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 cerebrospinal fluid (CSF) is contained in the brain ventricles and the cranial and spinal subarachnoid spaces. The mean CSF volume is 150 ml, with 25 ml in the ventricles and 125 ml in subarachnoid spaces. CSF is predominantly, but not exclusively, secreted by the choroid plexuses. Brain interstitial fluid, ependyma and capillaries may also play a poorly defined role in CSF secretion.
