Objective: To retrospectively investigate the clinical data, radiological characteristics, treatment, and outcome of patients with parenchymal neuro-Behcet's disease (P-NBD) with particular emphasis on dizziness. Methods: This was a cross-sectional study of clinical data from 25 patients with a confirmed diagnosis of P-NBD who were admitted to the Department of Neurology of the First Medical Center of Chinese People's Liberation Army General Hospital between 2010 and 2022. The median age of the population was 37 years (range: 17-85 years). Clinical data were retrospectively analyzed, including gender, age of onset, disease duration, clinical manifestations, serum immune indicators, cerebrospinal fluid (CSF) routine biochemical and cytokine levels, cranial and spinal magnetic resonance imaging (MRI) findings, treatment, and outcome. Results: The majority of patients were male (16 cases; 64.0%), the mean age of onset was (28±14) (range: 4-58 years), and the disease course was acute or subacute. Fever was the most common clinical presentation, and the complaint of dizziness was not uncommon (8/25 patients). Analysis of serum immune indices, including complement (C3 and C4), erythrocyte sedimentation rate, interleukin-1 (IL-1), IL-6, IL-8 and tumor necrotic factor-alpha were abnormal in 80.0% of patients (20/25). Most of the 16/25 patients who underwent lumbar puncture tests had normal intracranial pressure and increased CSF white cell count and protein [median values were 44 (15-380) ×10⁶/L and 0.73 (0.49-2.81) g/L, respectively]. Of the five patients who underwent CSF cytokine tests, four patients had abnormal results; of these, an elevated level of IL-6 was most common, followed by IL-1 and IL-8. The most common site of involvement in cranial MRI was the brainstem and basal ganglia (60.0% respectively), followed by white matter (48.0%) and the cortex (44.0%). Nine cases (36.0%) showed lesions with enhancement and six cases (24.0%) showed mass-like lesions. Three patients (12.0%) patients had lesions in the spinal cord, most frequently in the thoracic cord. All patients received immunological intervention therapy; during follow up, the majority had a favorable outcome. Conclusions: P-NBD is an autoimmune disease with multiple system involvement and diverse clinical manifestations. The symptom of dizziness is not uncommon and can be easily ignored. Early treatment with immunotherapy is important and can improve the outcome of these patients.

Migraine is the most common disabling primary headache with a significant socioeconomic burden. At present, some emerging drugs for migraine preventive treatment are under investigation internationally, which significantly promote the progress of migraine treatment. However, only few of this trial for migraine treatment are explored in China. In order to promote and standardize controlled clinical trials of migraine preventive therapy in China, and to provide methodological guidance for the design, implementation and evaluation of clinical trials, the Headache Collaborators of Chinese Society of Neurology formulated this consensus.

This is a case of a 7-year-old Filipino female who presented with undulating movements of the abdomen that occur only while awake, following the initiation of treatment for clinically diagnosed pulmonary tuberculosis. Systemic physical examination was normal. The neurological examination was also unremarkable. The 2-hr video EEG showed no electroencephalographic changes or ictal pattern correlating with the abdominal dyskinesia, highly suggesting a movement disorder. Craniospinal Magnetic Resonance Imaging (MRI) with Gadolinium showed typical results. The patient responded to the trial of carbamazepine after three weeks of treatment with complete resolution of abdominal dyskinesia.

Introduction. The COVID-19 pandemic presented an extraordinary challenge to the operations of private hospitals involved in neurological residency training. Numerous adaptations were made to restructure the hospital, including the special units and diagnostic centers. Teaching and training activities were swiftly transitioned to online platforms and research activities were streamlined. Manpower allocation into teams with active duties followed by mandatory quarantine periods became the norm.

Objective. To evaluate the effect of the COVID-19 pandemic on the neurology training program by comparing two periods: pre-pandemic and pandemic periods.

Methods. We reviewed the changes implemented by the hospital in response to the pandemic. We also looked into our residency training program pre-pandemic and the subsequent changes instituted to adapt to the pandemic.

Results. Due to the community quarantine imposed by the government, there was a drastic drop by as much as 70.5% in the out-patient census, 38.4% in the in-patient census, and 46.9% in neurodiagnostic (electroencephalography and electrodiagnostic medicine). The residents were reorganized into three teams of 4 residents, further divided into COVID and non-COVID rotations for 5 days straight duty. Consultants were also stratified into high-risk (on-call for emergency referrals in a work-from-home scheme) and non-high-risk (COVID patient rounds). Teleconsultation was likewise utilized. Academic activities were shifted to blended online learning.

