The main treatment options for mild hydrocephalus are dynamic review and observation, medication, and surgery if necessary. 1. Dynamic review and observation: mild hydrocephalus generally has little effect on patients, so regular review and dynamic observation is also a feasible solution. It is mainly an outpatient review, and a review of CT or MRI once every 3 months or so, to pay attention to the intellectual level, walking gait, and urinary and fecal self-care. 2. Medication: For mild hydrocephalus, oral acetazolamide can be considered, which can inhibit the secretion of cerebrospinal fluid, thus playing a certain role in treating hydrocephalus. 3. Surgical treatment: For hydrocephalus patients whose follow-up examination shows gradual enlargement of the ventricular system, gradual decline of intelligence level, or gait abnormality and incontinence, ventriculoperitoneal shunt surgery should be actively considered. The treatment of mild hydrocephalus should be standardized under the guidance of a professional physician, and should not be evaluated and treated by oneself.
