Obstructive sleep apnea-hypopnea syndrome complicated with idiopathic intracranial hypertension: a case report

Abstract

sleep rhythm, repeated apnea and arousal, or breathlessness; (II) daytime sleepiness; and (III) memory loss, and in severe cases, psychological, intellectual, and behavioral abnormalities. Idiopathic intracranial hypertension (IIH) is a syndrome characterized by increased intracranial pressure, with the main symptoms including headache, vision loss, visual field defect, pulsatile tinnitus, unsteady gait, and nausea/vomiting. The pathogenetic mechanism of IIH remains unclear but may involve aquaporin-4, vitamin A, and the regulatory mechanism of cerebrospinal fluid flow (1). So far, only a few studies have described IIH caused by OSAHS, although Zhan et al. (2) have published a relevant case report. The main symptoms of the patient whose cerebrospinal fluid pressure measured by lumbar puncture was 255 mmH 2 O were headache and blurred vision. However, the cerebrospinal fluid pressure of the patient with OSAHS complicated with IIH admitted to our hospital was higher and the main symptom was limb weakness. His
