This article published in 2025 by Huw Green and Jon Stone,  focuses on health anxiety within neurological settings . It  explains health anxiety as a distinct, treatable psychological disorder  characterized by excessive worry about illness and compulsive "safety behaviors" like seeking reassurance. The authors  distinguish health anxiety from normal health concerns and functional neurol...

Laser interstitial thermal therapy (LITT) is an increasingly standard surgical tool for ablating epileptic foci, and the Laser Ablation of Abnormal Neurological Tissue Using Robotic NeuroBlate System (LAANTERN) registry, representing the largest prospective multicenter cohort, aimed to describe seizure outcomes, procedural outcomes, and safety data for LITT in mesial temporal lobe epilepsy (MTLE)....

This paper investigates the  heterogeneity of autoantibodies  in patients with myasthenia gravis (MG), focusing on their  diverse pathogenic properties  and  temporal fluctuations . The researchers utilized advanced cell-based assays to analyze serum samples, revealing that different  immunoglobulin isotypes (IgG, IgM, IgA)  and  IgG subclasses  contribute to the disease through varying mechanisms...

Valosin-Containing Protein (VCP) myopathy , also known as Multisystem Proteinopathy (MSP1) or Inclusion Body Myopathy associated with Paget disease of bone and Frontotemporal Dementia (IBMPFD), is a complex, progressive, autosomal dominant adult-onset disorder caused by mutations in the VCP gene. The VCP protein, also called p97, is a highly conserved ATPase crucial for maintaining cellular protei...

This comprehensive report from the  American Academy of Neurology , in collaboration with the  American Congress of Rehabilitation Medicine  and the  National Institute on Disability, Independent Living, and Rehabilitation Research , provides updated guidelines for managing  prolonged disorders of consciousness (DoC)  in both adults and children. It outlines  diagnostic accuracy improvements , inc...

This article presents a  multicenter cohort study  examining the  influence of comorbidities on outcomes and infectious complications  in patients with  autoimmune encephalitis (AE) . The study analyzed  data from 308 adult patients  with common AE variants, identifying various  preexisting conditions (PECs)  and  secondary diagnoses . Key findings indicate that  psychiatric PECs are an independen...
