Personalized Depression Treatment
Traditional therapy and medication don't work for a majority of patients suffering from depression. The individual approach to treatment could be the answer.
Cue is an intervention platform that transforms passively acquired sensor data from smartphones into customized micro-interventions to improve mental health. We examined the most effective-fitting personalized ML models to each subject using Shapley values, in order to understand their characteristic predictors. The results revealed distinct characteristics that changed mood in a predictable manner over time.
Predictors of Mood
Depression is a major cause of mental illness in the world.1 Yet, only half of those suffering from the condition receive treatment. To improve the outcomes, doctors must be able identify and treat patients most likely to respond to specific treatments.
The treatment of depression can be personalized to help. By using mobile phone sensors 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. With two grants totaling more than $10 million, they will employ these technologies to identify the biological and behavioral factors that determine responses to antidepressant medications as well as psychotherapy.
The majority of research to so far has focused on clinical and sociodemographic characteristics. These include demographics such as age, gender, and education, and clinical characteristics like severity of symptom and comorbidities, as well as biological markers.
Very few studies have used longitudinal data in order to predict mood of individuals. They have not taken into account the fact that moods vary significantly between individuals. It is therefore important to develop methods which permit the determination and quantification of the individual differences in mood predictors and treatment effects, for instance.
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 different patterns of behavior and emotion that are different between people.
In addition to these modalities, the team developed a machine-learning algorithm to model the dynamic variables that influence each person's mood. The algorithm blends these individual characteristics into a distinctive "digital phenotype" for each participant.
This digital phenotype was correlated with CAT DI scores that are a psychometrically validated symptoms severity scale. However, the correlation was weak (Pearson's r = 0.08, adjusted BH-adjusted P-value of 3.55 x 10-03) and varied widely among individuals.
Predictors of Symptoms
Depression is the leading cause of disability around the world1, but it is often untreated and misdiagnosed. Depression disorders are usually not treated due to the stigma attached to them and the lack of effective treatments.
To aid in the development of a personalized treatment plan, identifying predictors of symptoms is important. However, current prediction methods are based on the clinical interview, which has poor reliability and only detects a tiny variety of characteristics that are associated with depression.2
Machine learning can enhance the accuracy of the diagnosis and treatment of depression by combining continuous digital behavior phenotypes gathered from smartphones with a valid mental health tracker online (the Computerized Adaptive Testing Depression Inventory CAT-DI). These digital phenotypes capture a large number of distinct actions and behaviors that are difficult to record through interviews and permit continuous and high-resolution measurements.
The study involved University of California Los Angeles (UCLA) students experiencing moderate to severe depressive symptoms. who were enrolled in the Screening and Treatment for Anxiety and Depression (STAND) program29 that was created under the UCLA Depression Grand Challenge. Participants were directed to online support or clinical care according to the severity of their depression. Patients who scored high on the CAT-DI scale of 35 or 65 were allocated online support with the help of a peer coach. those with a score of 75 patients were referred for in-person psychotherapy.
Participants were asked a set of questions at the beginning of the study about their demographics and psychosocial traits. These included sex, age, education, work, and financial status; if they were divorced, partnered, or single; current suicidal ideas, intent or attempts; as well as the frequency at that they consumed alcohol. Participants also rated their degree of depression severity on a scale of 0-100 using the CAT-DI. CAT-DI assessments were conducted every other week for participants who received online support and once a week for those receiving in-person care.
Predictors of Treatment Reaction
Personalized depression treatment is currently a major research area and many studies aim at identifying predictors that will enable clinicians to determine the most effective medication for each individual. Particularly, pharmacogenetics is able to identify genetic variations that affect how the body metabolizes antidepressants. This allows doctors to select drugs that are likely to work best for each patient, reducing the time and effort in trial-and-error procedures and avoiding side effects that might otherwise slow the progress of the patient.
Another option is to build prediction models combining clinical data and neural imaging data. These models can then be used to identify the best combination of variables that is predictors of a specific outcome, like whether or not a drug will improve mood and symptoms. These models can be used to determine the patient's response to a treatment, allowing doctors to maximize the effectiveness of their treatment.
A new generation of studies employs machine learning techniques like supervised learning and classification algorithms (like regularized logistic regression or tree-based techniques) to combine the effects of multiple variables and improve the accuracy of predictive. These models have been shown to be effective in predicting outcomes 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 standard for the future of clinical practice.
Research into depression's underlying mechanisms continues, in addition to ML-based predictive models. Recent findings suggest that depression and anxiety treatment near me is related to the dysfunctions of specific neural networks. This theory suggests that an individualized treatment for depression will depend on targeted therapies that restore normal functioning to these circuits.
One way to do this is to use internet-based interventions that can provide a more individualized and personalized experience for patients. For example, one study found that a program on the internet was more effective than standard care in reducing symptoms and ensuring an improved quality of life for patients suffering from MDD. A controlled study that was randomized to a personalized treatment for depression found that a significant percentage of patients experienced sustained improvement and had fewer adverse consequences.
Predictors of side effects
In the treatment of Treating depression without antidepressants a major challenge is predicting and determining which antidepressant medication will have very little or no negative side effects. Many patients are prescribed various medications before settling on a treatment that is safe and effective. Pharmacogenetics offers a fascinating new avenue for a more efficient and specific approach to selecting antidepressant treatments.
Several predictors may be used to determine which antidepressant is best to prescribe, including genetic variants, phenotypes of patients (e.g. gender, sex or ethnicity) and comorbidities. However, identifying the most reliable and valid predictive factors for a specific treatment is likely to require controlled, randomized trials with considerably larger samples than those that are typically part of clinical trials. This is because it could be more difficult to determine the effects of moderators or interactions in trials that only include one episode per participant instead of multiple episodes over time.
In addition to that, predicting a patient's reaction will likely require information on the comorbidities, symptoms profiles and the patient's personal perception of effectiveness and tolerability. At present, only a handful of easily identifiable sociodemographic variables and clinical variables appear to be reliably related to response to MDD. These include gender, age, race/ethnicity, BMI, SES and the presence of alexithymia.
There are many challenges to overcome in the use of pharmacogenetics in the treatment of situational depression treatment. First it is necessary to have a clear understanding of the genetic mechanisms is essential, as is an understanding of what is depression treatment is a reliable indicator of treatment response. In addition, ethical concerns such as privacy and the ethical use of personal genetic information must be considered carefully. Pharmacogenetics can be able to, over the long term, reduce stigma surrounding mental health treatment and improve the quality of treatment. As with all psychiatric approaches it is essential to take your time and carefully implement the plan. At present, it's ideal to offer patients an array of depression medications that work and encourage them to talk openly with their doctors.
