Autoimmune encephalitis is a condition in which the body’s immune system attacks healthy tissue in the brain or spinal cord. It is a rare, dangerous disease that can cause serious physiological and psychological damage. Patients may experience neurological symptoms like seizures and memory problems. In addition to this, they may also experience psychological symptoms like psychosis, panic attacks and excessive aggression. Autoimmune encephalitis is associated with the production of antibodies to the protein on nerve cells. In some cases, it may be associated with a cancerous tumour. There are different types of autoimmune encephalitis including acute disseminated encephalomyelitis (ADEM), Hashimoto’s encephalopathy, limbic encephalitis and Rasmussen’s encephalitis. Autoimmune encephalitis does not appear to have a relationship with patient family history.
