Autoimmune encephalitis with coexisting antibodies to GABABR, GAD65, SOX1 and Ma2
Li P, Yang T, Gu Y, Zhou J and Wang Z
Autoimmune encephalitis (AE) is a disease caused by an abnormal reaction between the body's autoimmunity and the central nervous system, in which the abnormal immune response targets antigenic components within or on the surface of neuronal cells. The main manifestations are mental and behavioural changes, cognitive impairment, impaired consciousness, seizures, movement disorders, etc. Most cell surface antibodies respond well to immunotherapy, intracellular antibodies, on the other hand, are usually associated with more tumours and are relatively difficult to treat with a poor prognosis. In recent years, autoimmune encephalitis that is positive for multiple anti-neuronal antibodies has been gradually recognized in the clinic, with complex and varied clinical manifestations, especially in combination with malignant tumours, which have worse treatment and prognosis. Current clinical studies on the coexistence of multiple anti-neuronal antibodies in patients with AE are mainly disseminated case reports. Patients with AE in which four anti-neuronal antibodies coexist are even rarer.

Highly prevalent geriatric medications and their effect on β-amyloid fibril formation
Zaman Z, Islam R, Koganti B, Falki V, Osentoski T, Graham S and Sharoar MG
The unprecedented increase in the older population and ever-increasing incidence of dementia are leading to a "silver tsunami" in upcoming decades. To combat multimorbidity and maintain daily activities, elderly people face a high prevalence of polypharmacy. However, how these medications affect dementia-related pathology, such as Alzheimer's β-amyloid (Aβ) fibrils formation, remains unknown. In the present study, we aimed to analyze the medication profiles of Alzheimer's disease (AD; n = 124), mild cognitive impairment (MCI; n = 114), and non-demented (ND; n = 228) patients to identify highly prevalent drugs and to determine the effects of those drugs on Aβ fibrils formation.

Cognitive impact and brain structural changes in long COVID patients: a cross-sectional MRI study two years post infection in a cohort from Argentina
Cataldo SA, Micciulli A, Margulis L, Cibeyra M, Defeo S, Horovitz SG, Martino A, Melano R, Mena M, Parisi F, Santoro D, Sarmiento F and Belzunce MA
Long COVID is a condition characterised by persistent symptoms after a SARS-CoV-2 infection, with neurological manifestations being particularly frequent. Existing research suggests that long COVID patients not only report cognitive symptoms but also exhibit measurable cognitive impairment. Neuroimaging studies have identified structural alterations in brain regions linked to cognitive functions. However, most of these studies have focused on patients within months of their initial infection. This study aims to explore the longer-term cognitive effects and brain structural changes in long COVID patients, approximately two years post-infection, in a cohort from San Martín, Buenos Aires, Argentina.
Relationship between reticulospinal system sensitization and proprioceptive pathways in the development of dynamic spasticity (ReProDS) post-spinal cord injury: protocol for a prospective, observational cohort study
Wang J, Fan L, Sun J, Chen J, Wang Y, OuYang Z, Yuan Z, Sun C, Jin L and Wang Y
Dynamic spasticity (DS) is a common complication post-spinal cord injury (SCI), marked by intermittent increases in muscle tone during postural transitions or movement. Despite its prevalence, high-quality research on DS incidence, risk factors, and underlying mechanisms in SCI patients remains limited. With the growing application of spinal cord stimulation (SCS) for spasticity control, the role of proprioception in DS development has garnered attention. Additionally, advances in diffusion tensor imaging (DTI) allow for the analysis of the reticulospinal tract's (RST) role in postural control among SCI patients. However, the impact of microstructural changes in RST and proprioception on DS following SCI remains unclear.

Comparing cognitive impairment using MACFIMS in patients with multiple sclerosis and healthy controls: a systematic review and meta-analysis
Nasirzadeh A, Mohammadi M, Bafrani MA, Mohammadi A and Bakhtiari-Dovvombaygi H
Multiple sclerosis (MS) is a chronic autoimmune disorder affecting the central nervous system, leading to a range of symptoms that impact physical, psychiatric, and cognitive functions. Cognitive dysfunction is prevalent among patients with MS (pwMS), affecting at least 65% of patients, and includes deficits in processing speed, attention, learning, memory, and executive function. Despite the significant impact on daily life, cognitive impairment in MS patients is often underrecognized in clinical settings.

Electroencephalography based delirium screening in acute supratentorial stroke
Hermann G, Baumgarte F, Welzel J, Nydahl P, Kuhlenbäumer G and Margraf NG
Up to 25% of patients suffering from an acute stroke are diagnosed with delirium during the hospital stay, with older age increasing the risk. Generalized slowing in the electroencephalogram (EEG) supports the diagnosis of delirium. We examined the potential of single-channel EEG (DeltaScan) as an easy-to-use device on intensive care units for detecting delirium. Our aim was to investigate characteristics of bihemispheric EEG recordings and single-channel EEG in patients suffering from strokes with and without delirium and to analyze the diagnostic accuracy of EEG-based diagnoses.

Abnormalities along the cortico-medullary junction on brain MRI caused by 1,2-dichloroethane-induced toxic encephalopathy
Cai D, Kuang L, Hu F and Shen Y
1,2-dichloroethane (DCE) induced toxic encephalopathy, a rare toxic disease of the central nervous system, is mainly reported in developing countries. Although clinicians have got some understanding about the clinical and neuroimaging features of 1,2-DCE-induced toxic encephalopathy, abnormality along the cortico-medullary junction on diffusion-weighted image (DWI) mimicking neuronal intranuclear inclusion disease (NIID) has not yet been described in this entity.
Case report: orthostatic hypotension as the first presentation of progressive encephalomyelitis with rigidity and myoclonus (PERM) with multiple autoimmune antibodies
Song J, Hu S, Chen L, Lan C and Lu P
Stiff person syndrome (SPS) is a rare disease characterized by axial and lower-extremity muscle rigidity, muscle spasm, and pain. Progressive encephalomyelitis with rigidity and myoclonus (PERM) is a variant of SPS. This case is particularly notable for its uncommon initial symptom: orthostatic hypotension, coupled with the presence of multiple antibodies. Such a presentation is a rarity in the context of PERM, thus providing a fresh and unique angle for both diagnosis and treatment.
A case report of an individual with Creutzfeldt-Jakob disease characterized by prolonged isolated thalamic lesions and rare MM2-cortical-type pathology
Kunii M, Kishida H, Tada M, Okamoto M, Asano K, Nakamura H, Takahashi K, Hashiguchi S, Kubota S, Okubo M, Takeuchi H, Ueda N, Satoh K, Kitamoto T, Doi H and Tanaka F
Diffusion-weighted magnetic resonance imaging (DWI) is essential for diagnosing Creutzfeldt-Jakob disease (CJD). Thalamic lesions are rarely detected by DWI in sporadic CJD (sCJD) cases with methionine homozygosity at polymorphic codon 129 (129MM) of the prion protein (PrP) gene. Here, we describe an unusual sCJD case, characterized by prolonged isolated thalamic diffusion hyperintensities and atypical brain pathology, in combination with the 129MM genotype.
