Antineuronal Antibody Syndromes

Antineuronal antibody syndromes are a group of neurological conditions where the immune system mistakenly creates antibodies that attack the brain or nervous system. These antibodies target specific proteins on nerve cells, disrupting normal brain functions like movement, memory, or behavior. Often, these syndromes are linked to underlying tumors or cancers, which may trigger the immune response. Treatment typically involves removing or controlling the tumor and using immunotherapy to reduce harmful antibodies, helping improve symptoms and neurological function. Recognizing these syndromes early is essential, as they can often be managed effectively with appropriate medical care.
