👉 Hydrocephaly is a medical condition that occurs when there's an extra or too much fluid in the brain. This can make it hard for the brain to work properly and can lead to other problems, such as trouble with vision, balance, coordination, and hearing. It's often caused by a blockage of the水管或静脉，导致血液不能正常流入大脑。这种疾病可以通过手术来治疗。
