Purpose of review: Sleep disturbances, particularly obstructive sleep apnea (OSA), may have a significant impact on the outcomes of patients with idiopathic intracranial hypertension (IIH). We conducted a PRISMA-compliant systematic literature review to study sleep disturbance in adult patients with IIH.
Recent findings: The current literature on the relationship between IIH and sleep is quite limited. Research has found that sleep disturbances are associated with lower quality of life and may worsen several symptoms associated with IIH, such as headache, cognitive deficits, and neuropsychiatric issues.
Summary: OSA was more prevalent in patients with IIH than in healthy controls. Several studies found that OSA was associated with worse IIH symptoms and treatment of OSA helped improve these parameters. Limitations included available literature and heterogeneity in sleep metrics and OSA diagnostic criteria between studies. Overall, further study of sleep disturbances in patients with IIH may encourage earlier screening, improved treatment options, and long-term improvements in quality of life.
