Abstract

A system for evaluating mental health of patients includes a memory and a control system. The memory contains executable code storing instructions for performing a method. The control system is coupled to the memory and includes one or more processors. The control system is configured to execute the machine executable code to cause the control system to perform the method: A selection of answers associated with a patient is received. The selection of answers corresponds to each question in a series of questions from mental health questionnaires. Unprocessed MRI data are received. The unprocessed MRI data correspond to a set of MRI images of a biological structure associated with the patient. The unprocessed MRI data is processed to output a set of MRI features. Using a machine learning model, the selection of answers and the set of MRI features are processed to output a mental health indication of the patient.

Claims (60)

1. A system for evaluating a patient for mental health issues, the system comprising:

a user interface;

a control system coupled to the memory comprising one or more processors, the control system configured to execute the machine executable code to cause the control system to:

receive, from the user interface, a selection of answers from a patient, the selection of answers corresponding to each question in a series of questions from mental health questionnaires;

receive, unprocessed MM data associated with the patient; and

process, using a machine learning model, the selection of answers and the unprocessed MRI data to output a mental health indication of the patient,

wherein the machine learning model was generated by:

receiving training data corresponding to a plurality of individuals, the training data comprising:

MRI data; and

a selection of answers to the series of questions;

determining a plurality of features from the training data;

extracting importance measures for each of the plurality of features;

generating a plurality of subset machine learning models based on the extracted importance measures for the plurality of features; and

selecting at least one of the subset machine learning models as the machine learning model.

2. The system of claim 1 , wherein the unprocessed MM data corresponds to MRI data for a brain of the patient, wherein the training data is labeled training data corresponding to the plurality of individuals, the labeled training data indicating whether each of the plurality of individuals has one or more mental health disorders.

3. The system of claim 1 , wherein the unprocessed MRI data comprises at least one of: functional MM data, resting-state functional MM data, structural MRI data, and any combination thereof.

4. The system of claim 1 , wherein the control system is further configured to preprocess the unprocessed MRI data to identify a plurality of MRI features, wherein the machine learning model was further generated by training an initial machine learning model in a supervised manner using the plurality of features, wherein the extracting the importance measures for each of the plurality of features is based on the training of the initial machine learning model.

5. The system of claim 1 , wherein the machine learning model is at least one of: a generalized linear model, a regression model, a logistical regression model, a supervised regression method, random forest model, LASSO model, a supervised machine-learning model, and an elastic net model.

6. The system of claim 1 , wherein the selecting at least one of the subset machine learning models as the machine learning model includes evaluating a classification performance of the generated plurality of subset machine learning models.

7. The system of claim 1 , wherein the mental health indication is categorical, wherein the mental health indication comprises a determination that the processed selection of answers and the processed MM data includes indications of at least one of: a neuropsychiatric disorder, schizophrenia, a bi-polar disorder, and any combination thereof.

8. The system of claim 1 , wherein outputting the mental health indication further comprises determining that the processed selection of answers and the processed MRI data identifies features corresponding to a mental disorder.

9. A system for evaluating mental health of patients, the system comprising:

a memory containing machine readable medium comprising machine executable code having stored thereon instructions for performing a method; and

a control system coupled to the memory comprising one or more processors, the control system configured to execute the machine executable code to cause the control system to:

receive a selection of answers associated with a patient, the selection of answers corresponding to each question in a series of questions from mental health questionnaires;

receive, unprocessed MRI data associated with the patient;

and process, using a machine learning model, the selection of answers, and the set of MRI features, to output a mental health indication of the patient,

wherein the machine learning model was generated by:

receiving labeled training data corresponding to a plurality of individuals indicating whether each of the plurality of individuals has one or more mental health disorders, the labeled training data comprising:

MRI data; and

a selection of answers to the series of questions;

determining a plurality of features from the labeled training data;

training an initial machine learning model in a supervised manner, based on the plurality of features;

extracting importance measures for each of the plurality of features, based on the training of the initial machine learning model; and

generating the machine learning model based on the extracted importance measures for the plurality of features.

10. The system of claim 9 , wherein the unprocessed MM data corresponds to MM data for a brain of the patient.

11. The system of claim 9 , wherein the unprocessed MRI data comprises at least one of: functional MM data, resting-state functional MM data, structural MRI data, and any combination thereof.

12. The system of claim 9 , wherein the control system is further configured to preprocess the unprocessed MM data to identify a plurality of MRI features.

14. The system of claim 9 , the mental health indication comprises a determination that the processed selection of answers and the processed MRI data includes indications of at least one of: a neuropsychiatric disorder, schizophrenia, a bi-polar disorder, and any combination thereof.

15. The system of claim 9 , wherein outputting the mental health indication further comprises determining that the processed selection of answers and the processed MRI data identifies features corresponding to a mental disorder.

16. A computer-implemented method, comprising:

displaying a series of questions on a display device, the series of questions being from mental health questionnaires comprising text and answers for each question;

receive, from the user interface, a selection of answers from a patient, the selection of answers corresponding to the series of questions;

receive, unprocessed MM data associated with the patient; and

process, using a machine learning model, the selection of answers and the unprocessed MRI data to output a mental health indication of the patient,
