Hydrocephalus

Hydrocephalus is a consideration in which there is an brachydactylous accumulation of Cerebrospinal fluid (CSF) in the ventricles and cavities of the brain. This usually results in increased intracranial printing press. Increased intracranial closet faculty result in the progressive involution of the transmit (a feature of speech feature of this disease), seizures, mental disability, tunnel mint and even death. ventricular dodge CSF is produced by the choroid plexus, which is set(p) within the ventricular system at a locate of about 0.25 mL/min. CSF talent of the lateral and third ventricles in a healthy mortal is 20 mL. Total mountain of CSF in an adult is long hundred mL. The normal route of CSF from take to clearance is the following: 1) askance ventricle 2) screen ventricular foramen 3) Third ventricle 4) Cerebral aqueduct of Sylvius 5) one-fourth ventricle 6 ) Lateral foramina of Luschka and medial foramen of Magendie 7) Subarachnoid plaza 8) Arac hnoid granulations 9) Dural fistulous withers 10) venous drainage.   Possible causes of hydrocephalus a. Overproduction of CSF Intracranial pressure rises if production of CSF is to a great extent than denseness. One workable cause is that CSF whitethorn be overproduced. In this case resistance to CSF flow, or venous sinus pressure may be increased as a result.

CSF production will decrease as ICP rises. The brain compensates by absorption of CSF across ventricles. Temporal horns dilate asymmetrically, resulting in whirligig of the head teacher callosum, stretching or perforation of the septum pellucidum, thinning of the rational mantle, or enlargement of the third ventricle dow nward into the pituitary fossa (which may c! ause pituitary dysfunction). A possible cause of unjustified CSF production might a condition known as choroid plexus papilloma, where the increase in CSF production is caused by an abnormal growth in the choroid plexus. b. hinderance of CSF Pathways Obstruction of CSF pathways  (usually in the fourth ventricle) may lead to decreased CSF reabsorption...If you indirect request to get a full essay, piece it on our website: OrderEssay.net
