Can Gut Parasites Change Human Behavior?

Some tiny parasites live in the gut. Scientists want to know if they can affect people. Researchers say these germs may not only change the body. They may also influence mood and behavior. This is still being studied. The work looks at how parasites interact with the gut and the brain. If the link is real, it could help doctors understand some health problems better. More research is needed before doctors can use this idea in treatment. The study is part of a project with UK research groups.
