Toxoplasma gondii is a protozoan parasite that affects about one-third of the world’s human population. Recent studies have shown possible consequences of T. gondii infection, including associations with brain cancer and neuropsychiatric conditions such as schizophrenia, bipolar disorder, and depression. T. gondii affects neurological well-being, particularly through its capacity to modify neurotransmitter pathways and provoke neuroinflammation. Source: Rabiei , P.; Esmaeilpour-Bandboni, M. Para
