Patent number: 12277929Abstract: System and method for detecting cognitive decline in a subject using a classification system for detecting cognitive decline in the subject based on a speech sample. The classification system is trained using speech data corresponding to audio recordings of speech from normal and cognitive decline patients to generate an ensemble classifier comprising a plurality of component classifiers and an ensemble module. Each of the plurality of component classifiers is a machine-learning classifier configured to generate a component output identifying a sample data as corresponding to a normal patient or a cognitive patient. The machine-learning classifier is generated based on a subset of available features. The ensemble module receives component outputs from all of the component classifiers and generates an ensemble output identifying the sample data as corresponding to a normal or cognitive decline patient based on the component outputs.Type: GrantFiled: April 17, 2023Date of Patent: April 15, 2025Assignee: Janssen Pharmaceutica NVInventors: Srinivasan Vairavan, Vaibhav Narayan

Publication number: 20230301573Abstract: The invention provides methods of identifying schizophrenia patients at risk for relapse. The invention also provides methods of early detection of schizophrenic relapse. The disclosed methods use monitoring of a subset of symptoms and/or one or more biomarkers. The symptom severity can be assessed using the Positive and Negative Syndrome Scale (PANSS) parameters. The methods of the invention can be used to provide early intervention to decrease or prevent relapse in schizophrenia patients.Type: ApplicationFiled: May 9, 2023Publication date: September 28, 2023Applicant: JANSSEN PHARMACEUTICA NVInventors: Dai Wang, Srihari Gopal, Vaibhav Narayan, Adam Savitz, Susan Baker

Publication number: 20230245773Abstract: A system and computer-implemented method for detecting return of depression of a patient is provided. The system comprises a wearable device configured to detect movement of the patient and configured to generate actigraphy data corresponding to the movement of the patient and a computing device for retrieving actigraphy data from the device. The system and method obtain training data, including training actigraphy data, over a training period and train an anomaly detector using the training data. The system and method subsequently obtain test data from the patient, extract a plurality of features from the test data, and analyze the extracted data using the trained anomaly detector. A self-report test is used to determine whether an anomaly identified by the anomaly detector indicates that the patient is likely to experience return of depression.Type: ApplicationFiled: July 6, 2021Publication date: August 3, 2023Applicant: JANSSEN PHARMACEUTICA NVInventors: SRINIVASAN VAIRAVAN, VAIBHAV NARAYAN, RANDALL MORRISON
