High Blood Pressure

The Relationship between Lateral Ventricles in the Brain and Hypertension

Lateral ventricles in brain and hypertension show the relationship between changes in the sizes of lateral ventricles and intracranial hypertension. It has been observed that amplification in the intracranial blood pressure lead to compression of the brain and reduction in cerebral blood flow. As the pressure of intracranial hypertension increases, the contents of the skull including lateral ventricles do not remain in place. Focal boosting of blood pressure results in focal deviations in the lateral ventricles.  

Lateral ventricles will be enlarged under high blood pressure as a result of obstruction in the flow of blood. But when the pressure is in compartments other than the lateral ventricles, the lateral ventricles will be compressed and even demolished. This is usually the case in diseases like subdural hematoma, epidural hematoma, generalized cerebral edema etc.

An instant CT scan has to be carried out if intracranial hypertension is inferred in order to guess the degree of changes in the lateral ventricles. This will help to identify the cause of the changes and determine the severity of intracranial hypertension.

Studies have been carried out to determine whether hypertension leads to changes in the lateral ventricles. This is important as hypertension is the main risk factor for lethal stroke and other heart and kidney diseases. It has been found out from the studies that people with hypertension are more likely to have larger left and right lateral ventricles.     

As intracranial blood pressure increases, the hypertensive individual has a greater risk of brain dysfunction. Lateral ventricles change in sizes with hypertension. In hypertensive people, the volume of the lateral ventricles remains significantly larger. It has also been found from the studies that changes in the lateral ventricles are not related to age or duration of hypertension or to the use of diuretics as anti-hypertensive drugs. But it is also true that prolonged hypertension usually leads to structural changes in the brain. What we need now are longitudinal studies that can determine if  hypertensive individuals are at an increased risk of  brain dysfunction.
