Personalized Depression Treatment

Traditional therapy and medication are not effective for a lot of patients suffering from depression. A customized treatment could be the solution.

Cue is an intervention platform that transforms sensors that are passively gathered from smartphones into personalised micro-interventions that improve mental health. We analyzed the most effective-fit personal ML models for each subject using Shapley values to identify their feature predictors and reveal distinct features that deterministically change mood over time.

Predictors of Mood

Depression is among the most prevalent causes of mental illness.1 However, only about half of those who have the condition receive treatment1. To improve outcomes, doctors must be able to recognize and treat patients who have the highest probability of responding to specific treatments.

The treatment for depression uk of depression can be personalized to help. Using sensors for mobile phones, an artificial intelligence voice assistant and other digital tools, researchers at the University of Illinois Chicago (UIC) are developing new methods to predict which patients will benefit from which treatments. Two grants totaling more than $10 million will be used to determine biological and behavior predictors of response.

The majority of research done to the present has been focused on sociodemographic and clinical characteristics. These include demographic factors such as age, gender and education, clinical characteristics including symptom severity and comorbidities, and biological markers like neuroimaging and genetic variation.

While many of these factors can be predicted from the data in medical records, few studies have utilized longitudinal data to explore the causes of mood among individuals. Many studies do not take into consideration the fact that moods vary significantly between individuals. Therefore, it is essential to create methods that allow the determination of 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 enables the team to develop algorithms that can detect various patterns of behavior and emotion that differ between individuals.

In addition to these modalities the team created a machine learning algorithm to model the changing 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, a psychometrically validated scale for assessing severity of symptom. However, the correlation was weak (Pearson's r = 0.08, BH-adjusted P-value of 3.55 x 10-03) and varied widely among individuals.

Predictors of symptoms

depression treatment brain stimulation is one of the world's leading causes of disability1 but is often untreated and not diagnosed. Depressive disorders are often not treated due to the stigma attached to them and the lack of effective interventions.

To facilitate personalized treatment to improve treatment, identifying the patterns that can predict symptoms is essential. However, the methods used to predict symptoms depend on the clinical interview which is unreliable and only detects a limited number of features that are associated with depression.2

Machine learning can increase the accuracy of diagnosis and treatment for depression by combining continuous, digital behavioral patterns gathered from sensors on smartphones with a valid mental health tracker online (the Computerized Adaptive Testing Depression Inventory CAT-DI). Digital phenotypes can provide continuous, high-resolution measurements as well as capture a wide range of unique behaviors and activity patterns that are difficult to document using interviews.

The study included University of California Los Angeles (UCLA) students experiencing mild to severe depression symptoms. participating in the Screening and Treatment for Anxiety and Depression (STAND) program29 that was created under the UCLA depression treatment plan Grand Challenge. Participants were referred to online support or clinical care depending on the severity of their depression. Participants who scored a high on the CAT DI of 35 or 65 were assigned online support with the help of a coach. Those with a score 75 were routed to in-person clinical care for psychotherapy.

Participants were asked a series questions at the beginning of the study concerning their demographics and psychosocial traits. These included age, sex education, work, and financial status; if they were divorced, married or single; their current suicidal ideation, intent or attempts; and the frequency with the frequency they consumed alcohol. The CAT-DI was used to assess the severity of depression-related symptoms on a scale from zero to 100. CAT-DI assessments were conducted every other week for the participants that received online support, and once a week for those receiving in-person care.

Predictors of the Reaction to Treatment

Personalized depression treatment is currently a major research area and a lot of studies are aimed at identifying predictors that will enable clinicians to determine the most effective medications for each person. Pharmacogenetics in particular is a method of identifying genetic variations that affect how the body's metabolism reacts to drugs. This allows doctors select medications that are likely to be the most effective for every patient, minimizing time and effort spent on trial-and error treatments and eliminating any adverse effects.

Another promising approach is building models of prediction using a variety of data sources, including data from clinical studies and neural imaging data. These models can then be used to determine the most effective combination of variables predictors of a specific outcome, like whether or not a particular medication will improve symptoms and mood. These models can also be used to predict a patient's response to treatment that is already in place, allowing doctors to maximize the effectiveness of their current therapy.

A new generation employs machine learning methods such as supervised and classification algorithms such as regularized logistic regression, and tree-based methods to integrate the effects of multiple variables and improve predictive accuracy. These models have shown to be effective in the prediction of natural treatment for anxiety and depression outcomes like the response to antidepressants. These models are getting more popular in psychiatry and it is expected that they will become the standard for the future of clinical practice.

Research into the underlying causes of depression continues, as do predictive models based on ML. Recent findings suggest that the disorder is linked with neural dysfunctions that affect specific circuits. This suggests that an individualized treatment for depression will depend on targeted therapies that restore normal functioning to these circuits.

One method of doing this is to use internet-based interventions which can offer an individualized and personalized experience for patients. One study found that an internet-based program improved symptoms and improved quality of life for MDD patients. Additionally, a randomized controlled trial of a personalized approach to treating depression showed steady improvement and decreased side effects in a significant number of participants.

Predictors of Side Effects

A major issue in personalizing depression treatment is predicting which antidepressant medications will have the least amount of side effects or none at all. Many patients have a trial-and error approach, using various medications prescribed until they find one that is safe and effective. Pharmacogenetics provides an exciting new avenue for a more efficient and targeted approach to choosing antidepressant medications.

Several predictors may be used to determine which antidepressant is best to prescribe, such as gene variations, phenotypes of patients (e.g. sexual orientation, gender or ethnicity) and co-morbidities. To identify the most reliable and valid predictors for a particular treatment, random controlled trials with larger samples will be required. This is due to the fact that the identification of interaction effects or moderators may be much more difficult in trials that consider a single episode of treatment per patient instead of multiple sessions of treatment over time.

Furthermore to that, predicting a patient's reaction will likely require information about the comorbidities, symptoms profiles and the patient's own experience of tolerability and effectiveness. Currently, only some easily assessable sociodemographic and clinical variables appear to be reliable in predicting response to MDD, such as gender, age race/ethnicity, SES BMI and the presence of alexithymia, and the severity of depressive symptoms.

Many challenges remain when it comes to the use of pharmacogenetics for depression treatment. First Line Treatment For Depression is a thorough understanding of the genetic mechanisms is essential, as is a clear definition of what is a reliable predictor of treatment response. Ethics such as privacy and the ethical use of genetic information must also be considered. Pharmacogenetics could be able to, over the long term help reduce stigma around mental health treatment and improve treatment outcomes. As with any psychiatric approach, it is important to carefully consider and implement the plan. The best course of action is to provide patients with an array of effective medications for depression and encourage them to talk openly with their doctors about their experiences and concerns.
