Periventrikulaarinen

Periventrikulaarinen refers to a location in the brain surrounding the ventricles. The ventricles are a series of interconnected cavities within the brain that contain cerebrospinal fluid. These structures play a crucial role in the production, circulation, and absorption of cerebrospinal fluid, which protects the brain and spinal cord. The periventricular region is therefore the area immediately adjacent to these fluid-filled spaces. This region is significant in neuroanatomy and neuroimaging. Due to its proximity to the ventricles, conditions affecting the cerebrospinal fluid system can also impact the periventricular tissues. For example, conditions like hydrocephalus, where there is an abnormal accumulation of cerebrospinal fluid, can lead to increased pressure and stretching of the periventricular white matter. Changes in the periventricular white matter are often observed in various neurological disorders and are a common focus in medical imaging studies, such as MRI. The term is used by clinicians and researchers to describe findings or lesions located in this specific part of the brain.
