The past three years have witnessed a profound evolution in the application of Artificial Intelligence (AI) in healthcare, particularly in mental health. However, despite the technological advancements, the mental health tech space globally saw a funding decline worth $713 million in 2023 year-to-date (YTD), a 52.5 percent drop from $1.5 billion in 2022 and a 79 percent fall from $3.43 billion in 2021. This funding decrease, while concerning, might be counterbalanced by the increasing adoption of AI technologies in mental healthcare, potentially boosting the sector in the coming months. Let's delve deeper into whether AI could further fortify mental healthcare's footprint in this evolving realm.

Importance of Mental Health and Technological Advancements

Individuals and corporations globally recognize the importance of proper mental health for ensuring overall well-being and societal development. Over the past three years, mental health tech startups have played a crucial role in increasing the affordability and accessibility of mental healthcare. The World Federation of Mental Health emphasized this by naming the theme for World Mental Health Day (WMHD) 2023, celebrated on October 10, as "Mental Health is a Universal Right." Startups innovating in this sector are pivotal in achieving this goal through new technologies.

Funding Trends in the Mental Health Tech Space

A recent report by Tracxn Technologies highlights that the global mental health tech space peaked in funding at $4.7 billion in 2021. Similar to other healthcare businesses, mental health startups saw a significant rise in demand in 2021 due to the pandemic's mental health impact. However, funding plunged to $713 million YTD in 2023, primarily due to the ongoing economic slowdown and other macroeconomic factors affecting global cash flow.

Most of the funding this year has come through late-stage investments, totaling $340 million, a 35 percent reduction from $527 million in 2022 and an 85.8 percent drop from $2.4 billion in 2021. Additionally, 2023 has witnessed 17 acquisitions to date, a 22.7 percent decline from 22 acquisitions in 2021. The numbers have remained consistent compared to 2022. Currently, the US leads with the most companies in this space (2,360), followed by the UK (662) and India (429).

Societal Benefits and Customization of AI in Mental Healthcare

"Beyond the monetary gains, investing in mental health startups can certainly garner profound societal benefits". By making mental healthcare more accessible and mainstream, startups can help bust age-old myths and eradicate stigmas associated with mental health issues in India. Traditional taboos around mental health are slowly being demolished, with the government and NGOs becoming more proactive in addressing these issues. This creates opportunities for startups to collaborate or receive support. AI can analyze large data sets quickly, providing personalized feedback or therapeutic suggestions based on individual user data, thus enhancing the quality of care.

Top Performing Business Models and AI's Role

Mental health teleconsultation and digital therapeutics have been top-performing business models in 2023. Teleconsultation has been vital in countries like India, where there are only 0.75 psychiatrists per 100,000 population, significantly lower than in European countries like Germany with 27 per 100,000 inhabitants. Recent research by MIT's Rosalind Picard and Massachusetts General Hospital's Paola Pedrelli has shown that AI can help reduce the rate of mental disorders. The increasing use of AI technologies is greatly enhancing accessibility to mental health professionals, and this sector could potentially see more investments as awareness rises among the masses.

"By embracing AI, psychoanalysts are better equipped to concentrate on delivering direct patient care and conducting in-depth research, which eventually improves patient outcomes, increases access to mental health services, and augments general efficiency in the field," comments Dr. Malini Saba, psychologist, philanthropist, human rights activist, and Founder and Chairman of the Anannke Foundation.

AI's Diagnostic Capabilities and Future Potential

AI tools use various mechanisms to diagnose mental health issues and trace behavioral pattern changes in subjects under treatment." These tools include electronic health records, social media activity, and search engine usage. AI can also utilize mental health-specific questionnaires and mood-rating scales to help characterize and classify mental health illnesses, such as depression and bipolar disorders. If there are any red flags like suicidal ideation, AI can activate SOS alarms and provide guidance. While most measures look effective on paper, many tools are still in research phases, and no FDA-approved or FDA-cleared AI applications currently exist in psychiatry.

Theoretically, AI can help detect neurological disorders by scanning data from patient files, dementia-screening questionnaires, and brain imaging. This could benefit patients with neurodegenerative conditions like Alzheimer's disease or various forms of Parkinsonism. AI may also facilitate monitoring compliance with and response to treatment, tracking changes in speech patterns, tremors, and limb stiffness through speech recognition and smart wearables.

Futuristic Element and Ethical Considerations

AI technology has been adopted by many Indian hospitals in their mental healthcare wings. AIIMS Delhi is designated as the Centre of Excellence for AI in healthcare. Many research projects are running at AIIMS, the Indian Council of Medical Research, Indian Institute of Technology-Delhi, and the National Institute of Mental Health and Neuro-Sciences on mental health and AI. However, AI algorithms need validation in real-world settings. These research projects' results and practical applications are yet to be viewed and verified.

While AI cannot read the human mind or thoughts, it can dissect data and decrypt patterns to draw conclusions or predictions about a person's goals or state of mind. The application of AI in mental health has a bright future. AI-driven solutions will likely continue to develop, improving personalization, accessibility, and effectiveness in mental healthcare. However, as AI technologies advance rapidly, ethical issues, data protection, and preserving the human connection in therapy will remain primary focal points. For AI to reach its optimal performance and maintain high standards of care, a partnership with mental health practitioners is imperative, believes Dr. Saba.

Conclusion

The integration of AI in mental healthcare is an evolving and promising field. Despite recent funding declines, the technological advancements and potential societal benefits make AI a valuable asset in improving mental health services. As AI-driven solutions continue to develop, ethical considerations and human partnerships will be crucial in ensuring effective and personalized mental healthcare.
