In neuroanatomy, the ventricular system is a set of four interconnected cavities known as cerebral ventricles in the brain. [1] [2] Within each ventricle is a region of choroid plexus which produces the circulating cerebrospinal fluid (CSF). The ventricular system is continuous with the central canal of the spinal cord from the fourth ventricle ...
Ventriculitis is caused by an infection of the ventricles, causing an immune response in the lining, which in turn, leads to inflammation. The ventriculitis, is in truth, a complication of the initial infection or abnormality. The underlying infection can come in the form of a number of different bacteria or viruses.
Grade III - ventricles are enlarged by the accumulated blood; Grade IV - bleeding extends into the brain tissue around the ventricles; Grades I and II are most common, and often there are no further complications. Grades III and IV are the most serious and may result in long-term brain injury to the infant.
Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
Hydrocephalus is usually due to blockage of CSF outflow in the ventricles or in the subarachnoid space over the brain. In a person without hydrocephalus, CSF continuously circulates through the brain, its ventricles and the spinal cord and is continuously drained away into the circulatory system. Alternatively, the condition may result from an ...
This category includes intraparenchymal hemorrhage, or bleeding within the brain itself, and intraventricular hemorrhage, bleeding within the brain's ventricles (particularly of premature infants). Intra-axial hemorrhages are more dangerous and harder to treat than extra-axial bleeds. [ 8 ]
Some cases of cerebellar hemorrhage lead to blockage of the fourth ventricle with subsequent impairment of drainage of cerebrospinal fluid from the brain. [7] The ensuing hydrocephalus, or fluid buildup in the ventricles of the brain leads to a decreased level of consciousness, total loss of consciousness, coma, and persistent vegetative state. [7]
Similarly, ventricular enlargement—which reflects atrophy of surrounding brain regions—is also reduced in abstinent alcoholics. Following extended sobriety , the volume of the lateral and third ventricles was decreased, and abstainers showed an improvement in working memory and balance. [ 16 ]
