Anti-dipeptidyl-peptidase-like protein 6 encephalitis, a rare cause of reversible rapid progressive dementia and insomnia
We present a case of a 72-year-old male with anti-DPPX encephalitis who developed rapidly progressive cognitive decline, psychiatric and sleep problems, severe abdominal pain and diarrhea. Antibodies against DPPX were positive both in serum and cerebrospinal fluid. 18F-FDG PET-MR imaging indicated hypometabolism in the bilateral temporal lobes and thalamus. No related tumors were found, and the patient responded to immunotherapy without relapse at the 3-year follow-up.
