My wife had anti-NMDA negative Encephalitis two years ago after suffering severe seizures out of the blue - her diagnosis in retrospect is NORSE (new onset refractory status epilepticus). She was put into an induced coma for 2 months, it took a long time before they realised it was encephalitis. Whilst she survived, her recovery is still ongoing. She was 32 when it happened and will never work again due to her brain injury and ongoing epilepsy.
