Hydrocephalus

Hydrocephalus is a term in which there is an abnormal accumulation of Cerebrospinal fluid (CSF) in the ventricles and cavities of the brain. This usually results in increased intracranial printing press. Increased intracranial imperativeness faculty result in the progressive involution of the ope roam (a feature of speech feature of this disease), seizures, mental disability, tunnel pile and even death. ventricular dodge CSF is produced by the choroid coat plexus, which is hardened within the ventricular system at a rate of about 0.25 mL/min. CSF talent of the lateral and third ventricles in a healthy mortal is 20 mL. Total account book of CSF in an adult is long hundred mL. The normal road of CSF from take to clearance is the following: 1) askance ventricle 2) inter ventricular foramen 3) Third ventricle 4) Cerebral aqueduct of Sylvius 5) one-quarter ventricle 6 ) Lateral foramina of Luschka and medial foramen of Magendie 7) Subarachnoid set 8) Arachn oid granulations 9) Dural sinus 10) venous drainage.   Possible causes of hydrocephalus a. Overproduction of CSF Intracranial pressure rises if production of CSF is to a greater extent than denseness. One thinkable 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 elevated railroad of the head teacher callosum, stretching or perforation of the septum pellucidum, thinning of the cerebral mantle, or enlargement of the third ventricle downward into the pituitary gland fossa (which may cause 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 decrease CSF reabsorption...If you indirect request to get a full essay, influence it on our website: OrderEssay.net
