Hydrocephalus is a medical condition characterized by the accumulation of cerebrospinal fluid within the brain, leading to increased pressure that can cause brain damage. This condition can occur at any age, but is most commonly diagnosed in infants and older adults. The main symptoms of hydrocephalus include headache, nausea, vomiting, blurred vision, and difficulty with balance and coordination. Treatment options for hydrocephalus typically involve surgical intervention to drain the excess fluid and alleviate pressure on the brain. Ongoing research in this area focuses on improving diagnostic techniques, developing new surgical procedures, and finding alternative treatments to manage the condition more effectively.
