Digital biomarker of dementia and depression

A computing device, comprising:

• a memory device to store computer-readable instructions thereon;
• and
• at least one processing device configured through execution of the computer-readable instructions to:
• identify a defined linguistic pattern in digital biomarker data of a user;
• prompt the user to perform a defined screening test based at least in part on identifying the defined linguistic pattern;
• monitor linguistic performance of the user while the user performs the defined screening test;
• and
• determine a diagnosis for the user based at least in part on the defined linguistic pattern, the linguistic performance, and a test result for the user from the defined screening test.

A computer-implemented method of diagnosing health conditions for users, the method comprising:

• identifying, by a computing device, a defined linguistic pattern in digital biomarker data of a user;
• implementing, by the computing device, a defined screening test to be performed by the user based at least in part on identifying the defined linguistic pattern;
• monitoring, by the computing device, linguistic performance of the user during the defined screening test;
• and
• determining, by the computing device, a diagnosis for the user based at least in part on the defined linguistic pattern, the linguistic performance, and a test result for the user from the defined screening test.
