Having a pet cat might doubtlessly double your threat of growing schizophrenia, in keeping with a brand new research.
Researchers from the University of Queensland, Australia, performed a overview 17 research from 11 nations together with the US and the UK over the previous 44 years.
They discovered those that have been uncovered to cats earlier than the age of 25 have been round twice as more likely to develop schizophrenia.
Lead creator Dr John McGrath stated: ‘We found an association between broadly defined cat ownership and increased odds of developing schizophrenia-related disorders.’
In 1995, a paper proposed that some cases of schizophrenia may be caused by viruses that come from home cat, by way of the parasite Toxoplasma gondii, which may enter the physique through a chunk.
The parasite can enter the central nervous system and have an effect on neurotransmitters within the mind, resulting in persona modifications, psychotic signs and psychiatric problems akin to schizophrenia.
However, the authors stated that additional analysis was wanted to substantiate the potential relationship, and since then, not all research have discovered the affiliation.
But the crew behind the latest meta-analysis – an summary of a number of research – discovered ‘a significant positive association between broadly defined cat ownership and an increased risk of schizophrenia-related disorders.’
They wrote: ‘After adjusting for covariates, we found that individuals exposed to cats had approximately twice the odds of developing schizophrenia.’
However, you will need to be aware that the findings throughout the research have been inconsistent, and 15 of the 17 case research used have been case-control, which can’t decide a trigger and impact because it doesn’t have a look at exterior components.
For instance, one research within the US checked out 354 college students and located no affiliation between cat possession and scores on a schizotypy scale – a questionnaire that helps diagnose schizophrenia.
It did discover, nevertheless, when evaluating these bitten by a cat to these not bitten, the bitten subgroup had greater scores on the dimensions.

‘In conclusion, our review provides support for an association between cat ownership and schizophrenia-related disorders,’ they stated.
