Mysterious Link Between Cat Ownership and Schizophrenia Risk Identified in New Research
PARIS – A new analysis of existing research suggests a potential connection between cat ownership and an increased risk of schizophrenia, though scientists emphasize correlation does not equal causation and further inquiry is crucial. The Australian study, highlighted by Futura Sciences, reveals an intriguing, yet complex relationship, prompting researchers to explore potential biological and environmental factors at play.
The review found inconsistent results across studies, with varying levels of quality. A critical period of exposure appears to be between 9 and 12 years old, though this remains poorly defined. While an American study of 354 psychology students found no direct link between cat ownership and schizotypy scores – a personality trait associated with schizophrenia – it did reveal higher scores on certain psychological scales among those who had been bitten by a cat.
Researchers have long considered Toxoplasma gondii – a parasite commonly found in cat feces – as a potential culprit. Though, the new analysis points to other possible pathogens, including Pasteurella multocida, a bacteria present in cat saliva, as potentially influencing psychological factors.
Study authors caution against unwarranted alarm, stressing the need for large-scale, high-quality research to better understand the underlying mechanisms. They recommend future studies focus on: representative samples, a deeper understanding of potential mechanisms, and exploration of other environmental factors impacting mental health.
This research underscores the complex interplay between our surroundings, animal companions, and mental wellbeing, opening new avenues for medical investigation.
