A scoping review of the evidence on pharmacological and nonpharmacological interventions for idiopathic hypersomnia.

STUDY OBJECTIVES

Idiopathic hypersomnia (IH) is characterized by excessive sleepiness during the day, prolonged sleep at night, and difficulty waking up. The true prevalence of IH is uncertain. The provides criteria for diagnosing IH; however, the definition has evolved. Managing IH involves using pharmacologic and nonpharmacologic approaches, although the most effective strategies are still unclear. The objective of this scoping review was to identify the extent, range, and nature of the available evidence, identify research gaps, and discuss the implications for clinical practice and policy.

METHODS

To conduct this review, a comprehensive search was conducted across scientific databases, without any restrictions on the date or study type. Eligible studies examined the effectiveness of pharmacologic and nonpharmacologic treatments for IH and reported the outcomes of these interventions. Data from the studies were screened, analyzed, and synthesized to provide an overview of the available literature landscape.

RESULTS

Fifty-one studies were included in this review, which used various methods and interventions. Pharmacological treatments, particularly modafinil, have been frequently studied and have yielded positive results. There is also emerging evidence for alternative medications such as low-sodium oxybate and pitolisant. Nonpharmacological approaches, such as cognitive behavioral therapy for hypersomnia and transcranial direct current stimulation have also shown promise in managing IH.

CONCLUSIONS

This review highlights the complexity of managing IH symptoms and emphasizes the need for personalized multidisciplinary approaches. Pharmacological interventions are important in managing IH and can be complemented by nonmedication strategies. Larger-scale studies are necessary to advance our understanding of IH and to improve treatment outcomes.
