Is OCD linked to Immune System Problems?
New research provides insight into potential causes of OCD. During the past few years, scientists have learned that this anxiety disorder may be linked to immunological problems.
Several small studies have found that patients with OCD have smaller numbers of some immune system cells and signs of autoimmune activity.
Last year, four scientists from Firat University, a Turkish college, published research showing immunological differences between OCD patients and people who had no physical or mental problems.
By using blood tests, the scientists found that patients with OCD had lower levels of neutrophils, which are white blood cells that help the human immune system fight off invading microorganisms.
The mean neutrophil count of the OCD study subjects was lower compared to that of the control subjects say the scientists running the study.
