Is It Normal To Get Communicating Hydrocephalus At The Age

is it normal to get communicating hydrocephalus at the age of 20?can a vp shunt ever be removed if inserted in 20's? inserting a shunt is just an alternative to cure but not actually the cure. is there any method to cure it so that the brain absorption starts functioning properly and the shunt can be removed. what is the life expectancy of such people? can they carry on normally with their lives post surgery? i have been prescribed levipill 500mg for 6 months what is the actual use of this medicine?
