Evidence of increased restless legs syndrome occurrence in chronic and highly disabling migraine.

The existence of an association between migraine and restless legs syndrome (RLS) has recently been reported, although the possible implications of this for migraine clinical presentation remain poorly understood. The objectives of this study were to determine RLS frequency in a population of migraineurs compared with healthy subjects and to assess RLS occurrence in episodic versus chronic migraine patients; the relationship between migraine-related disability and RLS comorbidity was also evaluated. Two hundred and seventy-seven consecutive migraineurs (ICHD-II, 2004) were enrolled and compared with 200 controls; migraine was episodic in 175 and chronic in 102 patients.

Risk and Determinants of Dementia in Patients with Mild Cognitive Impairment and Brain Subcortical Vascular Changes: A Study of Clinical, Neuroimaging, and Biological Markers-The VMCI-Tuscany Study: Rationale, Design, and Methodology.

Dementia is one of the most disabling conditions. Alzheimer's disease and vascular dementia (VaD) are the most frequent causes. Subcortical VaD is consequent to deep-brain small vessel disease (SVD) and is the most frequent form of VaD.

Oxidative stress biomarkers in patients with untreated obstructive sleep apnea syndrome.

Background: The pathogenic role of oxidative stress in obstructive sleep apnea syndrome (OSAS) is still a matter of debate, with different studies obtaining contrasting results.

Methods: The aim of the present study was to evaluate three well-known markers of oxidative stress (advanced oxidation protein products [AOPP], ferric reducing antioxidant power [FRAP], and total glutathione [GSH]) in a cohort of 41 untreated patients with a new diagnosis of OSAS.

Results: We observed that OSAS patients showed increased protein oxidative damage and impaired antioxidant defenses.

Sleep-related migraine occurrence increases with aging.

A preferential occurrence of attacks at night-time or during early morning is documented in migraine without aura, suggesting a relationship between migraine and sleep and an impairment of circadian rhythms. The objective of this study was to verify the occurrence of sleep-related migraine in a large sample of migraineurs divided in different age groups and to evaluate the possible role of physiological variables (i.e.

Prevalence of sleep disturbances in mild cognitive impairment and dementing disorders: a multicenter Italian clinical cross-sectional study on 431 patients.

Background/aims: Sleep disturbances are common in the elderly and in persons with cognitive decline. The aim of this study was to describe frequency and characteristics of insomnia, excessive daytime sleepiness, sleep-disordered breathing, REM behavior disorder and restless legs syndrome in a large cohort of persons with mild cognitive impairment or dementia.

Methods: 431 consecutive patients were enrolled in 10 Italian neurological centers: 204 had Alzheimer's disease, 138 mild cognitive impairment, 43 vascular dementia, 25 frontotemporal dementia and 21 Lewy body dementia or Parkinson's disease dementia.
