Hydrocephalus needs to be treated clinically with medications, specific drugs include diuretics such as dihydrochlorothiazide, tachyphylaxis, and mannitol. Most patients with moderate hydrocephalus can be treated with sorbitol, a drug that is relatively less irritating to the patient. If the disease develops with arachnoid adhesions, it can be treated with hormones and prompt anti-inflammatory and antibacterial treatment. Surgical treatment can also be used, with repeated punctures and drainage through the lumbar spine to allow the fluid in the brain to permeate out from there. Other surgical treatments are indicated for symptoms of high pressure in the brain. Surgery mainly includes decongestion surgery, cerebrospinal fluid shunt, the former being the preferred method for treating hydrocephalus, and the latter requiring zoning according to the site of hydrocephalus. Although surgery is effective, it is prone to postoperative complications, such as infection, epilepsy, and optic nerve damage.
