Abstract
Multiple sclerosis (MS) and Alzheimer's disease are neurodegenerative diseases with age-related disability accumulation. In MS, inflammation spans decades, whereas AD is characterized by Aβ plaques and neurofibrillary tangles (NFT). Few studies explore accumulation of amyloids in MS. We examined Aβ deposition and NFT density in temporal and frontal cortices from postmortem MS (n = 75) and control (n = 66) cases. Compared with controls, MS cases showed reduced Aβ, especially in those aged <65 years, and reduced NFT, notably in cases aged >65 years. Aβ deposition predicted greater NFT density both in MS cases and controls. MS-related factors may affect Aβ/NFT deposition and/or clearance, offering new therapeutic insights for both diseases.

期刊介绍：
Annals of Neurology publishes original articles with potential for high impact in understanding the pathogenesis, clinical and laboratory features, diagnosis, treatment, outcomes and science underlying diseases of the human nervous system. Articles should ideally be of broad interest to the academic neurological community rather than solely to subspecialists in a particular field. Studies involving experimental model system, including those in cell and organ cultures and animals, of direct translational relevance to the understanding of neurological disease are also encouraged.
