About this trial

NMDA receptor antibody encephalitis is a rare autoimmune neurological disease of the central nervous system with an estimated incidence of 1.5 people per million per year. Patients with anti-NMDAR encephalitis experience an acute phase of the disease characterized by psychosis, memory loss, seizures, autonomic nervous system instability, or coma. Since the discovery of this disease 14 years ago by Prof. Dalmau, the clinical presentation of the acute phase has been well characterized, while the psychosocial impact of the disease remains largely unexplored.

Currently, there are few cohort studies of patients that have identified persistent cognitive impairment as a factor impacting remission after the acute phase. Given the scarcity of information concerning the post-acute phase, it is therefore essential to determine the long-term social and psychological outcomes and their daily effects on the social and functional life of this severe disease. This is especially important as the patients are young, with a median age of 21 years, and may face lasting limitations potentially detrimental to their success in professional, educational, or social environments.

Time frame
At inclusion
3

Analysis of cognitive assessments and psychosocial questionnaires of patients with anti-NMDAR encephalitis after the acute phase of the disease - PROMS questionnaires - FSS questionnaire

FSS questionnaire (stands for "fatigue severity scale") assesses fatigue in patients. Questionnaire is composed of 9 items graded on a scale from 1 to 7. Score varies from 9 to 63. The higher the score, the strongest the fatigue.

Time frame
At inclusion
4

Analysis of cognitive assessments and psychosocial questionnaires of patients with anti-NMDAR encephalitis after the acute phase of the disease - PROMS questionnaire - GAD7

GAD7 questionnaire (stands for "Generalized Anxiety Disorder 7") assesses anxiety in patients. Items are rated on a scale of 0 to 3. Score varies from 0 to 21. The recommended threshold for estimating generalised anxiety is 10. Thresholds: No anxiety: 0-4 points; Mild anxiety: 5-9 points; Moderate anxiety: 10-14 points; Severe anxiety: 15-21 points.
