The aim of this study is to detect the features of sleep disorder via polysomnography (PSG) based on Chinese pedigree of frontotemporal dementia with parkinsonism linked to chromosome 17 (FTDP-17).
Sleep disorders have previously been connected with the neurodegenerative pathology of Alzheimer's disease (AD) due to the aggregation of β-amyloid(Aβ)peptides and tau proteinsinduced by sleep deprivation (SD).
