Toxoplasmosis has been associated with various brain function impairments and neuropsychiatric issues, but the exact presence of the parasite Toxoplasma gondii in the human brain remains unclear.
A study aimed to detect parasite DNA in brain tissue from autopsied cases correlated it with risky behaviors and alcohol use, utilizing 97 male subjects divided into distinct groups based on their behaviors.
Findings revealed a 16.5% prevalence of parasite DNA in brain samples, correlating with risky behaviors leading to death, but not with excessive alcohol consumption, suggesting potential effects of latent toxoplasmosis on behavior.
