A new category of autoimmune diseases affecting the brain is leading psychiatrists to reconsider some diagnoses. According to Dr. Chris Hahn from the Cumming School of Medicine at the University of Calgary, patients with autoimmune encephalitis, although rare, often show psychiatric symptoms, which can result in misdiagnosis as a mental illness.
One individual, Nora Scott from High River, Alberta, experienced this firsthand. Initially, everything seemed fine for Scott until she began struggling to sleep and felt her mind constantly racing. This led her to take a break from work and focus intensely on cleaning her home, displaying unusual behaviors like excessive planning and spending.
Following a hospitalization and a diagnosis of bipolar disorder, it took another four years and a second hospital stay for Scott to be correctly diagnosed with anti-NMDA receptor encephalitis, a rare autoimmune disease. This condition involves the immune system attacking the brain, often affecting mood and perception, which can mimic mental disorders.
Dr. Hahn emphasizes the difficulty of diagnosing autoimmune encephalitis and the importance of accurate diagnosis to avoid misattributing symptoms to mental health conditions. Efforts have been made to develop national guidelines for identifying autoimmune encephalitis to improve diagnostic accuracy.
Despite the stigma surrounding mental health conditions, it is crucial to differentiate between autoimmune encephalitis and mental illness for appropriate treatment. While autoimmune encephalitis is treatable, mental illnesses can also be managed effectively with proper care. Nora Scott’s case highlights the significance of accurate diagnosis and the impact it can have on a patient’s life.
