Brain Anomaly and Plasticity: Hydrocephalus

Hydrocephalus, a childhood disorder of excess fluid in the brain, illustrates brain plasticity — the brain’s amazing ability to rebound after injury. While patients with this disorder experience compression and destruction of brain tissue early in life, many are able to function normally later in life, after their brains have compensated for the loss.
