How Parasites Can Affect Mental Health

Parasites can interfere with the proper functioning of the body and its organs. When the brain or its related functions are affected by parasites, it can lead to mental health issues such as depression, anxiety, and cognitive difficulties.

For example, Cryptosporidium, a type of intestinal parasite, can cause symptoms such as nausea, headaches, abdominal pain, and fatigue. These can interfere with proper mental functioning, leading to low mood, impaired concentration, and difficulty making decisions.

Toxoplasmosis, meanwhile, is caused by a parasite that is spread through contact with cat feces. Research has linked this parasite to depression and anxiety, as well as aggression and suicide. Toxoplasmosis can also interfere with brain functions such as motor control, chemosensation, and learning and memory.
