It turns out that the risk of developing mental disorders can be predicted from paresthesia in young people

In recent years, research and development on psychiatric disorders have been progressing, such as the discovery of genes involved in the development of psychiatric disorders and the development of tools for analyzing the risk of developing schizophrenia. Meanwhile, a research team at Binghamton University announced that 'the onset of mental disorders can be predicted from paresthesia such as'being hypersensitive to sound and color'in young age.'

Among the many mental disorders, schizophrenia is known to develop in the late 10s to early 40s. To develop a method for predicting the risk of developing schizophrenia, the research team conducted a follow-up study that evaluated the mental status of 191 people aged 17 to 18 years and evaluated the mental status again 17 years later.

As a result of the follow-up survey, in the late teens, there were perceptual distortions such as 'becoming sensitive to sound and color', 'feeling uncertainty about the boundary between the body and the world', and 'feeling that the world is tilted'. If confirmed, it was found that people in their thirties are more likely to develop mental disorders in general, not just schizophrenia. At the same time, it has become clear that even if you have depression in your teens, it has nothing to do with the onset of mental illness in your 30s.

Mark F. Lenzenweger, a member of the research team, said, 'Symptoms such as hallucinations and delusions in middle age, even when people who did not have mental illness as a teenager showed very slight impairment of perception. We found that it was easier to show, 'he said, claiming that this follow-up study found a way to predict the onset of mental illness.

According to the research team, there are about 3.5 million schizophrenia patients in the United States, and the total annual medical expenses are 155 billion dollars (about 17 trillion yen). 'The results of this study provide a foothold for research into the biological factors that cause mental illness and the relationship between real-world experience and sensory deficits,' said Lenzenweger. 'Understanding the nature of dysesthesia.' Helps us understand the mechanics of developing schizophrenia and other psychiatric disorders, 'he said, suggesting that this finding may be useful for future psychiatric disorder research.
