Neurofibriilary tangle-predominant dementia

Abstract

Neurofibrillary tangle-predominant dementia(NFTPD)is one type of late-onset dementia, with memory disorders as the main clinical manifestation.The pathological feature is the presence of a large number of neurofibrillary tangle(NFT)in the hippocampus with no or little amyloid deposition in the brain.In recent years, primary age-related tauopathy(PART)has been proposed as a new pathological term, which means that NFT appears in the medial temporal lobe with aging, but no amyloid deposits, and NFTPD is one type of dementia associated with the progression of PART. Key words: Neurofibrillary tangle; Dementia; Nerve degeneration
