Systems and methods for assessing
schizophrenia, for example severity of
schizophrenia, may use a trained
machine learning model. An audio recording of a patient may be processed to determine acoustic data related to the audio recording. The
system may determine, for example using the trained
machine learning model, a digital biomarker. The digital biomarker may correspond to
schizophrenia severity of the patient using the acoustic data. The digital biomarker may correspond to a positive and negative syndrome scale (PANSS)
score. For example, the digital biomarker may include an indication of one or more symptoms and / or the severity of schizophrenia.
