Participants of a prospective cohort in post-acute phase of the Antibody-mediated NMDA Receptor Encephalitis that will received a behavioral treatment.

Remote cognitive rehabilitation program will be performed through an online validated platform (Guttmann NeuroPersonalTrainer: https://gnpt.es/) run by the psychologists team. This is a Sanitary Product with CE certification (Sanitary Product RPS/430/2014; International Patent \[PCT/ES2008/00677\]) and here will be used within its approved indications. The rehabilitation program will increase in difficulty and decrease in frequency during the first year of follow-up (V1-V3).

The encephalitis mediated by antibodies against the NMDA receptor (NMDARe) predominantly affects young adults and children resulting in severe neurologic and psychiatric deficits. After overcoming the acute stage, patients are left with long-lasting behavioral, cognitive, and psychiatric alterations with important socio-family-economical implications. Here investigators postulate that a better knowledge of this stage will improve treatment decisions and outcome.

In Aim 1, the post-acute stage will be clinically characterized, tools to remotely follow cognitive, behavioral and psychiatric deficits will be provided, and the impact of cognitive rehabilitation will be assessed.

In Aim 2, biomarkers (autoimmune, inflammatory, neuronal injury) will be identified as signatures of the acute and post-acute stages.

In Aim 3, a mouse model of NMDARe will be used to determine the underlying mechanisms and treatment of the postacute stage.

IED Total Errors (Adjusted): The total number of times that the subject chose a wrong stimulus - i.e. one incompatible with the current rule, adjustment for every stage that was not reached. Lower is better. Total Errors Adjusted = Total Errors (problems reached) + \[(number of unreached problems) \* (25)\] This is a measure of the subject's efficiency in attempting the test. Subjects failing at any stage of the test will have had less opportunity to make errors. The adjustment is carried out to compensate for this missing data, and provide a more comparable error score to subjects completing all stages of the test..

This is quantified from the participant responses in the working memory task. Errors in the report of memorized locations are multiplied by the sign of the difference in locations in the previous and current trials and then averaged over the whole session to obtain the index of serial bias. We expect increases in this index as patients improve clinically.

This is quantified by training decoders of memorized locations on EEG signals acquired over several electrodes during the working memory task. Reactivations are the average strength of the decoders during the fixation period of the next trial. We expect that EEG reactivations increase as patients improve clinically and correlate with the serial bias index.

This is quantified from EEG recorded during sleep, by detecting individual slow-waves and estimating their strength, and then computing the rate of growth of this strength in the first slow-wave periods in the night. We expect the rate of growth of slow waves to increase as patients improve.
