Antiphospholipid Antibodies in Mental Disorders

Area of Science:

• Neuroscience
• Immunology
• Psychiatry

Background:

• Antiphospholipid syndrome (APS) is characterized by thrombotic events.
• Neuropsychiatric manifestations are increasingly recognized in patients with antiphospholipid antibodies (aPL).
• Existing research on psychiatric conditions associated with aPL is limited and of variable quality.

Purpose of the Study:

• To explore the association between antiphospholipid antibodies (aPL) and psychiatric disorders.
• To review current evidence on neuropsychiatric manifestations in aPL-positive individuals.
• To highlight the need for further high-quality clinical research.

Main Methods:

• Review of existing literature on aPL and neuropsychiatric conditions.
• Analysis of findings from animal models and human case studies.
• Examination of brain imaging and cellular interaction data.

Main Results:

• Animal models suggest a link between aPL and hyperactivity/anxiety.
• Human studies indicate a potential risk of psychosis, depression, and anxiety disorders.
• Brain imaging shows hypoperfusion and white matter changes in affected individuals.
• Direct interactions between aPL and brain cells (neurons, glial cells) are demonstrable.

Conclusions:

• The association between psychiatric diseases and aPL is increasingly plausible.
• Significant gaps remain in clinical research quality and scope.
• Therapeutic strategies for managing these psychiatric manifestations are currently unresolved.
