Perceptual distortions in late-teens predict psychotic symptoms in mid-life

Schizophrenia is often diagnosed well into adulthood, typically from the late teens to early 40s. Are there early indicators that could help predict which individuals will go on to develop this serious mental illness?

Researchers in clinical psychology and psychiatry have long sought to answer this question. New research by Distinguished Professor Mark F. Lenzenweger at Binghamton University (State University of New York at Binghamton) and Weill Cornell Medical College could point the way.

In “Schizotypy 17 years on: Psychotic symptoms in midlife,” recently published in the Journal of Abnormal Psychology, Lenzenweger explored the development of psychotic symptoms in 191 individuals with no prior history of psychosis; first assessed in their young adulthood (age 17-18), study participants were assessed a second time in their mid-30s.

Lenzenweger found that subtle differences in perception during their late-teen years predicted the development of hallucinations, delusions, and, in some instances, psychosis later in life. These early perceptual distortions included a heightened awareness of sound or color, uncertainty about the boundaries of one’s body, feeling that the world around them is tilting, and similar experiences.
