Migraine has been associated with an increased risk for ischemic stroke. A recent study suggests that a generalized peripheral vasoconstriction may represent one possible mechanism underlying the increased risk for ischemic stroke. The aim is to verify the presence of cerebral arteriolar vasoconstriction during the interictal period of migraine with (MA+)(More)
OBJECTIVE To evaluate if relative changes in the amplitude of the arterial pulse wave of the cerebral microcirculation (APWCM) measured by near-infrared spectroscopy (NIRS) may provide information about relative changes of cerebral blood flow (CBF) in cerebral cortex. METHODS In 10 healthy human volunteers, through simultaneous recording of the APWCM(More)
The aim of this study is to identify the pathophysiology of migraine attack with prolonged aura (between 1 h and 7 days) not clearly understood. We studied cortical cerebral microcirculation by an innovative near infrared spectroscopy system (NIRS) and cerebral macrocirculation by transcranial Doppler (TCD) in eight subjects (3 M and 5 F, age range 21-41(More)
BACKGROUND AND AIMS A large body of evidence indicates that cerebral hypoperfusion is one of the earliest signs in the development of Alzheimer's disease (AD). The aim of our study was to evaluate whether the brain reperfusion rehabilitation therapy (BRRT) would improve verbal memory and learning and/or global cognitive impairment in mild AD. METHODS(More)
The aim was to evaluate whether patients with episodic migraine with (MA+) and without aura (MA-), during the interictal period of migraine would have an altered distensibility of the wall of cerebral arterial network and whether it would play a role in migraine headache. To evaluate the distensibility of the wall of cerebral arterial network, we measured(More)
Due to the lack of markers for migraine, diagnosis relies entirely on symptomatology. The aim is to evaluate the utility of a new near-infrared spectroscopy parameter as potential marker for patients with episodic migraine with (MA+) and without aura (MA-) during the interictal period of migraine. We studied 10 patients with MA+ (age 39.5 ± 12.2 years) and(More)
OBJECTIVE To evaluate the utility of near-infrared spectroscopy (NIRS) and transcranial Doppler (TCD) parameters as potential markers for amnestic mild cognitive impairment (aMCI). METHODS By means of NIRS and TCD, noninvasive and inexpensive technologies, we studied 21 patients with aMCI (10 M and 11 F, 70.2 ± 7.3 years) and 10 age matched healthy(More)
