What is the prevalence of Idiopathic Hypersomnia?

Idiopathic Hypersomnia is a neurological sleep disorder characterized by excessive daytime sleepiness and prolonged sleep duration. It is a relatively rare condition, and its prevalence is not well-established due to underdiagnosis and misdiagnosis.

However, studies suggest that the prevalence of Idiopathic Hypersomnia is estimated to be around 0.02% to 0.05% of the general population. This means that out of every 10,000 individuals, approximately 2 to 5 people may be affected by this disorder.

Idiopathic Hypersomnia typically begins during adolescence or early adulthood and can persist throughout a person's life. It is often misdiagnosed as other sleep disorders, such as narcolepsy or chronic fatigue syndrome, which further complicates determining its true prevalence.

While the exact cause of Idiopathic Hypersomnia is unknown, it is believed to involve abnormalities in the central nervous system. The symptoms can significantly impact an individual's daily functioning, leading to difficulties in work, education, and social interactions.

Early recognition and proper diagnosis are crucial for managing Idiopathic Hypersomnia. Treatment options include stimulant medications, lifestyle modifications, and scheduled napping to help alleviate excessive sleepiness and improve quality of life.
