Summary:
- The article discusses a study that found people who experience excessive daytime sleepiness may be at a higher risk of developing a pre-dementia syndrome called mild cognitive impairment (MCI).
- MCI is a condition where individuals have cognitive decline that is more severe than normal age-related changes, but not severe enough to be considered dementia.
- The study suggests that addressing excessive daytime sleepiness may be an important step in preventing or delaying the onset of MCI and potentially dementia.
