Hydrocephalus :
The brain receives nutrients and removes its waste via a fluid known as the cerebrospinal fluid (CSF). This fluid flows through areas of the brain called the ventricles, and it also flows in the spinal cord. The body generates new CSF daily and absorbs the same amount. Hydrocephalus is a condition in which the normal production or absorption of CSF is blocked. Its symptoms depend on the patient's age and the severity of the disease. Some common symptoms include headaches, vision problems, and vomiting. This condition may be present since birth due to complications of premature birth, spinal cord defects, or infections during pregnancy. It can develop later in life due to a stroke, tumour or head trauma. Brain and spine infections such as meningitis can also cause hydrocephalus. The disease can be detected with CT and MRI scans and treated with surgery.
