Alzheimer’s Disease (AD) is a neurodegenerative disease that is can be defined by amyloid beta (Aβ) plaques, neurofibrillary tangles, and neuronal death. AD patients have characteristically fragmented sleep, with frequent nighttime awakenings and daytime naps. Decreased clearance of Aβ from disrupted sleep may be a contributing factor in the progression of AD. This study investigated how sleep fragmentation effected the progression of AD in 3xTgAD mice. Results showed that sleep fragmented mice had significantly more Aβ build-up in the hippocampus and thus greater progression of AD when compared to control mice. Improving sleep may be one way to reduce the …
