Cardio exercises strengthen the muscles that support your knee and increase flexibility. Weight training and stretching do, too. For cardio, some good choices include walking, swimming and water aerobics, stationary cycling and elliptical machines. Tai chi may also help ease stiffness and improve balance.
Hydrocephalus is a buildup of fluid inside the skull that leads to brain swelling. Hydrocephalus means water on the brain.
The term hydrocephalus is derived from the Greek words hydro meaning water and cephalus meaning head. As the name implies, it is a condition in which the primary characteristic is excessive accumulation of fluid in the brain. Although hydrocephalus was once known as water on the brain, the water is actually cerebrospinal fluid (CSF)--a clear fluid that surrounds the brain and spinal cord. The excessive accumulation of CSF results in an abnormal widening of spaces in the brain called ventricles.
