In December 2020, researchers led by Michael Birnbaum at the Feinstein Institutes for Medical Research demonstrated that an AI algorithm could predict psychiatric diagnoses up to 18 months before official diagnosis by analyzing Facebook messages and photos from 223 volunteers. The AI identified linguistic and visual markers associated with mood disorders and schizophrenia spectrum disorders, achieving accuracy comparable to traditional screening tools like the PHQ-9 survey. This approach suggests the potential for earlier detection and treatment of mental illnesses, though experts emphasize the importance of ethical considerations and privacy protections in such applications
