A recent study from the University of California, Riverside, reveals that infection by the common brain parasite Toxoplasma gondii significantly disrupts neural communication and may contribute to neurological disease in susceptible individuals. The findings, published in June 2025, show that the parasite causes a notable increase in the neurotransmitter glutamate in the brain, which is tightly regulated by specialized cells called astrocytes.
Glutamate is crucial for excitatory signaling between neurons, but excessive extracellular glutamate is associated with brain injury and neurodegenerative diseases such as epilepsy, multiple sclerosis, and amyotrophic lateral sclerosis (ALS). The study suggests that Toxoplasma infection could act as a trigger for neurological disorders in people already predisposed to such conditions.
Toxoplasma gondii is a single-celled parasite that chronically infects neurons and is carried by a significant portion of the global population—up to 30% in the United States and as much as 80% in countries like France and Brazil. While most healthy individuals control the infection without symptoms, it poses serious risks to immunocompromised people and pregnant women, who can pass the infection to their unborn children, potentially causing severe congenital defects or even fetal death.
The research highlights the importance of understanding how chronic infections like toxoplasmosis may subtly alter brain chemistry, potentially leading to long-term neurological consequences.
