Autoantibodies associated with psychiatric disorders.

Area of Science:

• Neuroimmunology
• Psychiatry
• Autoimmune Diseases

Background:

• Emerging evidence indicates the presence of autoantibodies against neuronal or endothelial targets in psychiatric disorders.
• These autoantibodies are increasingly recognized for their potential pathogenic role in the development of psychiatric symptoms.

Purpose of the Study:

• To review and discuss the involvement of autoantibodies in psychiatric manifestations.
• To examine the link between autoantibodies and specific conditions such as autoimmune diseases, post-streptococcal disorders, celiac disease, chronic fatigue syndrome, and substance abuse.
• To explore the role of autoantibodies in schizophrenia and autism, conditions now considered to have autoimmune origins.

Main Methods:

• Literature review and synthesis of existing research.
• Discussion of the pathogenic mechanisms of autoantibodies in psychiatric disorders.
• Analysis of the association between autoantibodies and various clinical conditions.

Main Results:

• The review consolidates evidence supporting the existence and potential pathogenicity of autoantibodies in psychiatric conditions.
• Specific associations are discussed between autoantibodies and psychiatric symptoms in autoimmune diseases, post-streptococcal syndromes, celiac disease, chronic fatigue syndrome, and substance abuse.
• The potential autoimmune etiology of schizophrenia and autism is highlighted, with a focus on relevant autoantibodies.

Conclusions:

• Autoantibodies represent a significant factor in the neuroimmunology of psychiatric disorders.
• Further research into autoantibody targets and mechanisms is crucial for understanding and potentially treating conditions like schizophrenia and autism.
• The findings underscore the importance of considering autoimmune processes in the etiology of a broader range of psychiatric conditions.
