How daily and internal body clocks affect cell metabolism and brain diseases

The circadian clock regulates various biological functions, including hormone levels and cognitive function.

• The circadian clock is involved in optimizing biological functions for specific times of the day.
• Sleep-wake cycles are the most visible outputs of the circadian clock.
• Disruption of circadian rhythms and sleep may be linked to neurodegenerative diseases.
• There is evidence suggesting that the circadian clock may influence metabolic pathways.
• Connections between the circadian clock, metabolism, and neurodegenerative disease are proposed.
