Scientists Link ‘Cat’ Parasite to Common Neurological Disorders

‘A new study shows that Toxoplasma gondii—a brain parasite often transmitted to humans by cats—triggers various changes in the human brain which potentially allow the pathogen to exacerbate several pre-existing neurological conditions. It’s a worrisome finding given that nearly one in ten Americans may be infected with the parasite, but more work is needed to assess T. gondii’s full impact on human health.

The new research, published recently in Scientific Reports, links T. gondii with several brain conditions, including Alzheimer’s, Parkinson’s, epilepsy, and even some cancers. The research, which involved 32 scientists across 16 institutions in the US, UK, Canada, and Australia, identifies key vulnerabilities in the human brain that enable the parasite to alter the course of a disease, and potentially make it even worse. The findings could eventually serve as a guide to help scientists design medications and interventions to repair and prevent neurological damage inflicted by T. gondii on the human brain…’
