During the night, nightmares can wake a person up feeling frightened, making it difficult to fall back asleep. Frequent bad dreams can negatively affect sleep quality, mood, and thinking.

Using these findings, doctors can find new ways to diagnose dementia early, slow its progression, and even prevent it in some cases.
