Neuro-Immuno Deficiency Syndrome, (also known as NIDS), is a rare, incurable and potentially fatal disease. NIDS is an intended medical classification for illnesses or disorders (that may currently have psychiatric or developmental labels) that are actually caused by a complex neuro-immune, a complex viral, autoimmune-like illness affecting cognitive and body functions in children and adults. Some of these diseases are labelled as; Autism, Pervasive Developmental Disorder (PDD), ADD or ADHD, Chronic Fatigue Syndrome (CFS/CFIDS), as well as other multiple related disorders. Many classic autoimmune diseases may have a treatable NIDS component. The symptoms of NIDS vary and can affect multiple areas of a child's development and overall health and well-being.
