Brain Eating Amoeba is a rare and potentially fatal condition caused by an amoeba called Naegleria Fowleri. This single-celled organism lives in warm, fresh water and enters the body through the nose. Once it enters the brain, it can cause primary amebic meningoencephalitis (PAM), a deadly infection that destroys brain tissue and causes swelling in the brain. Fortunately, cases of Brain Eating Amoeba are very rare, but it is important to be aware of how to prevent this condition from occurring.
