Personalized Mental Health Interventions Through AI
Professor Sunil Gupta, head of AI Optimization and Materials Discovery at Deakin’s Applied AI Institute, along with his dedicated team, has introduced an innovative AI-driven approach to personalize early interventions for mental health conditions. Their methodology targets young individuals grappling with depression, anxiety, and stress, offering tailored treatment plans based on real-time data analysis.
Traditional randomized clinical trials are often time-consuming and costly, limiting their reach and scalability. Prof. Gupta’s team addresses these challenges by conducting adaptive clinical trials via smartphones. This approach not only reduces expenses but also accelerates the dissemination of effective treatments to a broader population. The AI algorithms employed ensure that these trials maintain accuracy comparable to conventional methods.
Last year, an AI-powered clinical trial was conducted across Australian universities, focusing on participants aged 18 to 25. The study tested interventions such as mindfulness, sleep regulation, physical activity, and placebo recommendations based on participants' distress and anxiety levels. The results demonstrated the AI’s capability to accurately identify the most effective intervention for each individual, highlighting the potential for personalized mental health care.

Strategic Partnerships and Data Utilization
The success of this research is partly due to the collaboration with The Black Dog Institute, a renowned organization specializing in mental health. Together, they recommended four key interventions: mindfulness, sleep improvement, diet, and exercise programs. This partnership ensures that the AI recommendations are grounded in established mental health practices.
Data collection is facilitated through a user-friendly smartphone app, where participants provide general information, including age and cultural background, alongside their levels of depression, anxiety, and stress. The AI processes this data, utilizing its statistical prowess to suggest personalized interventions. Follow-up questionnaires administered two weeks later allow the AI to assess the effectiveness of the recommended treatments, refining its algorithms for future accuracy.

Future Directions in Mental Health AI
Looking ahead, Prof. Gupta envisions enhancing the AI’s ability to detect more complex mental health issues. By incorporating behavioral data such as movement patterns and smartphone usage, the AI could potentially recommend advanced therapies like Cognitive Behavioral Therapy (CBT). This evolution aims to provide a more comprehensive and nuanced approach to mental health care.
The scalability of this AI methodology holds promise for addressing mental health challenges on a global scale. By making personalized interventions more accessible and affordable, Deakin University’s research could bridge gaps in mental health services, particularly in underserved regions.
Early Diagnosis of Cerebral Palsy Using AI
Simultaneously, Professor Truyen Tran, head of AI, Health, and Science at Deakin’s Applied Artificial Intelligence Institute, is spearheading a project focused on the early diagnosis of cerebral palsy. Utilizing machine learning, Prof. Tran’s team analyzes the movements of infants aged nine to sixteen weeks to identify patterns indicative of future disorders.
Infant movements at this stage are typically random and subtle, making them challenging to assess visually. The AI algorithms trained on thousands of annotated video clips enable the detection of specific movement patterns that may signal the development of cerebral palsy. This early identification is crucial, as interventions are significantly more effective when administered at a younger age.
In partnership with the Cerebral Palsy Alliance and various Australian hospitals, the project has amassed a substantial dataset of infant movement videos. These collaborations ensure that the AI models are trained on diverse and comprehensive data, enhancing their accuracy and reliability.

Transforming Cerebral Palsy Diagnosis and Intervention
Currently, cerebral palsy is often diagnosed when motor abnormalities become apparent during crawling and walking stages, typically between one and one-and-a-half years old. Early diagnosis through AI at nine to sixteen weeks can revolutionize treatment outcomes, allowing for interventions that mitigate the impact of the disorder as the child grows.
Prof. Tran emphasizes the potential for smartphone-based screening tools to democratize access to early diagnosis, regardless of geographic or economic barriers. In low-income countries, where early screening is particularly lacking, this technology could fill a critical gap, providing timely assessments and referrals to specialist clinicians.
The ultimate goal is to develop AI solutions that are universally accessible, ensuring that every family worldwide can benefit from early screening. With the ubiquity of smartphones, the deployment of these AI tools could become a standard practice in infant healthcare, significantly improving the prognosis for children at risk of cerebral palsy.

Future Outlook
While the advancements presented by Professors Gupta and Tran are promising, several challenges must be addressed to realize their full potential. Ensuring data privacy and security is paramount, especially when dealing with sensitive health information collected via smartphone apps. Additionally, the accuracy of AI algorithms must be continually validated across diverse populations to prevent biases and ensure equitable treatment recommendations.
The integration of AI into clinical settings also necessitates robust regulatory frameworks to oversee its application and efficacy. Ethical considerations, such as informed consent and the transparency of AI decision-making processes, must be prioritized to maintain trust and accountability in these technologies.
