Personalized Depression Treatment
Traditional therapy and medication don't work for a majority of people suffering from depression. A customized treatment could be the answer.
Cue is an intervention platform that converts sensor data collected from smartphones into personalised micro-interventions to improve mental health. We analysed the best-fit personalized ML models for each subject using Shapley values to understand their feature predictors and reveal distinct features that are able to change mood over time.
Predictors of Mood
Depression is a leading cause of mental illness across the world.1 Yet only half of those suffering from the condition receive treatment. In order to improve outcomes, clinicians need to be able to recognize and treat patients who have the highest chance of responding to certain treatments.
The treatment of depression can be personalized to help. Researchers at the University of Illinois Chicago are developing new methods for predicting which patients will benefit the most from specific treatments. They use sensors on mobile phones and a voice assistant incorporating artificial intelligence, and other digital tools. Two grants totaling more than $10 million will be used to determine biological and behavior factors that predict response.
The majority of research on predictors for depression treatment effectiveness has focused on the sociodemographic and clinical aspects. These include demographic factors such as age, sex and education, clinical depression treatments characteristics such as symptoms severity and comorbidities and biological indicators such as neuroimaging and genetic variation.
While many of these factors can be predicted from the information in medical records, only a few studies have used longitudinal data to study the causes of mood among individuals. Few also take into account the fact that mood varies significantly between individuals. Therefore, it is critical to develop methods that permit the identification of different mood predictors for each person 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. The team is able to develop algorithms to identify patterns of behaviour and emotions that are unique to each individual.
In addition to these modalities, the team created a machine learning algorithm that models the dynamic predictors of each person's depressed mood. The algorithm combines the individual differences to create an individual "digital genotype" for each participant.
This digital phenotype was correlated with CAT-DI scores, a psychometrically validated symptom severity scale. The correlation was weak however (Pearson r = 0,08, P-value adjusted by BH 3.55 x 10 03) and varied widely among individuals.
Predictors of Symptoms
Depression is the most common cause of disability around the world, but it is often not properly diagnosed and treated. Depressive disorders are often not treated because of the stigma associated with them, as well as the lack of effective treatments.
To facilitate personalized treatment, identifying factors that predict the severity of symptoms is crucial. However, current prediction methods depend on the clinical interview which is unreliable and only detects a tiny variety of characteristics that are associated with depression.2
Machine learning can be used to blend continuous digital behavioral phenotypes that are captured by sensors on smartphones and a validated online mental depression treatment health tracker (the Computerized Adaptive Testing Depression Inventory CAT-DI) with other predictors of severity of symptoms could improve the accuracy of diagnosis and the effectiveness of treatment for depression. Digital phenotypes permit continuous, high-resolution measurements and capture a wide range of unique behaviors and activity patterns that are difficult to document through interviews.
The study enrolled University of California Los Angeles (UCLA) students who were suffering from moderate to severe depressive symptoms. who were enrolled in the Screening and Treatment for Anxiety and Depression (STAND) program29 developed under the UCLA Depression Grand Challenge. Participants were sent online for support or clinical care depending on the degree of their depression. Participants who scored a high on the CAT-DI of 35 or 65 were allocated online support via the help of a peer coach. those who scored 75 patients were referred to in-person clinics for psychotherapy.
At the beginning, participants answered a series of questions about their personal characteristics and psychosocial traits. The questions asked included age, sex, and education, marital status, financial status and whether they were divorced or not, the frequency of suicidal ideas, intent or attempts, as well as the frequency with which they consumed alcohol. Participants also scored their level of depression symptom severity on a 0-100 scale using the CAT-DI. CAT-DI assessments were conducted each other week for participants that received online support, and once a week for those receiving in-person care.
Predictors of the Reaction to Treatment
Research is focusing on personalized treatment for depression. Many studies are aimed at identifying predictors, which will help clinicians identify the most effective drugs to treat each patient. Pharmacogenetics, for instance, identifies genetic variations that determine the way that our bodies process drugs. This allows doctors to select the medications that are most likely to work best for each patient, reducing the time and effort in trials and errors, while eliminating any side effects that could otherwise slow advancement.
Another option is to build prediction models that combine the clinical data with neural imaging data. These models can be used to determine the most effective combination of variables predictive of a particular outcome, such as whether or not a particular medication is likely to improve the mood and symptoms. These models can also be used to predict the response of a patient to what treatment is there for depression that is already in place and help doctors maximize the effectiveness of the treatment currently being administered.
A new type of research uses machine learning methods such as supervised learning and classification algorithms (like regularized logistic regression or tree-based techniques) to combine the effects of many variables and improve the accuracy of predictive. These models have proven to be effective in forecasting treatment outcomes, such as the response to antidepressants. These models are getting more popular in psychiatry, and it is likely that they will become the norm for future clinical practice.
In addition to ML-based prediction models The study of the underlying mechanisms of depression is continuing. Recent findings suggest that morning depression treatment is connected to dysfunctions in specific neural networks. This suggests that an individualized treatment for depression will be based on targeted therapies that restore normal function to these circuits.
Internet-based interventions are an effective method to achieve this. They can offer an individualized and tailored experience for patients. A study showed that a web-based program improved symptoms and improved quality life for MDD patients. A randomized controlled study of an individualized treatment for depression found that a significant number of patients experienced sustained improvement and had fewer adverse effects.
Predictors of side effects
In the treatment of depression a major challenge is predicting and determining which antidepressant medication will have no or minimal side effects. Many patients are prescribed a variety of medications before finding a medication that is safe and effective. Pharmacogenetics offers a new and exciting way to select antidepressant medications that is more effective and specific.
Many predictors can be used to determine which antidepressant is best Medicine To Treat Anxiety And Depression prescribe, including gene variants, phenotypes of patients (e.g. sexual orientation, gender or ethnicity) and the presence of comorbidities. To identify the most reliable and reliable predictors of a specific treatment, randomized controlled trials with larger sample sizes will be required. This is because it could be more difficult to determine the effects of moderators or interactions in trials that comprise only one episode per participant rather than multiple episodes over a period of time.
Furthermore to that, predicting a patient's reaction will likely require information about the severity of symptoms, comorbidities and the patient's own perception of effectiveness and tolerability. At present, only a handful of easily measurable sociodemographic variables as well as clinical variables seem to be reliable in predicting the response to MDD. These include age, gender and race/ethnicity, BMI, SES and the presence of alexithymia.
The application of pharmacogenetics to depression treatment is still in its infancy, and many challenges remain. First, it is important to have a clear understanding and definition of the genetic factors that cause depression, and a clear definition of an accurate predictor of treatment response. Additionally, ethical issues, such as privacy and the ethical use of personal genetic information should be considered with care. In the long term pharmacogenetics can be a way to lessen the stigma associated with mental health treatment and improve the treatment outcomes for patients with depression. As with any psychiatric approach it is crucial 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 physicians.
