Involvement of central nervous system occasionally occurs as a form of aseptic meningitis in Kikuchi-Fujimoto disease (KFD). However, acute cerebellar symptoms are very rare in KFD. We describe a 42 year-old woman presenting kinetic tremor and gait ataxia preceding cervical lymphadenopathy. The diagnosis of KFD was made based on pathology. Lymphocyte-dominant pleocytosis was observed in cerebrospinal fluid. Brain and spinal magnetic resonance imaging showed no structural abnormalities. Acute cerebellar symptoms and cervical lymphadenopathy disappeared spontaneously within 2 months. This case of KFD involved unusual acute cerebellar symptoms. Selective involvement of the cerebellar system by viral or immunologic response may be attributed to acute cerebellar symptoms in KFD.

Autoimmune cerebellar ataxia (ACA) is a cerebellar syndrome induced by autoimmune reactions and its onset is induced by malignant tumors, prodromic infection, and gluten allergy. Its clinical symptoms include gait disorder, limb ataxia, dysarthria, and dysphagia. According to , the diagnosis of ACA is based on the following points: 1.

Objective: To investigate changes of brain functional activity in patients with acute unilateral vestibulopathy (AUVP) using functional magnetic resonance imaging (fMRI).

Methods: We studied 32 AUVP patients and 30 healthy controls (HC) who received resting-state fMRI scanning. Methods of voxel-based amplitude of low-frequency fluctuation (ALFF) and seed-based functional connectivity (FC) were adopted to compare the difference in brain function between the two groups.

Acute cerebellar ataxia is a clinical syndrome that involves loss of balance and coordination, typically within less than 72 hours. It usually presents in children and rarely affect adults. A woman in her early 20s presented with acute onset dizziness, vertigo, truncal ataxia and dysarthria 2 weeks following an acute viral illness.

The ultrastructural organization of the nuclei of the tegmental region in juvenile chum salmon () was examined using transmission electron microscopy (TEM). The dorsal tegmental nuclei (DTN), the nucleus of (NFLM), and the nucleus of the oculomotor nerve (NIII) were studied. The ultrastructural examination provided detailed ultrastructural characteristics of neurons forming the tegmental nuclei and showed neuro-glial relationships in them.

COVID-19 disease, caused by the SARS-CoV-2 virus, has significantly altered modern society and lifestyles. We investigated its impact on brain glucose metabolism by meta-analyzing existing studies that utilized 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) scans of the brain. We conducted a systematic search of MEDLINE and EMBASE databases from inception to August 2024 for English-language publications using the keywords "positron emission tomography", and "COVID-19".
