History of Narcolepsy
Awareness, timely diagnosis, and individualized care are essential to improving the lives of people living with narcolepsy.
Narcolepsy is a complex neurological condition that has puzzled researchers for over a
century. From its early classification in the 19th century to recent advances in genetics and immunology, the journey of understanding narcolepsy reflects the broader evolution of neuroscience and sleep medicine. This timeline offers a look at key milestones in the recognition, study, and treatment of narcolepsy.
