BACKGROUND Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) and short-lasting unilateral neuralgiform headache with cranial autonomic symptoms (SUNA) are primary headache syndromes. A growing body of literature has focused on brain magnetic resonance imaging (MRI) evidence of neurovascular compression in(More)
STUDY OBJECTIVE Narcolepsy with cataplexy (NC) is associated with loss of hypocretin neurons in the lateral hypothalamus involved in the circadian timing of sleep and wakefulness, and many biologic functions including autonomic control. The authors investigated whether chronic lack of hypocretin signaling alters cardiovascular control during sleep in(More)
It has been proposed that European mitochondrial DNA (mtDNA) haplogroups J and K, and their shared 10398G single-nucleotide polymorphism (SNP) in the ND3 gene, are protective from Parkinson's disease (PD). We evaluated the distribution of the different mtDNA haplogroups in a large cohort of 620 Italian patients with adult-onset (>50, <65 years of age)(More)
Recent literature indicates that the vitamin K cycle plays a role in the calcification process, presumably via its intervention on gamma-carboxylation of the noncollagenous proteins of bone osteocalcin and matrix gamma-carboxyglutamic acid protein. The major clinical evidence of this interference is fetal bone defect caused by oral anticoagulants given to(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)
OBJECTIVES To assess whether family history for chronic headache (CH) and drug overuse could represent a risk factor for headache chronification. BACKGROUND Among factors investigated as risk factors for chronification of headache disorders, familial liability for CH and drug overuse has been rarely investigated. PATIENTS AND METHODS A total of 105(More)
Hypo and hyperactivity of the autonomic nervous system have been associated with chronic bowel inflammation diseases. We investigated the autonomic function in 11 patients with chronic ulcerative colitis (UC) and 17 healthy controls by means of cardiovascular autonomic tests and heart rate variability. Autonomic responses were normal in patients and(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)
Spontaneous intracranial hypotension (SIH) is a syndrome of low cerebrospinal fluid (CSF) pressure characterised by postural headaches in patients without any history of dural puncture or penetrating trauma. Described by Schaltenbrand in 1938, SIH is thought to result from an occult CSF leak resulting in decreased CSF volume and, consequently, in low CSF(More)
