<unk> , also known as Anti-ANNA1<unk>  encephalitis, is an uncommon form of brain inflammation that is<unk>  with an underlying cancer. It can cause psychiatric symptoms such as depression, anxiety, and hallucinations. It can also produce neurological symptoms such as confusion, memory loss, weakness, sensory loss, pain, seizures, and problems coordinating the movement of the body. While its cause is unknown, the most common hypothesis is that it is caused by an immune system attack on the nervous system. This immune system attack is linked to cancer in most cases, usually small cell lung carcinoma. The condition's namesake, the anti-Hu antibody, is a protein made by the host's immune system, and it is present in virtually all cases. Treatment is focused on removing the underlying cancer and suppressing the immune system. Its prognosis remains quite poor, with most patients dying less than a year after diagnosis.
