All You Need to Know About Narcolepsy. br Narcolepsy is a rare, chronic neurological condition that disrupts sleep, affecting around 1 in 2,000 people. Symptoms typically begin between ages 7 and 25 but often go unrecognized for years. It can lead to temporary muscle control loss called cataplexy and low brain protein hypocretin, called Type 1 narcolepsy. Without cataplexy and normal hypocretin levels, it’s Type 2. Narcolepsy isn’t deadly but can lead to accidents and difficulties in daily life. Managing it can help improve quality of life.
