Middle Cerebral Artery Pulsatility Index is Associated with Cognitive Impairment in Lacunar Stroke

Pulsatility index in the middle cerebral artery- associated with cognitive impairment in lacunar stroke?

Plasma Total Homocysteine Level Is Associated with the Pulsatility Index of Cerebral Arteries in Lacunar Infarction

PURPOSE The pulsatility index (PI), measured by transcranial Doppler (TCD), is a surrogate marker for distal vascular resistance in cerebral arteries, and elevated plasma total homocysteine (tHcyt) is regarded as a cause of ischemic stroke, including lacunar infarction. We investigated the relationship between the PI of cerebral arteries and plasma tHcyt in patients with lacunar infarction. M...

Cognitive Impairment in Ischaemic Lacunar Stroke

Ischaemic cerebral small-vessel disease (SVD) can be visualised on brain magnetic resonance imaging (MRI) scans as lacunar infarcts, white matter hyperintensities and cerebral microbleeds, and has been recognised as the most frequent cause of cognitive impairment of vascular origin. Lacunar infarction is the most common manifestation of SVD and accounts for approximately 25 % of all brain infar...

Lacunar Infarction in Type 2 Diabetes Is Associated with an Elevated Intracranial Arterial Pulsatility Index

PURPOSE The arterial pulsatility index (PI) is measured by transcranial Doppler ultrasonography (TCD) and is postulated to reflect the vascular resistance distal to the artery being examined. An increased PI of the intracranial artery is often reported with diabetes mellitus (DM), old age, hypertension, intracranial hypertension, vascular dementia, and small artery disease. Microvascular compli...

Dynamic cerebral autoregulation in acute lacunar and middle cerebral artery territory ischemic stroke.

BACKGROUND AND PURPOSE We addressed whether dynamic cerebral autoregulation (dCA) is affected in middle cerebral artery (MCA) territory (MCAS) and lacunar ischemic stroke (LS). METHODS Blood pressure (MAP) and MCA velocity (V) were measured in 10 patients with large MCAS (National Institutes of Health Stroke score, 17+/-2; mean+/-SEM), in 10 with LS (score, 9+/-1), and in 10 reference subject...
