Personalized Depression Treatment
For a lot of people suffering from treating depression, traditional therapy and medication isn't effective. A customized treatment could be the answer.
Cue is an intervention platform that transforms passively acquired sensor data from smartphones into personalised micro-interventions that improve mental health. We parsed the best-fit personalized ML models for each subject using Shapley values to identify their predictors of feature and reveal distinct features that deterministically change mood over time.
Predictors of Mood
Depression is among the world's leading causes of mental illness.1 However, only half of people suffering from the condition receive treatment1. To improve outcomes, healthcare professionals must be able to recognize and treat patients who are the most likely to respond to certain treatments.
Personalized 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 working on new ways to predict which patients will benefit from which treatments. Two grants worth more than $10 million will be used to identify biological and behavioral predictors of response.
The majority of research on predictors for depression treatment effectiveness has centered on the sociodemographic and clinical aspects. These include factors that affect the demographics like age, sex and education, clinical characteristics including symptom severity and comorbidities, and biological markers such as neuroimaging and genetic variation.
While many of these variables can be predicted by the information in medical records, very few studies have used longitudinal data to explore predictors of mood in individuals. They have not taken into account the fact that mood varies significantly between individuals. Therefore, it is essential to create methods that allow the identification of the individual differences in mood predictors and the effects of treatment.
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 can then develop algorithms to detect patterns of behaviour and emotions that are unique to each individual.
The team also devised a machine-learning algorithm that can identify dynamic predictors of each person's depression mood. The algorithm combines these individual differences into a unique "digital phenotype" for each participant.
This digital phenotype has been correlated with CAT DI scores that are a psychometrically validated symptoms severity scale. The correlation was low, however (Pearson r = 0,08; BH adjusted P-value 3.55 x 10 03) and varied greatly between individuals.
Predictors of Symptoms
Depression is the most common reason for disability across the world1, however, it is often not properly diagnosed and treated. In addition the absence of effective treatments and stigma associated with depression disorders hinder many from seeking treatment.
To assist in individualized treatment, it is important to identify the factors that predict symptoms. However, the methods used to predict symptoms are based on the clinical interview, which has poor reliability and only detects a small 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 phenotypes collected from smartphone sensors with a valid mental health tracker online (the Computerized Adaptive Testing Depression Inventory CAT-DI). Digital phenotypes can provide continuous, high-resolution measurements. They also capture a wide range of distinct behaviors and patterns that are difficult to capture through interviews.
The study involved University of California Los Angeles students with mild to severe depression symptoms who were enrolled in the Screening and non drug treatment for anxiety and depression for Anxiety and Depression program29, which was developed as part of the UCLA Depression Grand Challenge. Participants were referred to online support or clinical care depending on the severity of their depression. Those with a CAT-DI score of 35 65 were allocated online support with the help of a peer coach. those with a score of 75 patients were referred for psychotherapy in person.
At baseline, participants provided a series of questions about their personal demographics and psychosocial characteristics. 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, as well as the frequency with which they consumed alcohol. Participants also scored their level of depression severity on a 0-100 scale using the CAT-DI. CAT-DI assessments were conducted every other week for participants who received online support and weekly for those receiving in-person treatment.
Predictors of the Reaction to Treatment
Personalized depression treatment is currently a top research topic, and many studies aim to identify predictors that enable clinicians to determine the most effective medications for each patient. Pharmacogenetics, for instance, uncovers genetic variations that affect how the body's metabolism reacts to drugs. This allows doctors to select drugs that are likely to work best for each patient, while minimizing the time and effort in trials and errors, while avoiding side effects that might otherwise hinder progress.
Another promising approach is to build predictive models that incorporate information from clinical studies and neural imaging data. These models can be used to identify the variables that are most predictive of a particular outcome, like whether a medication can help with symptoms or mood. These models can be used to predict the response of a patient to a treatment, which will help doctors to maximize the effectiveness of their treatment.
A new generation of machines employs machine learning techniques like algorithms for classification and supervised learning, regularized logistic regression and tree-based techniques to combine the effects from multiple variables and improve predictive accuracy. These models have been proven to be effective in predicting 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 the future of clinical practice.
Research into depression's underlying mechanisms continues, in addition to predictive models based on ML. Recent research suggests that the disorder is linked with neurodegeneration in particular circuits. This theory suggests that individualized depression treatment will be built around targeted therapies that target these circuits in order to restore normal functioning.
Internet-based-based therapies can be an effective method to accomplish this. They can provide an individualized and tailored experience for patients. One study found that an internet-based program helped improve symptoms and improved quality of life for MDD patients. In addition, a controlled randomized study of a personalised approach to depression treatment showed sustained improvement and reduced adverse effects in a large percentage of participants.
Predictors of adverse effects
A major obstacle in individualized depression treatment involves identifying and predicting which antidepressant medications will have the least amount of side effects or none at all. Many patients have a trial-and error method, involving several medications prescribed until they find one that is effective and tolerable. Pharmacogenetics offers a new and exciting method of selecting antidepressant medications that is more effective and precise.
There are a variety of variables that can be used to determine the antidepressant to be prescribed, including gene variations, patient phenotypes such as gender or ethnicity and comorbidities. However, identifying the most reliable and accurate predictors for a particular treatment is likely to require controlled, randomized trials with considerably larger samples than those that are typically part of clinical trials. This is because the identifying of interactions or moderators could be more difficult in trials that focus on a single instance of treatment per patient, rather than multiple episodes of treatment over a period of time.
In addition the prediction of a patient's response will likely require information on the severity of symptoms, comorbidities and the patient's own perception of effectiveness and tolerability. Presently, only a handful of easily identifiable sociodemographic and clinical variables appear to be reliably associated with response to MDD factors, including age, gender race/ethnicity, SES BMI, the presence of alexithymia, and the severity of depressive symptoms.
The application of pharmacogenetics to depression treatment is still in its beginning stages, and many challenges remain. First is a thorough understanding of the genetic mechanisms is needed, as is an understanding 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, in the long run reduce stigma associated with treatments for mental illness and improve the outcomes of treatment. But, like any other psychiatric treatment, careful consideration and planning is required. At present, the most effective option is to offer patients a variety of effective hormonal depression treatment medication options and encourage them to talk with their physicians about their experiences and concerns.
