P.S. issue is Hydrocephalus comes from the Greek words: Hydro meaning water and cephalus meaning head.
Hydrocephalus is a chronic, neurological condition caused by an abnormal accumulation of cerebrospinal fluid (CSF) within cavities of the brain called ventricles, resulting in pressure on the brain.
It affects over 1 million Americans, ranging from infants and older children to young and middle-aged adults, as well as seniors.
There is currently no cure for hydrocephalus, but it can be treatable.
Cerebrospinal fluid (CSF) is produced in the ventricles and in the choroid plexus. It circulates through the ventricular system in the brain and is absorbed into the bloodstream. CSF is in constant circulation and has many functions. It surrounds the brain and spinal cord and acts as a protective cushion against injury. CSF contains nutrients and proteins that are needed for the nourishment and normal function of the brain. It carries waste products away from surrounding tissues.
Hydrocephalus occurs when there is an imbalance between the amount of CSF that is produced and the rate at which it is absorbed.

SO having shunt inserted, to return to normal gait and balance. I think I've had the condition for much of my life, and has become burdensome 'lately.'
