Personalized Depression Treatment

Traditional treatment and medications do not work for many patients suffering from bipolar depression treatment. Personalized treatment may be the solution.

Cue is an intervention platform for digital devices that transforms passively acquired smartphone sensor data into personalized micro-interventions to improve mental health. We analyzed the best treatment for severe depression-fitting personalized ML models for each individual, using Shapley values to determine their characteristic predictors. This revealed distinct features that changed mood in a predictable manner 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, clinicians need to be able to recognize and treat patients who have the highest likelihood of responding to specific treatments.

A customized depression treatment is one way to do this. Utilizing 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 determine which patients will benefit from which treatments. Two grants worth more than $10 million will be used to determine biological and behavioral factors that predict response.

The majority of research to date has focused on sociodemographic and clinical characteristics. These include demographic variables like age, sex and education, clinical characteristics including symptom severity and comorbidities, and biological indicators such as 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 determine the factors that influence mood in people. A few studies also take into account the fact that mood can differ significantly between individuals. Therefore, it is critical to create methods that allow the recognition of individual differences in mood predictors and treatment 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 create algorithms that can detect distinct patterns of behavior and emotions that vary between individuals.

In addition to these modalities, the team also developed a machine-learning algorithm to model the changing variables that influence each person's mood. The algorithm combines these personal differences into a unique "digital phenotype" for each participant.

This digital phenotype has been associated with CAT DI scores which is a psychometrically validated symptom severity scale. However the correlation was not strong (Pearson's r = 0.08, the BH-adjusted p-value was 3.55 1003) and varied widely among individuals.

Predictors of symptoms

dementia depression treatment is the most common cause of disability in the world, but it is often untreated and misdiagnosed. Depressive disorders are often not treated due to the stigma that surrounds them and the lack of effective interventions.

alternative ways to treat depression aid in the development of a personalized treatment, it is crucial to identify predictors of symptoms. However, the current methods for predicting symptoms rely on clinical interview, which is unreliable and only detects a limited number of symptoms associated with depression.2

Machine learning can improve the accuracy of diagnosis and treatment for 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 can be used to are able to capture a variety of unique actions and behaviors that are difficult to capture through interviews and permit high-resolution, continuous measurements.

The study enrolled University of California Los Angeles (UCLA) students experiencing moderate to severe depressive symptoms. enrolled in the Screening and Treatment for Anxiety and Depression (STAND) program29 developed under the UCLA Depression Grand Challenge. Participants were routed to online support or in-person clinical care in accordance with their severity of depression. Participants who scored a high on the CAT-DI scale of 35 65 were assigned to online support with 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 regarding their demographics and psychosocial characteristics. These included sex, age and education, as well as work and financial situation; whether they were partnered, divorced or single; the frequency of suicidal ideas, intent or attempts; as well as the frequency at which they drank alcohol. The CAT-DI was used for assessing the severity of depression symptoms on a scale from 0-100. The CAT-DI assessment was carried out every two weeks for participants who received online support and weekly for those who received in-person support.

Predictors of the Reaction to Treatment

Personalized depression treatment is currently a top research topic and a lot of studies are aimed at identifying predictors that help clinicians determine the most effective medication for each person. Particularly, pharmacogenetics is able to identify genetic variants that influence the way that the body processes antidepressants. This lets doctors select the medication that are most likely to work for each patient, while minimizing time and effort spent on trial-and-error treatments and eliminating any adverse consequences.

Another promising method is to construct models for prediction using multiple data sources, including clinical information and neural imaging data. These models can be used to determine the variables that are most predictive of a specific outcome, like whether a drug will help with symptoms or mood. These models can be used to determine the patient's response to a Ketamine treatment for depression, allowing doctors to maximize the effectiveness.

A new era of research employs machine learning techniques, such as supervised learning and classification algorithms (like regularized logistic regression or tree-based methods) to combine the effects of multiple variables and improve the accuracy of predictive. These models have proven to be useful in the prediction of treatment outcomes like the response to antidepressants. These approaches are gaining popularity in psychiatry and it is expected that they will become the norm for future clinical practice.

In addition to the ML-based prediction models research into the mechanisms behind depression is continuing. Recent findings suggest that the disorder is associated with neurodegeneration in particular circuits. This suggests that individual depression treatment will be built around targeted treatments that target these circuits to restore normal function.

Internet-based interventions are an effective method to achieve this. They can offer a more tailored and individualized experience for patients. A study showed that an internet-based program improved symptoms and led to a better quality life for MDD patients. A controlled, randomized study of a customized treatment for depression showed that a significant number of participants experienced sustained improvement and fewer side negative effects.

Predictors of side effects

A major challenge in personalized depression treatment is 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 a variety of medications prescribed until they find one that is effective and tolerable. Pharmacogenetics is an exciting new avenue for a more efficient and targeted approach to selecting antidepressant treatments.

A variety of predictors are available to determine which antidepressant to prescribe, such as gene variants, phenotypes of patients (e.g., sex or ethnicity) and comorbidities. However, identifying the most reliable and reliable predictors for a particular treatment will probably require randomized controlled trials of considerably larger samples than those normally enrolled in clinical trials. This is because the detection of interaction effects or moderators could be more difficult in trials that only consider a single episode of treatment per person instead of multiple episodes of treatment over time.

Additionally, the prediction of a patient's reaction to a specific medication will also likely require information about symptoms and comorbidities as well as the patient's prior subjective experience with tolerability and efficacy. Currently, only some easily assessable sociodemographic and clinical variables are believed to be reliable in predicting the response to MDD, such as gender, age race/ethnicity BMI, the presence of alexithymia, and the severity of depression symptoms.

The application of pharmacogenetics in treatment for depression is in its beginning stages, and many challenges remain. First is a thorough understanding of the underlying genetic mechanisms is required and an understanding of what is the best treatment for anxiety and depression is a reliable indicator of treatment response. Ethics, such as privacy, and the responsible use genetic information must also be considered. In the long term the use of pharmacogenetics could offer a chance to lessen the stigma that surrounds mental health care and improve treatment outcomes for those struggling with depression. Like any other psychiatric treatment it is essential to take your time and carefully implement the plan. In the moment, it's best to offer patients various depression medications that are effective and urge them to talk openly with their physicians.
