Summary: | Background: Neurological involvement has been found in many autoimmune diseases, with psychiatric abnormalities such as anxiety, depression, psychosis, and cognitive dysfunction.
Patients and Methods: Here, we describe a series of 5 consecutive cases of autoimmune diseases presenting with psychiatric symptoms as the predominant manifestation.
Result: Our case series suggests that psychiatric symptoms, mainly depression, can be one of the presenting symptoms of several autoimmune diseases that often cause a significant delay in diagnosis.
Conclusion: Any patient, particularly females, with a newly detected psychiatric disorder that responds poorly to medical management should be properly examined for underlying primary systemic autoimmune diseases.
