How does modafinil help reduce daytime sleepiness in narcolepsy?

Modafinil is a medication used to help people with narcolepsy stay awake during the day. Narcolepsy is a condition that makes people feel very sleepy during the day, even if they had a good night's sleep. Modafinil works by affecting certain chemicals in the brain called neurotransmitters. These chemicals help control when we feel awake and when we feel sleepy.

How Modafinil Works

1. Brain Chemicals: Modafinil changes the way some brain chemicals work. These chemicals, like dopamine and norepinephrine, help keep us awake and alert.
2. Wakefulness: By affecting these chemicals, modafinil helps people with narcolepsy feel more awake during the day.

Why It Helps

• Less Sleepiness: Studies show that people who take modafinil feel less sleepy during the day.
• Better Functioning: It can help people with narcolepsy do better at school, work, and in other activities because they are not as sleepy.

Modafinil is an important medicine for people with narcolepsy because it helps them stay awake and be more active during the day.
