When students do not get the adequate amount of sleep, they become more exposed to the consequences of sleep deprivation. One of the effects of sleep deprivation has to do with the brain. As students become increasingly sleep deprived, their brains begin to shrink. Cells begin to decline, thus making us more susceptible to the negative effects of brain damage. When the brain is damaged, students can experience seizures that could result in death. They may also have Alzheimer's disease due to degeneration of the brain.
