Personalized Depression Treatment
Traditional therapy and medication are not effective for a lot of people who are depressed. Personalized treatment could be the solution.
Cue is an intervention platform that transforms sensor data collected from smartphones into personalized micro-interventions to improve mental health. We parsed the best-fit personalized ML models for each subject using Shapley values to understand their predictors of feature and reveal distinct characteristics that can be used to predict changes in mood over time.
Predictors of Mood
Depression is one of the leading causes of mental illness.1 However, only half of people suffering from the condition receive treatment1. To improve outcomes, healthcare professionals must be able identify and treat patients most likely to respond to specific treatments.
Personalized depression treatment is one method of doing this. Utilizing mobile phone sensors, 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 the treatments they receive. With two grants totaling over $10 million, they will employ these techniques to determine the biological and behavioral factors that determine the response to antidepressant medication and psychotherapy.
So far, the majority of research on factors that predict depression lithium treatment for depression effectiveness [This Web page] has been focused on clinical and sociodemographic characteristics. These include demographics like age, gender and education and clinical characteristics like symptom severity, comorbidities and biological markers.
While many of these variables can be predicted by the data in medical records, only a few studies have utilized longitudinal data to study the causes of mood among individuals. Many studies do not take into consideration the fact that mood can vary significantly between individuals. Therefore, it is essential to create methods that allow the determination of the individual differences in mood predictors and treatments effects.
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 identify various patterns of behavior and emotion that are different between people.
In addition to these modalities, the team also developed a machine-learning algorithm to model the dynamic variables that influence each person's mood. The algorithm blends these individual variations into a distinct "digital phenotype" for each participant.
This digital phenotype was found to be associated with CAT-DI scores, which is a psychometrically validated scale for assessing severity of symptom. The correlation was weak however (Pearson r = 0,08, P-value adjusted by BH 3.55 10 03) and varied widely between individuals.
Predictors of symptoms
Depression is one of the world's leading causes of disability1 but is often underdiagnosed and undertreated2. Depressive disorders are often not treated because of the stigma attached to them and the lack of effective treatments.
To help with personalized treatment, it is crucial to identify the factors that predict symptoms. However, current prediction methods depend on the clinical interview which is unreliable and only detects a limited number of features related to depression.2
Machine learning can be used to blend continuous digital behavioral phenotypes captured through smartphone sensors and an online mental health tracker (the Computerized Adaptive Testing Depression Inventory the CAT-DI) along with other indicators of symptom severity can improve the accuracy of diagnosis and the effectiveness of treatment for depression. These digital phenotypes are able to capture a variety of distinct behaviors and activities that are difficult to record through interviews, and allow for high-resolution, continuous measurements.
The study involved University of California Los Angeles students with mild to severe depression symptoms who were participating in the Screening and Treatment for Anxiety and Depression program29 developed as part of the UCLA Depression Grand Challenge. Participants were directed to online support or clinical care based on the degree of their depression. Patients who scored high on the CAT DI of 35 or 65 were assigned online support via a coach and those with scores of 75 patients were referred to in-person clinics for psychotherapy.
Participants were asked a series of questions at the beginning of the study concerning their demographics and psychosocial traits. These included age, sex, 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 rated their degree of depression symptom severity on a scale of 0-100 using the CAT-DI. CAT-DI assessments were conducted each other week for participants that received online support, and weekly for those receiving in-person care.
Predictors of Treatment Reaction
Research is focusing on personalized depression treatment facility near me treatment. Many studies are focused on finding predictors that can aid clinicians in identifying the most effective medications to treat each patient. Pharmacogenetics, in particular, is a method of identifying genetic variations that affect the way that our bodies process drugs. This allows doctors select medications that will likely work best for each patient, reducing the amount of time and effort required for trials and errors, while avoid any negative side consequences.
Another approach that is promising is to create predictive models that incorporate clinical data and neural imaging data. These models can be used to identify the variables that are most predictive of a particular outcome, like whether a medication can improve mood or symptoms. These models can be used to determine the patient's response to a treatment, allowing doctors maximize the effectiveness.
A new generation uses machine learning techniques like the supervised and classification algorithms such as regularized logistic regression, and tree-based methods to integrate the effects from multiple variables to improve the accuracy of predictive. These models have been proven to be useful for predicting treatment outcomes such as the response to antidepressants. These methods are becoming more popular in psychiatry and will likely become the norm in the future medical practice.
In addition to ML-based prediction models, research into the mechanisms behind depression is continuing. Recent findings suggest that the disorder is associated with dysfunctions in specific neural circuits. This suggests that the treatment for depression will be individualized based on targeted therapies that target these circuits in order to restore normal function.
One way to do this is by using internet-based programs that can provide a more individualized and personalized experience for patients. A study showed that an internet-based program improved symptoms and improved quality life for MDD patients. A randomized controlled study of a personalized treatment for depression revealed that a substantial percentage of patients experienced sustained improvement and had fewer adverse consequences.
Predictors of Side Effects
A major obstacle in individualized depression treatment involves identifying and predicting which antidepressant medications will cause the least amount of side effects or none at all. Many patients have a trial-and error approach, using various medications being prescribed before settling on one that is effective and tolerable. Pharmacogenetics provides an exciting new way to take an efficient and targeted method of selecting antidepressant therapies.
There are several predictors that can be used to determine which antidepressant should be prescribed, including gene variations, phenotypes of the patient such as ethnicity or gender and the presence of comorbidities. However, identifying the most reliable and valid predictive factors for a specific treatment is likely to require randomized controlled trials with much larger samples than those normally enrolled in clinical trials. This is because it may be more difficult to determine the effects of moderators or interactions in trials that contain only one episode per person rather than multiple episodes over a period of time.
Additionally, the prediction of a patient's response to a specific medication will likely also require information about symptoms and comorbidities as well as the patient's previous experience with tolerability and efficacy. At present, only a handful of easily identifiable sociodemographic variables and clinical variables appear to be consistently associated with response to MDD. These include gender, age, race/ethnicity, SES, BMI and the presence of alexithymia.
Many challenges remain in the application of pharmacogenetics to treat depression treatment cbt. First it is necessary to have a clear understanding of the underlying genetic mechanisms is needed and an understanding of what is a reliable predictor of treatment response. In addition, ethical concerns like privacy and the ethical use of personal genetic information, must be considered carefully. In the long-term the use of pharmacogenetics could offer a chance to lessen the stigma associated with mental health care and improve the outcomes of those suffering with depression. But, like any other psychiatric holistic treatment for depression, careful consideration and planning is essential. For now, it is ideal to offer patients a variety of medications for depression that are effective and urge them to speak openly with their doctor.
