Mental Health Applications of Generative AI and Large Language Modeling in the United States
Banerjee, S., Dunn, P., Conard, S., & Ali, A. International Journal of Environmental Research and Public Health
Background
Artificial intelligence (AI) has flourished in recent years. More specifically, generative AI has had broad applications in many disciplines. While mental illness is on the rise, AI has proven valuable in aiding the diagnosis and treatment of mental disorders. However, there is little to no research about precisely how much interest there is in AI technology.
Methods
The study performed a Google Trends search for 'AI and mental health' and compared relative search volume (RSV) indices of 'AI', 'AI and Depression', and 'AI and anxiety'. This time series study employed Box-Jenkins time series modeling to forecast long-term interest through the end of 2024.
Results
Within the United States, AI interest steadily increased throughout 2023, with some anomalies due to media reporting. Through predictive models, the study found that this trend is predicted to increase 114% through the end of the year 2024, with public interest in AI applications being on the rise.
Conclusions
According to the study, awareness of AI has drastically increased throughout 2023, especially in mental health. This demonstrates increasing public awareness of mental health and AI, making advocacy and education about AI technology of paramount importance.

Enhanced External Counterpulsation as a Novel Treatment for Heart Transplant Candidates with Ischemic Heart Failure with Reduced Ejection Fraction
Ali, A., Farooqui, S., & Khalid, E. Circulation, 150(Suppl_1), Abstract 4144084
This research, co-authored by CRI team members Dr. Asif Ali, Sami Farooqui, and Emad Khalid, presents a case study of a 58-year-old female with heart failure with reduced ejection fraction (HFrEF) of 20% due to ischemia, not amenable to revascularization. The patient refused heart transplant surgery and underwent 35 sessions of Enhanced External Counterpulsation (EECP) over seven weeks. Post-EECP, she showed improvements in her Canadian Cardiovascular Society (CCS) score, New York Heart Association (NYHA) class, and ejection fraction (EF), leading to her delisting from heart transplantation. The case highlights EECP as a noninvasive outpatient treatment for ischemic HFrEF patients awaiting heart transplantation, suggesting its potential as an early intervention.
