Dalmau discovered anti-NMDA autoimmune encephalitis in 2007 after recognizing a pattern in young patients whose psychiatric symptoms masked severe neurological inflammation. These rare diseases predominantly affect young people and women, with initial symptoms mimicking psychosis, leading many patients to be misdiagnosed in psychiatric units for years.

Patients previously misdiagnosed with psychiatric disorders may receive correct treatment, reducing unnecessary psychiatric medications, improving health outcomes, and potentially lowering long-term healthcare costs for affected households.
Healthcare systems may need to update diagnostic protocols and training for neurologists and psychiatrists. Regulatory bodies may accelerate approval pathways for autoimmune encephalitis treatments. Insurance coverage policies may shift to reflect new diagnostic categories, potentially expanding reimbursement for specialized neuroimaging and immunological testing.
