X-linked agammaglobulinemia (XLA) is a primary immunodeficiency disorder caused by a mutation in the Bruton agammaglobulinemia tyrosine kinase gene that results in severe B-cell deficiency. So far, neurological complications of XLA have been primarily related to acute and/or chronic central nervous system enteroviral infections. In the last few years a progressive neurodegenerative syndrome of unknown etiology has been described in XLA patients. We describe and present a video of an XLA patient who developed a fatal dementing, dystonia-Parkinsonism syndrome 14 years into his immune disorder. Physician awareness of this rare syndrome may lead to its better characterization and management.

Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is a recently identified auto-immune disorder characterised by severe memory deficit, a decreased level of consciousness, seizures, autonomic dysfunction and movement disorders. Three girls with the disorder are reported; they were aged 4 years, 5 years and 10 months. The 10-month-old infant who is one of the youngest patients reported with anti-NMDAR encephalitis worldwide, had MRI features suggestive of herpes simplex encephalitis (known to trigger anti-NMDAR encephalitis), but CSF PCR for herpes simplex was negative. All the patients presented with seizures, behavioural change, regression of speech, dystonia and choreo-athetosis. Anti-NMDAR antibodies were detected in all patients' sera and cerebrospinal fluid (CSF). Intravenous immunoglobulin, corticosteroids and rituximab were administered at different intervals. Cases 1 and 2 made a full recovery, but case 3 has mild motor and speech delay. Patients who present with encephalopathy, seizures and movement disorders should be tested for anti-NMDAR antibodies in serum and CSF in addition to being screened for herpes simplex encephalitis.
