What Are the Symptoms of Water on the Brain?

The symptoms of water on the brain, or hydrocephalus, include sleepiness, vomiting, irritability, headaches, poor balance and poor appetite, states Mayo Clinic. Other symptoms include impaired vision, memory loss and loss of bladder control. Particular symptoms of hydrocephalus usually differ depending on the age of onset.

When hydrocephalus develops in infants, distinct symptoms include an abnormally large head, eyes fixed downward and insufficient muscle tone and strength. In toddlers and older children, symptoms include difficulty waking up or remaining awake and blurred vision, notes Mayo Clinic. Young and middle-aged adults experience a decrease in memory, concentration and other skills that affect productivity. Symptoms in older adults include slower than normal movements, walking difficulties and a decline in thinking and reasoning capabilities.
