RESUMO
Neuromyelitis optica spectrum disease (NMOSD) is a rare autoimmune disorder of the central nervous system characterized by optic neuritis, myelitis, or brain lesions. Its symptoms overlap with those of multiple sclerosis (MS), making a diagnosis of NMOSD challenging. Here, we report a rare case of NMOSD-induced complete spinal cord injury following COVID-19 vaccination. A 52-year-old female patient developed NMOSD-induced complete spinal cord injury after receiving their third dose of the Pfizer-BioNTech COVID-19 vaccine (BNT162b2). Despite the initial diagnosis of complete spinal cord injury, the patient underwent intensive treatment, including rituximab therapy and rehabilitation. As a result, she made a full recovery and transitioned from the ASIA Impairment Scale(AIS)-A to AIS-E. The remarkable neurological recovery from complete spinal cord injury to functional independence highlights the efficacy of a comprehensive treatment approach. In addition, this case emphasizes the need to recognize NMOSD as a potential adverse outcome of COVID-19 vaccination and emphasizes the importance of early diagnosis, timely intervention, and thorough rehabilitation for optimizing patient results. Further case reports and studies are needed to investigate the association between COVID-19 vaccination and the occurrence of NMOSD.
RESUMO
Patients with brain injury often experience accompanying disabilities that can make it challenging for them to use tools or perform complex tests. Therefore, Korean Mini-Mental State Examination (K-MMSE) is widely used in clinical practice as an alternative to the computerized neurocognitive test (CNT) or Wechsler Adult Intelligence Scale tests to assess cognitive function in these individuals. This study aimed to investigate the correlation between the K-MMSE and CNT in brain injury patients to evaluate the and clinical usefulness of K-MMSE. A total of 120 patients were assessed using both tests, and a significant correlation was observed between the total scores of K-MMSE and CNT. The orientation component of K-MMSE was significantly correlated with CNT components, indicating that individuals who perform well on orientation tasks are likely to have better cognitive abilities overall. While K-MMSE has limitations in evaluating specific cognitive domains, it is a useful tool in clinical practice for evaluating cognitive impairment, especially in patients who have difficulty using more complex cognitive tests.
