incorporates artificial intelligence and other digital tools. With two grants awarded totaling over $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 conducted to the present has been focused on clinical and sociodemographic characteristics. These include demographics like age, gender and education as well as clinical aspects like symptom severity, comorbidities and biological markers.
While many of these aspects can be predicted from data in medical records, very few studies have employed longitudinal data to explore the causes of mood among individuals. Many studies do not take into consideration the fact that moods can differ significantly between individuals. Therefore, it is crucial to create methods that allow the determination of 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. This enables the team to develop algorithms that can identify distinct patterns of behavior and emotions that differ between individuals.
The team also created a machine-learning algorithm that can identify dynamic predictors of the mood of each person's depression. The algorithm combines these personal characteristics into a distinctive "digital phenotype" for each participant.
This digital phenotype was correlated with CAT-DI scores, a psychometrically validated severity scale for symptom severity. However the correlation was tinny (Pearson's r = 0.08, the BH-adjusted p-value was 3.55 x 10-03) and varied widely across individuals.
Predictors of symptoms
Depression is one of the leading causes of disability1 but is often underdiagnosed and undertreated2. In addition, a lack of effective interventions and stigma associated with depression disorders hinder many individuals from seeking help.
To facilitate personalized treatment in order to provide a more personalized treatment, identifying factors that predict the severity of symptoms is crucial. However, the current methods for predicting symptoms rely on clinical interview, which has poor reliability and only detects a tiny number of features that are associated with depression.2
Machine learning can enhance the accuracy of the diagnosis and treatment of depression by combining continuous, digital behavioral patterns gathered from sensors on smartphones along with a verified mental health tracker online (the Computerized Adaptive Testing Depression Inventory CAT-DI). Digital phenotypes permit continuous, high-resolution measurements and capture a variety of distinct behaviors and patterns that are difficult to record using interviews.
The study included University of California Los Angeles students with moderate to severe depression symptoms who were enrolled in the Screening and lithium treatment for depression uk for depression (sharp-bowen.technetbloggers.de) for Anxiety and Depression program29 developed as part of the UCLA Depression Grand Challenge. Participants were directed to online assistance or in-person clinics depending on their depression severity. Participants who scored a high on the CAT-DI scale of 35 65 students were assigned online support with the help of a coach. Those with scores of 75 patients were referred to in-person psychotherapy.
Participants were asked a series of questions at the beginning of the study concerning their demographics and psychosocial traits. These included sex, age education, work, and financial status; whether they were divorced, partnered or single; the frequency of 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. CAT-DI assessments were conducted each week for those who received online support and weekly for those receiving in-person care.
Predictors of Treatment Response
A customized treatment for depression is currently a major research area and many studies aim at identifying predictors that will allow clinicians to identify the most effective medications for each patient. Particularly, pharmacogenetics can identify genetic variants that determine how the body metabolizes antidepressants. This lets doctors select the medication that are likely to be the most effective for every patient, minimizing the time and effort needed for trial-and-error treatments and eliminating any adverse effects.
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 best combination of variables predictors of a specific outcome, like whether or not a drug is likely to improve the 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 treatment currently being administered.
A new type of research employs machine learning techniques such as 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 shown to be effective in predicting the outcome of treatment for example, the response to antidepressants. These models are getting more popular in psychiatry, and it is likely that they will become the norm for the future of clinical practice.
In addition to the ML-based prediction models research into the underlying mechanisms of depression is continuing. Recent findings suggest that depression is related to the malfunctions of certain neural networks. This theory 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 that can provide a more individualized and personalized experience for patients. One study found that a web-based program improved symptoms and improved quality of life for MDD patients. In addition, a controlled randomized study of a personalised approach to depression treatment showed steady improvement and decreased adverse effects in a significant proportion of participants.
Predictors of side effects
In the treatment of depression a major challenge is predicting and determining the antidepressant that will cause minimal or zero negative side effects. Many patients have a trial-and error method, involving several medications prescribed before finding one that is effective and tolerable. Pharmacogenetics provides a novel and exciting method to choose antidepressant drugs that are more effective and precise.
There are a variety of predictors that can be used to determine the antidepressant that should be prescribed, such as gene variations, phenotypes of the patient like gender or ethnicity and comorbidities. To determine the most reliable and reliable predictors for a particular treatment, randomized controlled trials with larger sample sizes will be required. This is because the identifying of interactions or moderators may be much more difficult in trials that focus on a single instance of treatment per patient instead of multiple sessions of treatment over time.
Additionally the prediction of a patient's response will likely require information on the severity of symptoms, comorbidities and the patient's own perception of the effectiveness and tolerability. At present, only a few easily identifiable sociodemographic and clinical variables seem to be correlated with the severity of MDD factors, including gender, age race/ethnicity, SES BMI and the presence of alexithymia, and the severity of depression symptoms.
Many issues remain to be resolved in the application of pharmacogenetics in the treatment of depression. First it is necessary to have a clear understanding of the underlying genetic mechanisms is essential, as is a clear definition of what is a reliable indicator of treatment response. Ethics such as privacy and the ethical use of genetic information must also be considered. The use of pharmacogenetics may, in the long run, reduce stigma surrounding treatments for mental illness and improve treatment outcomes. As with all psychiatric approaches it is crucial medicine to treat anxiety and depression give careful consideration and implement the plan. At present, it's ideal to offer patients a variety of medications for depression that are effective and urge patients to openly talk with their doctors.
