Reducción del volumen del flujo sanguíneo cerebral en pacientes con demencia vascular
Lancet (London, England)
|December 28, 1999
Resumen
El flujo sanguíneo cerebral se reduce significativamente en pacientes con demencia vascular en comparación con individuos sanos. La ecografía dúplex en color revela un menor flujo sanguíneo cerebral global en este grupo de pacientes.
Área de la Ciencia:
- Neurología Neurología.
- La medicina vascular es una medicina vascular.
- Imágenes médicas de imágenes médicas.
Sus antecedentes:
- La demencia vascular es una causa común de deterioro cognitivo.
- El flujo sanguíneo cerebral (FCB) es crucial para la función cerebral.
- La evaluación de la CBF puede ayudar a comprender la fisiopatología de la demencia.
Objetivo del estudio:
- Para investigar el flujo sanguíneo cerebral global en pacientes con demencia vascular.
- Para comparar la CBF entre pacientes con demencia vascular y controles sanos.
Principales métodos:
- Se utilizó la ecografía dúplex a color para medir el flujo sanguíneo de la arteria cerebral extracraneal.
- Se incluyeron pacientes diagnosticados con demencia vascular y individuos sanos de la misma edad y sexo.
Principales resultados:
- Los pacientes con demencia vascular presentaron un flujo sanguíneo cerebral global significativamente más bajo.
- La diferencia en la CBF fue estadísticamente significativa en comparación con los controles sanos.
Conclusiones:
- El flujo sanguíneo cerebral global se reduce notablemente en las personas con demencia vascular.
- Este hallazgo apoya el papel del compromiso cerebrovascular en la demencia vascular.
- La ecografía dúplex en color es una herramienta viable para evaluar la CBF en esta población.

Overview
01:29Blood Flow
Blood is pumped by the heart into the aorta, the largest artery in the body, and then into increasingly smaller arteries, arterioles, and capillaries. The velocity of blood flow decreases with increased cross-sectional blood vessel area. As blood returns to the heart through venules and veins, its velocity increases. The movement of blood is encouraged by smooth muscle in the vessel walls, the movement of skeletal muscle surrounding the vessels, and one-way valves that prevent backflow.
01:14Decreased pulse rate
Bradycardia is a medical condition in which the heart rate is slower than normal. It occurs when the heart's natural pacemaker, the sinus node, generates slower electrical impulses than the standard rhythm. In adults, bradycardia is diagnosed when the pulse rate falls below 60 beats per minute, indicating a deviation from the normal heart rate range.
There are specific risk factors that can elevate the likelihood of developing bradycardia. Advanced age is a significant factor, with bradycardia...

01:26Transient Ischemic Attack l: Introduction
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
01:22Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
01:22Dementia l: Introduction
Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...
