Frequent EEG arousals during sleep are often associated with disruptions in the sleep cycle, leading to fragmented sleep architecture. This fragmentation can result in excessive daytime sleepiness, as the individual does not achieve the restorative stages of sleep necessary for effective functioning during waking hours. When arousals occur frequently, they prevent the sleeper from maintaining deep sleep, which is crucial for physical and mental restoration.

In contrast, improved sleep quality is characterized by fewer interruptions, allowing for longer periods of deep sleep and REM sleep, which are essential for feeling rested. Deep sleep stages are associated with fewer arousals, not frequent ones, indicating that option B is the most directly related to the symptom being assessed. Stable sleep patterns imply consistency and a lack of disturbances, which also does not align with the idea of frequent arousals. Therefore, the association between frequent EEG arousals and excessive daytime sleepiness underscores the impact of sleep disruptions on overall sleep quality and daytime alertness.
