Dizziness is a common complaint in ambulatory care, comprising 4% to 5% of all visits. AVS is characterized by rapid onset of vertigo, nausea/vomiting, nystagmus and head-motion intolerance. Vertigo is a symptom, not a diagnosis.
Hydrocephalus is a condition thatâs also known as water on the brain. Hydrocephalus can occur in older children and adults, particularly older adults.
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.
