Personalized Depression Treatment

Traditional treatment and medications do not work for many people suffering from depression. A customized treatment could be the answer.

Cue is an intervention platform for digital devices that converts passively collected sensor data from smartphones into customized micro-interventions to improve mental health. We looked at the best-fitting personal ML models to each person using Shapley values to determine their feature predictors. This revealed distinct features that changed mood in a predictable manner over time.

Predictors of Mood

Depression is a leading cause of mental illness in the world.1 Yet, only half of those affected receive treatment. To improve outcomes, healthcare professionals must be able to recognize and treat patients who are the most likely to respond to specific treatments.

A customized depression treatment is one method of doing this. Utilizing sensors for mobile phones as well as 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 the treatments they receive. Two grants worth more than $10 million will be used to discover the biological and behavioral indicators of response.

The majority of research on factors that predict depression treatment effectiveness has been focused on the sociodemographic and clinical aspects. These include demographics such as age, gender and education and clinical characteristics like severity of symptom and comorbidities, as well as biological markers.

While many of these aspects can be predicted by the information available in medical records, very few studies have employed longitudinal data to determine the causes of mood among individuals. Few also take into account the fact that mood varies significantly between individuals. It is therefore important to develop methods that permit the determination and quantification of the individual differences between mood predictors treatments, mood predictors, etc.

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. The team is able to develop algorithms to recognize patterns of behavior and emotions that are unique to each person.

The team also devised a machine learning algorithm to create dynamic predictors for each person's depression mood. The algorithm blends these individual variations into a distinct "digital phenotype" for each participant.

This digital phenotype has been associated with CAT DI scores which is a psychometrically validated symptom severity scale. The correlation was weak, however (Pearson r = 0,08, BH adjusted P-value 3.55 x 10 03) and varied greatly between individuals.

Predictors of symptoms

Depression is one of the world's leading causes of disability1 yet it is often untreated and not diagnosed. depression treatment during pregnancy disorders are rarely treated due to the stigma associated with them and the lack of effective interventions.

To assist in individualized treatment, it is important to identify the factors that predict symptoms. However, current prediction methods depend on the clinical interview which has poor reliability and only detects a small number of symptoms related to depression.2

Machine learning can enhance the accuracy of diagnosis and treatment for depression by combining continuous digital behavioral phenotypes gathered from smartphones along with a verified mental health tracker online (the Computerized Adaptive Testing Depression Inventory CAT-DI). Digital phenotypes permit continuous, high-resolution measurements as well as capture a variety of distinct behaviors and patterns that are difficult to capture through interviews.

The study involved University of California Los Angeles (UCLA) students with moderate to severe depressive symptoms. who were enrolled in the Screening and Treatment for Anxiety and deep depression treatment (STAND) program29 that was created under the UCLA Depression Grand Challenge. Participants were routed to online support or in-person clinical care depending on their depression and anxiety treatment near me severity. Those with a CAT-DI score of 35 or 65 were given online support with an instructor and those with a score 75 were routed to in-person clinical care for psychotherapy.

At the beginning, participants answered an array of questions regarding their personal demographics and psychosocial features. The questions asked included age, sex and education as well as marital status, financial status and whether they were divorced or not, current suicidal ideas, intent or attempts, and how often they drank. The CAT-DI was used to assess the severity of depression-related symptoms on a scale ranging from 0-100. The CAT DI assessment was performed every two weeks for those who received online support, and weekly for those who received in-person care.

Predictors of Treatment Response

Research is focusing on personalized treatment for depression. Many studies are aimed at finding predictors that can help clinicians identify the most effective medications to treat each patient. Pharmacogenetics, in particular, is a method of identifying genetic variations that affect how the human body metabolizes drugs. This allows doctors select medications that will likely work best for each patient, reducing the time and effort needed for trial-and-error treatments and avoiding any side consequences.

Another approach that is promising is to build prediction models using multiple data sources, combining clinical information and neural imaging data. These models can be used to determine which variables are the most likely to predict a specific outcome, like whether a medication will improve symptoms or mood. These models can also be used to predict a patient's response to a treatment they are currently receiving which allows doctors to maximize the effectiveness of current therapy.

A new era of research utilizes machine learning techniques, such as supervised learning and classification algorithms (like regularized logistic regression or tree-based methods) to combine the effects of many variables and improve the accuracy of predictive. These models have been demonstrated to be effective in predicting the outcome of non pharmacological treatment for depression, such as response to antidepressants. These methods are becoming popular in psychiatry, and it is expected that they will become the standard for the future of clinical practice.

Research into depression's underlying mechanisms continues, as well as predictive models based on ML. Recent findings suggest that the disorder is connected with neural dysfunctions that affect specific circuits. This theory suggests that an individualized treatment for depression will be based upon targeted therapies that restore normal functioning to these circuits.

Internet-based-based therapies can be an option to accomplish this. They can offer an individualized and tailored experience for patients. One study found that an internet-based program improved symptoms and improved quality of life for MDD patients. A controlled, randomized study of a customized treatment for depression revealed that a significant percentage of participants experienced sustained improvement and fewer side effects.

Predictors of Side Effects

In the treatment of depression the biggest challenge is predicting and identifying which antidepressant medications will have no or minimal side effects. Many patients are prescribed a variety medications before settling on a treatment that is effective and tolerated. Pharmacogenetics provides an exciting new avenue for a more efficient and targeted method of selecting antidepressant therapies.

There are several variables that can be used to determine which antidepressant should be prescribed, including gene variations, phenotypes of the patient like gender or ethnicity, and comorbidities. However finding the most reliable and valid predictors for a particular treatment will probably require controlled, randomized trials with significantly larger numbers of participants than those normally enrolled in clinical trials. This is because it may be more difficult to determine interactions or moderators 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 also likely need to incorporate information regarding comorbidities and symptom profiles, as well as the patient's previous experience of its tolerability and effectiveness. There are currently only a few easily assessable sociodemographic variables and clinical variables are consistently associated with response to MDD. These include gender, age, race/ethnicity as well as BMI, SES and the presence of alexithymia.

Many challenges remain when it comes to the use of pharmacogenetics for depression and anxiety treatment near Me treatment. First, it is important to have a clear understanding and definition of the genetic mechanisms that underlie depression, as well as an accurate definition of a reliable predictor of treatment response. In addition, ethical concerns such as privacy and the ethical use of personal genetic information, must be considered carefully. In the long-term pharmacogenetics can offer a chance to lessen the stigma that surrounds mental health care and improve the outcomes of those suffering with depression. But, like any approach to psychiatry careful consideration and application is required. At present, the most effective method is to provide patients with an array of effective depression medications and encourage them to talk openly with their doctors about their experiences and concerns.