Conclusion. There was a need to reorganize resident staffing brought about by the hospital changes as well, to ensure safety during the pandemic. The pandemic has forced us to shift to alternative methods of teaching and examination, such as teleneurology. Regular assessments and adjustments to the training program will need to be done to adapt to an evolving situation.

Background and objective : Neurodevelopmental disabilities in adolescents have signifi cant effects on medical and social function. One of these challenges is their transition into adult care. Parental involvement is critical because these young adults may have more diffi culties in making informed decisions independently. Thus, the transition process involves not only the direct health care needs of the young adult, but the needs and concerns of the parents or carers who are instrumental in guiding that process. This study aims to explore the expectations and experiences of family carers of youths with chronic neurodevelopmental disorders who have undergone or are about to undergo transition into adult healthcare in a Filipino-based health care system. Methods: A descriptive phenomenology was used to gain an in-depth understanding of parents’ perceptions and experiences of their youths’ transition process from a pediatric to an adult health care setting. The results were analyzed manually using Colaizzi’s method, which involves integrating both the destructured and restructured analysis principles of phenomenology. Purposive sampling was used to interview 13 family carers of 13 youths with various neurodevelopmental disorders using a semi-structured interview questionnaire. Results : Despite the lack of information on the transition process, our study found that carers did not have a strong inclination to resist the transition event. Most of the carers treat the health care provider as a major decision maker in determining the timing and manner of transition, adopting a “doctor knows best” attitude. Several other hindrances and facilitators to successful transition were also identifi ed and are similar to the current literature. Conclusion This study provides a greater understanding of carers’ perceptions and experiences of transition care for youths with neurodevelopmental disorders in the local setting. They exhibited trust and confi dence in the medical profession as a whole, and had a “doctor knows best” attitude that may enable successful transitioning.

PURPOSE: The brainstem plays an important role in the control of micturition, and brainstem strokes are known to present with micturition dysfunction. Micturition dysfunction in cases of lateral medullary infarction (LMI) is uncommon, but often manifests as urinary retention. In this study, we investigated the neuro-anatomical correlates of urinary retention in patients with LMI. METHODS: This was a hospital-based retrospective study conducted in the neurology unit of a quaternary-level teaching hospital. Inpatient records from January 2008 to May 2018 were searched using a computerized database. Cases of isolated LMI were identified and those with micturition dysfunction were reviewed. MRI brain images of all patients were viewed, and individual lesions were mapped onto the Montreal Neurological Institute (MNI) space manually using MRIcron. Nonparametric mapping toolbox software was used for voxel-based lesion-symptom analysis. The Liebermeister test was used for statistical analysis, and the resultant statistical map was displayed on the MNI template using MRIcron. RESULTS: During the study period, 31 patients with isolated LMI were identified. Their mean age was 48 years and 28 (90%) were male. Six of these patients (19%) developed micturition dysfunction. All 6 patients had urinary retention and 1 patient each had urge incontinence and overflow incontinence. In patients with LMI, the lateral tegmentum of the medulla showed a significant association with urinary retention. CONCLUSIONS: In patients with isolated LMI, we postulate that disruption of the descending pathway from the pontine micturition centre to the sacral spinal cord at the level of the lateral tegmentum results in urinary retention.

BACKGROUND AND PURPOSE: To investigate whether appointing a full-time neurointensivist to manage a closed-type neurological intensive care unit (NRICU) improves the quality of critical care and patient outcomes. METHODS: This study included patients admitted to the NRICU at a university hospital in Seoul, Korea. Two time periods were defined according to the presence of a neurointensivist in the preexisting open-type NRICU: the before and after periods. Hospital medical records were queried and compared between these two time periods, as were the biannual satisfaction survey results for the families of patients. RESULTS: Of the 15,210 patients in the neurology department, 2,199 were admitted to the NRICU (n=995 and 1,204 during the before and after periods, respectively; p<0.001). The length of stay was shorter during the after than during the before period in both the NRICU (3 vs. 4 days; p<0.001) and the hospital overall (12.5 vs. 14.0 days; p<0.001). Neurological consultations (2,070 vs. 3,097; p<0.001) and intrahospital transfers from general intensive care units to the NRICU (21 vs. 40; p=0.111) increased from the before to after the period. The mean satisfaction scores of the families of the patients also increased, from 78.3 to 89.7. In a Cox proportional hazards model, appointing a neurointensivist did not result in a statistically significant change in 6-month mortality (hazard ratio, 0.82; 95% confidence interval, 0.652–1.031; p=0.089). CONCLUSIONS: Appointing a full-time neurointensivist to manage a closed-type NRICU had beneficial effects on quality indicators and patient outcomes.

