Neuro-Immune Deficiency Syndrome (ＮＩＤＳ：先天性免疫不全症候群 Senten-sei Meneki Fuzen Shōkōgun?, lit. "NIDS: Neuro Immunodeficiency Syndrome") is a fictional, incurable and fatal disease.
Over fifty years ago, Maria Robotnik was diagnosed with Neuro-Immune Deficiency Syndrome, much to her granfather's worry, and was expected not to recover from it. Medical treatment research for the sickness was conducted aboard the Space Colony ARK, but they were unable to yield a cure. New hope for this research came however when Professor Gerald Robotnik accepted from the President of the United Federation to lead Project Shadow to discover an "immortality formula." Gerald hoped that he could use this immortality research to develop a cure for Neuro-Immune Deficiency Syndrome as a byproduct. As such, he and his colleagues began work on creating an ultimate life form endowed with immortality and the potential to create such a cure. However, the project ultimately failed when the military forcibly shut it down, eliminating those who were involved.
Based on its name, it is most likely a disease that affects the nervous system while also weakening the immune system (through the reduction of a person's antibody count), making the patient more susceptible to other diseases, as is evidenced by its name ("neuro" comes from the Greek word neuron, meaning "nerve" and in medical terms, refers to the brain and nervous system; immunodeficiency implies a weak immune system). It is said that medical treatment for it was difficult to provide fifty years ago.
