Rehabilitation following anti-NMDA encephalitis

The Physiotherapy Process of a Plegic Patient Who Communicates with Foot Movement—A Case Report

There are no official recommendations regarding physiotherapy for encephalitis patients. However, such patients, depending on their condition, have to undergo rehabilitation preceded by a detailed functional examination. The paper describes the physiotherapy treatment of a 28-year-old female after acute encephalitis. She suffered three-limb palsy with preserved movement in the right ankle joint. The patient was admitted to a clinic that offers respiratory therapy, where she underwent a comprehensive rehabilitation process. The initial and final functional assessment was conducted based on the International Classification of Functioning, Disability and Health. The therapy aimed to enable social contacts by learning to communicate with the environment, taking advantage of learned motor skills and adapting the body to maintain a sitting position. The goals were implemented with gradual upright standing, electrostimulation of paralyzed muscles, orofacial therapy, methods of respiratory acceleration and the use of communication technologies. As a result of the physiotherapy, the patient can communicate with the environment more efficiently and showed a more assertive attitude towards the disease and greater motivation to exercise and socialize. This paper supports the importance of a rehabilitation program adapted to the needs of a patient with severe disabilities and encourages more studies in this area.

The Patient Experience of Recovery Following Anti-NMDA Receptor Encephalitis: A Qualitative Content Analysis

OBJECTIVE

The authors examined patients' perceptions of the factors affecting their recovery from anti-N-methyl-d-aspartate receptor (anti-NMDAR) encephalitis, which is a rare, severe immune-mediated neurological disorder.

METHODS

Seven patients completed semistructured interviews exploring their experience of recovery. Participants were interviewed between 7 and 41 months after the initiation of treatment. Interviews were transcribed and subjected to qualitative content analysis.

RESULTS

Facilitators of recovery included the presence of a support system and treatment-related factors. Barriers to recovery included perceived psychiatric stigma, insufficient illness education, and lifestyle disruptions to accommodate ongoing treatment. Adverse physical, psychological, and neurocognitive sequelae of anti-NMDAR encephalitis continued to affect participants' daily functioning. Most participants described strategies to manage neurocognitive deficits, fatigue, and anxiety.

CONCLUSIONS

Anti-NMDAR encephalitis contributes to persistent burden on patients, their families, and health services after the resolution of acute symptoms. Physical, psychological, and cognitive changes contribute to long-term disease morbidity. To optimize recovery and reduce disability, further attention must be directed toward illness education, reducing stigma, and role disruption. Longer-term disability support may benefit those who do not fully recover.

Assessment of long-term psychosocial outcomes in anti-NMDA receptor encephalitis

PURPOSE

The purpose of this study was to assess long-term psychosocial outcomes of anti-N-methyl-d-aspartate (NMDA) receptor encephalitis (anti-NMDARE).

METHODS

Adolescents and adults with self-reported anti-NMDARE were invited to complete an online survey distributed by relevant patient organizations. Demographic and clinical information was collected, including the diagnoses initially given for anti-NMDARE symptoms and posthospital care received. Patient-Reported Outcomes Measurement Information System (PROMIS) Psychosocial Impact Illness - Negative short form (Negative PSII) was administered to assess psychosocial outcome of anti-NMDARE. Associations between clinical factors and psychosocial outcomes were evaluated.

RESULTS

Sixty-one individuals with anti-NMDARE age 15 years and above participated. Mean age was 33.7 years (standard deviation [SD]: 12.8), and participants were predominantly female (90.2%, n = 55). Mean T-score on PROMIS Negative PSII was 60.7, >1 SD higher (worse psychosocial function) than that of the provided normalized sample enriched for chronic illness (50, SD: 10). Initial misdiagnosis of anti-NMDARE symptoms was associated with decreased odds (odds ratio [OR]: 0.11, p < 0.05), and follow-up with a psychiatrist after hospitalization with increased odds (OR: 8.46, p < 0.05), of return to work/school after illness. Younger age of symptom onset and presence of ongoing neuropsychiatric issues were predictive of worse Negative PSII scores (p < 0.05).

