Which of the following is an example of Pathological sleepiness?

Consistently struggling to stay awake during daytime activities is an example of pathological sleepiness because it indicates a chronic problem with excessive sleepiness that interferes with normal functioning. This condition can be associated with various sleep disorders, such as narcolepsy or sleep apnea, and suggests that the individual is not getting adequate restorative sleep at night, leading to difficulties in maintaining alertness during the day. Pathological sleepiness goes beyond normal tiredness and indicates a potential underlying health issue that may require assessment and management by a healthcare professional.

Feeling groggy after sleep could simply be a result of poor sleep quality or sleep inertia, while feeling refreshed after a night's sleep typically indicates that sleep was adequate and restorative. Occasional yawning during the day may not be indicative of a significant problem, as it can occur in response to boredom or brief moments of drowsiness without suggesting chronic sleep issues.
