Also, cerebrospinal fluid circulates nutrients and gets rid of squander products from the CNS. Cerebrospinal fluid is generated continually during the ventricles, circulates through the CNS, and is also then reabsorbed with the bloodstream. If too much cerebrospinal fluid is made, its movement is blocked, or not plenty of is reabsorbed, the system turns into outside of balance and it visit could Construct up inside the ventricles. This causes an enlargement from the ventricles referred to as hydrocephalus that will place stress over the Mind, causing the kinds of neurological problems that former professional soccer player Jayson, explained to start with of this chapter, is struggling from.
As a way to handle him correctly, Jayson’s Health professionals needed to do numerous tests to determine the precise cause of his signs or symptoms.