CONCLUSION

Individuals with anti-NMDARE demonstrate poor psychosocial outcomes, yet there are no current standards for long-term assessment or management of such symptoms in this population. These findings highlight the need for use of more comprehensive outcome measures that include assessment of psychosocial function and the importance of developing interventions that address this domain for individuals with anti-NMDARE.

Pediatric Anti-N-Methyl-d-Aspartate Receptor Encephalitis: A Review with Pooled Analysis and Critical Care Emphasis

PURPOSE

Anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis is being recognized with increasing frequency among children. Given the paucity of evidence to guide the critical care management of these complex patients, we provide a comprehensive review of the literature with pooled analysis of published case reports and case series.

METHODS

We performed a comprehensive literature search using PubMed, Scopus, EMBASE, and Web of Science for relevant published studies. The literature search was conducted using the terms NMDA, anti-NMDA, Anti-N-methyl-d-aspartate, pediatric encephalitis, and anti-NMDAR and included articles published between 2005 and May 1, 2016.

RESULTS

Forty-eight references met inclusion criteria accounting for 373 cases. For first-line treatments, 335 (89.8%) received high-dose corticosteroids, 296 received intravenous immunoglobulin (79.3%), and 116 (31%) received therapeutic plasma exchange. In these, 187 children (50.1%) had a full recovery with only minor deficits, 174 patients (46.7%) had partial recovery with major deficits, and 12 children died. In addition, 14 patients were reported to require mechanical ventilation.

CONCLUSION

Anti-NMDA encephalitis is a formidable disease with great variation in clinical presentation and response to treatment. With early recognition of this second most common cause of pediatric encephalitis, a multidisciplinary approach by physicians may provide earlier access to first- and second-line therapies. Future studies are needed to examine the efficacy of these current therapeutic strategies on long-term morbidity.

Anti-N-Methyl-D-Aspartate Receptor Encephalitis in Children and Adolescents

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is an autoimmune disease that is becoming increasingly recognized in the pediatric population. It may be the most common cause of treatable autoimmune encephalitis. The majority of cases of anti-NMDAR encephalitis are idiopathic in etiology, but a significant minority can be attributed to a paraneoplastic origin. Children with anti-NMDAR encephalitis initially present with a prodrome of neuropsychiatric symptoms, often with orofacial dyskinesias followed by progressively worsening seizures, agitation, and spasticity, which may result in severe neurologic deficits and even death. Definitive diagnosis requires detection of NMDAR antibodies in the cerebrospinal fluid. Optimal outcomes are associated with prompt removal of the tumor in paraneoplastic cases, as well as aggressive immunosuppressive therapy. Early detection is essential for increasing the chances for a good outcome. Close follow-up is required to screen for relapse and later onset tumor presentation. The nurse practitioner plays a major role in the research, screening, diagnosis, treatment, follow-up, and rehabilitation of a child or adolescent with anti-NMDAR encephalitis.

Anti N-methyl-D-aspartate receptor encephalitis: a game-changer?

INTRODUCTION

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is an inflammatory disorder of the brain that has garnered significant interest within the medical and lay communities. There is a need for formal guidelines to assist physicians in identifying patients who should undergo testing for NMDAR encephalitis, recognizing the high potential for this potentially treatable disease to mimic more common disorders, and consequently remain undiagnosed.

AREAS COVERED

This review highlights the impact of the discovery of NMDAR encephalitis on the fields of neurology and psychiatry, and discusses the steps that are necessary to improve recognition and treatment of NMDAR encephalitis. Expert commentary: While much progress has been made in our understanding of NMDAR encephalitis, much work remains to be done to delineate the underlying disease mechanisms and their relevance to brain function.
