The Surprising Link Between Age of Onset and Suicide in Schizophrenia

Schizophrenia, a severe mental disorder affecting roughly 1% of the global population, can emerge at various life stages. While early onset is common, the connection between the age at which schizophrenia begins and the likelihood of suicide attempts remains murky. A groundbreaking study aims to shed light on this crucial issue.

The Study at a Glance

In a comprehensive study involving 949 stable chronic schizophrenia patients, researchers systematically categorized participants based on their age at onset—those diagnosed at or before 25 years were labeled youth-onset (YO), while those diagnosed later were classified as non-youth-onset (NYO). Utilizing a variety of assessments like the Positive and Negative Syndrome Scale (PANSS) and the Insomnia Severity Index (ISI), the researchers sought to identify differences in the prevalence of suicide attempts between the two groups.

Key Findings: No Difference in Suicide Rates, but What About Risks?

Surprisingly, the study unveiled that both YO and NYO groups exhibited similar suicide attempt rates: 11.1% for YO and 9.5% for NYO. However, the factors influencing those attempts diverged significantly. YO patients with a history of suicide attempts exhibited notably higher scores on various PANSS components—specifically, those related to positive symptoms and depression/anxiety.
