The escalating prevalence of Alzheimer's disease (AD) among aging populations underscores the critical need for early detection and intervention to mitigate its effects. Sleep disturbances, particularly prevalent in individuals with mild cognitive impairment (MCI) and AD, suggest a significant link between sleep quality and neurodegenerative diseases. Indeed, neuroscientific evidence emphasizes abnormal brain rhythms during sleep and disruptions in specific brain chemicals as fundamental components of cognitive decline and the onset of AD. Importantly, these abnormalities may manifest before noticeable symptoms, indicating their potential as early indicators of neurodegeneration. Electroencephalogram (EEG) recording during sleep is currently a widely adopted technique for extracting such information.
