Antineuronal Antibodies

Antineuronal antibodies are immune system proteins that mistakenly target and attack nerve cells in the brain or nervous system. Normally, antibodies help fight infections, but in certain cases, they can misidentify healthy nerve tissue as harmful. This immune response can lead to neurological symptoms such as behavioral changes, movement problems, or cognitive issues. These antibodies are often associated with autoimmune neurological disorders, sometimes linked to cancers or infections. Diagnosing involves detecting specific antineuronal antibodies in the blood or cerebrospinal fluid, guiding appropriate treatment to reduce immune system activity and improve neurological function.
