How are MSLT scores classified based on specific minute intervals?

The classification of Multiple Sleep Latency Test (MSLT) scores is based on the time it takes for an individual to fall asleep in a quiet environment. MSLT is primarily used to assess excessive daytime sleepiness and can provide valuable insights into the presence of sleep disorders, such as narcolepsy or idiopathic hypersomnia.

In this context, the scoring system typically categorizes sleep latency as follows:

• A sleep latency of 0–5 minutes indicates Severe sleepiness, suggesting that the person falls asleep almost immediately, which may signal a significant issue with controlling daytime sleepiness.

• A latency of 6-10 minutes is classified as Troublesome, reflecting some degree of sleepiness that may warrant clinical attention but is not as alarming as severe sleepiness.

• A score of 11-15 minutes is termed Manageable, indicating that the individual has some ability to remain awake, and may not have significant daytime sleepiness issues.

• A latency of 16-20 minutes is considered Excellent, suggesting that the person has a good level of alertness and a lower likelihood of experiencing excessive sleepiness during the day.

Thus, the correct classification corresponds with the timeframe brackets assigned to severity levels on the MSLT, aligning with the commonly
