Duloxetine-induced rapid eye movement sleep behavior disorder: a case report
نویسندگان
چکیده
BACKGROUND Tricyclic antidepressants and selective serotonin reuptake inhibitors have been reported to induce the symptoms of rapid eye movement (REM) sleep behavior disorder (RBD) or to exacerbate REM sleep without atonia. With this case report, we found an association between typical RBD and duloxetine, a serotonin-noradrenaline reuptake inhibitor. CASE PRESENTATION We present a case of a 62-year-old woman who experienced enactment behaviors with violent dreams that were associated with increased tonic or phasic chin electromyography activity during REM sleep after treated with duloxetine. RBD symptoms were gradually reduced and completely ceased after discontinuation of duloxetine for 37 days. CONCLUSION The current case appears to be the first observation of duloxetine-induced RBD. We describe features of RBD induced by duloxetine that are similar and different from that induced by tricyclic antidepressants and selective serotonin reuptake inhibitors.

GBA mutations are associated with Rapid Eye Movement Sleep Behavior Disorder
Rapid eye movement sleep behavior disorder and GBA mutations are both associated with Parkinson's disease. The GBA gene was sequenced in idiopathic rapid eye movement sleep behavior disorder patients (n = 265), and compared to controls (n = 2240). Rapid eye movement sleep behavior disorder questionnaire was performed in an independent Parkinson's disease cohort (n = 120). GBA mutations carriers...
متن کاملInsulinoma Masquerading as Rapid Eye Movement Sleep Behavior Disorder
Insulinoma is a rare endocrine tumor that can cause a wide variety of symptoms, including abnormal nocturnal behavior. We report on 3 patients with insulinoma who presented with abnormal nocturnal behavior and injury during sleep, which simulated rapid eye movement (REM) sleep behavior disorder (RBD). In case 1, the fasting glucose level was 15 mg/dL, and insulin levels were elevated (15 μU/m...

متن کاملIctal SPECT in patients with rapid eye movement sleep behaviour disorder.
Rapid eye movement sleep behaviour disorder is a rapid eye movement parasomnia clinically characterized by acting out dreams due to disinhibition of muscle tone in rapid eye movement sleep. Up to 80-90% of the patients with rapid eye movement sleep behaviour disorder develop neurodegenerative disorders within 10-15 years after symptom onset. The disorder is reported in 45-60% of all narcoleptic...
