ABSTRACT

Sleep problems and Alzheimer’s Disease (AD) are two disorders often seen together. Age-related structural and physiological changes in certain parts of the brain lead to changes in sleep patterns. Conditions such as AD also affect these areas of the brain, thus changing the sleep-wake cycle. Sleep disorders likewise adversely affect the course of the disease. Sleep quality is important for the proper functioning of the memory. Impaired sleep is also associated with problems in some areas of the brain that play a key role in learning and memory functions. Changes in the brain seen in aging and AD disrupt sleep and memory processes, leading increased cognitive impairment. In addition to synthetic drugs, treatment with plants has also become a preferred factor in the treatment. Curcuminoids, which are in the structure of diarylheptanoid, are the main components of turmeric. Curcumin has multiple applications in treatment regimes of various diseases such as cardiovascular diseases, obesity, cancer, inflammatory diseases, and aging. Besides these applications and activities, curcumin has been reported to be effective in many neurodegenerative diseases. There are plenty of studies show-ing that curcumin can lead significant improvements in the pathological process of AD. Despite many important positive effects, the therapeutic limitation of curcumin is its low solubility and bioavailabil-ity. New approaches are needed to solve this problem and many studies have focused different types of advanced nanoformulations. This review summarizes the available scientific data, as reported by the most recent studies describing the treatment of Alzheimer’s Disease and sleep deprivation-related consequences.
