Investigating the frequency of neural autoantibodies in refractory focal epilepsy.
Seizure
January 2025
Neurology department, Royal Brisbane and Women's Hospital, Brisbane, Australia.
Objectives: There have been conflicting reports about the frequency of neural autoantibodies in epilepsy cohorts, which is confounded by the lack of clear distinction of epilepsy from acute symptomatic seizures due to encephalitis. The aim of this study was to determine the frequency of neural autoantibodies in a well characterised population of refractory focal epilepsy of known and unknown cause.
Methods: Cases were recruited from epilepsy outpatient clinics at the Princess Alexandra, Mater, Royal Brisbane and Women's and Cairns Base Hospitals from 2021 - 2023.
Sex Differences in Natural History and Health Outcomes Among Individuals With Tic Disorders.
Neurology
February 2025
Department of Neurology, Massachusetts General Hospital, Harvard Medical School, Boston, MA.
Objectives: To analyze sex differences in outcomes in Tourette syndrome (TS) and Persistent Motor or Vocal tic disorders (PMVT) in the Tourette Association of America International Consortium for Genetics (TAAICG) dataset.
Methods: The relationship between sex and clinical measures was explored in 2,403 participants (N = 2,109 with TS; N = 294 with PMVT) from the TAAICG dataset using generalized estimating equation regression models, and adjusted for age and family relationships.
Results: Female (vs male) participants with TS (25.
The TRP Channels Serving as Chemical-to-Electrical Signal Converter.

Department of Physiology and Membrane Biology, University of California, Davis, School of Medicine, Davis CA, 95616, USA.
Biology uses many signaling mechanisms. Among them, calcium and membrane potential are two prominent mediators for cellular signaling. TRPM4 and TRPM5, two calcium-activated monovalent cation-conducting ion channels, offer a direct linkage between these two signals.

Department of Neurology and Neurosurgery, Montreal Neurological Institute, McGill University, Montreal, Canada.
Anatomical studies have revealed a prominent role for feedback projections in the primate visual cortex. Theoretical models suggest that these projections support important brain functions, like attention, prediction, and learning. However, these models make different predictions about the relationship between feedback connectivity and neuronal stimulus selectivity.

Alzheimer's disease (AD) is the most prevalent neurodegenerative disorder. Antiamyloid antibody treatments modestly slow disease progression in mild dementia due to AD. Emerging evidence shows that homeostatic dysregulation of the brain immune system, especially that orchestrated by microglia, plays an important role in disease onset and progression.
