Irene Jimenez Padilla, a former nurse at Guy’s and St. Thomas’ hospitals in London, was plagued by traumatic flashbacks to her time on the frontlines of the coronavirus pandemic. However, a simple computer puzzle game has since transformed her mental health and offered a novel form of therapy.
Padilla’s memories were dominated by images of patients who had passed away under her care, their deaths marked by immense suffering. These disturbing flashbacks were so persistent, she likened them to a “pesky fly” that kept buzzing relentlessly in her mind. Unable to control the intrusive thoughts, Padilla turned to an innovative treatment: playing Tetris, the classic puzzle game where players rotate and arrange colored blocks.
After several weeks of playing, the results were profound. Though the memories of the pandemic remained, Padilla no longer experienced the same overwhelming anxiety and distress. “It was so effective,” she says, reflecting on how the digital intervention alleviated her emotional turmoil. “All those faces, all those noises—they’re gone.”
Tetris-based therapy is part of a growing field of digital mental health treatments that leverage new technologies to address emotional and psychological challenges. While still in its early stages, these treatments are showing promising results and hint at new possibilities for mental health care.
The Rise of Digital Interventions
Many mental health professionals are exploring digital solutions in response to the limitations of traditional therapies, which are primarily focused on medication and psychotherapy. While effective, these methods are not always scalable or accessible, and they often do not address the increasing global demand for mental health care. The rapid growth of digital tools aims to fill this gap.
Miranda Wolpert, director of mental health at the charity Wellcome, believes that the next generation of treatments will revolutionize mental health care. “We are now at a tipping point,” Wolpert says. “The types of mental health interventions you’ll see in five years may look very different from what you see now.”
However, as with any emerging technology, these digital therapies are at various stages of acceptance by regulators, clinicians, and patients. Larger studies will be needed to prove their long-term effectiveness and cost-efficiency. Despite this, proponents argue that technology could bridge the widening gap between the growing need for mental health services and the current limitations of traditional treatment options.
Some mental health conditions, such as schizophrenia, remain particularly challenging to treat. Although psychotherapy can have notable effects, its impact is often difficult to quantify, and it is costly and time-consuming for many patients. Moreover, the development of new drugs for mental health disorders has been slow. For instance, when the US Food and Drug Administration approved the schizophrenia drug KarXT in September, it marked the first significant breakthrough in over 70 years.
Efforts to use psychedelic substances, such as MDMA, to treat conditions like PTSD have also been met with setbacks. Earlier this year, US authorities rejected the use of MDMA for PTSD treatment, highlighting the ongoing challenges in finding effective and reliable mental health solutions.
Technology’s Transformative Role
Despite these challenges, the potential of technology in mental health care is undeniable. According to the US National Institute of Mental Health (NIMH), technology has “opened a new frontier in mental health care and data collection.” The NIMH has awarded more than 400 grants for technology-enabled interventions, underscoring the growing investment in this area.
David Crepaz-Keay, head of research and applied learning at the UK’s Mental Health Foundation, emphasizes the role of big data and artificial intelligence (AI) in identifying at-risk populations and enabling early interventions. “Advances in technology and innovative thinking are transforming mental health care,” Crepaz-Keay says. “Combined with apps, wearables, and other digital tools, these innovations are expanding access, personalizing care, and supporting the protection of mental health.”
Avatar Therapy: A Digital Approach to Psychosis
One of the most promising digital innovations in mental health is Avatar therapy, particularly for individuals experiencing auditory hallucinations, a common symptom of psychosis. Patients often hear persistent, critical voices that can lead to significant distress and feelings of worthlessness. Traditional treatments, including medication and psychotherapy, are not always effective for these individuals.
In Avatar therapy, patients create a digital avatar to represent the voice they hear. They then engage in conversations with this avatar, with the therapist providing the script for the dialogue. The key innovation of Avatar therapy lies in the sense of control it gives the patient by externalizing an internal experience. According to Tom Ward, a clinical psychologist at King’s College London who is involved in Avatar therapy research, this approach allows individuals to confront their voices in a tangible way.
“What inspires this idea is that people who hear voices experience a very convincing communication with another,” Ward explains. “But, by definition, this experience is not shared with anyone else—not a mental health professional or even a loved one. By externalizing that experience, Avatar therapy creates a shared reality, providing an opportunity for the person to regain control.”
The Road Ahead
While these technological interventions are still in their nascent stages, they represent a promising shift in how mental health care is delivered. By harnessing the power of digital tools, researchers are hopeful that mental health treatments can become more accessible, personalized, and effective.
As the demand for mental health services continues to grow, these new technologies may offer vital support, particularly for those who have not responded well to traditional therapies. As more studies unfold and the field progresses, the future of mental health care may look very different—and far more innovative—than it does today.