BACKGROUND AND PURPOSE: Neurological involvement in Behçet's disease [neuro-Behçet's disease (NBD)] is uncommon, but it is worth investigating since it can cause substantial disability. However, difficulties exist in understanding the clinical features of NBD due to regional variations and the lack of studies utilizing well-established diagnostic criteria. We therefore analyzed the clinical features of patients with NBD based on the recent international consensus recommendation. METHODS: We retrospectively searched electronic databases for patients with Behçet's disease (BD) between 2000 and 2017, and reviewed their medical records. Based on the recent international consensus recommendation, patients with definite or probable NBD were included. RESULTS: Of 9,817 patients with the diagnosis code for BD, 1,682 (17.1%) visited the neurology clinic and 110 (1.1%) were classified as NBD. Ninety-eight patients exhibited parenchymal NBD and 12 exhibited nonparenchymal NBD. Their age at the onset of NBD was 37.6±10.6 years and the male-to-female ratio was 1.24:1. Brainstem syndrome (43.9%) was the most common condition in the 98 patients with parenchymal NBD, followed by multifocal (32.7%) and spinal cord (12.2%) syndromes. 72.4% exhibited acute NBD and 27.6% exhibited a progressive disease course. Frequent manifestations included pyramidal signs (52.0%), headache (45.9%), dysarthria (42.9%), and fever (31.6%). A frequent pattern in brain MRI was an upper brainstem lesion extending to the thalamus and basal ganglia. CONCLUSIONS: Approximately 1% of the patients with suspected BD exhibited NBD. Neurologists must understand the clinical characteristics of NBD in order to perform the differential diagnosis and management of these patients.

The nineteenth century neuroscience studied the instinct of animal to understand the human mind. In particular, it has been found that the inheritance of unconscious behavior like instinct is mediated through ganglion chains, such as the spinal cord or sympathetic nervous system, which control unconscious reflexes. At the same time, the theory of Inheritance of Acquired Characteristics (hereafter ‘IAC’) widely known as Lamarck's evolutionary theory provided the theoretical frame on the origin of instinct and the heredity of action that the parental generation's habits were converted into the nature of the offspring generation. Contrary to conventional knowledge, this theory was not originally invented by Lamarck, and Darwin also did not discard this theory even after discovering the theory of natural selection in 1838 and maintained it throughout his intellectual life. Above all, in the field of epigenetics, the theory of ‘IAC’ has gained attention as a reliable scientific theory today. Darwin discovered crucial errors in the late 1830s that the Lamarck version's theory of ‘IAC’ did not adequately account for the principle of the inheritance of unconscious behavior like instinct. Lamarck's theory regarded habits as conscious and willful acts and saw that those habits are transmitted through the brain to control conscious actions. Lamarck's theory could not account for the complex and elaborate instincts of invertebrate animals, such as brainless ants. Contrary to Lamarck's view, Darwin established the new theory of ‘IAC’ that could be combined with contemporary neurological theory, which explains the heredity of unconscious behavior. Based on the knowledge of neurology, Darwin was able to translate the ‘principle of habit’ into a neurological term called ‘principle of reflex’. This article focuses on how Darwin join the theory of ‘IAC’ with nineteenth century neuroscience and how the neurological knowledge from the nineteenth century contributed to Darwin's overcoming of Lamarck's ‘IAC’. The significance of this study is to elucidate Darwin's notion of ‘IAC’ theory rather than natural selection theory as a principle of heredity of behavior. The theory of ‘IAC’ was able to account for the rapid variation of instincts in a relatively short period of time, unlike natural selection, which operates slowly in geological time spans of tens of millions of years. The nineteenth century neurological theory also provided neurological principles for ‘plasticity of instinct,’ empirically supporting the fact that all nervous systems responsible for reflexes respond sensitively to very fine stimuli. However, researchers of neo-Darwinian tendencies, such as Richard Dawkins and evolutionary psychologists advocating the ‘selfish gene’ hypothesis, which today claim to be Darwin's descendants, are characterized by human nature embedded in biological information, such as the brain and genes, so that it cannot change at all. This study aims to contribute to reconstructing the evolutionary discourse by illuminating Darwin's insights into the “plasticity of nature” that instincts can change relatively easily even at the level of invertebrates such as earthworms.
