Leucine-rich, glioma inactivated 1-antibody encephalitis can manifest with psychosis and seizures. Early recognition of this autoimmune encephalitis is crucial for timely treatment.
Area of Science:
- Neuroimmunology
- Neurology
Background:
- Autoimmune encephalitis is a group of disorders caused by antibodies targeting neural surface antigens.
- Leucine-rich, glioma inactivated 1 (LGI1) antibody-encephalitis is a common form of autoimmune encephalitis.
Observation:
- A young male patient presented with acute psychosis, memory deficits, and faciobrachial dystonic seizures.
- Clinical presentation mimicked primary psychiatric disorders.
Findings:
- Magnetic resonance imaging (MRI) demonstrated hippocampal lesions.
- Electroencephalography (EEG) showed frontotemporal slowing.
Implications:
- This case highlights the importance of considering LGI1 antibody-encephalitis in patients with unexplained psychosis and neurological symptoms.
- Prompt diagnosis and immunotherapy can lead to favorable outcomes.

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

Antibody Structure and Classes
The basic structure of an antibody consists of four protein chains: two identical heavy chains and two identical light chains. These chains are held together by disulfide bonds and other non-covalent interactions, forming a Y-shaped structure.
