What Are Autoimmune Disorders? Written by Matthew Hoffman, MD Medically Reviewed by Jennifer Robinson, MD on May 05, 2022 Immune system disorders cause abnormally low activity or over activity of the immune system. In cases of immune system overactivity, the body attacks and damages its own tissues (autoimmune diseases). Immune deficiency diseases decrease the body's ability to fight invaders, causing vulnerability to infections. In response to an unknown trigger, the immune system may begin producing antibodies that instead of fighting infections, attack the body's own tissues. Treatment for autoimmune diseases generally focuses on reducing immune system activity. Examples of autoimmune diseases include: Rheumatoid arthritis . The immune system produces antibodies that attach to the linings of joints. Immune system cells then attack the joints, causing inflammation , swelling, and pain. If untreated, rheumatoid arthritis causes gradually causes permanent joint damage...

Freshwater 'Brain-Eating' Amoeba: What to Know No need to avoid lakes and rivers -- disease experts say infection is exceedingly rare From the WebMD Archives By Dennis Thompson HealthDay Reporter THURSDAY, July 14, 2016 (HealthDay News) -- The headlines are terrifying, and the story details are even worse as you read about a child who goes for a swim in a lake or river and then falls prey to a "brain-eating amoeba."
