Patients presenting to the emergency department (ED) with a chief complaint of headache are common and are frequently clinically challenging. The primary role of ED physicians is to discriminate between the most common primary benign headaches and secondary potentially life-threatening headaches. There are several tools at the physician's disposal to(More)
Rapid-eye movement (REM) sleep behaviour disorder (RBD) is an REM sleep parasomnia characterized by enactment of dream content during REM sleep associated with loss of muscle atonia. RBD can be either idiopathic or secondary to drugs or other diseases. The best recognized association is with neurodegenerative diseases, namely alpha-synucleinopathies. RBD(More)
We investigated whether in human subjects, the pattern of coupling between the spontaneous fluctuations of heart period (HP) and those of systolic blood pressure (SBP) differs among wake-sleep states. Polysomnographic recordings and finger blood pressure measurements were performed for 48 h in 15 nonobese adults without sleep-disordered breathing. The(More)
We used multimodal magnetic resonance (MR) techniques [brain diffusion-weighted magnetic resonance imaging, diffusion-weighted imaging (DWI), proton MR spectroscopy (MRS), (1)H-MRS; and skeletal muscle phosphorous MRS, (31)P-MRS] to investigate interictal brain microstructural changes and tissue energy metabolism in four women with genetically determined(More)
OBJECTIVE Severity of obstructive sleep apnea (OSA) has been associated with poorer glycemic control in type 2 diabetes. It is not known whether obstructive events during rapid eye movement (REM) sleep have a different metabolic impact compared with those during non-REM (NREM) sleep. Treatment of OSA is often limited to the first half of the night, when(More)
BACKGROUND Previous studies suggest that patients with Chronic Daily Headache (CDH) have higher levels of anxiety and depressive disorders than patients with episodic migraine or tension-type headache. However, no study has considered the presence of psychiatric comorbidity in the analysis of personality traits. The aim of this study is to investigate the(More)
Narcolepsy with cataplexy (NC) is a sleep disorder caused by the loss of the hypothalamic neurons producing hypocretin. The clinical hallmarks of the disease are excessive daytime sleepiness, cataplexy, other rapid eye movement (REM) sleep phenomena, and a fragmented wake-sleep cycle. Experimental data suggest that the hypocretin system is involved(More)
Serotonin is involved in several central nervous system functions including pain threshold, mood regulation and drug reward. Overuse of acute medications is commonly identified as a causative factor for medication overuse headache (MOH). Apparently, MOH shares with other kinds of drug addiction some common neurobiological pathways. The objective of this(More)
