AI language models are paving the way for advanced diagnostic procedures in mental health. At the forefront of this evolution is a new study by scientists from the UCL Institute for Neurology, which suggests that these AI language models might potentially revolutionize the diagnosis of schizophrenia. The research, originally published by ScienceDaily, reveals the in-depth utilization of AI in characterizing subtle signatures of speech patterns among patients diagnosed with this severe psychiatric disorder.
Psychiatric diagnosis largely depends on interviews with patients and their close ones, with little pertinence given to other types of tests. This process, while necessary, impedes deeper exploration into the causative factors of mental disorders and monitoring of treatments. The researchers at UCL are attempting to transform this scenario by leveraging AI language models.
In their study, the researchers engaged 26 schizophrenia patients and an equal number of control participants in two verbal fluency tasks. The participants were directed to name as many words as possible fitting in a specific category or starting with a designated letter within five minutes.
The team then utilized an AI language model, trained on substantial quantities of internet text, to analyze the responses from the participants. They found that the responses from the control participants were more predictable by their AI model compared to those from schizophrenia patients, and this discrepancy was larger in patients demonstrating more acute symptoms.
These findings propose an intriguing hypothesis, suggesting that the observed difference could be an indicator of how the brain learns connections between memorizations and ideas, storing them as cognitive maps. The research not only highlights the potential of AI language models in diagnosing schizophrenia but also its extended use in understanding various other psychiatric disorders.
The team's lead author, Dr. Matthew Nour, emphasized the transformative potential of AI language models such as ChatGPT in psychiatry, a field intrinsically connected to language and meaning. Schizophrenia, affecting over 24 million people worldwide and over 685,000 in the UK, presents with an array of symptoms, including hallucinations, delusions, confused thoughts and changes in behavior.
The team at UCL and Oxford now looks forward to testing this technology in a larger sample size across the broader speech setting. If these methods prove to be both safe and robust, Dr. Nour believes that they can be integrated into clinical settings within the next ten years. The study was supported by 'Wellcome'.
